‘What happened last night was not funny’ – Liz Truss responds to lettuce prank

The former prime minister was not amused.

Liz Truss has said a banner proclaiming “I crashed the economy” with a picture of a lettuce which appeared behind her during a talk was “not funny” and an attempt to “suppress free speech”.

Speaking at Beccles Public Hall and Theatre to promote her book Ten Years To Save The West, the former prime minister was discussing her support for Donald Trump when the banner unfurled behind her.

Led By Donkeys confirmed the event was genuine, but refused to explain how they pulled the stunt off.

Posting on X, formerly Twitter, Ms Truss wrote: “What happened last night was not funny. Far-left activists disrupted the event, which then had to be stopped for security reasons.

“This is done to intimidate people and suppress free speech. I won’t stand for it.
“Would we see the same reaction if the activists were far-right?”

A statement from Led By Donkeys read: “Liz Truss appears to be a huge supporter of free speech up to the point she encounters it”.

Led By Donkeys co-founder Ben Stewart earlier told the PA news agency that the stunt was “all about Liz Truss aligning herself with Trump and the far right in America”.

Ms Truss lasted only 44 days as leader of the country – she was famously outlasted by a lettuce that was recorded on a live stream, created by the Daily Star, which asked: “Which wet lettuce will last longer?” referring to the then prime minister and an actual lettuce.

Once she had been alerted to the sign behind her, the former prime minister was clearly unhappy and left the stage.

Why eco-protesters are serving more time than rioters

Stephen Armstrong
TORTISE
Thursday 15 August 2024


It’s the law, and the law turns out to be political.


About 40 people have been sentenced so far in connection with the UK riots at the start of August. Sentences range from two months for criminal damage to three years for violent disorder. By contrast, five Just Stop Oil protestors were jailed in July for between four and five years for conspiring on a Zoom call to shut down the M25.

So what? If the scales of justice don’t seem fairly balanced, that’s because they aren’t. The discrepancy between relatively light sentences for race rioters and relatively heavy ones for eco-protesters is a function of process – most of the rioters have been swiftly dealt with and pled guilty while the JSO five had a jury trial;
personality – judges are human, after all; and
politics – the history of police and public order acts in the UK is a history of the British state bringing in laws to deal with temporal problems it finds infuriating.

The law. The maximum sentence available to judges for violent disorder, the most severe of the rioters’ offences so far tried, is three years. The maximum sentence for conspiracy to cause a public nuisance is ten years. The rioters are on trial for violent disorder as defined in the Public Order Act 1986. This was created to deal with the Miners’ Strike in 1984. The JSO protesters were on trial for public nuisance as defined by the Police, Crime and Sentencing Act of 2022 and the Public Order Act of 2023. These were created to deal with climate change protests, specifically naming Extinction Rebellion and Just Stop Oil.

Public enemy number one. The first ever UK Public Order Act in 1936 banned political uniforms and required police consent before political marches went ahead. This was created to deal with Oswald Mosely’s British Union of Fascists.

Judge dread. Judge Christopher Hehir, who sentenced the JSO five, noted thatprotesters’ actions had caused people to miss flights, funerals, mock exams, medication, cancer clinic appointments, work and an appearance at the All Party Parliamentary Group for Water;
a police motorcyclist was knocked off his bike; and
the defendants had form in previous protests.

Hehir also dismissed their lack of violence and conscientious motives as non-mitigating.

Harsh, no? During the riots, around 150 police officers were injured and almost half of them hospitalised. Business, hotels and police stations were set alight. Shops were looted. Cars were burned. A number of people were beaten by mobs.

Yes, but. In the case of the rioters, the judiciary has moved with almost unprecedented speed in bringing the cases to court. Currently the average length of time from offence committed to sentencing in the UK is around a year. In Liverpool, rioters were in court and sentenced within a week. It’s a judicial choice at a time when the legal system is under strain, so the judges are either reflecting the state or society’s views.



Soft touch. So far, none of the rioters has been charged with riot under the Public Order Act 1986 which carries a maximum sentence of ten years, although the Director of Public Prosecutions has said that is still a possibility.

Time to fold? Last week Liberty met with the Home Office to discuss dropping the Serious Disruption Regulations 2023, a set of amendments to the Police and Public Order Acts introduced by the former home secretary Suella Braverman that lowered the bar for disruption to be considered criminal.

The amendments were aimed specifically at environmental protesters, and they seem to have pleased Braverman more than the public.The High Court has since ruled them unlawful.
Over the past five years juries have been acquitting environmental protestors who justified their crimes by explaining their beliefs.

The JSO five are appealing against their sentences. The question is whether the legal system can do better than politicians at reflecting the wishes of society.

 

The Riots: A Classic Fascist Mobilisation


By John McDonnell MP

August 14, 2024

To understand why the riots have taken place and how to respond to them, you have to start by looking at who has been involved.

Drawing on other historical examples, it looks like a classic fascist mobilisation. 

At the top are leading demagogues, the political provocateurs, willing to exploit any issue for their political advantage no matter what the consequences for the people or communities involved.

Beneath them are a relatively small phalanx of hardline foot-soldiers, who have been trained and involved in fascist groups like the English Defence League over the years. These are the true-believing fascist muscle behind the riots.

Then there is a larger group: the disgruntled, the dispossessed and the disillusioned. This is the combustible material that the fascists target to set alight: people who are so discontented with their lives – with so little hope, with so little understanding of the real forces that drive our society – that they are prey to the simple, beguiling message that someone else is to blame for how they feel.

All the leaders have to do is point the finger at whichever group is the scapegoat this time round and wait for a spark, an incident, to set the tinder alight. The truth of any incident doesn’t matter. It’s what they can convince people of.

Just as in the 1930s the advent of radio and cinema facilitated the spread of propaganda by the fascists then, so social media has been effectively used in spreading the lies now.

Decade after decade of recent racist and Islamophobic propaganda constructed on centuries-old racism embedded in society makes it so much easier to make race, colour or religion the identifying features of the scapegoat. 

