A tribute to blacklisted lyricist who put the rainbow in The Wizard of Oz


Judy Garland in MGM's 'The Wizard of Oz'

Amy Goodman and Democracy Now
December 27, 2024

His name might not be familiar to many, but his songs are sung by millions around the world. Today, we take a journey through the life and work of Yip Harburg, the Broadway lyricist who wrote such hits as “Brother, Can You Spare a Dime?” and who put the music into The Wizard of Oz, the movie that inspired the hit Broadway musical and now Hollywood blockbuster, Wicked. Born into poverty on the Lower East Side of Manhattan, Harburg always included a strong social and political component to his work, fighting racism and poverty. A lifelong socialist, Harburg was blacklisted and hounded throughout much of his life. We speak with Harburg’s son, Ernie Harburg, about the music and politics of his father. Then we take an in-depth look at The Wizard of Oz, and hear a medley of Harburg’s Broadway songs and the politics of the times in which they were created



This is a rush transcript. Copy may not be in its final form.


AMY GOODMAN: Today, we pay tribute to Yip Harburg. His name may not be familiar to many, but his songs are sung by millions around the world, like jazz singer Abbey Lincoln.
ABBEY LINCOLN: Bing Crosby sang it, Ike Quebec played it, and Yip Harburg wrote it.

[singing] Once I built a railroad, made it run
Made it race against time
Once I built a rairoad, now it’s done
Brother, can you spare a dime?

AMY GOODMAN: And Tom Waits.
TOM WAITS: [singing] Once I built a tower way up to the sun
With bricks and mortar and lime.


AMY GOODMAN: Judy Collins, and Dr. John from New Orleans, Peter Yarrow.

AL JOLSON: [singing] Say, don’t you remember,
Don’t you remember they called me Al
It was Al, Al all the time.


AMY GOODMAN: That’s Al Jolson. And our beloved Odetta.
ODETTA: [singing] Don’t you remember, I’m your pal
Say, brother, can you spare a dime?
Buddy, can you spare a dime?


AMY GOODMAN: “Brother, Can You Spare a Dime?” may well be a new anthem for many Americans. The lyrics to that classic American song were written by Yip Harburg. He was blacklisted during the McCarthy era. During his career as a lyricist, Yip Harburg used his words to express antiracist, pro-worker messages. He’s best known for writing the lyrics to The Wizard of Oz, the movie that inspired the hit Broadway musical and now the Hollywood blockbuster film Wicked. Yip Harburg also had two hits on Broadway: Bloomer Girls, about the women’s suffrage movement, and Finian’s Rainbow, a kind of immigrants’ anthem about race and class and so much else.


Today, in this Democracy Now! special, we pay tribute to Yip Harburg’s life. Ernie Harburg is Yip’s son and biographer. He co-wrote the book Who Put the Rainbow in The Wizard of Oz?: Yip Harburg, Lyricist. I met up with Ernie Harburg at the New York Public Library for Performing Arts at Lincoln Center years ago when they are exhibiting Yip Harburg’s work. Ernie Harburg took me on a tour.
ERNIE HARBURG: The first place is business about words, and one of them is that the songs, when they were written back in those days, anyhow, always had a lyricist and a composer, and neither one of them wrote the song. They both wrote the song. However, in the English language, you know, you have “This is Gershwin’s song,” or “This is” — they usually say the composer’s song. I’ve rarely ever heard somebody say, “This is Yip Harburg’s song” or “Ira Gershwin’s song.” Both of them would be wrong. The fact is, two people write a song.

So I’m going to talk about Yip’s lyrics and then lyrics in the song. Now the first thing we’re looking at here is an expression really of Yip’s philosophy and background, which he brings to writing lyrics for the songs. And what it says here is that songs have always been man’s anodyne against tyranny and terror. The artist is on the side of humanity from the time that he was born a hundred years ago in the dire depths of poverty that only the Lower East Side in Manhattan could have when the Russian Jews, about 2 million of them, got up out of the Russian shtetls and ghettos, and the courageous ones came over here and settled in that area, what we now know as the East Village. And Yip knew poverty deeply, and he quoted Bernard Shaw as saying that the chill of poverty never leaves your bones. And it was the basis of Yip’s understanding of life as struggle.

AMY GOODMAN: Let’s go back to how Yip got his start.


ERNIE HARBURG: Yip was, at a very early age, interested in poetry, and he used to go to the Tompkins Square Library to read, and the librarians just fed him these things. And he got hooked on every one of the English poets, and especially O. Henry, the ending. He always has a little great ending on the end of each of his songs. And he got hooked on W.S. Gilbert, The Bab Ballads.

And then, when he went to Townsend High School, they had them sitting in the seats by alphabetical order, so Yip was “H” and Gershwin was “G”, so Ira sat next to Yip. One day, Yip walked in with The Bab Ballads, and Ira, who was very shy and hardly spoke with anybody, just suddenly lit up and said, “Do you like those?” And they got into a conversation, and Ira then said, “Do you know there’s music to that?” And Yip said, “No.” He said, “Well, come on home.”

So they went to Ira’s home, which was on 2nd Avenue and 5th Street which is sort of upper from Yip’s poverty at 11th and C. And they had a Victrola, which is like having, you know, huge instruments today, and played him H.M.S. Pinafore. Well, Yip was just absolutely flabbergasted, knocked out. And that did it. I mean, for the both of them, because Ira was intensely interested that thing, too.

That began their lifelong friendship. Then Ira went on to be one of the pioneers, with 25 other guys, Jewish Russian immigrants, who developed the American Musical Theater. And it was only after — in 1924, I think, that Ira’s first show with George Gershwin, his brother, that they started writing together.


AMY GOODMAN: The Gershwins’ Porgy and Bess in 1940.

ERNIE HARBURG: Yip’s career took a kind of detour, because when the war, World War I, came and Yip was a socialist and did not believe in the war, he took a boat down to Uruguay for three years. I mean, he refused to fight in the thing. That’s shades of 1968 and the Vietnam War, right?

AMY GOODMAN: And why didn’t he believe in World War I?

ERNIE HARBURG: Because he was a full, deep-dyed socialist who did not believe that capitalism was the answer to the human community and that indeed it was the destruction of the human spirit. And he would not fight its wars. And at that time, the socialists and the lefties, as they were called, Bolsheviks and everything else, were against the war.

And so, when he came back, he got married, he had two kids, and he went into the electrical appliance business, and all the time hanging out with Ira and George and Howard Dietz and Buddy De Sylva and writing light verse for the F.P.A Conning Tower. And the newspapers used to carry light verse, every newspaper. There were about 25 of them at that time, not two or three now owned by two people in the world, you know. And they actually carried light verse. Well, Yip and Ira and Dorothy Parker, the whole crowd, had light verse in there, and, you know, they loved it.

So, when the crash came and Yip’s business went under, and he was about anywhere from $50,000 to $70,000 in debt, his partner went bankrupt. He didn’t. He repaid the loans for the next 20 or 15 years, at least. Ira and he agreed that he should start writing lyrics.

AMY GOODMAN: Let’s talk about what Yip is most known for: Finian’s Rainbow, The Wizard of Oz. Right here, what do we have in front of us?

ERNIE HARBURG: We have a lead sheet. We are in the gallery of the Lincoln Center for the Performing Arts, and there’s an exhibition called “The Necessity of Rainbows,” which is the work of Yip Harburg. And we are looking at the lead sheet of “Brother, Can You Spare a Dime?” which came from a revue called Americana, which — it was the first revue, which was — had a political theme to it: at that time, the notion of the forgotten man. You have to remember what the Great Depression was all about. It’s hard to imagine that now. But when Roosevelt said, “One-third of the nation are ill-clothed, ill-housed and ill-fed,” that’s exactly what it was. There was at least 30% unemployment at those times. And among Blacks and minorities, it was 50, 60%. And there were breadlines and —

Now, the rich, you know, kept living their lifestyle, but Broadway was reduced to about 12 musicals a year from prior, in the '20s, about 50 a year, OK? So it became harder. But the Great Depression was deep down a fact of life in everybody's mind. And all the songs were censored — I use that loosely — by the music publishers. They only wanted love songs or escape songs, so that in 1929 you had “Happy Days Are Here Again,” and you had all of these kinds of songs. There wasn’t one song that addressed the Depression, in which we were all living. And this show, the Americana show, Yip was asked to write a song or get the lyrics up for a song which addressed itself to the breadlines, OK?

And so, he, at that time, was working very closely with Jay Gorney. Jay had a tune, which he had brought over with him when he was 8 years old from Russia, and it was in a minor key, which is a whole different key. Most popular songs are in major. And it was a Russian lullaby, and it was da, da, da, da, da, da, da, da, da. And Jay had — somebody else had lyrics for it: “Once I knew a big blonde, and she had big blue eyes. She was big blue” — like that. And it was a torch song, of which we talked about. And Yip said, “Well, could we throw the words out, and I’ll take the tune?” All right.

