CAPE CANAVERAL, Florida — The first U.S. spacecraft to land on the moon since the Apollo astronauts fell silent Thursday, a week after breaking a leg at touchdown and tipping over near the lunar south pole.

Intuitive Machines’ lander, Odysseus, lasted longer than the company anticipated after it ended up on its side with hobbled solar power and communication.

The end came as flight controllers received one last photo from Odysseus and commanded its computer and power systems to standby. That way, the lander can wake up in another two to three weeks — if it survives the bitterly cold lunar night.

Intuitive Machines spokesman Josh Marshall said these final steps drained the lander’s batteries and put Odysseus “down for a long nap.”

“Good night, Odie. We hope to hear from you again,” the company said via X, formerly Twitter.

Before losing power, Odysseus sent back what Intuitive Machines called “a fitting farewell transmission.”

Taken just before touchdown, the picture shows the bottom of the lander on the moon’s pockmarked surface, with a tiny crescent Earth and a small sun in the background.

The lander was originally intended to last about a week on the moon.

Houston-based Intuitive Machines became the first private business to land a spacecraft on the moon without crashing when Odysseus touched down February 22. Only five countries had achieved that since the 1960s, including Japan, which made a sideways landing last month.

Odysseus carried six experiments for NASA, which paid $118 million for the ride. The first company to take part in NASA’s program for commercial lunar deliveries never made it to the moon; its lander came crashing back to Earth in January.

NASA views these private landers as scouts that will pave the way for astronauts set to arrive in another few years.

Until Odysseus, the last U.S. moon landing was by Apollo 17’s Gene Cernan and Harrison Schmitt in 1972.

washington — Speaking Mandarin and promoting love for China, countless videos of foreign-looking women made with artificial intelligence started popping up on Chinese social media platforms around the Lunar New Year earlier this month.

The avatars in the videos are created with online images that are stolen, reproduced and repurposed so that even the women in real life recognize themselves in the videos.

Olga Loiek is one of those women. She’s a 20-year-old Ukrainian who studies cognitive science at the University of Pennsylvania. A couple of months ago, Loiek started a YouTube channel where she talks about mental health and shares her philosophies about life.

However, shortly after that, she started receiving messages from followers telling her that they had seen her on Chinese social media. There, she’s not Olga Loiek but a Russian woman who speaks Mandarin, loves China and wants to marry a Chinese man. Her name is Natasha, or Anna, or Grace, depending on the social media platform you find her on in China.

“I started translating the videos with Google Translate, and I realized that most of these accounts are talking about things like China, Russia, how good the relationship between China and Russia is,” she told VOA. “This feels very violating.”

In some videos, the avatars talk about how much they value Russia and China’s close ties. In other videos, they praise Chinese history and culture or talk about how much Russian women want to marry Chinese.

“If you marry Russian women, we will wash clothes, cook, and wash dishes for you every day,” an avatar said. “We will also give you foreign babies, as many as you want.”

Several dozen videos of Loiek’s avatar speaking Mandarin have been found on video sites Douyin and Bilibili. Most of these accounts would ask viewers to visit their online stores to buy what they say are authentic Russian goods.

Douyin, China’s version of TikTok, has labeled some of these videos as potentially AI-generated. But comments show that many believed they were looking at a real woman. One netizen wrote, “Russian beauty, Chinese people welcome you.”

Loiek said she would never say things like that, obviously, given that she’s from Ukraine, which has been at war with Russia since 2022.

She said, “This is probably used to make people, maybe people in China, feel that foreigners feel that their country is superior.”

On Bilibili, China’s biggest video site, some AI videos using Loiek’s face are marked with the logo of HeyGen, indicating that the video was generated on the company’s website.

In one tutorial on Bilibili, the demonstrator even shows how to make a short video on HeyGen with a clip of Loiek talking.

HeyGen is an AI company headquartered in Los Angeles that was launched in China in 2020. It specializes in realistic digital avatars, voice generation and video translating.

The technology developed by HeyGen was used in AI videos of Donald Trump and Taylor Swift speaking perfect Mandarin that went viral on Chinese social media in October 2023. According to Forbes, the company is now valued at $75 million.

HeyGen’s moderation policy states that users cannot generate avatars that “represent real individuals, including celebrities or public figures, without explicit consent.” The company’s official tutorial video on avatar making shows that users must submit a video of people giving consent to the use of their likeness. It’s unclear how some in China could circumvent the requirement to make videos of Loiek.

Loiek said that since she and her YouTube subscribers have sent complaints to Chinese social media companies, about a dozen of the accounts imitating her have been taken down.