When the fire is lit there are always new joiners, often young people, who can’t resist the excitement or the opportunity to exploit the situation generally with mindless vandalism or looting.

Overcoming the threat of continuing division and violent attacks requires action that is focused on each of these groups.

The demagogues have to be called out and confronted for what they say and what they do. The situation has been exacerbated by mainstream politics; instead of standing up to the far right, many politicians have opportunistically adopted its language and political positioning. 

The lesson is: don’t get into the gutter with them; take them on.

Doing that requires a unity of purpose across progressives in our society. History has taught us that fascism succeeds when the centre and left of politics are divided.

In times of crisis the state has a critical role to play. So it’s not just right that the justice system is used to take out of circulation the demagogues and the foot soldiers of fascism. It is vital to the security of our democracy.

Just as importantly, or even more so, it’s the disgruntled and disillusioned that warrant society’s attention.

It’s interesting how many of the men and women now being prosecuted are breaking down in the dock when they realise the consequences of their actions during the riots.

Many are older without any past convictions. Their sense of anger, whipped up by the demagogues, some mainstream politicians and, of course, by sections of the right-wing media, has left many of them bewildered, facing jail and future lives seemingly beyond repair. 

The election campaign provided the ideal environment for far right politicians to bring the anger to boiling-over point. 

Behind those being prosecuted are many more who didn’t participate in rioting, but who in interview after interview still express, if not sympathy for the rioters, then some appreciation of their motives. 

That’s the challenge society faces.

These riots may have been suppressed, but unless we can come up with a new approach to understanding what allowed the fascists to get a grip on so many in our communities then we will be back here in many years to come.

It doesn’t require high political theory. It does come down to some basic political nous.

Fourteen years of austerity have produced 14 million of our people living in poverty, including four million children, as well as a housing crisis, public services on their knees and a grotesque visible level of inequality generating a sense of unfairness overall.

The low turnout and low percentage level of support for the incoming Labour government should have sounded a warning on just how disillusioned with the political establishment people are. When politics appears to fail them some will turn to rioting and violence. 

People can’t take another wave of austerity and need to see a political movement, maybe beyond political parties, that gives them some hope.

The mobilisation of thousands on our streets has shown what mass action can do to deter the far right. There is a need in the short term for a fresh initiative to continue to discredit and isolate fascists, especially amongst the younger generation, just as the Anti-Nazi League did in the past and Stand up to Racism is doing now, building this grassroots reaction. 

For the longer term we need a movement that can organise in each of our communities to listen to the cares, concerns and, yes, the grievances people have, but this has to be accompanied by cutting through the penetration of the racist and Islamophobic propaganda of the far right and right wing media.

There are well-grounded progressive organisations across our society like the trade union movement, anti-racist campaigns, the women’s movement, anti-poverty campaigns, disability groups and many, many others that could be the foundation stones of such a movement to restore some optimism to us all.

The question for the government is whether they have the political will to provide the powers and resources to make this happen.

Scientists make remarkable discovery about Stonehenge altar origins

The finding upends a century-held belief that the monument's largest Altar Stone came from Wales 

The largest Altar Stone at the heart of Stonehenge is actually from Scotland and not Wales as has been thought for the past century, research has suggested.

Scientists believe the stone at the centre of the megalithic structure in Salisbury Plain, Wiltshire was transported over 435 miles from Scotland – and have described the discovery as “remarkable”.

According to analysis of the altar stone’s chemical composition and mineral crystals, there is a 95 percent chance it comes from north-east Scotland.

It is unclear when the stone arrived at the site, but the team said it may have been placed in the central horseshoe of stones during its second construction phase around 2620 to 2480 BC.

The sandstone at the heart of the ancient site was believed to have come from Wales, as the majority of Stonehenge’s bluestones came from the Preseli Hills area in west Wales and are believed to have been the first stones erected at the site.

The findings suggests Neolithic Britain, an age when human technology was far more limited than today, was a more connected and advanced society than previously thought.

Co-author of the research, Professor Richard Bevins, of Aberystwyth University, said: “These findings are truly remarkable – they overturn what had been thought for the past century.

“It’s thrilling to know that our chemical analysis and dating work has finally unlocked this great mystery.

“We can now say that this iconic rock is Scottish and not Welsh.”

The Altar Stone is classed as a bluestone, but is very different from the other ones at Stonehenge, as it is about twice the size of some, and weighs six tonnes and is about five metres long, while others are about a maximum of three tonnes.

The stone lies flat and semi-buried at the heart of the prehistoric monument, and is encircled by the famous standing trilithons.

The research was conducted by scientists at Aberystwyth University, University College London and, Curtin University and the University of Adelaide in Australia.

Researchers analysed the age and chemistry of minerals from fragments of the Altar Stone and found it had a remarkable similarity to red sandstone found at the Orcadian Basin in northeast Scotland.

Anthony Clarke, from the Timescales of Mineral Systems Group at Curtin University, who led the study, said the “findings raise fascinating questions about how such a massive stone was able to be transported over the vast distance”.

Mr Clarke believes the altar may have been transported from Scotland via “marine transport” due to “major overland barriers”.

Professor Nick Pearce, from Aberystwyth University, said: “The distance travelled is astonishing for the time.”

Mr Pearce also said the findings had significant implications for our understanding of the Neolithic communities of the British Isles.

He added: “There’s no doubt that this Scottish source shows a high level of societal organisation in the British Isles during the period.

“These findings will have huge ramifications for understanding communities in Neolithic times, their levels of connectivity and their transport systems.

“Hopefully, people will now start to look at the Altar Stone in a slightly different context in terms of how and when it got to Stonehenge, and where it came from.

“I am sure this will lead to some new thinking about the development of Stonehenge and its links to the rest of Neolithic Britain.”

Cigarette smoking hits 80-year low in U.S.


