Американсько-російська співпраця в космосі була поставлена під сумнів після вторгнення Москви в Україну в лютому 2022 року

A Japanese space start-up will attempt Tuesday to become the first private company to put a lander on the Moon.
If all goes to plan, ispace’s Hakuto-R Mission 1 lander will start its descent towards the lunar surface at around 15:40 GMT.
It will slow its orbit some 100 kilometers above the Moon, then adjust its speed and altitude to make a “soft landing” around an hour later.
Success is far from guaranteed. In April 2019, Israeli organization SpaceIL watched their lander crash into the Moon’s surface.
ispace has announced three alternative landing sites and could shift the lunar descent date to April 26, May 1 or May 3, depending on conditions.
“What we have accomplished so far is already a great achievement, and we are already applying lessons learned from this flight to our future missions,” ispace founder and CEO Takeshi Hakamada said earlier this month.
“The stage is set. I am looking forward to witnessing this historic day, marking the beginning of a new era of commercial lunar missions.”
The lander, standing just over two meters tall and weighing 340 kilograms, has been in lunar orbit since last month.
It was launched from Earth in December on one of SpaceX’s Falcon 9 rockets after several delays.
So far only the United States, Russia and China have managed to put a robot on the lunar surface, all through government-sponsored programs.
However, Japan and the United States announced last year that they would cooperate on a plan to put a Japanese astronaut on the Moon by the end of the decade.

The lander is carrying several lunar rovers, including a miniature Japanese model of just eight centimeters that was jointly developed by Japan’s space agency with toy manufacturer Takara Tomy.
The mission is also being closely watched by the United Arab Emirates, whose Rashid rover is aboard the lander as part of the nation’s expanding space program.
The Gulf country is a newcomer to the space race but sent a probe into Mars’ orbit in 2021. If its rover successfully lands, it will be the Arab world’s first Moon mission.
Hakuto means “white rabbit” in Japanese and references Japanese folklore that a white rabbit lives on the Moon.
The project was one of five finalists in Google’s Lunar X Prize competition to land a rover on the Moon before a 2018 deadline, which passed without a winner.
With just 200 employees, ispace has said it “aims to extend the sphere of human life into space and create a sustainable world by providing high-frequency, low-cost transportation services to the Moon.”
Hakamada has touted the mission as laying “the groundwork for unleashing the Moon’s potential and transforming it into a robust and vibrant economic system.”
The firm believes the Moon will support a population of 1,000 people by 2040, with 10,000 more visiting each year.
It plans a second mission, tentatively scheduled for next year, involving both a lunar landing and the deployment of its own rover.

The U.S. Space Force said on Monday that Elon Musk’s SpaceX was granted approval to lease a second rocket launch complex at a military base in California, setting the space company up for its fifth launch site in the United States.
Under the lease, SpaceX will launch its workhorse Falcon rockets from Space Launch Complex-6 at Vandenberg Space Force Base, a military launch site north of Los Angeles where the space company operates another launchpad. It has two others in Florida and its private Starbase site in south Texas.
A Monday night Space Force statement said a letter of support for the decision was signed on Friday by Space Launch Delta 30 commander Col. Rob Long. The statement did not mention a duration for SpaceX’s lease.
The new launch site, vacated last year by the Boeing-Lockheed joint venture United Launch Alliance, gives SpaceX more room to handle an increasingly busy launch schedule for commercial, government and internal satellite launches.
Vandenberg Space Force Base allows for launches in a southern trajectory over the Pacific Ocean, which is often used for weather-monitoring, military or spy satellites that commonly rely on polar Earth orbits.
SpaceX’s grant of Space Launch Complex-6 comes as rocket companies prepare to compete for the Pentagon’s Phase 3 National Security Space Launch program, a watershed military launch procurement effort expected to begin in the next year or so.