And if you look at Yip’s notes, which are in the book that I mentioned, you’ll see he started out writing a very satiric comedic song. At that time, Rockefeller, the ancient one, was going around giving out dimes to people, and he had a — Yip had a satiric thing about “Can I share my dime with you?” You know? But then, right in the middle, other images started coming out in his writings, and you had a man in a mill, and the whole thing turned into the song that we know it now, which is here and which I can read to you. And if you do this song, you have to do the verse, because that’s where a lot of the action is.

AMY GOODMAN: Can you sing it to me?

ERNIE HARBURG: All right, I’ll try. It won’t be as good as Bing Crosby or Tom Waits.

[singing] They used to tell me
I was building a dream,
And so I followed the mob,
When there was earth to plow
Or guns to bear,
I was always there
Right on the job.
They used to tell me
I was building a dream,
With peace and glory ahead,
Why should I be standing in line,
Just waiting for bread?

YIP HARBURG: [singing] Once I built a railroad
I made it run,
Made it race against time.
Once I built a railroad;
Now it’s done.
Buddy, can you spare a dime?

AMY GOODMAN: Yip Harburg singing in 1975.

YIP HARBURG: [singing] Once I built a tower
To the sun,
Brick and rivet and lime;
Once I built that tower;
Now it’s done.
Brother, can you spare a dime?

AMY GOODMAN: When was this song first played?

ERNIE HARBURG: In 1932. And in the Americana revue, every critic, everybody took it up, and it swept the nation. In fact, paradoxically, I think Roosevelt and the Democratic Party really wanted to tone it down and keep it off the radio, because playing havoc with trying to not talk about the Depression, which everybody did. You remember the Hoover thing, not only “Happy Days Are Here Again,” but “Two Chickens in Every Pot,” and so forth. Nobody wanted to sing about the Depression either, you know.

AMY GOODMAN: Yet, Yip Harburg was a supporter of FDR.

ERNIE HARBURG: Yes. But politics are politics, you know, and the thing was that, in fact, historically, this was, I would say, the only song that addressed itself seriously to the Great Depression, the condition of our lives, which nobody wanted to talk about and nobody wanted to sing about.


AMY GOODMAN: Ernie Harburg, son of Yip Harburg. When we come back from our break, we’ll talk about The Wizard of Oz, Finian’s Rainbow and other shows.

[break]

AMY GOODMAN: This is Democracy Now! I’m Amy Goodman. We continue with our special, on our journey through Yip Harburg’s life with his son, Ernie Harburg. Ernie talks about how Yip Harburg wrote the lyrics to The Wizard of Oz, the movie that inspired the hit Broadway musical Wicked and now the Hollywood film by the same name.
ERNIE HARBURG: Actually, Yip did more than the lyrics. When they were — when Yip and Harold Arlen were called in to do the score of The Wizard of Oz, it was Yip who had this executive experience in his electrical appliance business and also had become a show doctor, so he was — that is, when a show wasn’t working, you would call somebody and try to fix it up. He had an overview of shows and he had an executive talent. And so, he was always what they called a “muscle man” in a show, all right? And he’d already worked with Bert Lahr in a great song, “The Woodchopper’s Song,” and —

AMY GOODMAN: Wait a second. Bert Lahr, the lion?

ERNIE HARBURG: The lion. Bert Lahr and most of these people were from vaudeville and burlesque. And Yip knew them in the ’20s, but he actually worked with Bert Lahr in this light — Walk a Little Faster and another revue. I forget that name, but he and — Yip and Arlen gave Bert songs to sing, which allowed him to satirize the opera world, if you want, or a send-off of rich, you know. And so, they had that relationship.

Also, Yip knew Jack Haley, the tin woodman. And Yip also worked with Bobby Connolly as a choreographer in the early '30s on his shows, who was also the choreographer for The Wizard of Oz. So he had a cast here with Arlen who were, you know, sort of Yip's men. You know what I mean? So, when Yip went to Arthur Freed, the producer, who was too busy to work on this musical, and Mervin LeRoy had nothing to do with it, practically, because he had never done a musical before, so it became a vacuum in which the lyricist entered, because he was all ready to do so. Yip was always an active, you know, organizer.

And so, the first thing he suggested was that they integrate the music with the story, which at that time in Hollywood they usually didn’t do. They’d stop the story, and you’d sing a song. They’d stop the story and sing a song. That you integrate this — Arthur Freed accepted the idea immediately. Yip then wrote — Yip and Harold then wrote the songs for the 45 minutes within a 110-minute film. The munchkin sequence and into the Emerald City and on their way to the wicked witch, when all the songs stopped, because they wouldn’t let them do anymore. OK? You’ll notice then the chase begins, you see, in the movie.

AMY GOODMAN: Why wouldn’t they let them do anymore?

ERNIE HARBURG: Because they didn’t understand what he was doing, and they wanted a chase in there. So, anyhow, Yip also wrote all the dialogue in that time and the setup to the songs, and he also wrote the part where they give out the heart, the brains and the nerve, because he was the final script editor. And there was eleven screenwriters on that. And he pulled the whole thing together, wrote his own lines and gave the thing a coherence and a unity, which made it a work of art. But he doesn’t get credit for that. He gets “lyrics by E.Y. Harburg,” you see? But, nevertheless, he put his influence on the thing.

AMY GOODMAN: Who wrote The Wizard of Oz originally, the story?

ERNIE HARBURG: Yeah, Frank L. Baum was an interesting kind of maverick guy, who at one point in his life was an editor of a paper in South Dakota. And this was at the time of the populist revolutions or revolts, or whatever you want to call it, in the Midwest, because the railroads and the Eastern city banks absolutely dominated the life of the farmers, and they couldn’t get away from the debts that were accumulated from these. And Baum set out consciously to create an American fable so that the American kids didn’t have to read those German Grimm fairy stories, where they chopped off hands and things like that. You know, he didn’t like that. He wanted an American fable.

But it had this underlay of political symbolism to it that the farmer — the scarecrow was the farmer. He thought he was dumb, but he really wasn’t; he had a brain. And the tin woodman was the result — was the laborer in the factories. With one accident after another, he was totally reduced to a tin man with no heart, all right, on an assembly line. And the cowardly lion was William Jennings Bryan, who kept trying — was a big politician at that time, promising to make the world over with the gold standard, you know? And the wizard, who was a humbug type, was the Wall Street finances, and the wicked witch was probably the railroads, but I’m not sure. All right?

So it was a beautiful match-up here with Frank Baum and Yip Harburg, OK, because in the book, the word “rainbow” was never once mentioned. And you can go back and look at it. I did three times. The word “rainbow” is never once mentioned in the book. And the book opens up with Dorothy on a black-and-white world, that Kansas had no color. Just read the first paragraph in it.

So, when they got to the part where they had to get the song for the little girl, they hadn’t written it yet. They had written everything else. They hadn’t written the song for Judy Garland, who was a discovery by one of Yip’s collaborators, Burton Lane. And nobody knew the wonder in her voice at that time. So they worked on this song, and at that time, Ira, Yip, Larry Hart and the others thought that the composer should create the music first. Now, they were both locked into — the lyricist and the composer were locked into the storyline and the character and the plot development. So they both knew that at this point there was a little girl in trouble on the Kansas City environment, all right, and that she yearned to get out of trouble, all right? So Yip gave Harold what they call a “dummy title.” It’s not the final title, but it’s something that more or less zeroes in on what the situation is all about and what — this little girl is going to take a journey, all right? So Yip gave him a title: “I Want to Get on the Other Side of the Rainbow.”

YIP HARBURG: Now, here’s what happened, and I want you to play this symphonically! OK, I said, “My god, Harold! This is a 12-year-old girl wanting to be somewhere over the rainbow. It isn’t Nelson Eddy!” And I got frightened, and I said, “I don’t — let’s save it. Let’s save it for something else. But don’t — let’s not have it in.” Well, he felt — he was crestfallen, as he should be. And I said, “Let’s try again.” Well, he tried for another week, tried all kinds of things, but he kept coming back to it, as he should have. And he came back, and I was worried about it, and I called Ira Gershwin over, my friend. Ira said to him, he said, “Can you play it a little more in a pop style?” And I played it, with rhythm.

OK, I said, “Oh, well, that’s great. That’s fine.” I said, “Now we have to get a title for it.” I didn’t know what the title was going to be. And when he had [sings] dee-da-dee-da-da-da-da, [talking] I finally came to the thing, the way our logic lies in it, “I want to be somewhere on the other side of the rainbow.” And I began trying to fit it: “On the other side of the rainbow.” When he had a front phrase like daa-da-da-da-da — now, if you say “eee,” you couldn’t sing “eee-ee.” You had to sing “ooooh.” That’s the only thing that would get a — and I had to get something with “oh” in it, see: “Over the rain” — now, that sings beautifully, see. So the sound forced me into the word “over,” which was much better than “on the other side.”

JUDY GARLAND: [singing] Somewhere over the rainbow
Way up high,
There’s a land that I heard of
Once in a lullaby.