VOA reached out to HeyGen and Douyin’s parent company, ByteDance, for comments but has not received a response.

The Chinese government rolled out provisions to regulate deepfakes and other “deep synthesis services” in early 2023. The law prohibits generating deepfakes without the consent of the people whose image or other information is used.

Loiek posted her story on YouTube, and it has been shared on Chinese social media. Netizens across platforms sympathized with her and called for tougher regulations on AI.

Chinese tech giants such as Baidu and Tencent are investing heavily in AI technology. One of the most hyped-up services powered by AI is digital humans.

Tencent and Xiaoice, a Chinese AI studio spun off from Microsoft, offer digital human services that can clone people and turn them into AI avatars for as little as $145.

AI avatars have also been found in online disinformation campaigns that spread pro-China and anti-U.S. narratives. In February 2023, research firm Graphika found a social media campaign promoting Beijing’s interests using realistic-looking computer-generated people in videos.

In September 2023, the U.S. State Department warned in a report, “Access to global data combined with the latest developments in artificial intelligence technology would enable the PRC [People’s Republic of China] to surgically target foreign audiences and thereby perhaps influence economic and security decisions in its favor.

As for Loiek, she does not plan to quit YouTube or stop posting.

“We need some sort of regulatory frameworks, so we can understand and we can prevent these things from happening,” she said.

washington — U.S. President Joe Biden’s is a “healthy, active, robust 81-year-old male who remains fit to successfully execute the duties of the presidency,” his physician, Dr. Kevin O’Connor, said in a statement released by the White House on Wednesday, following Biden’s annual physical examination. 

“The president feels well, and this year’s physical identified no new concerns. He continues to be fit for duty and fully executes all of his responsibilities without any exemptions or accommodations,” O’Connor said following Biden’s visit to Walter Reed National Military Medical Center in Bethesda, Maryland, earlier Wednesday.  

The checkup included consultations with optometry, dentistry, orthopedics, physical therapy, neurology, sleep medicine, cardiology, radiology and dermatology specialists, O’Connor said.  

It’s Biden’s third physical since taking office, amid concerns about his age as he seeks a second term.  

“They think I look too young,” Biden joked to reporters at the White House after his checkup. “There is nothing different than last year,” he said.

According to the summary, Biden is currently being treated for several conditions, including obstructive sleep apnea, gastroesophageal reflux, seasonal allergies, arthritis and sensory peripheral neuropathy of the feet. He also has atrial fibrillation with normal ventricular response, a type of asymptomatic irregularity of the heartbeat.  

His doctor pronounced his conditions as “stable and well-controlled,” with “three common prescription medications and three common over-the-counter medications.”  

The symptoms were similar to those described in Biden’s 2023 physical exam report that noted the president’s “stiff gait,” due to “a combination of significant spinal arthritis, mild post-fracture foot arthritis and a mild sensory peripheral neuropathy of the feet,” and “occasional symptoms of gastroesophageal reflux,” that made him have to clear his throat often.     

President didn’t undergo cognitive test 

Recent events have highlighted Biden’s potential age-related issues, including the president being described in a special counsel report as an “elderly man with a poor memory.”      

In pushing back on reporters’ questions about his age, Biden insisted that his “memory is fine” but shortly after mistakenly referred to Egyptian President Abdel Fattah el-Sissi as the president of Mexico. That and two other mistaken references to world leaders’ names in recent weeks fueled further attacks by his rivals.     

Responding to reporters’ questions during her briefing on Wednesday, White House press secretary Karine Jean-Pierre said Biden did not undergo a cognitive test as part of his physical because the president’s physician, “doesn’t believe that he needs one.” 

As president, Biden passes a cognitive test “every day,” Jean-Pierre underscored. 

A poll by the George Washington University shows 35% of respondents say Biden was in good enough physical health to serve effectively as president, and 38% said he has the mental soundness to serve effectively as president.  

This is lower that what respondents say about the leading candidate for the Republican presidential nomination, Donald Trump, who is four years younger. For Trump, the numbers are 54% and 46%, respectively. 

“These figures indicate that this is a big problem for Biden,” Todd Belt, professor of politics at George Washington University, told VOA. “The campaign has changed course to attack Trump on his vulnerabilities on the mental soundness issue.” 

Biden did exactly that during an appearance on a late-night television show earlier this week, by referencing a video in which Trump appeared to forget his wife’s name.  