Cigarette smoking in the United States tied an historic low this year with 11% of U.S. adults saying they smoked cigarettes last month, according to Gallup's annual Consumption Habits poll. The survey found perceptions that cigarettes are "harmful" combined with young adults smoking less contributed to the decline.

Aug. 13 (UPI) -- Cigarette smoking in the United States hit an historic low this year, according to Gallup, which has been monitoring smoking trends for eight decades.

The latest survey, based on Gallup's annual Consumption Habits poll conducted in July, shows 11% of U.S. adults said they smoked cigarettes in the past week. That matches Gallup's other lowest outcome in 2022, and comes close to the 12% smoking trend in 2023.

In 1944, when Gallup first questioned Americans about cigarettes, 41% of adults said they had smoked. Smoking peaked in 1954 with 45% of respondents admitting they had recently lit-up a cigarette. By the late 1980s, the smoking rate had declined but was still more than three times what it is today.

In its recent poll, Gallup found fewer people smoke due to perceptions that cigarettes are "very harmful." This year's survey shows 79% of Americans view cigarettes as "very harmful," while 57% view e-cigarettes or vaping in the same way.

"Medical experts have long warned of the health dangers of smoking, and those educational efforts may be a factor in explaining why cigarette smoking is at an 80-year low," according to Gallup.

Gallup also attributes the large drop in cigarette smoking to young adults, who are less likely to smoke cigarettes and more likely to smoke e-cigarettes, according to 2022-2024 data, which says 18% of adults aged 18 to 29 vape.

"The most recent cohort of young adults are responsible for much of the change. They have bucked the historical trends where young adults have been most likely to smoke cigarettes," according to Gallup.

"Today's young adults have substituted e-cigarettes for tobacco cigarettes, as roughly three times as many young adults vape as smoke cigarettes," Gallup added. "While vaping presents fewer health risks than tobacco smoking, public health officials would still prefer U.S. adults not do either."
Federal judge approves disputed Chicago DNC protest route for thousands

Aug. 13 (UPI) -- A planned protest expected to draw thousands of participants during the Democratic National Convention will have to use the current route provided Chicago officials, a federal judge ruled Monday.

U.S. Northern Illinois District Judge Andrea Wood ruled the current route near the convention's site at the United Center enables protesters to "speak near their intended audience" and does not violate their First Amendment rights.

Wood said the lawsuit ultimately regards the protest organizers not getting the "exact route" they wanted during the DNC event that runs from Monday through Aug. 22.

"This falls well short of a First Amendment violation," Wood wrote in a 24-page ruling.

She said Chicago officials have a significant interest in keeping the protesters under control to ensure event security and safety for its participants.

"The need to maintain an accessible route to and from the United Center in case of emergency constitutes a separate significant governmental interest," Wood wrote.

Wood also cited the potential for injury to protesters as a factor in maintaining a reasonable distance from the United Center.

Workers are erecting an iron fence around the United Center and McCormick Place complex in Chicago to help thwart any potential political violence.

"Allowing a crowd of that size ... to march directly alongside an unyielding barrier -- no matter how much of the street is available for pedestrian use -- poses an obvious risk of injury," Wood wrote.

Chicago Police Superintended Larry Snelling on Monday said the police won't allow protesters to come to Chicago and "destroy the city."

Protest organizers filed the federal lawsuit seeking to amend the route so they could get closer to the United Center and to enable potentially thousands of protesters to participate.

The current route running from Chicago's Union Park to the city's Park 578 is too short and winds too much, which would create a "log jam" for tens of thousands of protesters, U.S.-Palestinian Community Network chair Hatem Abudayyeh said.

Protest organizers estimate 25,000 protesters will converge on the event and said the approved route would cause congestion problems, but Wood cited safety as a significant factor in her ruling.

City officials initially offered a protest route in Grant Park that is located 3 miles from the United Center but in June changed the route to make it adjacent to the United Center.

The approved route enables protesters to gather at Union Park on Chicago's near-west side and proceed on a route that takes them along Washington Boulevard to Hermitage Avenue and past a small park near the United Center before turning east onto Lake Street and heading back to Union Park.

The protest organizers want a wider and longer route that would enable them to stay on Washington Boulevard longer and hold a rally close to the United Center

Report: Instagram failed to remove 93% of abusive comments against women politicians

Aug. 14 (UPI) -- The Center for Countering Digital Hate reported Wednesday that Instagram failed to act on 93% of the abusive comments, including death and rape threats, targeting U.S. women politicians.

After using Instagram's own reporting tool to report 1,000 abusive comments, no action was taken against 926 of them, according to the CCDH report.

"When our researchers reported 1,000 of the worst of these comments -- sexist and racist abuse, death and rape threats, and rule-breaking offenses -- Instagram allowed 93% to remain on the platform," the CCDH said in a Wednesday statement. "Instagram's failure to uphold and enforce its community guidelines means the platform is failing women and, by extension, our society's desire for equal opportunity and treatment for women."

Both Democratic and Republican women politicians are being targeted with abusive Instagram comments, including Vice President Kamala Harris, now set to be the Democratic nominee for president. In Harris's case, the CCDH said, 92% of abusive comments remained after being reported.

The CCDH said that the hate speech, threats, and gendered abuse are aimed at pushing women out of political life.

The abusive comments included comments like "death to her and her supporters" and "Make rape legal." Racist abusive comments included "we don't want blacks around us no matter who they are."

According to the CCDH, Instagram replied that the comment about Black people "doesn't go against our Community Guidelines."

Instagram failed to remove a post about Harris that said, "You and your entire family deserve to die a horrible death."

A comment against Rep. Greene, R-Ga., Instagram failed to remove also called for "death to her and her supporters."

"In our study we found that the hate in Representative Marjorie Taylor Greene's comments reflected both the type of abuse we see all women politicians in the sample endure, but also her own incitement of hate against colleagues in Congress," CCDH's statement said.

No action was taken on a post against former House Speaker Pelosi that referenced the hammer attack on her husband Paul Pelosi in their home.

That post said, "Why weren't you home when old hammer head got attacked? It would have been awesome to see your knees in pieces."