ERNIE HARBURG: Anyhow, Yip — Arlen worked on it. He came up with this incredible music, which, if anybody wants to try it, just play the chords alone, not the melody, and you will hear Pachelbel, and you will hear religious hymns, and you will hear fairy tales and lullabies, just in the chords. No one ever listens to that, but try it, if you play the piano.

And at any rate, on top of these chords, then Harold started the thing off with an octave jump: “Somewhere” — OK, and Yip had no idea what to do with that octave jump. Incidentally, Harold did this in Paper Moon, too, if you remember. Let’s see how did that start?

YIP HARBURG: [singing] It’s only a paper moon
Sailing over a cardboard sea
But it wouldn’t be make-believe
If you believed in me

ERNIE HARBURG: And Harold was a great composer. So Yip wrestled with it for about three weeks, and finally he came up with the word. You see, this is what a lyricist does: the word, to hit the storyline, the character, the music. It’s an incredible thing. “Some-where.” All right, and then when you put in an octave, you get “some-where,” OK, and you jump up, and you’re ready to take that journey. All right? Where? “O-ver the rainbow.” OK? And then you’re off!

It’s not a love song. It’s a story of a little girl that wants to get out. She’s in trouble, and she wants to get somewhere. Well, the rainbow was the only color that she’d see in Kansas. She wants to get over the rainbow. But then, Yip put in something which makes it a Yip song. He said, “And the dreams you dare to dream really do come true.” You see? And that word “dare” lands on the note, and it’s a perfect thing, and it’s been generating courage for people for years afterwards, you know?

JUDY GARLAND: [singing] Somewhere over the rainbow
Skies are blue,
And the dreams that you dare to dream
Really do come true.

ERNIE HARBURG: That’s the way that the whole score came.

AMY GOODMAN: Was it a hit right away?

ERNIE HARBURG: No, it wasn’t. This was supposed to be an answer, MGM’s answer to Snow White and the Seven Dwarves, and of about 10 major critics at that time when The Wizard of Oz came out, I would say only two liked the show. The other eight said it was corny, that it was heavy, that Judy Garland was no good, and so forth. Oh, yeah. You could read again in the book, Who Put the Rainbow on The Wizard of Oz?, by Harold Meyerson and Ernie Harburg. But it persisted, you know? And then, in 1956, when television first started saturating the nation —

AMY GOODMAN: More than 20 years later.

ERNIE HARBURG: More than 20 years later. I don’t think they even had their money back from the show, see? MGM sold the film rights to CBS, who then put it on. And it hit the top of the — it broke out every single record there was, and it’s been playing every year since then. And, of course, it went around the world, and it’s become a major artwork, which is, I must say, an American artwork, because the story, the plot with the three characters, the brain, the heart, the courage, and finding a home is a universal story for everybody. And that’s an American kind of a story, all right? And Yip and Harold put these things into song.

AMY GOODMAN: Who did the munchkins represent?

MUNCHKINS: [singing] We represent the Lollipop Guild
The Lollipop Guild, the Lollipop Guild.
And in the name of the Lollipop Guild…

ERNIE HARBURG: Oh, you mean political thing? I think they represent the little people, you know, the people. And that’s they way they were — it came on in the book. You see, the book, if you’re a purist, you wouldn’t like the film. It’s just like anything else. There are societies of people who meet and discuss the books. OK, there’s even a society for the winkies, which are the guards around the wicked witch’s, you know, castle. There really is! They meet once a year. And they’re serious! They don’t like the picture, because it didn’t follow the book, see, because Yip and the writers changed it, as Hollywood will.

AMY GOODMAN: Was the book a little bit more favorable to the winkies?

ERNIE HARBURG: No — well, yes! The winkies were good people, and they were played up there. If you go back and read the book, you will see that they were a lovely, decent kind of people, yes. That was one thing. I guess it wasn’t PC there, you know?

But, nevertheless, when you read a good novel, and you see the film, there’s hardly any relationship between the two. All these lines from the film have entered the American language in a way that people don’t even know where they came from. You know, “Gee, Toto, looks like we’re not in Kansas anymore.” Or, you know, “Come out, come out, wherever you are,” which in the ’70s started taking on, when the gay movement started, this line started meaning different things, you see?

GLINDA: [singing] Come out, come out, wherever you are
And meet the young lady, who fell from a star.

ERNIE HARBURG: So the songs keep growing with the times. People interpret them, you know?

AMY GOODMAN: How did Yip feel in the late 1950s, when it was a hit, when people started hearing it all over the world?

ERNIE HARBURG: Well, I think they were quite surprised, along with the film moguls, you know, and the fact that — years and years later, he and Harold both said that they did not know what depth and strength that that song “Over the Rainbow” had. And also, one other one, the song “Ding! Dong! The Witch Is Dead” is a universal liberation, a freedom, a cry for freedom, you know, which isn’t seen like that, but it — one time, when some tyrannical owner of an airlines company stepped down, all the employees started singing “Ding! Dong! The Witch Is Dead.”

So people use these words. And during the war, World War II, “We’re Off to See the Wizard” was sung by troops marching, you know? But nobody knows that Yip wrote the words, you see. Now, Harold wrote the music, and the songs were Yip and Harold. That’s it.


AMY GOODMAN: Ernie Harburg, son of the blacklisted lyricist Yip Harburg. This is Democracy Now!

[break]

AMY GOODMAN: This is Democracy Now!, democracynow.org, The War and Peace Report. I’m Amy Goodman, as we continue on our tour through the life of lyricist Yip Harburg with his son Ernie Harburg. Yip Harburg wrote the lyrics to The Wizard of Oz, the movie that inspired the hit Broadway musical and now Hollywood blockbuster Wicked.
ERNIE HARBURG: We’re walking through the gallery here at the Lincoln Center for the Performing Arts, which has “The Necessity of Rainbows,” dedicated to the works of Yip Harburg, the lyricist. And we’re now looking at the various exhibitions.

And while we’re looking for Finian’s Rainbow, I want to tell you that in 1944, Yip conceived and co-wrote the script and put on a show called Bloomer Girl, which was way ahead of its time, because Bloomer Girl was Dolly Bloomer, who was an actual suffragette in 1860 who stood up and invented pants. And it was radical in those days. And the show was about Dolly Bloomer, and she ran an underground railroad, bringing slaves up, and she had an underground paper, and she was an incredible woman. And this was a political show. Some great songs in there. Maureen McGovern does “Right as the Rain” in a great way. Lena Horne does “Eagle and Me,” which was the first song on Broadway that wasn’t a blues lamentation about the black-white situation. It was a call to action. “We gotta be free, the eagle and me.” OK? And Dooley Wilson, who was in Casablanca, sang that.

So, again, Yip managed to get his philosophy into his show, which was the second truly integrated American musical after Oklahoma. And while, you know, it hasn’t been played around, it’s still marked that historically. After that came Finian’s Rainbow.

AMY GOODMAN: You mean Blacks and whites playing in the cast.

ERNIE HARBURG: No, not in there. In Finian’s Rainbow, I mean that it was a political statement. Bloomer Girl was a political statement, and it was a smash hit. In 1946, Yip conceived the idea, the story, the script for Finian’s Rainbow, which was meant to be an antiracist and, in a certain sense, anti-capitalist show also.

AMY GOODMAN: Let’s find it.

ERNIE HARBURG: All right, let’s go.

AMY GOODMAN: Let’s find Finian’s Rainbow.

ERNIE HARBURG: Here’s Cabin in the Sky, which is the first all-Black Hollywood film in the '40s, which Yip and Harold did also. “Happiness Is Just a Thing Called Joe.” Here's Bloomer Girl that I’m talking about. So, we should be, somehow, coming onto Finian’s Rainbow. But here’s Yip here. There’s a video of Yip talking, if you want to meet the man.

INTERVIEWER: You got into political trouble in this country at a time when a lot of people got into political trouble, during the McCarthy years. Were you blacklisted?

YIP HARBURG: Thank God, yes.

INTERVIEWER: During that McCarthy period, were they actually going through your lyrics with a fine-toothed comb looking for lines that might be subversive, that might show Yip Harburg’s true political colors?

YIP HARBURG: Yes. I wrote a song for Cabin in the Sky, which Ethel Waters sang and was part of the situation in the picture. Here was a poor woman who had nothing in life except this one man, Joe, and she sang, “It seemed like happiness is just a thing called Joe.”

One of the producers, with not a macroscope, but a microscope, found in this lyric that “Happiness Is Just a Thing Called Joe” was a tribute to Joe Stalin. We’re kidding about it now, but the country, this was the blackest, the blackest and darkest moment in the history of this beautiful country.

ERNIE HARBURG: Now, here we are at Finian’s Rainbow at last. And this was — Yip conceived this in 1946. And Fred Saidy, who was his co-script writer — and Harold Arlen demurred from writing this, because he felt that Yip was too fervent in his political opinions, and he wanted — Harold wanted to do something else. So Yip got Burt Lane and then came out with this great, great score from Finian’s Rainbow, “Old Devil Moon.”