Twitter accounts operated by authoritarian governments in Russia, China and Iran are benefiting from recent changes at the social media company, researchers said Monday, making it easier for them to attract new followers and broadcast propaganda and disinformation to a larger audience.
The platform is no longer labeling state-controlled media and propaganda agencies, and will no longer prohibit their content from being automatically promoted or recommended to users. Together, the two changes, both made in recent weeks, have supercharged the Kremlin’s ability to use the U.S.-based platform to spread lies and misleading claims about its invasion of Ukraine, U.S. politics and other topics.
Russian state media accounts are now earning 33% more views than they were just weeks ago, before the change was made, according to findings released Monday by Reset, a London-based non-profit that tracks authoritarian governments’ use of social media to spread propaganda. Reset’s findings were first reported by The Associated Press.
The increase works out to more than 125,000 additional views per post. Those posts included ones suggesting the CIA had something to do with the September 11, 2001, attacks on the U.S., that Ukraine’s leaders are embezzling foreign aid to their country, and that Russia’s invasion of Ukraine was justified because the U.S. was running clandestine biowarfare labs in the country.
State media agencies operated by Iran and China have seen similar increases in engagement since Twitter quietly made the changes.
The about-face from the platform is the latest development since billionaire Elon Musk purchased Twitter last year. Since then, he’s ushered in a confusing new verification system and laid off much of the company’s staff, including those dedicated to fighting misinformation, allowed back neo-Nazis and others formerly suspended from the site, and ended the site’s policy prohibiting dangerous COVID-19 misinformation. Hate speech and disinformation have thrived.
Before the most recent change, Twitter affixed labels reading “Russia state-affiliated media” to let users know the origin of the content. It also throttled back the Kremlin’s online engagement by making the accounts ineligible for automatic promotion or recommendation—something it regularly does for ordinary accounts as a way to help them reach bigger audiences.
The labels quietly disappeared after National Public Radio and other outlets protested Musk’s plans to label their outlets as state-affiliated media, too. NPR then announced it would no longer use Twitter, saying the label was misleading, given NPR’s editorial independence, and would damage its credibility.
Reset’s conclusions were confirmed by the Atlantic Council’s Digital Forensic Research Lab (DFRL), where researchers determined the changes were likely made by Twitter late last month. Many of the dozens of previously labeled accounts were steadily losing followers since Twitter began using the labels. But after the change, many accounts saw big jumps in followers.
RT Arabic, one of Russia’s most popular propaganda accounts on Twitter, had fallen to less than 5,230,000 followers on January 1, but rebounded after the change was implemented, the DFRL found. It now has more than 5,240,000 followers.
Before the change, users interested in seeking out Kremlin propaganda had to search specifically for the account or its content. Now, it can be recommended or promoted like any other content.
“Twitter users no longer must actively seek out state-sponsored content in order to see it on the platform; it can just be served to them,” the DFRL concluded.
Twitter did not respond to questions about the change or the reasons behind it. Musk has made past comments suggesting he sees little difference between state-funded propaganda agencies operated by authoritarian strongmen and independent news outlets in the west.
“All news sources are partially propaganda,” he tweeted last year, “some more than others.”

The AI bot ChatGPT has passed exams, written poetry, and deployed in newsrooms, and now politicians are seeking it out — but experts are warning against rapid uptake of a tool also famous for fabricating “facts.”
The chatbot, released last November by U.S. firm OpenAI, has quickly moved center stage in politics — particularly as a way of scoring points.
Japanese Prime Minister Fumio Kishida recently took a direct hit from the bot when he answered some innocuous questions about health care reform from an opposition MP.
Unbeknownst to the PM, his adversary had generated the questions with ChatGPT. He also generated answers that he claimed were “more sincere” than Kishida’s.
The PM hit back that his own answers had been “more specific.”
French trade union boss Sophie Binet was on-trend when she drily assessed a recent speech by President Emmanuel Macron as one that “could have been done by ChatGPT.”
But the bot has also been used to write speeches and even help draft laws.
“It’s useful to think of ChatGPT and generative AI in general as a cliche generator,” David Karpf of George Washington University in the U.S. said during a recent online panel.
“Most of what we do in politics is also cliche generation.”
‘Limited added value’
Nowhere has the enthusiasm for grandstanding with ChatGPT been keener than in the United States.
Last month, Congresswoman Nancy Mace gave a five-minute speech at a Senate committee enumerating potential uses and harms of AI — before delivering the punchline that “every single word” had been generated by ChatGPT.
Local U.S. politician Barry Finegold had already gone further though, pronouncing in January that his team had used ChatGPT to draft a bill for the Massachusetts Senate.
The bot reportedly introduced original ideas to the bill, which is intended to rein in the power of chatbots and AI.
Anne Meuwese from Leiden University in the Netherlands wrote in a column for Dutch law journal RegelMaat last week that she had carried out a similar experiment with ChatGPT and also found that the bot introduced original ideas.
But while ChatGPT was to some extent capable of generating legal texts, she wrote that lawmakers should not fall over each other to use the tool.
“Not only is much still unclear about important issues such as environmental impact, bias and the ethics at OpenAI … the added value also seems limited for now,” she wrote.
Agitprop bots
The added value might be more obvious lower down the political food chain, though, where staffers on the campaign trail face a treadmill of repetitive tasks.
Karpf suggested AI could be useful for generating emails asking for donations — necessary messages that were not intended to be masterpieces.
This raises an issue of whether the bots can be trained to represent a political point of view.
ChatGPT has already provoked a storm of controversy over its apparent liberal bias — the bot initially refused to write a poem praising Donald Trump but happily churned out couplets for his successor as U.S. President Joe Biden.
Billionaire magnate Elon Musk has spied an opportunity. Despite warning that AI systems could destroy civilization, he recently promised to develop TruthGPT, an AI text tool stripped of the perceived liberal bias.
Perhaps he needn’t have bothered. New Zealand researcher David Rozado already ran an experiment retooling ChatGPT as RightWingGPT — a bot on board with family values, liberal economics and other right-wing rallying cries.
“Critically, the computational cost of trialling, training and testing the system was less than $300,” he wrote on his Substack blog in February.
Not to be outdone, the left has its own “Marxist AI.”
The bot was created by the founder of Belgian satirical website Nordpresse, who goes by the pseudonym Vincent Flibustier.
He told AFP his bot just sends queries to ChatGPT with the command to answer as if it were an “angry trade unionist.”
The malleability of chatbots is central to their appeal but it goes hand-in-hand with the tendency to generate untruths, making AI text generators potentially hazardous allies for the political class.
“You don’t want to become famous as the political consultant or the political campaign that blew it because you decided that you could have a generative AI do [something] for you,” said Karpf.

