vm shares a report from Space.com: SpaceX is among companies that might replace services of NASA's aging space telecoms constellation that has kept the International Space Station connected to Earth for decades. For years, NASA's Tracking and Data Relay Satellite (TDRS) constellation has served as the main link between the International Space Station and Earth, providing astronauts with constant connection to ground control as well as the ability to engage with the public and stay in touch with their loved ones. The American space agency, however, plans to retire the six aging satellites in the next decade and hand over their task to commercial companies. This month, the agency announced partnerships with six commercial satellite operators including SpaceX, U.K. company Inmarsat, American Viasat and Switzerland-based SES, to demonstrate how they could take care of NASA's space communication needs in the future. "We don't plan to launch any new TDRS satellites in the future," Eli Naffah, the manager of NASA's Commercial Services Project, who oversees the partnership with the commercial companies, told Space.com. "The plan is to allow the constellation to basically [reach the end of its life]. At some point later in this decade, we are going to have some diminished capability and the plan is for the [commercial companies] to come up with a different way of providing communication services to our missions."

"Back in the 1980s, when we developed TDRS, there really wasn't an ability on the commercial side to be able to provide this service," Naffah said. "But since then, the industry has far outpaced NASA's investment in this area. There's a lot of infrastructure, both on the ground and in orbit that is capable of providing these types of services to a spacecraft. [...] Hopefully, we can achieve some cost efficiencies in buying commercial services, get out of the business of operating networks, and really put more focus on science and exploration." According to Naffah, NASA will invest $278 million into the project over the next five years, with the agency's industry partners contributing a total of about $1.5 billion.

The common perception that nearly everyone in America seemed to have acquired the Omicron variant last winter may not have been far from the truth. By February 2022, nearly 60 percent of the population had been infected with the coronavirus, almost double the proportion seen in December 2021, according to data released on Tuesday by the Centers for Disease Control and Prevention. The New York Times reports: "By February 2022, evidence of previous Covid-19 infections substantially increased among every age group," Dr. Kristie Clarke, the agency researcher who led the study, said at a news briefing. Infections rose most sharply during the Omicron surge among children and adolescents, perhaps because many people in those age groups were still unvaccinated. The increase was smallest among adults 65 or older, who have the highest rate of vaccination and may be the most likely to take precautions. The new research suggests that three out of four children and adolescents in the United States had been infected with the coronavirus by February 2022, compared with one-third of older adults.

While some studies suggest that prior infection offers a weaker shield against the virus than vaccines do, the resulting antibodies should provide a reasonable degree of protection against severe illness, at least in the short term. "We still do not know how long infection-induced immunity will last," Dr. Clarke said. The gains in population-wide immunity may explain why the new surge that is roaring through China and many countries in Europe has been muted in the United States so far. The findings may offer some comfort to parents who have been waiting anxiously for a vaccine to be approved for the youngest children. Many of those children now seem to have acquired at least some immunity. Even so, Dr. Clarke urged parents to immunize children who qualify as soon as regulators approve a vaccine for them, regardless of any prior infection.

A group of TikTok- and Instagram-famous physicians say they have a solution for the "red tape" of the current medical system: NFTs of cartoon doctors. From a report: These NFTs, called MetaDocs, are supposed to give buyers access to real doctors, almost like a Web3 telehealth subscription. When MetaDocs launched in December, it claimed that its legion of celebrity doctors, who have a collective social media following of 70 million and have included "Dr. Pimple Popper" Sandra Lee and plastic surgeon Dr. Richard Brown of TikTok fame, would all be available via DM, group "ask me anything" sessions, or one-on-one video chats to those who buy in. MetaDocs founder Dr. Sina Joorabchi hopes it will evolve into a full-fledged virtual clinic in the so-called metaverse, where patients can put on a haptic suit and be examined remotely by a physician in virtual reality.

But now, MetaDocs is facing backlash from the medical community, in part because it is not actually licensed as a telemedicine service and thus its doctors cannot legally make diagnoses, write prescriptions, or give personalized medical advice to anyone who buys a MetaDocs NFT. A further wrinkle: Doctors are almost always required to be licensed in a state in order to practice there, including through telehealth services. "At this point, we're hesitant to refer to anybody as a patient," Dr. Dustin Portela, a MetaDocs physician and practicing dermatologist, told BuzzFeed News. According to a recent white paper, the presale cost of a MetaDocs NFT will be 0.2 ETH, or about $570, though the company hasn't determined an exact price yet. But why would someone pay hundreds of dollars for a cartoon so they could "ask a doctor anything" if they are not seeking some form of medical advice?