Americans concerned about Biden’s age

Trump was 70 when he took office in 2017, which made him the oldest American president to be inaugurated until Biden broke his record at 78 in 2021. The former president has also made blunders, including praising Hungarian Prime Minister Viktor Orban for his leadership of Turkey, and confusing his Republican rival, Nikki Haley, with former U.S. House Speaker Nancy Pelosi.   

A February ABC News/Ipsos poll conducted after the release of the special counsel report indicated concerns among 59% of Americans regarding the age and capability for a second term for both candidates, although more Americans are worried about Biden compared with Trump, said Clifford Young, president of Ipsos Public Affairs.   

“Age is an Achilles’ heel, is an anchor for Biden,” Young told VOA. “It was four years ago. Without a doubt, it will be this year.”   

Though not publicly announced in advance, the timing of Biden’s physical was anticipated, given the increasing focus on his age and health in the context of his reelection campaign ahead of the November election.

new york — Older U.S. adults should roll up their sleeves for another COVID-19 shot, even if they got a booster in the fall, U.S. health officials said Wednesday.

The Centers for Disease Control and Prevention said Americans 65 and older should get another dose of the updated vaccine that became available in September — if at least four months has passed since their last shot. In making the recommendation, the agency endorsed guidance proposed by an expert advisory panel earlier in the day.

“Most COVID-19 deaths and hospitalizations last year were among people 65 years and older. An additional vaccine dose can provide added protection … for those at highest risk,” CDC Director Dr. Mandy Cohen said in a statement.

The advisory panel’s decision came after a lengthy discussion about whether to say older people “may” get the shots or if they “should” do so. That reflects a debate among experts about how necessary another booster is and whether yet another recommendation would add to the public’s growing vaccine fatigue.

Some doctors say most older adults are adequately protected by the fall shot, which built on immunity derived from earlier vaccinations and exposure to the virus itself. And preliminary studies so far have shown no substantial waning in vaccine effectiveness over six months.

However, the body’s vaccine-induced defenses tend to fade over time, and that happens faster in seniors than in other adults. The committee had recommended COVID-19 booster doses for older adults in 2022 and 2023.

Virus still a threat

COVID-19 remains a danger, especially to older people and those with underlying medical conditions. There are still more than 20,000 hospitalizations and more than 2,000 deaths each week due to the coronavirus, according to the CDC. And people 65 and older have the highest hospitalization and death rates.

Some members of the advisory panel said a “should” recommendation is meant to more clearly prod doctors and pharmacists to offer the shots.

Dr. Jamie Loehr, a committee member and family doctor in Ithaca, New York, said that with the “should” recommendation, “I am trying to make it easier for providers to say, ‘Yes, we recommend this.'”

In September, the government recommended a new COVID-19 shot recipe built against a version of the coronavirus called XBB.1.5. That single-target vaccine replaced combination shots that had been targeting both the original coronavirus strain and a much earlier omicron version.

Vaccine uptake has declined

The CDC recommended the new shots for everyone 6 months and older and allowed that people with weak immune systems could get a second dose as early as two months after the first.

Most Americans haven’t listened. According to the latest CDC data, 13% of U.S. children have gotten the shots and about 22% of U.S. adults have. The vaccination rate is higher for adults 65 and older, at nearly 42%.

“In each successive vaccine, the uptake has gone down,” said Dr. David Canaday, a Case Western Reserve University infectious-diseases expert who studies COVID-19 in older people.

“People are tired of getting all these shots all the time,” said Canaday, who does not serve on the committee. “We have to be careful about over-recommending the vaccine.”

But there is a subset of Americans — those at higher danger of severe illness and death — who have been asking if another dose is permissible, said Dr. William Schaffner, a Vanderbilt University vaccines expert who serves on a committee workgroup that has been debating the booster question.

Indeed, CDC survey data suggest that group’s biggest worry about the vaccine is whether it’s effective enough.

Agency officials say that among those who got the latest version of the COVID-19 vaccine, 50% fewer will get sick after they come into contact with the virus compared with those who didn’t get the fall shot.

washington — Rights advocates are urging international social media platforms to do more to prevent Chinese authorities from obtaining the personal information of users. The call comes after two popular Chinese social media influencers alleged on X and YouTube that police in China were investigating their followers and had called some in for questioning.

Social media platforms such as X and YouTube and thousands of websites — from The New York Times to the BBC and VOA — are blocked in China by the country’s Great Firewall. But increasingly, even as social controls tighten under the leadership of Xi Jinping, many in China are using virtual private networks to access X, YouTube and other sites for news, information and opinions not available in China.