“How Are Things in Glocca Morra?” etc. But the theme of Finian’s was a total fantasy, and it was an American fable in which an Irishman and his daughter come from Ireland, search around and find Rainbow Valley in “Missitucky.” OK? And he believes that if he plants the crock of gold, which he stole from the leprechaun, in the ground, that it will grow, just like at Fort Knox, right? The whole thing was fabulous!

And then, the Southern white senator, a very stereotypic part, finds out that Finian has this land, and tries to run him out of town, because there’s Blacks and whites living together, and, you know, they’re sharecroppers. And they claim that Finian’s daughter is a witch, and they’re going to burn her at the stake, and all sorts of incredible things that say something about the American scene.

But the score was so great that people who see it do not see it as a socialist tract, which the only one on Broadway; they see it as a very, very entertaining musical and unique in American musicals, because, in the first place, there are very, very few musicals which are original. Most musicals are adapted from books, and this was just conceived by Fred Saidy and Yip as a satiric send-off on American society. So, you’ve got this great song in here, “When the Idle Poor Become the Idle Rich,” how are you going to know who is who or who is which? OK, you know, like that.

And so, Finian’s Rainbow has become a classic. Now, it’s interesting that Finian’s has not had a tour, a national tour, since 1948. But they play it in every single high school in the United States, three or four times a month in every state of the union.

So, Finian’s was, at the time, 1947, when the Cold War was beginning and the House Un-American Committee was starting up, and they were searching for lefties. And by 1951, Yip had been blacklisted from any chance to do any of the wonderful shows that they did in Hollywood, Dr. Doolittle, Treasure Island. He was blocked from working there. And then he was blocked from going into radio and into TV.

So — and this is an historical fact which Yip himself says — Broadway and the American theater in New York City was the only place where an artist could stand up and say whatever he wanted, provided he got the money to put the show on. So, for Finian’s Rainbow, they had to have 25 auditions, because they said it was a commie red thing. And finally, they got the money up, and they put the show up. But by that time, Yip was blacklisted.

And his next show was Jamaica with Lena Horne, with an all-Black cast. One other thing, in terms of Yip’s drive for racial and ethnic equality, and that is that Finian’s Rainbow in 1947 was the first show on Broadway where the chorus line consisted of Blacks and whites who danced with each other, and the chorus was an integrated affair.

AMY GOODMAN: What happened to him during the McCarthy era?

ERNIE HARBURG: Well, he could not work on any major film that they wanted him to work on from the major studios in Hollywood. The setup was that Roy Brewer, who was the head of the IATSE union — I’m sorry to say that — was the one who —

AMY GOODMAN: What do you mean?

ERNIE HARBURG: Well, I mean this is a stagehands’ union. I’d like to say good things about unions, but they get bureaucratized, and they go right-wing, you know? They get bad. This was a bad leader, and he terrorized all of the Jewish moguls who were being accused of communism by the House Un-American Activities Committee, and they yielded to whatever he said to them, out of fear that they would get branded as communists or that they’d boycott the film, all right?

And so, when, you know, they called Yip in to do Huckleberry Finn with Burt Lane, then Roy and the guys said, “No, he’s on our blacklist, OK? And you can’t hire him.” And then Yip went away. And they wanted him to work on Dr. Doolittle. “No, you can’t hire him.” And the same thing for radio and TV. And that was known as a, quote, “blacklist,” which wasn’t — that wasn’t the first use of the term, because in small towns we had company corporations going, if you did something that the company didn’t like, you were blacklisted from town. You couldn’t get a job in town. But this was the first time, due to the technology, that a blacklist was national and accompanied by a loaded word, “communist,” that could get you fired anyplace.

For Yip, it was horrible, because his friends, who were artists, suddenly had no income. And there were suicides. There was divorces. There were people who left the country. There were people whose lives were just ruined. And so, Yip supported some of them. Dalton Trumbo, who was one of the Hollywood Ten who were first picked out by the House Un-American Activities Committee to go to jail for a year, a citation. “Are you now or have you ever been a member of the Communist Party?” You know, Yip fronted him with money, and so forth. It was a horrible time.

AMY GOODMAN: How long couldn’t Yip work for?

ERNIE HARBURG: For about from 1951 to 1962. He came back to Hollywood in 1962, when he and Harold Arlen did Gay Purr-ee, which is with Judy Garland. She asked them to come back. And it’s a cult animated cartoon now, which you can get in your video. And I remember him putting on a show at the Taber Auditorium. “Welcome Back, Yip,” you know? And he — in ’62.

AMY GOODMAN: But that means that The Wizard of Oz made it big during the time that he was blacklisted. That was — and when you consider the social commentary that it was making, that’s pretty profound.

ERNIE HARBURG: Yeah, but I don’t think hardly anyone knows the political symbolism underneath The Wizard of Oz, because, again, it’s a thing that happens in Finian’s Rainbow, even though as Peter Stone, a noted playwright on Broadway, said, “It’s the only socialist tract ever on Broadway,” all right? People don’t hear the political message in it, OK? They are vastly entertained. The same thing happens with The Wizard. You know, nobody would even think of such a thing.

YIP HARBURG: My songs, like “When the Idle Poor Become the Idle Rich” and “Brother, Can You Spare a Dime?” caused a great deal of furor during a period in Hollywood when a fellow by the name of Joe McCarthy was reigning supreme. And so, they got something up for people to take care of us, like me, called the blacklist. And I landed on the enemy list.

And in order to overcome the enemy list — what was the enemy list? Well, it’s, one, that you were a red; another one, that you were a bluenose; and the other one, that you’re on the blacklist. Finally, I thought the rainbow was a wonderful symbol of all these lists. In order to overcome the enemy list and this rainbow that they gave me the idea for, I wrote this little poem:

Lives of great men all remind us
Greatness takes no easy way,
All the heroes of tomorrow
Are the heretics of today.
Socrates and Galileo,
John Brown, Thoreau, Christ and Debs
Heard the night cry “Down with traitors!”
And the dawn shout “Up the rebs!”
Nothing ever seems to bust them —
Gallows, crosses, prison bars;
Tho’ we try to readjust them
There they are among the stars.
Lives of great men all remind us
We can write our names on high
and departing leave behind us
Thumbprints in the FBI.

Appreciating Forests


December 27, 2024
Facebook

I walk almost daily up into the Santa Fe National Forest along with neighbors and our dogs, and I am always reminded how fortunate we are to have a relatively natural and beautiful forest just outside of Santa Fe. All the forests of the Southwest and across the West are critically important to the planet, and reconnect us with the natural order in an increasingly chaotic world.

Last March, The Forest Advocate invited whoever felt so moved to write several sentences expressing why our forests are so important, and to simply appreciate them. It’s helpful to remind ourselves why conserving our forests is essential – for us and for the generations to come. And that the natural world has deep intrinsic value apart from human needs and desires.

Below are reflections on forests from some friends and readers of The Forest Advocate:

For me, the forests, any forests, represent a shrine of the sacred. The intelligence of nature and its complex ecosystem of animals, plants and minerals, like any reverent edifice, can provide calm to my mind, exercise to my body and soothing to my soul.

Our scientific knowledge of the harmonious workings of a forest continue to give us information about our Mother Earth. But for me, the direct experience of the forest, without any thought of carbon sequestration, oxygen production, cooling the earth’s surface or any other amazing gift, leaves me with a sense of awe and wonder as only a natural forest can.

The protection of our forests is all the more important with climate changes and our need for refugia increases.

– Dee Blanco, DVM

I have lived on the same property on the Old Santa Fe Trail since 1981, and before I began digging the foundations for my house in 1982, I noticed a small ponderosa tree which was only about 5 feet tall and two inches in diameter, about twelve or fifteen feet down-slope from the proposed north wall. I resolved to take care not to damage that tree during the construction, and today, about forty three years later, that tree is thriving and now is about 50 feet tall with a diameter at the base of over 20″. So I can truly say that this tree is a friend and I feel a connection to it that seems to me to be mutual. Certainly the tree has been aware of and has appreciated my love and care in the form of the regular watering I have done, especially over the last decade as the amount of rainfall and snow we get has diminished.

– David Birnbaum

Many years ago, I used to hike down a trail in Colorado that had an enormous tree that looked like it was straight out of a Harry Potter movie. It had a hole in the middle, and I always felt the magic in this tree every time I passed it. It emitted mystical energy that was palpable in my energy field. I always thanked it, feeling grateful for its presence. So, for me, trees are more than vegetation that holds the earth together with their strong roots. They are more than beautiful images that blow in the wind, gather snow on their branches and offer homes to the birds. They are spiritual beings in their own right, deserving of all the respect and gratitude we can bestow upon them.

– Ellen Kohn

Even as a child, I knew that I felt different, felt better, being in a forest. And camping in a forest, near a stream, well, that was the best. Tall pine trees somehow reminded me that I didn’t need to prove my worth to be loved. I just needed to be. After all, there they were, the trees, just being themselves, tall and glorious, waiting for me to notice.