The seismometer placed on Mars by NASA's InSight lander has recorded its two largest seismic events to date: a magnitude 4.2 and a magnitude 4.1 marsquake. Phys.Org reports: The pair are the first recorded events to occur on the planet's far side from the lander and are five times stronger than the previous largest event recorded. Seismic wave data from the events could help researchers learn more about the interior layers of Mars, particularly its core-mantle boundary, researchers from InSight's Marsquake Service (MQS) report in The Seismic Record.

Anna Horleston of the University of Bristol and colleagues were able to identify reflected PP and SS waves from the magnitude 4.2 event, called S0976a, and locate its origin in the Valles Marineris, a massive canyon network that is one of Mars' most distinguishing geological features and one of the largest graben systems in the Solar System. Earlier orbital images of cross-cutting faults and landslides suggested the area would be seismically active, but the new event is the first confirmed seismic activity there.

S1000a, the magnitude 4.1 event recorded 24 days later, was characterized by reflected PP and SS waves as well as Pdiff waves, small amplitude waves that have traversed the core-mantle boundary. This is the first time Pdiff waves have been spotted by the InSight mission. The researchers could not definitively pinpoint S1000a's location, but like S0976a it originated on Mars' far side. The seismic energy from S1000a also holds the distinction of being the longest recorded on Mars, lasting 94 minutes.

An anonymous reader quotes a report from the Guardian: Scientific experiments on crabs and lobsters could be curbed when the animal sentience bill becomes law, the Guardian has learned. There are few restrictions on how crustaceans and decapods can be treated in scientific studies, in contrast with mice and other mammals, for which there are strict welfare laws. Because scientists do not have to register how many crustaceans and decapods they experiment on, there are no numbers for how many are used. But because they breed quickly and are sensitive to pollutants, they are frequently used in experiments, especially those that look into how different types of pollution affect the body. But this could be about to change, Home Office sources said after crabs and lobsters were recognized as sentient beings which could feel pain.

The new legislation, which is awaiting royal consent after being approved by parliament this month, means ministers must consider the sentience of animals when implementing policy. This could result in restrictions on how crabs and lobsters can be treated when experimented on. They are not included in the Animals (Scientific Procedures) Act 1986, unlike mice, octopuses and various other animals. This means that no licenses or training are required before they can be used in procedures that can cause pain, suffering or distress.

Robert Ellwood, professor emeritus at the school of biological science at Queen's University Belfast, authored the research that found crabs and lobsters feel pain. He welcomed the potential legislative development, but said it must be applied to the commercial fishing industry as well as scientists. "This is a step forward and if people are happy to accept that decapods are sentient and experience pain, then they should be given some protection. But I would see this ... as a problem if they still leave millions of animals in commercial practices that are treated the same as before," said Ellwood, who has worked with crustaceans for 30 years. He added: "To ask scientists to go through all sorts of regulations that affect their work but allow these animals to be boiled alive at will would be unfair. "It is asking for more rules, regulations and red tape, it will take longer to conduct an experiment, but that is a good thing, if it is applied across the board."

The global effort to protect Earth from dangerous asteroids is set to become stronger, as China has announced its intentions to test an asteroid redirect system as early as 2025. Reader InfiniteZero writes: Speaking to China Central Television on Sunday, Wu Yanhua, deputy head of the China National Space Administration (CNSA), described China's preliminary plans to embark on the planetary defense project, according to Chinese state-owned news agency Global Times. Wu's comments coincided with Space Day, an annual event that commemorates the 1970 launch of China's first satellite, Dongfanghong-1, in 1970. For the proposed test, Wu said a probe would closely survey a near-Earth object prior to smashing into it. Known as kinetic impaction, the idea is to alter the orbital trajectory of a threatening asteroid by directing a large, high-speed spacecraft into the object. NASA is currently running a similar test, known as the Double Asteroid Redirection Test, or DART, which seeks to deliberately crash a space probe into Dimorphos -- a tiny asteroid -- later this year.