Li Ying, who is also known online as Teacher Li, is one of the social media influencers who issued the warning on Sunday. Li came to prominence as a source of news and information following a rare display of public dissent in 2022 in China, protesting the government’s draconian zero-COVID policy. His account on X has now become a hub for news and videos provided by netizens that the Chinese government considers sensitive and censors online.

In a post on Sunday, Teacher Li said, “Currently, the public security bureau is checking my 1.6 million followers and people in the comments, one by one.”

He shared screenshots of private messages he received from followers over the past few months, some of which claimed that police had interrogated individuals, even causing one person to lose their job.

VOA could not independently verify the authenticity of the claims, but court records in China and reports by rights groups have previously documented the country’s increasing use of social media platforms banned in China to detain, prosecute and sentence individuals over comments made online.

The Chinese Embassy spokesperson in Washington, Liu Pengyu, said he was not aware of the specifics regarding the social media influencers.

“As a principle, the Chinese government manages internet-related affairs according to law and regulation,” Liu said.

Influencers warn followers

News of the crackdown on followers of social influencers comes amid a flurry of reports about China’s hacking capabilities. Last week, FBI Director Christopher Wray warned that cyberattacks on U.S. infrastructure were “at a scale greater than we’d seen before.”

A recent document dump detailed how private companies are helping China to hack foreign governments across Southeast Asia and to unmask users of foreign social media accounts.

Wang Zhi’an, a former journalist at China’s state broadcaster CCTV who has a million subscribers on X and 1.2 million followers on YouTube, says his followers have reported similar problems.

In response, both Wang and Teacher Li have urged their followers to take precautions, suggesting they unfollow their accounts, change their usernames, avoid Chinese-made phones and prepare to be questioned.

As of Tuesday afternoon, Li’s followers on X had dropped to 1.4 million. VOA reached out to Li for comment but did not receive a response as of publication.

Authorities reportedly tracking followers

Maya Wang, acting China director at Human Rights Watch, said China is putting more effort into policing platforms based outside of the country as more Chinese people move to the platforms to speak out.

She said the recent reports of authorities tracking down followers is just a part of China’s long-standing effort to restrict freedom of expression.

“I think the Chinese government is also increasingly worried about the information that is being propagated, transmitted or distributed on these foreign platforms because they have been, thanks to these individuals, very influential,” Wang said.

A recent leak of documents from I-Soon, a private contractor linked to China’s top policing agency and other parts of its government, described tools used by Chinese police to curb dissent on overseas social media, including one tool specifically created to surveil users on X.

Hackers also created tools for police to hack email inboxes and unmask anonymous users of X, the documents show. The leak revealed that officers sometimes sent requests to surveil specific individuals to I-Soon.

Wang said it is incumbent on social media companies to make sure their users stay safe.

“I would want to direct these questions to Twitter [X] to ask — are they adopting heightened measures to protect PRC [People’s Republic of China]-based users?” she said. “I think Twitter [X] needs to investigate just how exactly this kind of information is being obtained and whether or not they need to plug some loopholes.”

Yaqiu Wang, research director for China, Hong Kong and Taiwan at Freedom House, said that besides better protecting their users’ privacy, the companies should also put in more effort to combat China’s clampdown on freedom of speech.

“They should have steps actually helping out activists to protect their freedom of speech,” she said. “Big social media companies should widely disseminate information to their users, like a manual or instructions of how to protect their account.

“They need to be more transparent, so users and the public know whether government-sponsored hacking activities are going on,” she added.

VOA reached out to X, formerly known as Twitter, several times for comment but did not receive any response by the time of publication.

STATE DEPARTMENT — With a science and technology agreement between the United States and People’s Republic of China due to expire Tuesday, the State Department said it is negotiating to “amend, extend, and strengthen protections within” the agreement but declined to specify if the U.S. would extend the deal.

“We are not able to provide information at this time on specific U.S. negotiating positions or on whether the agreement will be extended past its current expiration date,” a State Department spokesperson told VOA.

The Science and Technology Cooperation Agreement is a framework for U.S. governmental collaborations with China in science and technology.  

U.S. officials have said the STA provides consistent standards for government-to-government scientific cooperation between the U.S. and China.  

While the agreement supports scientific collaboration in areas that benefit the United States, U.S. officials acknowledge the challenges posed by China’s national science and technology strategies and its domestic legal framework.

Critics, including U.S. lawmakers, point out China’s restrictions on data and a lack of transparency in sharing scientific findings. Washington is also concerned about personal safety of American scientists who travel to China, as well as Beijing’s potential military application of shared research.