A post against Rep. Boebert, R-Colo., allowed to remain on Instagram said, "Personally I wish that blood clot had killed her."

Harris has been targeted by both racist and sexually derogatory comments including racial slurs.

The organization said Instagram must enforce its existing rules against "violent threats and abuse and work with experts in gender-based violence to ensure its current policies align with the lived reality of women and marginalized people in public life."

According to the CCDH, of 560,000 comments on Instagram collected on five Democrat and five Republican female incumbents, over 20,000 were identified as likely to be "toxic" by Google's Perspective AI tool.

The CCDH said in the 2020 U.S. congressional race "it was found that women of color candidates were more likely to receive sexist, racist, and violent abuse online."

In its report the CCDH implored Instagram to transparently enforce its community guidelines against gender-based abuse and violent threats. The report also urged lawmakers to act "to hold social media companies accountable for failing to address abuse."

United States remains last for life expectancy among English-speaking countries

By Dennis Thompson, HealthDay News

Americans continue to rank dead last in life expectancy among English-speaking countries, a new study finds.

People in the United States more often fall prey at younger ages to accidental deaths, homicides and chronic diseases, researchers reported Tuesday in the BMJ Open journal.

On the other hand, Australians had the longest life expectancy of any English speakers, despite their country teeming with deadly sharks, spiders and snakes.

Australian life expectancy is nearly four more years longer than the United States for women and five more years longer for men.

The United States also trails Canada, Ireland, the United Kingdom and New Zealand in life expectancy, researchers found.

However, they said the findings should be seen as an incentive for goal-setting for Americans.

"Yes, we're doing badly, but this study shows what can we aim for," said senior researcher Jessica Ho, an associate professor of sociology and demography at Penn State. "We know these gains in life expectancy are actually achievable because other large countries have already done it."

For the study, researchers compared life expectancy between English-speaking nations using data from the World Health Organization and the international Human Mortality Database.

The data showed that the United States has had the worst life expectancy among these countries since the early 1990s.

U.S. women live an average of 81.5 years, and men 76.5 years, researchers reported.

The Irish have experienced the largest gains in life expectancy, with men's lifespans increasing by about eight years and women's by more than 6.5 years.

Results show that life expectancy varies widely within the United States, depending on where a person lives.

California and Hawaii had some of the highest life expectancies, with women living 83 to 84 years and men living 77.5 to 78.4 years, researchers said.

But states in the American South had some of the lowest life expectancies observed among all the nations, with women averaging 72.6 to 80 years and men averaging 69.3 to 74.4 years.

"One of the main drivers of why American longevity is so much shorter than in other high-income countries is our younger people die at higher rates from largely preventable causes of death, like drug overdose, car accidents and homicide," Ho said in a Penn State news release.

Middle-aged Americans ages 45 to 64 also have higher rates of death from drugs, alcohol and chronic illnesses like heart disease, Ho added.

"Some of the latter could be related to sedentary lifestyle, high rates of obesity, unhealthy diet, stress and a history of smoking," Ho said. "It's likely that these patterns of unhealthy behaviors put Americans at a disadvantage in terms of their health and vitality."

Australia is a large country, and many people there use cars for transportation and own firearms, Ho noted. However, recent policies like gun control laws have helped vault Australia to the top of the life expectancy ratings, Ho said.

"What the study shows is that a peer country like Australia far outperforms the U.S. and was able to get its young adult mortality under control," Ho said. "It has really low levels of gun deaths and homicides, lower levels of drug and alcohol use and better performance on chronic diseases, the latter of which points to lifestyle factors, health behaviors and health care performance."

"Australia is a model for how Americans can do better and achieve not only a higher life expectancy but also lower geographic inequality in life expectancy," Ho concluded.

NASA just shut down a planetary defence mission that tracks asteroids. Now what?

The Conversation
August 14, 2024 

Asteroids (Festa/SHutterstock.com)

Launched in 2011, NASA’s NEOWISE mission operated in Earth’s orbit until late last week. It detected more than 3,000 near-Earth objects or NEOs – asteroids or comets whose orbits can bring them close to Earth, even with the possibility of a collision. NEOWISE was shut down on August 8.

Surveying the population of NEOs is central to the emerging concept of planetary defence. That is, understanding and mitigating the risk of collision from asteroids large enough to do significant damage to Earth.

NEOWISE has made fundamental contributions to establishing the knowledge base for planetary defence, with more than 200 of the 3,000 objects it studied not known to us previously.

Now at mission end, and commanded by NASA to shut itself down, NEOWISE will re-enter Earth’s atmosphere before the end of this year. Where does that leave us with defending our planet?


All Known Asteroids in the Solar System (1999–2018)



From astrophysics to planetary defence

NEOWISE started life as a different mission, simply called WISE (Wide-field Infrared Survey Explorer). It was designed to study the infrared radiation from distant galaxies in the universe.

Infrared means “beyond red” – infrared light sits just past the red end of the spectrum of colours humans can see. We know infrared radiation better as the heat from the Sun, for example, or from a radiator keeping us warm in winter.




Infrared light is just outside the part of the spectrum that the human eye can see.

When the coolant on the WISE mission ran out and these sensitive observations of galaxies couldn’t be carried out any more, NASA granted a mission extension under the NEOWISE name. They realised the telescope system was still sensitive enough to detect asteroids and comets that come close to Earth and the Sun, thereby having a very strong infrared signal.

NASA has an extraordinary history of squeezing extra life out of missions that reach completion. In this case, NEOWISE represented an entire second life, in an entirely different area of research.

How will we defend Earth now?



As well as the discovery and study of thousands of NEOs, NEOWISE established the foundation of knowledge that has informed a new, dedicated planetary defence mission. NASA’s NEO Surveyor will be launched in 2027.

NEO Surveyor’s goal is to discover approximately two thirds of all NEOs larger than 140 metres in diameter, over a five year baseline survey. This is a big step toward fulfilling the mandate United States Congress has provided to NASA: to discover 90% of all NEOs in this size range.

