Engineers Want To Bring Home the World's Oldest Satellite

2 months 1 week ago
Launched in 1958, the "awkward-looking" Vanguard-1 satellite ("the size of a grapefruit") is the oldest artificial object orbiting Earth. "A team of researchers and engineers want to retrieve the satellite for closer inspection and are currently working to find a way to bring Vanguard-1 home," writes Gizmodo: Other satellites of its time have reentered through Earth's atmosphere, burning up in a fiery death, but Vanguard-1 is still in orbit, silently zooming through the void of space... A team of researchers and engineers from Virginia-based consulting firm Booz Allen Hamilton have put together a proposal on how to retrieve the satellite from space, bringing it back to Earth to study how its equipment has fared over the years, according to a report by Space.com. The team's proposal is detailed in a study published in the Aerospace Research Center earlier this year... Considering how old Vanguard-1 is, the astronauts would need to handle it with care, according to the team behind the proposal. Before a retrieval attempt, the team suggests that a spacecraft be sent to rendezvous with the satellite to inspect its condition up-close. The engineers suggested partnering with a wealthy space enthusiast willing to fund the outer space venture, or using a SpaceX vehicle to bring the satellite home. Once it's brought back to Earth, experts would examine Vanguard-1 to assess its condition — whether it was struck by space debris, if it's still holding together, and how its time in orbit has affected the satellite. The satellite could then be placed at the Smithsonian for display as a sort of time capsule, a reminder of the history of spaceflight, the team suggests. "Future missions (space debris removal, materials capture for on-orbit manufacturing, and even deep space exploration) could build on techniques demonstrated in the retrieval of Vanguard 1," the paper read. "Retrieving Vanguard 1 would be a challenge, but an achievable and invaluable step forward for the entire U.S. space community." "The researchers suggest that the satellite can be placed in a lower orbit and snagged from space, or reeled into the International Space Station," according to the article. Space.com shares this assessment from Bill Raynor, the associate superintendent of the Naval Research Laboratory's spacecraft engineering division. "For material and radiation effects scientists and engineers, it would be an unprecedented opportunity for investigating the effects of long-term space environmental exposure."

Trump-Branded 'Lab Leak' Page Replaces US Covid Information Sites

2 months 1 week ago
"There has never been a consensus or a 'smoking gun' to explain what started the pandemic," writes ABC News. Yet the Associated Press reports that "A federal website that used to feature information on vaccines, testing and treatment for COVID-19 has been transformed into a page supporting the theory that the pandemic originated with a lab leak." (This despite the fact that "about 325 Americans have died from COVID per week on average over the past four weeks, according to the U.S. Centers for Disease Control and Prevention.") The covid.gov website shows a photo of President Donald Trump walking between the words "lab" and "leak" under a White House heading... The web page also accuses Dr. Anthony Fauci, the former director of the National Institute of Allergy and Infectious Diseases, of pushing a "preferred narrative" that COVID-19 originated in nature. The origins of COVID have never been proven. Scientists are unsure whether the virus jumped from an animal, as many other viruses have, or came from a laboratory accident. A U.S. intelligence analysis released in 2023 said there is insufficient evidence to prove either theory. "Many scientists think it's more likely the virus originated naturally in a wild animal and then spilled over into people in a wildlife market located in Wuhan," reports NPR. And even Jamie Metzl, a critic of the wildlife spillover theory, told NPR that while they appreciated "efforts to dig deeper... it would be a terrible shame if such efforts distracted from essential work to help prevent further infections and treat people suffering from COVID-19 and long COVID." (The federal website covidtests.gov now also redirects instead to the new page...) Some scientists were critical of the new site, which they say appears political in intent. "Every one of the five pieces of evidence supporting the lab leak hypothesis ... is factually incorrect, embellished, or presented in a misleading way," [wrote Angela Rasmussen, a virologist at the University of Saskatchewan in Canada]. "But making evidence-based arguments in good faith about the pandemic's origin is not the purpose of this document. This is pure propaganda, intended to justify the systematic devastation of the federal government, particularly programs devoted to public health and biomedical research," Rasmussen added. Other scientists said the web site doesn't follow the existing body of scientific evidence on the issue. That evidence does not support "any of the many, often contradictory, lab leak scenarios that have been proposed," Michael Worobey, an evolutionary biologist at the University of Arizona, in an email to NPR. He argued that the evidence is consistent with "the less flashy hypothesis that bringing live animals infected with pathogens with pandemic potential into the heart of one of the biggest cities in the world was how this pandemic started.... the next pathogen with pandemic potential will find us easy pickings if we don't appreciate how risky this sort of 'biosafety level zero' activity is."

China Pits Humanoid Robots Against Humans In Half-Marathon

2 months 1 week ago
An anonymous reader quotes a report from Reuters: Twenty-one humanoid robots joined thousands of runners at the Yizhuang half-marathon in Beijing on Saturday, the first time these machines have raced alongside humans over a 21-km (13-mile) course. The robots from Chinese manufacturers such as DroidVP and Noetix Robotics came in all shapes and sizes, some shorter than 120 cm (3.9 ft), others as tall as 1.8 m (5.9 ft). One company boasted that its robot looked almost human, with feminine features and the ability to wink and smile. Some firms tested their robots for weeks before the race. Beijing officials have described the event as more akin to a race car competition, given the need for engineering and navigation teams. "The robots are running very well, very stable ... I feel I'm witnessing the evolution of robots and AI," said spectator He Sishu, who works in artificial intelligence. The robots were accompanied by human trainers, some of whom had to physically support the machines during the race. A few of the robots wore running shoes, with one donning boxing gloves and another wearing a red headband with the words "Bound to Win" in Chinese. The winning robot was Tiangong Ultra, from the Beijing Innovation Center of Human Robotics, with a time of 2 hours and 40 minutes. The men's winner of the race had a time of 1 hour and 2 minutes. [...] Some robots, like Tiangong Ultra, completed the race, while others struggled from the beginning. One robot fell at the starting line and lay flat for a few minutes before getting up and taking off. One crashed into a railing after running a few metres, causing its human operator to fall over. You can watch a recording of the race in its entirety on YouTube.