Long-time Slashdot reader drinkypoo writes: Researchers at UNSW Sydney have discovered that aphantasia, or lack of visual imagination, can be detected by lack of pupillary response. Pupillary response to both real and imagined objects was measured and compared, and the response to imagined objects was larger in those reporting greater vividness of imagery.
"One of the problems with many existing methods to measure imagery is that they are subjective, that is to say they rely on people being able to accurately assess their own imagery," says Professor Joel Pearson, senior author of the paper. "Our results show an exciting new objective method to measure visual imagery, and the first physiological evidence of aphantasia. With over 1.3 million Australians thought to have aphantasia, and 400 million more internationally, we are now close to an objective physiological test, like a blood test, to see if someone truly has it... We are very close to having objective, reliable tests for extreme imagery, aphantasia and hyperphantasia (extremely strong visual imagery) that could be scaled up to run online for millions of people everywhere,"

Another author on the study sees a larger significance. "These findings further highlight the wide variability of the human mind that can often remain hidden until we ask someone about their internal experiences or invent new ways to measure the mind. It reminds us that just because I remember or visualise something one way, doesn't mean everyone does."

Bill Gates shares a statistic about the COVID-19 pandemic. "If we'd been able to stop it within 100 days, we would've saved over 98% of the lives." "Viruses spread exponentially, and so if you get in there when the infection rate is fairly small, you can actually stop the spread."
In a new TED talk, Gates argues that we did learn a lot from this pandemic — enough to build a prevention system for next time. "Covid 19 can be the last pandemic if we take the right steps." But the answer isn't vaccines. "We also need vaccines, but we want to stop the outbreak before we have to do a global vaccination campaign." And then Gates points out that currently it could take months to get resources to a low-income country experiencing an outbreak.

Read on for Slashdot's report on Gates' proposed solution — and how he feels about his own prominence in anti-vaccine misinformation.

Once every 10 years there's a report released by America's National Academies of Sciences, Engineering, and Medicine.

Released this year, the report recommends prioritizing a mission to the planet Uranus to map its gravitational and magnetic fields and study how the planet's internal heat moves to the surface.

BGR reports: Despite being the seventh planet in our solar system, there's very little we know about Uranus as a whole. In fact, one of the best images we have of the planet was captured in 1986 by the Voyager 2... Additionally, scientists want to learn more about the various moons that surround the planet. We also know very little about the ring system that surrounds the blue planet. A team led by Mark Hofstadter, a planetary scientist with NASA's Jet Propulsion Lab wrote a white paper on their goals....

We currently already have the tech we need to get a spacecraft there that can orbit the planet. Additionally, scientists have found that launching a mission in 2031 would allow us to capitalize on gravity assistance from Jupiter.
The report also recommends studying Enceladus, an icy moon orbiting Saturn which has shown signs it could sustain microbial life.

After startup Axiom Space brokered the first visit to the Space Station by an all-private crew, the AX-1 mission turned into a "longer-than-expected" stay, reports CNN. It launched on April 8 and "was originally billed as a 10-day mission," CNN notes, "but delays have extended the mission by about a week." The four crew members — Michael López-Alegría, a former NASA astronaut-turned-Axiom employee who is commanding the mission; Israeli businessman Eytan Stibbe; Canadian investor Mark Pathy; and Ohio-based real estate magnate Larry Connor — are slated to leave the space station aboard their SpaceX Crew Dragon capsule on Sunday at 8:55 pm ET. That's another 24-hour delay from what NASA and Axiom were targeting on Saturday. They now plan to spend a day free flying through orbit before plummeting back into the atmosphere and parachuting to a splashdown landing off the coast of Florida at about 1 pm ET Monday, according to a tweet from Kathy Lueders, the head of NASA's human spaceflight program...

During their first 12 days on the space station, the group stuck to a regimented schedule, which included about 14 hours per day of activities, including scientific research that was designed by various research hospitals, universities, tech companies and more. They also spent time doing outreach events by video conferencing with children and students. The weather delays then afforded to them "a bit more time to absorb the remarkable views of the blue planet and review the vast amount of work that was successfully completed during the mission," according to Axiom....

It's not the first time paying customers or otherwise non-astronauts have visited the ISS, as Russia has sold seats on its Soyuz spacecraft to various wealthy thrill seekers in years past. But AX-1 is the first mission with a crew entirely comprised of private citizens with no active members of a government astronaut corps accompanying them in the capsule during the trip to and from the ISS. It's also the first time private citizens have traveled to the ISS on a US-made spacecraft.

Analysis of thousands of tumours has unveiled a treasure trove of clues about the causes of cancer, representing a significant step towards the personalisation of treatment. The Guardian: Researchers say that for the first time it is possible to detect patterns -- called mutational signatures -- in the DNA of cancers. These provide clues including about whether a patient has had past exposure to environmental causes of cancer such as smoking or UV light, for example. This is important as these signatures allow doctors to look at each patient's tumour and match it to specific treatments and medications. However, these patterns can be detected only through analysis of the vast amounts of data unearthed by whole genome sequencing -- identifying the genetic makeup of a cell.