– Dana Reilly

Trees are our partners in the climate emergency: they sequester carbon, promote rain, and network to sustain the health of the ecosystems. Trees figure in human symbolism from our beginnings because they ARE “life”; we breathe in what they breathe out. May this reciprocity continue ~ lest we perish.

– Maj-Britt Eagle

As humans, we often regard our forests only as natural resources for us to use to sustain our lives. Yes, our forests are the “lungs” of the planet. And, beyond that, as we act as stewards of our natural world, we learn to be in awe of the wisdom of our forests. The ecological foundations of our forests are there to inform humans of intrinsic values within the balance of nature.

Acting in community as stewards, we act together to partner with nature – to emulate nature’s balances and thus deepen our experiences of co-existing peacefully with nature and each other.

– Lura Brookins

A forest
A home and place
A shade for my bones, ancestral ashes
Beauty for soul and water for spirit
Solace for tears, joy for the ears
Owl hoots for a mate, I call back with my flute
Forest feeds microbes and tall-standing, ponderous pines
Filters water to make clean drinking, air for supple breaths.
Forest stands for life
Forest houses my kin, soothes my skin
A forest
A home and place

– Charly Drobeck

Forests are vital for sustaining life on our planet, as they provide habitat for countless species, purify our air, and regulate our climate. Without them, we lose the protective green lungs that keep our world healthy. I invest my time in protecting forests because their well-being ensures a livable future for all, including generations yet to come.

– Douglas Moore, The Forest Advocate admin

The forest, for me, is more than a tree-covered landscape; it is a life-sustaining force and a spiritual sanctuary. It draws clouds to the mountains, beckons rain by seeding droplets with terpenes, filters and safeguards water, breathes oxygen into the air, and sustains life through countless intricate pathways. It also holds my memories.

In Santa Fe’s forests, I scattered the ashes of my beloved Australian Shepherd, Lauper, in the 1990s. Decades later, in 2019, my Norwegian Forest Cat, Mauser, was laid to rest here as well. It is here that I discovered two of my greatest passions: skiing and observing fungi. These woods shelter moments of joy, sorrow, and personal growth—echoes of a lifetime intertwined with their roots.

– Joey Smallwood, MS Environmental Science and Policy, GIS

Natural forests cleanse the air we breathe and the water we drink, remind us of the wild things in nature, and bring sanity in a sea of humanity.

– Dr. Dominick DellaSala, Chief Scientist at Wild Heritage, John Muir Project

Forests need protection from logging, aggressive cutting, over-burning, grazing, wildlife trapping, unnecessary forest roads, off-road vehicles, and many other human impacts. Forest management must be a holistic effort to support forests’ own intelligence as they transform in a warming climate. It takes all of us. Please support conservation organizations that are working to steward our forests and helping to create a new paradigm that honors forests. And please go out into forests to enjoy and appreciate them.

THE AGE OF DR. JOHN DEE

Mysterious graffiti left by Tower of London inmate 500 years ago is solved for first time


Lucia Botfield
Published December 3, 2024 
Nowadays, the historic building is a popular tourist attraction (Picture: GC Images)

Graffiti scrawled on the walls of the Tower of London dating back centuries have finally been deciphered for the first time – including the magical ramblings of ‘sorcerers’

Hundreds of texts etched onto the walls of the historical building that once housed prisoners incarcerated for the most heinous of crimes have been studied by a group of historians researching the significant collections.

Lead researcher, Dr Jamie Ingram, is heading the ‘exciting’ major project, and began studying the Salt Tower on the south-eastern corner, which is part of the curtain wall built by Henry III in the 1230s.

The Salt Tower once imprisoned Hew Draper, who was an innkeeper from Bristol accused of practising sorcery.

Draper was housed in the tower in 1561, and carved an astrological sphere with zodiacal signs in his cell, despite claiming to have destroyed his magic books, The Guardian reports.


‘There were supposed to be 79 examples of graffiti there, according to the historic survey,’ Ingram told the Observer.

‘By the end of the survey that I conducted, there are 354.


‘Very fine viewing of the surface of the walls has allowed us to identify what else is there … acknowledging that every mark is important, rather than just those that have been left by the famous prisoners.’

There are hundreds of inscriptions (Picture: Historic Royal Palaces)

The high profile fortress also held infamous prisoners such as the two princes, Edward V and Richard Duke of York, Anne Boleyn, her daughter Princess Elizabeth, and Guy Fawkes.

The research team are using technology such as raking light, laser scanning and X-ray analysis to decipher the inscriptions, which have never been used at the Tower before.

One of the passages seems to have been written by a woman, which is a groundbreaking revelation in their research.

Ingram said the note referred to a ‘husband’, as well as honours and rivers.

‘We haven’t got any specific records of female prisoners in that tower. This is possibly a woman’s voice, which is incredibly rare in the graffiti, and the first example we’ve got in the Salt Tower itself.

‘We know that there were women at the tower.

‘They’re just not represented in these physical first-person records.

‘This is a rare primary record of a woman’s presence, whether she’s a prisoner herself or the wife of the prisoner.’

SPACE
British space companies invited to join race to build Europe’s new rocket

Sarah Knapton

The European Space Agency has vowed to develop a SpaceX-style rocket to help it catch up with the United States, with the help of British companies.

The ESA is suffering a major launch crisis after it retired its Ariane 5 heavy-load rocket in July only to experience multiple problems with its replacements, which has forced the agency to hitch a ride with SpaceX.

At the UK Space Conference in Belfast, Josef Aschbacher, the ESA director general, said the crisis had forced the agency into a “paradigm shift”’ in which they will launch a competition for new rockets capable of rivalling SpaceX’s Falcon 9 and Starship.


“Launchers are a risky business, they are literally rocket science and sometimes fail, but we have to regain guaranteed access to space,” he said. “We have decided, collectively, on a paradigm shift that means for the next launcher, we will run a competition and the best company will win.

“This is a completely new way of doing it in Europe but it was done already in the US by Nasa, out of which, as we all know, SpaceX with Falcon 9 emerged. We’re doing more or less the same.

“These will be small launches, at the beginning, with a few hundred kilos of payload. They will go into a tonne, maybe two tonnes and eventually five to 10 tonnes for the heavy launcher category.”


The European Space Agency wants to stop hitching a lift on private rockets like Elon Musk's Starship - JOE SKIPPER/REUTERS

Nasa is increasingly outsourcing its launch capability to Elon Musk’s SpaceX and the company is scheduled to take astronauts back to the Moon as part of Nasa’s Artemis III mission, which could launch as early as 2025.

However, SpaceX has suffered a number of mishaps in recent months, with its giant Starship spacecraft exploding twice during test-flights, leading to fears the Artemis III mission may need to be pushed back.

Mr Aschbacher said companies across Europe would be invited to develop the new rocket system for the ESA which is likely to include several companies, such as Skyrora, who are already developing launchers in Britain.

“I see the future of launches in Europe being very much more diverse,” he added. “The UK already has a few launchers that are ready to fly or getting ready to fly.
Huge challenge

“Yes, it’s a huge challenge, some people may say it’s impossible to catch up. It will take time but this is exactly the way Falcon 9 developed, and eventually Starship, and I think we can learn a lot. I’m pretty hopeful that we can catch up in the launcher sector.”

The ESA said it was vital to regain consistent access to space but as well as delays with the Ariane 6 rocket, Europe’s Vega C rocket has been grounded since last December, and European astronauts can no longer fly on the Russian Soyuz after relations broke down with Roscosmos over the Ukraine War.

It has left the ESA relying entirely on SpaceX, although Mr Ashbacher said there was now “light at the end of the tunnel” for Ariane 6. Final tests of the rocket’s Vulcain engines are due to take place this week and, if successful, a date for its maiden test flight will be announced soon after.

Laser Beam Message Traveled 10 Million Miles Across Space to Earth

Cassidy Ward
Tue, November 21, 2023 

Lasers are a staple of the science fiction genre, generally used in various seemingly magical technologies or as weapons. Lasers pld a significant role in the sci-fi classic Farscape (streaming now on Peacock) by way of handheld energy blasters and larger space-based light weaponry. Here in the real world, scientists just struck California with one of the most impressive space lasers in history, and it could revolutionize the way we communicate with craft and crew in space.

Earth Receives a Distant Laser Message from 10 Million Miles Away

NASA’s Deep Space Optical Communications (DSOC) experiment hitched a ride aboard the Psyche spacecraft, headed toward the large metallic asteroid of the same name. The experiment is made up of instruments capable of sending and receiving infrared laser light across incredible distances.

RELATED: What to Know and How to Watch NASA’s Launch to the Asteroid Psyche

The experiment is planned to last two years, sending and receiving laser signals from increasingly distant locations on its way to its final destination. By the end, it will (hopefully) be able to communicate cleanly from the asteroid belt between Mars and Jupiter.

Of course, we’ve sent and received signals from much farther distances before and we’re still doing it all the time. We have spacecraft happily whizzing around Jupiter and sending back information, not to mention the Voyager spacecraft, still eking out a living in interstellar space. But optical communication would offer significantly higher bandwidth. The goal is to build space-based communications systems with between 10 and 100 times the bandwidth of conventional radio-based communication. That’s because near-infrared lasers have tighter waves than radio, allowing more information to travel in a smaller package.