A report by Congressional Research Service said China’s cooperation under the agreement has not been consistent. For example, “China reportedly withheld avian influenza strains required for U.S. vaccines and in 2019, cut off U.S. access to coronavirus research, including U.S.-funded work at the Wuhan Institute of Virology,” said the CRS.

Advocates for renewing the agreement want to maintain some level of official and unofficial contacts amid strained relationship between the two countries.  

During a recent discussion hosted by the Washington-based Institute for China-America Studies (ICAS), panelists said the STA is “important symbolically” and gives confidence to researchers on both sides to deepen their engagement with counterparts.

“In the event of the agreement’s non-renewal, the mutual confidence that sustains and underpins collaboration is bound to suffer,” said ICAS in its post-event summary.

Dean Cheng, a senior advisor to the China program at the U.S. Institute of Peace, said the American system is far more open, so China will typically be able to gather information regardless of whether there is an agreement.

“The STA is no guarantee that American scientists will, in fact, be able to access Chinese research, information, or scholars, whereas the Chinese side will use the STA as a means of establishing an even greater presence in the U.S.,” Cheng told VOA, adding the “strategic advantage” under the deal will likely be with the PRC.

The STA was originally signed in 1979 by then-U.S. President Jimmy Carter and then-PRC leader Deng Xiaoping. Under the agreement, the two countries cooperate in fields including agriculture, energy, space, health, environment, earth sciences and engineering, as well as educational and scholarly exchanges.

U.S.-China science and technology activity increased in November 2009 with new agreements on joint projects in electric vehicles, or EVs, renewable energy, and the creation of the U.S.-China Clean Energy Research Center, or CERC, a 10-year research effort between the U.S. Department of Energy and China’s Ministry of Science and Technology.

The agreement has been renewed approximately every five years since its inception, with the most recent five-year extension occurring in 2018. Last August, it received a six-month extension as officials from the two countries undertook negotiations to amend and strengthen the terms.

SHANGHAI — Two prominent Chinese bloggers in exile said that police were investigating their millions of followers on international social media platforms, in an escalation of Beijing’s attempts to clamp down on critical speech even outside of the country’s borders.

Former state broadcaster CCTV journalist Wang Zhi’an and artist-turned-dissident Li Ying, both Chinese citizens known for posting uncensored Chinese news, said in separate posts Sunday that police were interrogating people who followed them on social media, and urged followers to take precautions such as unfollowing their accounts, changing their usernames, avoiding Chinese-made phones and preparing to be questioned.

Li Ying, known as Teacher Li, came to prominence as a source of news about the White Paper protests, a rare moment of anti-government protests in mainland China in 2022. Teacher Li’s account on X, formerly known as Twitter, @whyyoutouzhele now posts news and videos submitted by users, which cover everything from local protests to viral videos of real-life incidents that are censored on the Chinese internet.

In a post Sunday evening, Teacher Li suggested people unfollow his account. “Currently, the public security bureau is checking my 1.6 million followers and people in the comments, one by one.”

Li shared screenshots of private messages he received from followers over the past few months, which claimed that police had interrogated individuals, and that one person had even lost their job.

As of Monday afternoon, Li had dropped down to 1.4 million followers on X.

International social media platforms like X and YouTube are blocked in China but can still be accessed with software that circumvents the country’s censorship systems.

Wang, who has a million subscribers on X and 1.2 million followers on YouTube, also told his fans to unsubscribe.

Li, Wang and the Chinese foreign ministry did not immediately respond to requests for comment.

Over the past decade, Beijing has cracked down on dissent on Chinese social media, with thousands of censors employed both at private companies and with the Chinese state.

Chinese users expressing critical opinions online have reported being called, harassed or interrogated by police, with some called in for questioning and ordered to take down certain posts or delete their accounts. In some cases, users have been detained, with some spending up to two weeks in jail and a small number sentenced to years in prison.

More recently, Beijing has extended its reach to tracking non-Chinese platforms such as Facebook, Telegram and X. A recent leak of documents from I-Soon, a private contractor linked to China’s top policing agency and other parts of its government, described tools used by Chinese police to curb dissent on overseas social media, including one tool specifically created to surveil users on X.

Hackers also created tools for police to hack email inboxes and unmask anonymous users of X, the documents show. Sometimes, officers sent requests to surveil specific individuals to I-Soon, the leak revealed.

Li said he would not stop posting even if people unfollowed, but he urged his followers to take basic digital safety precautions.

“I don’t want your life to be impacted just because you wanted to understand the real news in China,” Li said, in an additional post. “You only want to understand what’s happening, but the price is quite high