Deep underneath the Alps, on the Swiss-French border, something significant just happened in the world of physics. The Large Hadron Collider, Earth's most powerful particle accelerator, was restarted on Friday morning after a three-year hiatus for upgrades. From a report: Consisting of a ring 27 kilometers (16.7 miles) in circumference, the machine is made of superconducting magnets chilled to 271.3C (-456 F) -- which is colder than outer space. It works by smashing tiny particles together to allow scientists to observe them, and to see what's inside. It may sound like the stuff of science fiction, but the revamped collider will ultimately allow mankind to observe dark matter, physicists hope. Back in 2011 the Large Hadron Collider, located 100 meters underground at the European Organization for Nuclear Research (CERN), helped scientists prove the existence of an subatomic particle called the Higgs boson -- which is thought to be a fundamental building block of the universe dating back to the Big Bang billions of years ago.

CERN said on its website that the collider magnets "squeeze" tiny particles causing them to crash together, which scientists then observe. These particles are so tiny, CERN said, that lining them up to smash together is "akin to firing two needles 10 kilometers apart with such precision that they meet halfway." Improvements to the collider mean scientists will be able to study the Higgs boson in "great detail," CERN said in a press release Friday. Now a team of experts hope to be able to collide yet more particles together with the aim of understanding the mysteries of dark matter -- an invisible and elusive mass that can't be seen because it doesn't absorb, reflect or emit any light.

China's largest city has recorded just 17 Covid deaths, despite surging cases. How China defines a Covid death may be part of the reason. The New York Times: By the numbers, Shanghai has been an exemplar of how to save lives during a pandemic. Despite the city's more than 400,000 Covid-19 infections, just 17 people have died, according to officials, statistics they have touted as proof that their strategy of strict lockdowns and mass quarantines works. But those numbers may not give a complete picture of the outbreak's toll. China typically classifies Covid-related deaths more narrowly than many other countries, labeling some chronically ill patients who die while infected as victims of those other conditions. In addition, a nearly three-week lockdown of China's biggest city has limited access to medicine and care for other illnesses. A nurse who suffered an asthma attack died after being denied care because of virus controls. A 90-year-old man died of complications from diabetes after being turned away from an overwhelmed hospital.

"If, at the time, he had been able to get treatment, he probably would have survived," said the man's granddaughter, Tracy Tang, a 32-year-old marketing manager. Residents and frontline workers have also been pushed to their limits by the policies. A hospital worker started bleeding internally after long hours conducting mass testing; she, too, died. It may never become clear how many similar stories there are. China does not release information on excess deaths, defined as the number of deaths -- from Covid as well as other causes -- exceeding the expected total in a given period. Public health scholars say that figure more accurately captures losses during the pandemic, as countries define Covid-related deaths differently. But as an example of the hidden impacts, a prominent Chinese physician recently estimated that nearly 1,000 more diabetes patients could die than expected during Shanghai's lockdown, urging the authorities to take a more measured response.

The outbreak there has revived questions about the true toll of Covid in China, which has officially reported fewer than 5,000 deaths from the coronavirus in two years. Beijing is unlikely to waver from its stringent approach. China's leader, Xi Jinping, has made the country's low death and infection rates central to his administration's legitimacy. Officials have been fired after even a few cases were detected in their jurisdictions. Last week, Mr. Xi said that "prevention and control work cannot be relaxed." The focus on minimizing Covid deaths risks incentivizing officials to neglect other causes of death, said Xi Chen, a professor of public health at Yale.

Shallow liquid water may be present on Jupiter's moon Europa, data based on the Greenland ice sheet suggests. The Independent reports: Europa is a prime candidate for life in the Solar System, and its deep saltwater ocean has captivated scientists for decades. The giant planet's moon has been visited by the Voyager and Galileo spacecrafts, and data collected on these missions, together with modeling, indicates the potential presence of a liquid water ocean beneath a 20-30km thick ice shell. While the thickness of the icy shell makes sampling it a daunting prospect, increasing evidence reveals the ice shell may be less of a barrier and more of a dynamic system -- and potentially good enough to support life in its own right.