While the mission is still in its early stages, the team behind it recently achieved a milestone when they gathered first light from the experiment on November 14. From a distance of about 10 million miles (16 million kilometers), about ten times the distance to the Moon, DSOC locked onto an uplink laser beacon transmitting from JPL’s Optical Communications Telescope Laboratory near Wrightwood, California. Using that beacon, the DSOC adjusted its angle to point back at the Hale Telescope at the Palomar Observatory in California. The successful back and forth between Earth and the DSOC marks the most distant demonstration of optical communication in history.
The Future of Laser Communication in Space

“Achieving first light is one of many critical DSOC milestones in the coming months, paving the way toward higher-data-rate communications capable of sending scientific information, high-definition imagery, and streaming video in support of humanity’s next giant leap: sending humans to Mars,” said Trudy Kortes, director of Technology Demonstrations at NASA Headquarters in Washington, in a statement.

Photo: NASA/JPL-Caltech/Palomar Observatory

The instrument works by sending bits of data encoded in individual photons of laser light. Once those photons are received at the Hale Telescope, the data can be extracted from the photons and transformed back into ones and zeroes. As the Psyche spacecraft and the DSOC experiment travel farther away, scientists are working to refine the systems and control pointing the downlink laser. The farther it is, the more difficult it is to hit the receiving telescope with the laser beam, but it’s even more complicated than that.

RELATED: Everything You Need to Know About NASA's "Asteroid Autumn"

The technology also needs to take time and motion into account. When it gets to its final destination in the asteroid belt, the light travel time will be about 20 minutes, that’s plenty of time for both the spacecraft and the Earth to have moved. Any light beams being sent between the two will need to compensate for that movement. The DSOC needs to point not to where the receiving telescope is, but to where it will be.

A transition to optical systems should lead to a revolution in space-based communication and it might be just about as good as we can do, at least until we find a wormhole and crack FTL communication.

In the meantime, you can watch Farscape streaming now on Peacock. No lightspeed lag.


Earth received a message sent from a deep space laser — it took just 50 seconds to travel 10 million miles

Marianne Guenot
Wed, November 22, 2023 


NASA beamed a message from nearly 10 million miles

The technological feat, using NASA's Psyche probe, broke new ground for deep space communications.

NASA hopes to one day send high-speed streaming to Mars.

NASA has achieved a world-first after sending a laser-beamed message to Earth from nearly 10 million miles away within 50 seconds.

While the space agency has long been able to communicate with spacecraft using radio waves, it had never before been able to send information using lasers from that far into space.

The feat, achieved using NASA's Deep Space Optical Communications (DSOC) experiment on board the Psyche spacecraft, could someday allow humans to stream video calls on Mars.

The system is capable of beaming information 10 to 100 times faster than current space communications equipment, per a press release published Thursday.

Bringing fiber optic tech to Mars

The probe homed into a powerful laser signal sent from the Jet Propulsion Lab's (JPL's) Table Mountain Facility near Wrightwood, California. This acted like a beacon to help Psyche aim its transmitter.

The spacecraft then beamed back information using its laser. The signals were received by the Hale Telescope in San Diego County, California, within around 50 seconds.

The probe was about 10 million miles away at the time (16 million kilometers). That's about 40 times the distance from the Earth to the moon.

"Achieving first light is a tremendous achievement. The ground systems successfully detected the deep space laser photons from DSOC's flight transceiver aboard Psyche," said Abi Biswas, project technologist for DSOC at NASA's Jet Propulsion Laboratory.

"And we were also able to send some data, meaning we were able to exchange 'bits of light' from and to deep space.".

While getting a few bits from space may seem underwhelming, it is a crucial step that could revolutionize deep-space communications.

NASA and other space agencies are vying to bring humans back to the moon within the coming decade, a step toward their grander ambition to colonize Mars.

These explorers will need to be able to communicate with Earth effectively, and DSOC could help with that.

Optical communication is the same technology used in fiber optic internet. The light signal arrives just as fast as radio waves but can communicate a lot more information. This could offer high-bandwidth uploads and downloads.

"The primary objective is to give future NASA missions the tools for returning data at much higher rates," Biswas said in a video.

This first experiment is "paving the way toward higher-data-rate communications capable of sending scientific information, high-definition imagery, and streaming video in support of humanity's next giant leap: sending humans to Mars," said Trudy Kortes, NASA director of Technology Demonstrations for the Space Technology Mission Directorate.

The system required some high-tech engineering, including developing a cryogenically-cooled superconducting detector that could spot a billion photons per second to squeeze every bit of information from the faint light traveling tens of millions of miles to Earth.

A close-up of the detector attached to DSOC's receiving ground station at Palomar.NASA/JPL-Caltech

While the experiment proved the system could work, the team has many challenges ahead.

The technology is designed to work when Mars is as far away from the Earth as possible — that's about 235 million miles, or more than twice the distance between the sun and Earth.

At that distance, the light sent by Psyche will be much fainter. And at that distance, the photons will take about 20 minutes to arrive.

That's enough time for both the spacecraft and Earth to have moved, which means JPL scientists will need to make some careful calibrations to make sure the signal is detected as it arrives.

The team aims to test Psyche's DSOC system again as it whizzes past Mars on its way to its mission target: the asteroid belt between the red planet and Jupiter.

NASA's Psyche spacecraft just fired a laser 10 million miles away in deep space

Illustration of spacecraft with two solar panels with stars and black space in behind.

A NASA laser just fired successfully in a deep-space test.

On Nov. 14, NASA picked up a laser signal fired from an instrument that launched with the Psyche spacecraft, which is currently more than 10 million miles (16 million kilometers) from Earth and heading toward a mysterious metal asteroid. (The spacecraft is at more than 40 times the average distance of Earth's moon, and still voyaging afar.)

The moment marked the first successful test of NASA's Deep Space Optical Communications (DSOC) system, a next-generation comms link that sends information not by radio waves but instead by laser light. It's part of a series of tests NASA is doing to speed up communications in deep space, on different missions.

"Achieving first light is a tremendous achievement. The ground systems successfully detected the deep space laser photons from DSOC," Abi Biswas, the system's project technologist at NASA's Jet Propulsion Laboratory (JPL) in Southern California, said in an agency statement.

"And we were also able to send some data, meaning we were able to exchange 'bits of light' from and to deep space," Biswas added.

Other missions have tried out laser comms in Earth orbit or on the way to the moon and back, but DSOC gives laser communications its trickiest, most distant test yet. If it's successful, NASA officials expect that astronauts of the coming decades, bound for the moon or for Mars, may use laser light as their means of taking with ground control.

This DSOC test began in California, at JPL's Table Mountain Facility. There, in the hills outside Los Angeles, engineers switched on an uplink beacon, a near-infrared laser pointed in Psyche's direction. About 50 seconds later, a transceiver on Psyche received the laser and relayed its own laser signal back to Palomar Observatory, near San Diego.

The Nov. 14 test marked "first light" for DSOC, and engineers will continue to test the system as Psyche voyages to its namesake asteroid, which resides in the asteroid belt between Mars and Jupiter. Psyche should get there in 2029, then spend 29 months surveying the bizarre metallic worl


Object Crashes Into Jupiter, Explodes

See ya!

As Mashable reports, a video captured by an amateur astronomer in Japan shows a super-bright comet, also known as a bolide, exploding as it collides with Jupiter.

A gas giant, Jupiter has a powerful gravitational pull that's caused similar spectacular crashes over the years. This one wasn't even particularly powerful — unlike some previous Jupiterian impacts that humanity has been able to see, there doesn't seem to be any lingering visible damage to the planet's gaseous atmosphere — but it's fascinating to watch nonetheless. The scene has doomed-fly-to-lantern energy, albeit on a cosmic scale.

"There was another impact on Jupiter last night!" noted planetary astronomer Heidi Hammel, who works with NASA's James Webb Space Telescope, wrote in a Nov 16 quote tweet — if we can still call it that — of the original video. "The bright flash is a bolide — a shooting star in the atmosphere of Jupiter."

Bolides like the one seen in the video aren't unique to Jupiter; more commonly known as fireballs, a small handful of the ultra-bright celestial bodies enter Earth's atmosphere every year. They burn out quickly, and often make their way into Earth's atmosphere over expansive oceanic regions, and are therefore hard to catch from the ground.

While this fireball may not have done any real damage to Jupiter, other collisions certainly have. Back in 1994, the gas giant was pelted with pieces of the comet Shoemaker-Levy 9 over the course of several days, an event that according to NASA left "huge, dark scars in the planet's atmosphere and lofting superheated plumes into its stratosphere." And Hammel, who at the time "led visible-light observations of the comet" with NASA's Hubble Space Telescope, counts that impact as a turning point in Earth-asteroid relationships.