If they hit Earth, asteroids of this size could cause mass casualties if the impact were over a large metropolitan region.


You might think this poses a bit of a risk – shutting down NEOWISE three years before launching NEO Surveyor. What happens if one of these big asteroids comes our way in the next few years?

The risks are very small, as estimates show asteroids 140 metres in diameter impact Earth only approximately every 20,000 years. So, we would have to be extremely unlucky to have one in any given three-year period, especially impacting a place that would cause a large amount of damage. Only around 3% of Earth’s surface is occupied by urban areas.

NASA doesn’t really have much of a choice with the end of NEOWISE. The Sun’s 11-year activity cycle is picking up and causing Earth’s upper atmosphere, the ionosphere, to thicken. NEOWISE is flying through this ionosphere and can’t raise its orbit, so the ionosphere is inevitably dragging NEOWISE back to Earth.


NEO Surveyor started construction in 2023, so a 2027 launch is pretty impressively rapid, which is minimising the gap between NEOWISE and NEO Surveyor.

NEOWISE is scheduled to enter Earth’s atmosphere before the end of the year, but we don’t know precisely when.

Weighing almost 700kg, some of NEOWISE itself is likely to impact the surface of Earth. Hopefully it stays away from populated areas in the process – some recent re-entry events have resulted in space debris falling reasonably close to populated areas.

An asteroid is coming! What next?

Knowing about an asteroid on a collision course with Earth is one thing. Doing something about it is another thing altogether.

Huge steps toward planetary defence occurred two years ago, when the DART mission flew to an asteroid, impacted it, and changed its trajectory. This demonstrated it’s possible to change the course of asteroids, which could be used in the future to protect Earth from a collision.

Predicting potential Earth impacts as far as possible in advance, years preferably, gives the DART-style technology approach a chance.

The pioneering work of NEOWISE, and the upcoming comprehensive observations of NEO Surveyor, will place an enormous amount of information in our scientific bank, which will never go out of date and will be the basis for planetary defence for perhaps hundreds of years into the future.

WASHINGTON, Aug. 13, 2024 – Mars has a notoriously inhospitable environment, with temperatures that fluctuate dramatically over the course of a Martian day and average minus 80 degrees Fahrenheit. Its surface is mostly covered in red dust, with terrain typified by craters, canyons, and volcanoes. And its atmosphere is extremely thin, comprising only about 1% of the density of Earth’s.

Needless to say, measuring wind speeds on the red planet is challenging. Martian landers have been able capture measurements — some gauging the cooling rate of heated materials when winds blow over them, others using cameras to image “tell-tales” that blow in the wind. Both anemometric methods have yielded valuable insight into the planet’s climate and atmosphere.

But there’s still room for improvement in the astronomical toolshed, especially as plans to send astronauts to Mars unfold in the coming years.

In JASA, published on behalf of the Acoustical Society of America by AIP Publishing, researchers from Canada and the U.S. demonstrated a novel sonic anemometric system featuring a pair of narrowband piezoelectric transducers to measure the travel time of sound pulses through Martian air. The study accounted for variables including transducer diffraction effects and wind direction.

“By measuring sound travel time differences both forward and backward, we can accurately measure wind in three dimensions,” said author Robert White. “The two major advantages of this method are that it’s fast and it works well at low speeds.”

The researchers hope to be able to measure up to 100 wind speeds per second and at speeds as low as 1 cm/s, a remarkable contrast to previous methods that could register only about 1 wind speed per second and struggled to track speeds below 50 cm/s. 

“By measuring quickly and accurately, we hope to be able to measure not only mean winds, but also turbulence and fluctuating winds,” said White. “This is important for understanding atmospheric variables that could be problematic for small vehicles such as the Ingenuity helicopter that flew on Mars recently.”

The researchers characterized ultrasonic transducers and sensors over a wide range of temperatures and a narrow range of pressures in carbon dioxide, the primary atmospheric gas on Mars. With their selections, they showed only nominal error rates would result from temperature and pressure changes.

“The system we’re developing will be 10 times faster and 10 times more accurate than anything previously used,” said White. “We hope it will produce more valuable data as future missions to Mars are considered and provide useful information on the Martian climate, perhaps also with implications for better understanding the climate of our own planet.”

 NASA scientists hope to use Cold Atom Lab to better understand dark energy

Aug. 13 (UPI) -- For the first time, ultra-cold atoms have been used to detect changes in the surrounding environment in space, taking a step of revolutionizing how quantum science can be used.

A new study released Tuesday in the science journal Nature Communications, NASA's Cold Atom Lab on the International Space Station measured subtle vibrations of the orbiting lab.

The team using the Cold Atom Lab made their measurements with an interferometer, a quantum tool that can accurately measure gravity, magnetic fields and other forces. Earth-bound scientists use the tool to study gravity and technologies to help aircraft and ship navigation.

Physicists hope using such technology in space will allow for longer measurement times and improve instrument sensitivity.

"Reaching this milestone was incredibly challenging, and our success was not always a given," Jason Williams, the Cold Atom Lab project scientist at NASA's Jet Propulsion Laboratory, said in a statement. "It took dedication and a sense of adventure by the team to make this happen."

Researchers said such precise measurements of gravity could benefit the understanding of dark matter and dark energy, which remains a mystery to modern science. Dark matter, which is an invisible substance, is five times more common than the matter used to make up the planets and stars.

"Atom interferometry could also be used to test Einstein's theory of general relativity in new ways," University of Virginia professor Cass Sackett, a Cold Atom Lab principal investigator and co-author of the study.

"This is the basic theory explaining the large-scale structure of our universe, and we know that there are aspects of the theory that we don't understand correctly. This technology may help us fill in those gaps and give us a more complete picture of the reality we inhabit."