Observations that captured the formation of a double ridge feature in Greenland suggest the ice shell of Europa may have an abundance of water pockets beneath similar features that are common on the surface. Study senior author Dustin Schroeder, an associate professor of geophysics at Stanford University's School of Earth, Energy & Environmental Sciences (Stanford Earth), said: "Because it's closer to the surface, where you get interesting chemicals from space, other moons and the volcanoes of Io, there's a possibility that life has a shot if there are pockets of water in the shell. If the mechanism we see in Greenland is how these things happen on Europa, it suggests there's water everywhere."

Double ridges on Europa appear as dramatic gashes across the moon's icy surface, with crests reaching nearly 1,000 feet. Study author Riley Culberg, a PhD student in electrical engineering at Stanford, said: "In Greenland, this double ridge formed in a place where water from surface lakes and streams frequently drains into the near-surface and refreezes. One way that similar shallow water pockets could form on Europa might be through water from the subsurface ocean being forced up into the ice shell through fractures -- and that would suggest there could be a reasonable amount of exchange happening inside of the ice shell." The researchers describe their findings in the journal Nature Communications.

An anonymous reader quotes a report from Gizmodo: A team of mechanical engineers at MIT recently developed an "Oreometer" to test the optimal way of separating the two halves of an Oreo cookie, so that the wafers and the creme filling inside remained unbroken. It was an exercise in rheology, or the study of how matter flows. (They called this particular experiment "Oreology.") The fluid in this case was the creme filling, a soft solid that the team classified as "mushy," meaning it's not very brittle (unlike a cracker) and is relatively soft (like bread). The team built their Oreometer to test how different types of Oreos separate, paying particular attention to the creme distribution across the two wafers once the cookie split. Their research is published today in Physics of Fluids.

"Our favorite twist was rotating while pulling Oreos apart from one side, as a kind of peel-and-twist, which was the most reliable for getting a very clean break," said Crystal Owens, a mechanical engineer at MIT and the lead author of the new paper, in an email to Gizmodo. "Peeling is intuitively well-known to cause adhesive failure, like when you want to remove a sticker from a surface without tearing the sticker itself." [...] The researchers found that the creme would often stay on one side of the wafers ("Wafer 1") rather than the other, which they believe is a result of how the Oreos are manufactured. They tested regular Oreos as well as the Double and Mega Stuf varieties, which have more creme filling, and didn't report any apparent correlation between the amount of creme and how cleanly the cookie separated. The team made the Oreometer design open source, so anyone can build their own device and collect data on Oreo separation and shear. Fry would be proud.

The United States government has committed to ending the practice of anti-satellite missile tests, Vice President Kamala Harris announced on Monday, urging other nations to follow its lead. From a report: An anti-satellite weapons, or ASAT, test is a military demonstration in which a spacecraft in orbit is destroyed using a missile system. Countries performing ASAT tests historically have done so by targeting their own assets in space. Plans for the move were set late last year, after the Russian military destroyed a defunct satellite with an ASAT on Nov. 15. The Russian test created thousands of pieces of debris in low Earth orbit, and sent astronauts on the International Space Station into shelter as it passed through the shrapnel field.

During Harris' first meeting in December as chair of the National Space Council, the vice president directed the group to work with other agencies and create proposals that would establish new national security norms in space. The U.S. ASAT commitment, which coincides with Harris' tour of Vandenberg Space Force Base in California on Tuesday, marks the first step of that effort. The White House stressed that "the United States is the first nation to make such a declaration" to end such testing.

In 2021, a team of hologram doctors was "holoported" to space to visit astronauts living aboard the International Space Station, NASA has revealed in a new post. Space.com reports: The hologram teams, led by NASA flight surgeon Dr. Josef Schmid and Fernando De La Pena Llaca, CEO of software provider Aexa Aerospace, were the first humans to ever be "holoported" from Earth to space. "This is completely new manner of human communication across vast distances," Schmid said in the statement. "Furthermore, it is a brand-new way of human exploration, where our human entity is able to travel off the planet. Our physical body is not there, but our human entity absolutely is there."

"It doesn't matter that the space station is traveling 17,500 mph [28,000 kilometers per hour] and in constant motion in orbit 250 miles [400 km] above Earth, the astronaut can come back three minutes or three weeks later and with the system running, we will be there in that spot, live on the space station," Schmid added. The medical teams holoported to the station on Oct. 8. Using the Microsoft Hololens Kinect camera and a personal computer with custom Aexa software, European Space Agency astronaut Thomas Pesquet, who was on board the station at that time, had a holo-conversation with Schmid and De La Pena's teams. The holograms of the doctors were visible live in the middle of the space station.