The Biden administration announced more than $80 million in funding Thursday in a push to produce more solar panels in the U.S., make solar energy available to more people, and pursue superior alternatives to the ubiquitous sparkly panels made with silicon.
The initiative, spearheaded by the U.S. Department of Energy (DOE) and known as Community solar, encompasses a variety of arrangements where renters and people who don’t control their rooftops can still get their electricity from solar power. Two weeks ago, Vice President Kamala Harris announced what the administration said was the largest community solar effort ever in the United States.
Now it is set to spend $52 million on 19 solar projects across a dozen states, including $10 million from the infrastructure law, as well as $30 million on technologies that will help integrate solar electricity into the grid.
The DOE also selected 25 teams to participate in a $10 million competition designed to fast-track the efforts of solar developers working on community solar projects.
The Inflation Reduction Act already offers incentives to build large solar generation projects, such as renewable energy tax credits. But Ali Zaidi, White House national climate adviser, said the new money focuses on meeting the nation’s climate goals in a way that benefits more communities.
“It’s lifting up our workers and our communities. And that’s, I think, what really excites us about this work,” Zaidi said. “It’s a chance not just to tackle the climate crisis, but to bring economic opportunity to every zip code of America.”
The investments will help people save on their electricity bills and make the electricity grid more reliable, secure, and resilient in the face of a changing climate, said Becca Jones-Albertus, director of the energy department’s Solar Energy Technologies Office.
Jones-Albertus said she’s particularly excited about the support for community solar projects, since half of Americans don’t live in a situation where they can buy their own solar and put in on the roof.
Michael Jung, executive director of the ICF Climate Center agreed. “Community solar can help address equity concerns, as most current rooftop solar panels benefit owners of single-family homes,” he said.
In typical community solar projects, households can invest in or subscribe to part of a larger solar array offsite. “What we’re doing here is trying to unlock the community solar market,” Jones-Albertus said.
The U.S. has 5.3 gigawatts of installed community solar capacity currently, according to the latest estimates. The goal is that by 2025, five million households will have access to it — about three times as many as today — saving $1 billion on their electricity bills, according to Jones-Albertus.
The new funding also highlights investment in a next generation of solar technologies, intended to wring more electricity out of the same amount of solar panels. Currently only about 20% of the sun’s energy is converted to electricity in crystalline silicon solar cells, which is what most solar panels are made of. There has long been hope for higher efficiency, and today’s announcement puts some money towards developing two alternatives: perovskite and cadmium telluride (CdTe) solar cells. Zaidi said this will allow the U.S. to be “the innovation engine that tackles the climate crisis.”
Joshua Rhodes, a scientist at the University of Texas at Austin said the investment in perovskites is good news. They can be produced more cheaply than silicon and are far more tolerant of defects, he said. They can also be built into textured and curved surfaces, which opens up more applications for their use than traditional rigid panels. Most silicon is produced in China and Russia, Rhodes pointed out.
Cadmium telluride solar can be made quickly and at a low cost, but further research is needed to improve how efficient the material is at converting sunlight to electrons.
Cadmium is also toxic and people shouldn’t be exposed to it. Jones-Albertus said that in cadmium telluride solar technology, the compound is encapsulated in glass and additional protective layers.
The new funds will also help recycle solar panels and reuse rare earth elements and materials. “One of the most important ways we can make sure CdTe remains in a safe compound form is ensuring that all solar panels made in the U.S. can be reused or recycled at the end of their life cycle,” Jones-Albertus explained.
Recycling solar panels also reduces the need for mining, which damages landscapes and uses a lot of energy, in part to operate the heavy machinery. Eight of the projects in Thursday’s announcement focus on improving solar panel recycling, for a total of about $10 million.
Clean energy is a fit for every state in the country, the administration said. One solar project in Shungnak, Alaska, was able to eliminate the need to keep making electricity by burning diesel fuel, a method sometimes used in remote communities that is not healthy for people and contributes to climate change.
“Alaska is not a place that folks often think of when they think about solar, but this energy can be an economic and affordable resource in all parts of the country,” said Jones-Albertus.