"Shoemaker-Levy 9 was a sort of punch in the gut," Hammel recounted of the impact back in 2019. "It really invigorated our understanding of how important it is to monitor our local neighborhood, and to understand what the potential is for impacts on Earth in the future.”

Bolides haven't presented a huge problem for planet Earth, and as NASA's successful DART test showed last year, humankind has made significant progress in our asteroid defense systems. But if this latest bolide is anything, it's a reminder that the final frontier is sometimes a game of brutal cosmic bumper cars.

A new photo from the James Webb Space Telescope of the deep center of the Milky Way highlights never-before-features that have yet to be scientifically explained. Specifically, JWST narrowed in on the region called Sagittarius C (Sgr C), which is about 300 light-years away from Sagittarius A*, the supermassive black hole at the Milky Way’s center. The unprecedented detail casts the region in a new light to astronomers, allowing them to study it in ways that weren't possible before.

Astronomers say the level of resolution is allowing them to see new features for the very first time, like how the galactic center is actually a very crowded place with around 500,000 stars — including a cluster of protostars, which are stars that are still forming. At the heart of this cluster is a previously known massive protostar that is 30 times the mass of our own Sun. JWST’s NIRCam (Near-Infrared Camera) instrument also captured large-scale emission from ionized hydrogen bordering the lower side of an infrared-dark cloud. Astronomers say they are excited to dig in, and hope this new image will lead to unprecedented information on how stars form.

“There’s never been any infrared data on this region with the level of resolution and sensitivity we get with Webb, so we are seeing lots of features here for the first time,” said the observation team’s principal investigator Samuel Crowe, in a media statement. “The image from Webb is stunning, and the science we will get from it is even better.”

SpaceX’s explosive test flight achieved key milestones. But there is still a long way to go

Tue, November 21, 2023 at 2:36 PM MST·11 min read

Mere moments after SpaceX’s Starship system — the most powerful rocket ever built — was lost in a test flight Saturday, a somewhat complicated narrative around the vehicle began to emerge.

The company immediately described the flight as a huge step in the right direction.

“What we did today will provide invaluable data to continue rapidly developing Starship,” SpaceX said Saturday in a statement. “With a test like this, success comes from what we learn, and today’s test will help us improve Starship’s reliability as SpaceX seeks to make life multiplanetary.”

Yet the loss of another Super Heavy rocket booster and Starship spacecraft highlights just how far they have left to go in the development process, even as significant progress is made. It also raises questions about whether SpaceX can meet some key deadlines on the horizon.

Enabling humans to colonize the cosmos is the ultimate goal for this vehicle: SpaceX intends to use it to send people to the moon, Mars and beyond.

Crucially, the Starship spacecraft is also the vehicle that NASA selected to land US astronauts on the moon for the first time in five decades as part of its Artemis program. The space agency is racing against China to get the job done, vying to become the first to develop a permanent lunar outpost and set the precedent for deep-space settlements.

The first lunar mission that would make use of Starship — Artemis III — is slated for late 2025. In the aftermath of the first failed test flight in April, NASA officials expressed concern that the vehicle wouldn’t be ready in time.

But federal officials reacted favorably to Saturday’s test launch. NASA Administrator Bill Nelson offered SpaceX his congratulations and noted “test is an opportunity to learn — then fly again.”

And to be clear, Starship is still an essential part of NASA’s moon-landing plan. However, there are numerous daunting technological hurdles left to clear before those lunar ambitions becomes reality.

What SpaceX has left to learn


Several key aspects of the second flight test went to plan: When the rocket took off from the SpaceX Starbase launch site in Boca Chica, Texas, just after 8 a.m. ET, it was able to ignite all 33 of its engines and continue firing them as the Super Heavy booster — which gives the initial burst of power at liftoff — burned through most of its fuel.

The Starship spacecraft was then able to ignite its own engines and break away from the Super Heavy rocket booster to continue the mission. And the launchpad that served as the starting point managed to survive the sheer force of a rocket generating up to 16.7 million pounds of thrust (7,590 tonnes of force).

None of those milestones were met during the vehicle’s inaugural integrated test flight in April.

But other important steps originally slated for Saturday’s mission didn’t happen. The Super Heavy booster experienced a “rapid unscheduled disassembly” — or an unintentional explosion — shortly after Starship separated from it. The mishap prevented SpaceX from testing the maneuvers that will be necessary to land and reuse the launch vehicle.

Similarly, the Starship capsule made it roughly 10 minutes into its flight, reaching an altitude considered to be beyond the edge of space — about 93 miles (150 kilometers) above Earth’s surface — but SpaceX was forced to terminate the mission when ground control lost its signal.

The vehicle did not spend as much time in space as the company had hoped, collecting mere moments of flight data rather than the hour-and-a-half’s worth mapped out for the mission. John Insprucker, principal integration engineer at SpaceX, said during the livestream that the company had to trigger Starship’s self-destruct feature after contact with the vehicle was lost.

That meant SpaceX wasn’t able to test out Starship’s landing technique either.

“The hardest part about this — or the part that will take the longest — is solving for safe (Starship) reentry and landing,” SpaceX CEO Elon Musk acknowledged in October during the International Astronautical Congress in Baku, Azerbaijian.

Starship and orbital refueling


Being able to recover and rapidly reuse both the Starship spacecraft and the Super Heavy booster are essential to SpaceX’s long-term goals. Such capabilities would make the rocket system affordable and nimble enough to rapidly conduct all the launches necessary to get the vehicle to the moon.

In order to reach lunar orbit, Starship must be refueled while it’s parked near Earth. That’s because the massive spacecraft won’t have enough propellant left over to traverse the 238,900-mile (384,472-kilometer) void between our home planet and the moon after the initial launch process.

As of now, SpaceX acknowledges it has to launch more than a dozen Starship tankers to refuel one spacecraft destined for the moon, said Wayne Hale — the chair of the NASA Advisory Council’s Human Exploration and Operations Committee — in a Saturday interview. That’s because of the Starship’s immense size: Just getting the vehicle into space requires it to burn through the majority of its fuel. And while Starship can hold up to 3 million (1,500 metric tons) of propellant, the spacecraft itself is only capable of hauling up to 55,000 pounds (250 metric tons) of extra cargo to orbit, according to data published by SpaceX and the FAA.

“So they’ve got to take that rocket that we saw demonstrated … and be able to fly 12, 15 more times for each lunar landing,” Hale told CNN. “That’s gonna be an impressive feat. They’ve got to learn how to do that … where it’s successful and reliable every time, and they’ve got to do that in a very short period of time.”
Starship and the Artemis timeline

With many milestones left to hit, it’s clear that even if the next Starship test flight is wholly successful, a moon landing will remain on the distant horizon.

Musk previously acknowledged in 2020 that he hopes SpaceX will launch “hundreds of missions” with satellites before attempting a flight with crew. SpaceX also must build and test the versions of Starship that will serve as refueling tankers. A lander must be outfitted with life support equipment. And NASA will require Starship to make an uncrewed test landing on the moon before allowing its astronauts on board.

Still, SpaceX emphasized that explosive failures can be integral to its development process, which embraces fiery mishaps in the early stages of designing a rocket in order to learn how to build a better rocket faster than if the company solely relied on ground tests.

Though SpaceX’s failed test flights garner plenty of critics, it does not mean that the company is moving more slowly or costing more money than if NASA had attempted to develop a lunar lander itself.

All told, NASA will pay SpaceX about $4 billion for two lunar landings. (The company has already invested more than $3 billion in developing its South Texas launch facility and the Starship Super Heavy launch system since 2014, according to an FAA court filing dated May 19.)

NASA Astronaut Christina Hammock Koch speaks during a Washington media gathering on May 18, 2023, as NASA astronauts Victor Glover and Reid Wiseman and CSA (Canadian Space Agency) astronaut Jeremy Hansen look on.

For comparison, the Space Launch System rocket and Orion spacecraft that NASA developed for the Artemis program have together cost more than $44 billion since 2006, according to data aggregated by the nonprofit Planetary Society. That rocket system had its first flight test last year. Under NASA’s current plans, SLS and Orion would transport astronauts from Earth to lunar orbit, while Starship would complete the final leg of the journey, ferrying them from the Orion spacecraft to the moon’s surface.

But Hale noted that SpaceX doesn’t use the same development approach as NASA. The space agency spends years on careful design and rigorous ground testing — all but guaranteeing success on the first flight. In contrast, SpaceX wants to put early prototypes in the air, accepting that they may explode but will likely provide valuable information for future testing.

“This is a different paradigm,” Hale said of Starship development. “The government — when you’re working with the taxpayers’ dollars — you really want to be careful and make sure you succeed.

“Whereas (SpaceX) is a private company,” Hale added. “Yes, they’re doing this work in support of the government, but their methodology is quite different. And I think you could be successful either way. But, this way certainly has its exciting moments.”
Another lunar lander: Starship vs. Blue Moon

Starship can also be compared with Blue Moon, another lunar lander under development by the Jeff Bezos-owned space company Blue Origin. NASA selected Blue Moon as an alternative lunar lander for future Artemis missions.