SAN ANTONIO — August 13, 2024 —Using data from NASA’s James Webb Space Telescope, a Southwest Research Institute-led team has confirmed hydroxyl molecules on the surface of the metallic asteroid Psyche. The presence of hydrated minerals suggests a complex history for Psyche, important context for the NASA spacecraft en route to this interesting asteroid orbiting the Sun between Mars and Jupiter.

At about 140 miles in diameter, Psyche is one of the most massive objects in the main asteroid belt. Previous observations indicate that Psyche is a dense, largely metallic object that could be a leftover core from a planet that experienced a catastrophic collision. On Oct. 13, 2023, NASA launched the Psyche spacecraft, which is traveling 2.2 billion miles to arrive at the asteroid in August 2029.

“Using telescopes at different wavelengths of infrared light, the SwRI-led research will provide different but complementary information to what the Psyche spacecraft is designed to study,” said SwRI’s Dr. Tracy Becker, second author of a new American Astronomical Society’s Planetary Science Journal paper discussing these findings.

“Our understanding of solar system evolution is closely tied to interpretations of asteroid composition, particularly the M-class asteroids that contain higher concentrations of metal,” said Center for Astrophysics | Harvard & Smithsonian’s Dr. Stephanie Jarmak, the paper’s lead author, who conducted much of this research while at SwRI. “These asteroids were initially thought to be the exposed cores of differentiated planetesimals, a hypothesis based on their spectral similarity to iron meteorites.”

The Webb data point to hydroxyl and perhaps water on Psyche’s surface. The hydrated minerals could result from external sources, including impactors. If the hydration is native or endogenous, then Psyche may have a different evolutionary history than current models suggest.

“Asteroids are leftovers from the planetary formation process, so their compositions vary depending on where they formed in the solar nebula,” said SwRI’s Dr. Anicia Arredondo, another co-author. “Hydration that is endogenous could suggest that Psyche is not the remnant core of a protoplanet. Instead, it could suggest that Psyche originated beyond the ‘snow line,’ the minimum distance from the Sun where protoplanetary disc temperatures are low enough for volatile compounds to condense into solids, before migrating to the outer main belt.”

However, the paper found the variability in the strength of the hydration features across the observations implies a heterogeneous distribution of hydrated minerals. This variability suggests a complex surface history that could be explained by impacts from carbonaceous chondrite asteroids thought to be very hydrated.

Understanding the location of asteroids and their compositions tells us how materials in the solar nebula were distributed and have evolved since formation. How water is distributed in our solar system will provide insight into the distribution of water in other solar systems and, because water is necessary for all life on Earth, will drive where to look for potential life, both in our solar system and beyond.

NASA’s Webb telescope, developed in partnership with the European and Canadian space agencies, is part of the Space Telescope Science Institute, operated by the Association of Universities for Research in Astronomy. The Psyche mission is led by Arizona State University. NASA’s Jet Propulsion Laboratory is responsible for mission management, operations and navigation.

SpaceX is aiming to break new barriers in polar exploration with the first manned space mission over the Earth's poles -- a private flight commanded by a crypto entrepreneur later this year, the company said Tuesday.

The mission, dubbed "Fram2" after a 19th century polar expedition schooner, is due to last between three to five days, and was purchased by Chun Wang, a wealthy bitcoin pioneer who founded f2pool and stakefish, for an undisclosed amount.

He will be joined by three polar experts: Norwegian filmmaker Jannicke Mikkelsen, German robotics researcher Rabea Rogge, and Australian polar adventurer Eric Philips.

It is the latest foray by the aerospace industry into private space tourism, growing fast in the United States in recent years.

"From mission proposal, planning, trajectory design, to crew selection, everything has been done by the customer," Wang, reportedly born and raised in China but now a Maltese citizen, said in a post on X.

"A new chapter in space exploration is unfolding before our eyes," he said.

Satellites have flown over the poles, but due to the Earth's rotation, reaching them can take more power, while radiation can also be an issue, astrophysicist Jonathan McDowell told AFP.

"To date, the highest inclination achieved by human spaceflight has been the Soviet Vostok 6 mission, at 65°," according to the mission website.

The poles are not visible from the International Space Station (ISS).

The mission will use a SpaceX Dragon capsule equipped with an observation dome. The craft will fly at an altitude of between 265 and 280 miles (425 and 450 kilometers), according to SpaceX, owned by mercurial billionaire Elon Musk.

The crew plans to conduct research including taking the first X-ray images in space and studying an aurora-like light phenomenon, according to SpaceX.

SpaceX has flown 13 manned missions in the last four years. It carries Nasa astronauts to the ISS, but has also carried out several space tourism missions, including the first in 2021, named Inspiration4, financed by American billionaire Jared Isaacman.


"Until 2021, space missions were solely the privilege of governments," Wang wrote, adding: "Then @inspiration4x came along and changed everything."

SpaceX is set to launch another private mission, Polaris Dawn on August 26, carrying four crew members including Isaacman.

It is scheduled to include the first private spacewalk.

Spying from space: How satellites can help identify and rein in a potent climate pollutant

LONG READ

On a blustery day in early March, the who’s who of methane research gathered at Vandenberg Space Force Base in Santa Barbara, California. Dozens of people crammed into a NASA mission control center. Others watched from cars pulled alongside roads just outside the sprawling facility. Many more followed a livestream. They came from across the country to witness the launch of an oven-sized satellite capable of detecting the potent planet-warming gas from space.

The amount of methane, the primary component in natural gas, in the atmosphere has been rising steadily over the last few decades, reaching nearly three times as much as preindustrial times. About a third of methane emissions in the United States occur during the extraction of fossil fuels as the gas seeps from wellheads, pipelines, and other equipment. The rest come from agricultural operations, landfills, coal mining, and other sources. Some of these leaks are large enough to be seen from orbit. Others are miniscule, yet contribute to a growing problem.

Identifying and repairing them is a relatively straightforward climate solution. Methane has a warming potential about 80 times higher than carbon dioxide over a 20-year period, so reducing its levels in the atmosphere can help curb global temperature rise. And unlike other industries where the technology to decarbonize is still relatively new, oil and gas companies have long had the tools and know-how to fix these leaks.