So how did it work? The "holoportation" technology that enabled this event works using specialized image capture technology that reconstructs, compresses and transmits live 3D models of people. This technology couples with the HoloLens, a self-described "mixed reality headset" that combines sensors, optics and holographic processing tech to allow the wearer to see the hologram images or even enter a "virtual world." With the two systems combined, users in orbit can not only see hologram participants, but can also hear and interact with them. The technology is not new, but has never been used in an environment this challenging with users so far apart.

An anonymous reader quotes a report from IEEE Spectrum: The longest journey begins with a single step, and that step gets expensive when you're in the space business. Take, for example, the Electron booster made by Rocket Lab, a company with two launch pads on the New Zealand coast and another awaiting use in Virginia. [...] If all goes well, its next flight, currently targeted for 22 April, will carry 34 commercial satellites -- and instead of being dropped in the Pacific, the spent first stage will be snared in midair by a helicopter as it descends by parachute. The helicopter will then fly it back to base, seared by the heat of reentry but inwardly intact, for possible refurbishment and reuse.

"It's a very complex thing to do," says Morgan Bailey of Rocket Lab. "You have to position the helicopter in exactly the right spot, you have to know exactly where the stage is going to be coming down, you have to be able to slow it enough," she says. "We've practiced and practiced all of the individual puzzle pieces, and now it's putting them together. It's not a foregone conclusion that the first capture attempt will be a success." Still, people in the space business will be watching, since Rocket Lab has established a niche for itself as a viable space company. This will be its 26th Electron launch. The company says it has launched 112 satellites so far, many of them so-called smallsats that are relatively inexpensive to fly. "Right now, there are two companies taking payloads to orbit: SpaceX and Rocket Lab," says Chad Anderson, CEO of Space Capital, a firm that funds space startups.

Beacon of Galaxy message could be sent into heart of Milky Way, where life is deemed most likely to exist. From a report: "Even if the aliens are short, dour and sexually obsessed," the late cosmologist Carl Sagan once mused, "if they're here, I want to know about them." Driven by the same mindset, a Nasa-led team of international scientists has developed a new message that it proposes to beam across the galaxy in the hope of making first contact with intelligent extraterrestrials. The interstellar missive, known as the Beacon in the Galaxy, opens with simple principles for communication, some basic concepts in maths and physics, the constituents of DNA, and closes with information about humans, the Earth, and a return address should any distant recipients be minded to reply.

The group of researchers, headed by Dr Jonathan Jiang at Nasa's Jet Propulsion Laboratory in California, says that with technical upgrades the binary message could be broadcast into the heart of the Milky Way by the Seti Institute's Allen Telescope Array in California and the 500-metre Aperture Spherical Radio Telescope in China. In a preliminary paper, which has not been peer reviewed, the scientists recommend sending the message to a dense ring of stars near the centre of the Milky Way -- a region deemed most promising for life to have emerged.

"Humanity has, we contend, a compelling story to share and the desire to know of others -- and now has the means to do so," the scientists write. The message, if it ever leaves Earth, would not be the first. The Beacon in the Galaxy is loosely based on the Arecibo message sent in 1974 from an observatory of the same name in Puerto Rico. That targeted a cluster of stars about 25,000 light years away, so it will not arrive any time soon. Since then, a host of messages have been beamed into the heavens including an advert for Doritos and an invitation, written in Klingon, to a Klingon Opera in The Hague.

Three Chinese astronauts, also known as taikonauts, safely returned to Earth yesterday after spending six months aboard China's unfinished Tiangong space station, according to a report from Space.com. This is China's second crewed mission to Tiangong and its longest so far. From a report: The Shenzhou 13 spacecraft landed in the Inner Mongolia desert at 9:56AM local time on Saturday morning after departing from the space station's core Tianhe module about nine hours prior. The crew took off from the Jiuquan Satellite Launch Center in the Gobi desert last October and spent a total of 183 days on the space station. This mission is China's longest.

In addition, taikonaut Wang Yaping made history as the first Chinese woman to visit the Tianhe space station and also became the first Chinese woman to conduct a spacewalk. Wang was accompanied by crewmate Ye Guangfu and commander Zhai Zhigang. The trio carried out a total of two spacewalks, performed various tests around the station, and held two live lectures for students watching from Earth. Shenzhou 13 is part of 11 missions China has planned to finish constructing the Tiangong space station. China first launched the Tianhe module in April 2021 and later sent three taikonauts to bring the station online. As noted by Space.com, the Shenzhou 14 crew is set to depart for the space station sometime in June. China plans on having the station finished by the end of the year, which will include the launch of two additional modules.
