BEZOS PENETRATED SPACE

Why does Jeff Bezos’s rocket look like that? An inquiry



Experts weigh in on the ‘anthropomorphic’ design of New Shepard, the Amazon CEO’s Blue Origin rocket

Jeff Bezos’s 11-minute trip aboard a Blue Origin rocket to the edge of space on Tuesday left the world’s richest man feeling “unbelievably good” and his crew “very happy”. But afterwards, as he wondered aloud how fast he could refuel, the rest of the world was left pondering just why the New Shepard rocket had such a distinctive shape.

As social media erupted with innuendo, we contacted a few experts to find out why it looked, in the words of one astrophysicist, so “anthropomorphic”. At one major research institution, the press officer referred us to the gender studies department, but Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics, was able to shed some light on the topic.





New Shepard consists of a mushroom-like crew capsule that flares out over a long shaft, called a booster. The rounded top appears more bulbous than that of many other rockets, but it’s not unique. “There’s a long history of what we call hammerhead rockets,” on which the capsule’s diameter is wider than the booster, said McDowell. “If you’re careful, it actually has perfectly fine aerodynamics.”

Just like the tips of passenger and military jets, capsules come in all different shapes, New Shepard’s interior is designed to “maximize the interior volume” to hold six passengers, said Laura Forczyk, the owner of Astralytical, a space analytics company. It also needs a “big, flat bottom” for stable re-entry, McDowell said.

“They went through a lot of iterations coming up with the perfect shape to give them the most volume, the best windows, and [a design that] wouldn’t kill anyone onboard,” said the astrophysicist Scott Manley in a private video shared with the Guardian. “And this is the shape they came up with, this dome shape.”

As for the booster, engineers work to minimize its mass, making it as small as possible. “It is easier to balance a long and skinny cylinder than it is to balance a thicker, fatter cylinder,” Forczyk said.



These competing concerns can lead to a capsule that is a bit wider than might originally have been envisioned. “It comes down to optimizing two different things and not being able to make them quite match,” McDowell said. He pointed to other examples of rockets with slightly flared tops, including the Atlas V Starliner, expected to launch next week.

Adding to those “anthropomorphic” qualities is a ridge near the top that is “very, very obvious”, Manley said. That’s there to accommodate a “ring-shaped fin” that is fundamental to the re-entry process, counteracting the effects of the fin at the bottom as the booster travels in reverse.





All this adds up to some particularly memorable optics. Was there any subtle aesthetic messaging involved? “I don’t know if I would have made the design this way, but I’m sure it was driven entirely by physics” as well as cost savings, said Forczyk.

Still, “they can’t not have noticed,” McDowell said. “You’ve got to imagine there was a meeting where someone went, ‘Do you really want to fly looking like this?’ But I’m guessing an engineer got up and said, ‘This is what the math says. This is the optimum configuration. So this is what we’re gonna fly.’”


FUNNY IT REMINDS ME OF THE SPACE SHIP FROM FLESH GORDON


Jeff Bezos flies to the edge of space in giant phallus…

The billionaire space race is equal parts vulgar and hilarious.

Last week alleged tax exile Richard Branson put last year’s unfortunate business of asking the government to bail out his companies behind him to blast to the edge of space for a few minutes. He nearly managed to achieve what the Soviets did 60 years ago with less technology than you would find in a modern wristwatch.

Not to be outdone Jeff Bezos has gone full Dr Evil and blasted himself to the edge of space in a giant phallus.



A few people pointed out the gilded age levels of wealth between Bezos and his employees.



Jon Stewart perfectly sends up the whole farce with this hilarious video:



I am sure it is fun messing around with big rockets, but just a suggestion lads. Could you put your skills and money into something useful? Solving global warning? Curing malaria? Giving the developing world proper water and sanitation?

Thankfully Jeff Bezos’s ex-wife McKenzie Scott has a bit more of a social conscience. She has donated $8.5 billion in less than a year to actual worthy causes on this planet.