NASA expects to pay the company $3.4 billion for a single crewed lunar landing — the Artemis V mission currently slated for 2028 — with Blue Origin investing at least that much of its own money.

Lakiesha Hawkins, the deputy to the deputy associate administrator for NASA’s moon to Mars program, said at its advisory council’s Human Exploration and Operations Committee meeting last week that Blue Origin’s lunar lander won’t necessarily be simpler than SpaceX’s behemoth rocket and spacecraft system.

“Both of those providers have their challenges,” Hawkins said, referring to SpaceX’s Starship and Blue Origin’s Blue Moon lunar lander. “And they are equally — from my perspective — complex.”

Blue Origin declined to comment on where Blue Moon stands in the development process.

The companies are taking very different approaches in their moon landing strategies, but experts say both SpaceX and Blue Origin will be distinct from their predecessor in some key ways.

Why NASA isn’t just repeating Apollo

Hale, the committee chair, said it can be difficult for members of the public to wrap their heads around why all of these projects are costing so much development time and money if NASA already knows how to put humans on the moon.

Why not just repeat the same thing NASA did during the Apollo program?

“People ask what was wrong with Apollo,” Hale said during the committee meeting last week. “The thing that was wrong with Apollo was it ended.”

NASA and SpaceX are aiming to develop vehicles that don’t just go to the moon once. Apollo already accomplished the “flags and footprints” missions, Hale noted.

Now, the space agency is looking to develop rockets and spacecraft that can push exploration further. NASA aims to establish a permanent moon base and eventually reach Mars in a cost-effective manner.

The Apollo 11 mission, the first manned lunar mission, launched from the Kennedy Space Center in Florida via the Saturn V launch vehicle on July 16, 1969 and safely returned to Earth on July 24, 1969. Aboard the spacecraft were astronauts Neil A. Armstrong, commander; Michael Collins, command module pilot; and Edwin E. Aldrin Jr., lunar module pilot. -

“When you put those sustainable reusability requirements on the program — and the fact that it’s leading on to go to Mars — you do buy into perhaps a more complicated architecture than just repeating Apollo,” Hale said.

And, even as he acknowledged Starship has a long way to go, he added, “I think they made a big step forward.”
What’s next for Starship

Musk has already said the Super Heavy booster and Starship spacecraft will likely be ready for a third test flight in “3 to 4 weeks,” according to a Sunday post on social media, adding, “There are three ships in final production.”

CNN noted that four Starship spacecraft and at least two Super Heavy boosters are visible from public roadways near SpaceX’s facility in South Texas.

It’s not clear, however, how long it will take SpaceX engineers to review the data gathered during Saturday’s flight and implement the necessary changes. And Musk is known to publicize unmet deadlines.

Also unclear is whether SpaceX will have the necessary regulatory approvals to launch another test flight in just a few weeks. The Federal Aviation Administration, which licenses commercial rocket launches, indicated its intentions to open a standard mishap investigation into Saturday’s test flight. After the first test flight in April, a similar investigation took over four months to complete.

Once the investigation is closed, the federal agency will then likely need to complete a safety review of SpaceX’s plans for a third launch before it will issue another permit. It’s not clear how long that process might take.

The FAA did not respond to a request for comment.

Starship's 33 Engines Created The Mother Of All 'Shock Diamonds'

Shock diamonds from Starship's rocket exhaust

SpaceX’s massive Starship rocket lifted off for its second test flight over the weekend. Among the stunning imagery and video to have emerged from the launch that caught our attention was the sight of its super-heavy rocket booster generating gargantuan "mach diamonds" or "shock diamonds." What’s particularly impressive is how the rocket booster’s 33 Raptor engines combined to create a perfectly formed mach diamond as the stack lifted off the pad.

Given how incredible this example of physics visualized on a grand scale looks in the photos, we thought it was an opportune moment to dig deeper into the science behind them, as well as explain what makes their unique appearance during the recent Starship test launch so intriguing.

The 'Starship' system, comprised of a super-heavy rocket booster and spacecraft, took off from SpaceX’s Starbase facility near Boca Chica Beach in South Texas on November 18. In a significant development for SpaceX, and in comparison to the first Starship test launch in April, the rocket booster was successfully able to separate from the spacecraft. This was before the rocket booster exploded over the Gulf of Mexico at an altitude of 91 miles (148 kilometers). Moreover, contact was lost with the spacecraft after it reached space, with the company having to trigger its self-destruct feature shortly thereafter. Eventually, Space X intends for its Starship system to carry crew and cargo to Earth orbit, the Moon, Mars and beyond.

While mach diamonds are more commonly seen when high-performance jets are in afterburner, Starships’ case is a unique as this phenomena was the culmination of 33 rocket engines firing in unison.

Its super-heavy rocket booster's 33 engines includes 13 in the center and 20 surrounding the perimeter of the booster’s business end. Burning methane with liquid oxygen, the rocket booster is capable of creating a mind-boggling 16.7 million pounds of thrust.

In order to understand how the shock diamonds were produced during the Starship launch, we reached out to Dr. Chris Combs (@DrChrisCombs), the Dee Howard endowed assistant professor of aerodynamics at the University of Texas at San Antonio’s Department of Mechanical Engineering. Dr. Combs began by explaining how mach diamonds are formed in detail:

"Nature is always wanting to bring things back to equilibrium, in a sense, [to] kind of get things back to the way that they were in how they started," he said. "There are a lot of different processes in nature that work that way, and pressure differences is one of those."

"When you have something like a rocket, or a jet engine, that creates these really massive pressure differentials, relative to atmospheric air… physics is going to want to change that, and it's going to want to match those values up somehow. And if the pressure differentials are large enough, the only way that that can happen is with a shock wave or an expansion fan. And so these are compressible flow features, and waves that show up when basically you have a very large imbalance of pressure between two masses of air."

"At sea level, when you have a rocket launch, the exhaust that's coming out of the rocket is lower than atmospheric pressure… [resulting in] very high chamber pressures. But then you actually expand that gas through a converging divergent nozzle, to accelerate it to very high speed, because that gives you thrust. So you're trying to accelerate that exhaust as fast as you can. And when you do that, the energy that was there in terms of pressure, gets… transferred to velocity and momentum. And so you're getting that thrust out, but you're losing pressure in the process. So that gas comes out lower than atmospheric pressure, when it comes out of rocket exhausts. And it's low enough where… the only way that that can be matched to atmospheric pressure is with a shockwave, and so the air gets processed through the shockwave."

"The reason you see a diamond pattern," he indicated, "is because the angle of that shockwave is going to be determined, really just by [the] pressure ratio."

Combs went on to explain why Starships’ 33 Raptor engines were capable of forming single mach diamonds during the launch.

"When you typically see a shock diamond or a mach diamond, it can be from like a jet engine test, or a single rocket nozzle test. [When you] look at those up close… you see the same shock diamond effect on the smaller scale."

"But what was interesting, specifically about this case [the second Starship launch], is you had 33 engines firing together, which you would kind of intuitively think would make for a pretty messy environment. I think close up [this] is probably true, there's some complicated dynamics happening there."

https://twitter.com/DrChrisCombs/status/1726259282427974003?s=20


"[When] you zoom out far enough, and really, what it boils down to is they're [the 33 engines, are] acting like one engine. And so you have a region of low pressure caused by all of these engines working together. And that forms this larger mach diamond structure, sort of in the far field, as you zoom out. So you have all these little mini mach diamonds from each one of those engines that's generated… That is especially unique, because there aren't very many rockets… that tried to function with this many rocket nozzles pack that closely together… the closest comp[arison] being the Soviet N1."

It should be noted that images taken from the launch also show additional diamonds forming a string, which can be seen below. "What you will notice, if you watch a rocket launch, as that rocket goes up in the air… [is] that angle is going to slowly change over time," Combs noted.

"And it's actually going to slowly go basically towards parallel with the rocket body. As the rocket goes up, that atmospheric pressure is going to drop because you're going higher up in altitude. And so that shock angle gets thinner as the rocket goes up until eventually the rocket exhaust is just going straight up and down, and you don't see any type of diamond effect. And that's… what we call a perfectly expanded exhaust. Because… the exhaust pressure is exactly what the ambient pressure is outside."

During our exchange, Combs also urged people to think of the recent test, which has been reported by some outlets as a failure, more holistically.

"I think people get frustrated sometimes when I say it's a long ways away," he noted of Starship. "But you have to understand… this is a relatively immature technology right now, that's going to take years to figure out versus [if] it's never going to work. I don't necessarily think it's never going to work. I think that there are some really big hurdles that those engineers have to overcome. And it's going to take time. So I think people need to kind of level expectations a little bit, but it's definitely an interesting project to follow that's extremely ambitious and high risk."

So there you have it, an in-depth look at the gargantuan shock diamonds and why their merged appearance during Starship’s second test flight is so unique. A special thanks to Dr. Chris Combs for taking the time to provide us with such wonderful insight on this topic.

UPDATE: 11/21, 05:26 P.M. EST—