MethaneSAT, the gas-detecting device launched in March, is the latest in a growing armada of satellites designed to detect methane. Led by the nonprofit Environmental Defense Fund, or EDF, and more than six years in the making, the satellite has the ability to circle the globe 15 times a day and monitor regions where 80 percent of the world’s oil and gas is produced. Along with other satellites in orbit, it is expected to dramatically change how regulators and watchdogs police the oil and gas industry.

“Companies do a good job of complying with the law, but the law has been insufficient,” said Danielle Fugere, president and chief counsel at As You Sow, a nonprofit group that has used shareholder advocacy to push fossil fuel producers to tackle climate change. “So this change will increase incentives for reducing methane emissions.”

Those at Vandenberg or watching online were a bit on edge. A lot could go wrong. The SpaceX rocket carrying the satellite into orbit could explode. A week before, engineers worried about the device that holds the $88 million spacecraft in place during launch and pushes it into space. “That made us a little nervous,” recalled Steven Wofsy, an atmospheric scientist at Harvard University and a key architect of the project along with Steven Hamburg, the scientist who leads MethaneSAT at EDF. If that didn’t go wrong, the satellite could still fail to deploy or have difficulty communicating with its minders on Earth.

They needn’t have worried. A couple hours after the rocket blasted off, Wofsy, Hamburg, and his colleagues watched on a television at a hotel about two miles away as their creation was ejected into orbit. It was a jubilant moment for members of the team, many of whom had traveled to Vandenberg with their partners, parents, and children. “Everybody spontaneously broke into a cheer,” Wofsy said. “You [would’ve] thought that your team scored a touchdown during overtime.”

The data the satellite generates in the coming months will be publicly accessible — available for environmental advocates, oil and gas companies, and regulators alike. Each has an interest in the information MethaneSAT will beam home. Climate advocates hope to use it to push for more stringent regulations governing methane emissions and to hold negligent operators accountable. Fossil fuel companies, many of which do their own monitoring, could use the information to pinpoint and repair leaks, avoiding penalties and recouping a resource they can sell. Regulators could use the data to identify hotspots, develop targeted policies, and catch polluters. For the first time, the Environmental Protection Agency is taking steps to be able to use third-party data to enforce its air quality regulations, developing guidelines for using the intelligence satellites like MethaneSAT will provide. The satellite is so important to the agency’s efforts that EPA Administrator Michael Regan was in Santa Barbara for the launch as was a congressional lawmaker. Activists hailed the satellite as a much-needed tool to address climate change.


“This is going to radically change the amount of empirically observed data that we have and vastly increase our understanding of the amount of methane emissions that are currently happening and what needs to be done to reduce them,” said Dakota Raynes, a research and policy manager at the environmental nonprofit Earthworks. “I’m hopeful that gaining that understanding is going to help continue to shift the narrative towards [the] phase down of fossil fuels.”

With the satellite safely orbiting 370 miles above the Earth’s surface, the mission enters a critical second phase. In the coming months, EDF researchers will calibrate equipment and ensure the satellite works as planned. By next year, it is expected to transmit reams of information from around the world. Its success will depend on the quality of the data it can produce and — perhaps more importantly — how that data is put to use.

The European Space Agency released the first global measurements of atmospheric methane three years after launching the Environmental Satellite, or Envisat, in 2002. In 2009, three years before the Envisat mission ended, Japan’s Greenhouse Gases Observing Satellite, or GOSAT, made its orbital debut. These early progenitors established a new era of worldwide emissions accounting, but they lacked the geographic precision required to inform meaningful action.


In the years since, a hodgepodge of governmental agencies and private-sector organizations has deployed 23 more satellites, including MethaneSAT, to glean additional insights. Some improved upon the pioneering technology by mapping global emissions with greater fidelity and surveying the world with what one could call a wide-angle view. But most measure emissions in targeted areas with what amounts to a telephoto lens.

The images they collect, however, are nothing like what a Nikon might capture, because methane, like most gases, is invisible to humans. So these satellites rely on a spectrometer to reveal the infrared signature the gas leaves behind, exposing not only its presence, but its concentration.

How large a chunk of the world a satellite can map, and the resolution it can provide, depends primarily upon the magnifying power of its telescope. Typically, a higher magnification allows the examination of smaller areas in greater detail, while a lower magnification is best for analyzing vast areas in less detail. The instruments aboard each satellite have all been designed with a unique combination of sensitivities and resolutions tailored to its primary mission. Given GOSAT, for example, was designed to track methane and greenhouse gas concentrations over the entire planet in coarse resolutions, it would have no trouble measuring methane emissions across Southern California and beyond, but it would condense Santa Monica into a single pixel. On the other hand, with the privately owned GHGSat focused on taking images of precise areas and identifying the facilities responsible for emissions, its satellites could map the city of Santa Monica in exquisite detail and pinpoint a sizable methane leak to within 80 to 160 feet, but would struggle to provide any indication of what’s happening beyond the city.


EDF saw an opportunity to create a satellite capable of doing both by designing MethaneSAT’s instrument to take images that cover 125 miles of Earth’s surface, enough to capture most of an oil field spanning dozens of miles in a single frame with sufficient resolution to identify small groups of wells and other infrastructure within that expanse. The nonprofit and its researchers began to see the need for such a device about a decade ago, at the height of the fracking boom. The organization was coordinating the work of hundreds of scientists who “were creating more data about methane emissions from the oil and gas industry in the U.S. than anyone had,” Hamburg said, “by orders of magnitude.”

EDF flew spectrometers aboard airplanes over oil fields, and discovered that the EPA had severely underestimated the amount of methane emitted by oil and gas operations. Although these studies proved invaluable, the scientists couldn’t conduct these labor-intensive, aerial campaigns at the scale or frequency required to understand global methane emissions and how they evolved. That piecemeal approach made clear that no one understood the extent of the problem. Even for the areas they could image, “you’re getting snapshots,” Hamburg said, “but not a motion picture.”


Hamburg and his colleagues set out to determine what it would take to monitor the world’s most productive oil fields on a near-daily basis to determine where, and how much, methane escaped and how those emissions were changing over time. “We’d done enough looking,” Hamburg said, “that we didn’t think the existing satellites or the planned satellites were going to provide that data.”


As they pondered how to fill this gap, Robert Harris, EDF’s lead scientist until his passing in 2021, encouraged Hamburg to get in touch with Wofsy. Wofsy had promised himself he would never get involved in a satellite mission, but the prospect of the measurements this one could collect became too tantalizing to pass up. The more the two Stevens came together to talk and “mind meld,” Hamburg said, the more they realized they shared a vision for a mission that could slot neatly between wide-angle global mappers and the telephoto point imagers, filling a gap that, until then, no one had aimed to address.


The ability to measure emissions across large areas and identify the worst polluters could reshape how regulators design policy. In recent years, climate scientists and activists have spotlighted “super emitters” — large leaks spewing a disproportionate amount of methane. But EDF’s research has shown that focusing on gross polluters risks overlooking the cumulative contributions of small, persistent leaks. In 2022, its researchers found that although low-production oil and gas wells produce just 6 percent of the nation’s fossil fuels, they generate around half of the industry’s methane emissions. That is despite releasing pollution at less than one-tenth the rate of even the smallest super emitters. The data coming from EDF’s new satellite will be able to help quantify and constrain the emissions coming from gross polluters and smaller sources alike — something that will prove invaluable.

“MethaneSAT will play a very crucial role with advocacy and policymaking,” by showing not only a given region’s total methane emissions, but how that changes over time, said Jean-Francois Gauthier, a senior vice president at GHGSat, which operates 12 of its own methane-monitoring satellites and markets services and data to both the public and private sectors, including fossil fuel companies. “Now you can start having very targeted policies and regulations.”

Given the sophistication of tools like MethaneSAT and the four satellites GHGSat plans to add to its flotilla later this year, it is ironic that the EPA’s current enforcement strategy is fairly low tech. The agency requires the fossil fuel industry to report its own emissions and augments that data with occasional aerial surveillance — an approach that limits it to capturing emissions for a specific period of time over a limited area. Oil and gas operators must estimate the emissions from their equipment, but the methodology is largely based on outdated data, and they aren’t required to report large releases due to malfunctions.


As a result, the EPA is underestimating the scale of methane emissions from the oil and gas sector by as much as 76 percent, according to researchers. Shayla Powell, an EPA representative told Grist that the discrepancies between the agency’s analysis and satellite-based estimates may stem from the needto draw national conclusions from local observations. Super-emitters “may not be accurately captured using current methods,” the representative said. “EPA continues to work with researchers to compare results, identify specific sources of discrepancies, and make improvements.”

Recognizing the global reach and nearly real-time coverage that satellites can provide, the EPA plans to capitalize on all that data. Its new Superemitter Program will allow certified third parties to provide the agency with data documenting leaks. It will then reach out to the company responsible for the emissions, which will have five days to open an investigation and 15 days to report to the EPA. A provision in the Inflation Reduction Act directs the EPA to charge $900 per metric ton of methane released beyond a certain threshold. The trove of information coming back from space can help the agency measure how much operators are spewing.

The EPA places strict detection and resolution requirements on the data it will accept, but even if one firm’s satellite can’t take photos that meet those guidelines, its findings could inform the work of others and provide the agency with actionable information. “In the space business, it’s called ‘tip and cue,’” said Riley Duren, who leads Carbon Mapper, a nonprofit dedicated to measuring planet-warming emissions. “If one satellite sees something, it can tip off another one and they can queue up measurements to follow up.”


But whether all the data will ultimately help reduce methane emissions remains an open question. For years, Sharon Wilson, a self-proclaimed methane hunter and director of the environmental group Oilfield Witness, has been scouring oil and gas fields nationwide and documenting massive leaks. She uses an optical gas imaging camera, which makes the invisible emissions visible, to document how fossil fuel operators have been flaring natural gas with impunity. Over the last eight years, she has submitted more than 500 complaints with video evidence of leaks in the Permian Basin in West Texas and other oil fields to the Texas Commission on Environmental Quality, the agency responsible for enforcing environmental rules in the state. It has rarely taken action. Wilson worries that any satellite data will similarly be dismissed.

“The bottom line on this whole thing is it doesn’t matter how many thermographers we have, boots on the ground, satellites flying in the air, people with drones and airplanes and all the other technology, none of it matters if you don’t stop methane,” Wilson said. “None of it counts.”

If operators fail to take action after being notified through the EPA’s Superemitter Program, it’s unclear whether enforcement action will fall to the states. The EPA has delegated responsibility for enforcing parts of the Clean Air Act to states, which has led to disparities in accountability. The new methane rules finalized by the EPA late last year require states to develop an implementation plan. If state plans are inadequate, the agency is expected to roll out a federal one. When the EPA has taken this approach with other pollutants such as smog, states like Texas and Louisiana have often submitted inadequate implementation plans.

How the EPA chooses to follow through may not be clear for a couple more years. The agency is currently vetting those interested in submitting methane data. Publication of any data third parties provide may not occur until 2026, at which point the EPA will need to take appropriate action against polluters.

“You don’t just need people to collect the data attributed to an operator or a facility,” said Raynes, the Earthworks researcher. “You also need people who are actually going to follow through to make sure that that operator fixes the problem. There’s a little less clarity in all of [this] about whether that’s being accurately planned for.”

Satellites — no matter how sophisticated — have limitations, and the responsibility to take action falls to regulators. Ultimately, having more granular data makes it more difficult for oil and gas companies and regulators to deny that leaks exist. “Having that greater access to that finer level of actual, empirically-observed measurement is going to change the conversation about methane,” said Raynes.

This article has been updated to clarify that the images of the methane leaks in Georgia, Louisiana, and Texas were captured by Carbon Mapper.
