NASA hopes that commercial space stations will orbit Earth once the International Space Station eventually retires, NASA Administrator Bill Nelson said today at the 36th Space Symposium. Space.com reports: The space station, which was completed in 2011, could retire as soon as 2024. However, today, Nelson revealed that he expects the orbiting lab to last to 2030 and that NASA hopes it will be replaced by commercial labs in orbit. "We expect to expand the space station as a government project all the way to 2030. And we hope it will be followed by commercial stations," Nelson said during a "Heads of Agency" panel alongside other space leaders from around the world.

Now, while NASA hopes for commercial space stations to take over as the International Space Station nears the end of its tenure, China has already begun building its own space station. And, as NASA is prohibited from engaging in bilateral activities with China, this move by China is more competitive than collaborative. "Unfortunately, I believe we're in a space race with China," Nelson said during the panel. "I'm speaking on behalf of the United States, for China to be a partner. I'd like China to do with us as a military adversary, like Russia has done ... I would like to try to do that. But China is very secretive, and part of the civilian space program is that you've got to be transparent." Nelson pointed to Russia's longstanding history as a collaborator alongside NASA in space, despite ongoing political divides back on Earth.

Nasa is delaying a spacewalk at the International Space Station because of a medical issue involving one of its astronauts. From a report: Officials announced the postponement on Monday, less than 24 hours before Mark Vande Hei was supposed to float outside. Vande Hei was dealing with "a minor medical issue," officials said. It was not an emergency, they noted, but did not provide any further details. Vande Hei, 54, a retired army colonel, has been at the space station since April and is expected to remain there until next spring for a one-year mission. This is his second station stay.

Remember that small leak on the International Space Station discovered in 2018 that was traced to a Russian module and apparently made by a drill bit? (Implicating the technicans that built the module on earth, Ars Technica wrote "There is evidence that a technician saw the drilling mistake and covered the hole with glue, which prevented the problem from being detected...")

It's being revisited in the aftermath of a more recent incident involving Russia's Nauka science module to the International Space Station. (A software glitch after launch had required two course corrections for its rocket, and then while docking in space the module mistakenly fired its thrusters, causing the space station to briefly loss control, as well as communication with earth for 11 minutes.) Russia "is furious at what it says is unfair criticism of its space program," notes Futurism.com.

In response, Russia's state-owned news agency TASS has presented an anonymous interview with someone said to be a "high ranking" official at their space agency suggesting that the 2018 drill hole could've been caused by an emotionally unstable NASA flight engineer onboard the space station. The state-owned agency's story claims this flight engineer had discovered a blood clot in their jugular vein, and could've decided their return to earth for medical treatment might be expedited by sabotaging Russia's module. The problem with this story? Space.com reports: NASA officials knew the precise locations of the U.S. astronauts before the leak occurred and at the moment it began, thanks to space station surveillance. The video footage indicated that none of the U.S. astronauts on the station were near the Russian segment where the Soyuz vehicle was docked.
So Russia's state-owned news agency TASS now suggests that NASA could've tampered with that video to cover-up sabotage by NASA's astronauts — and points out that they weren't allowed to administer lie-detecting polygraph tests to those astronauts.

Asked to comment on the "unstable astronaut" theory, NASA's human spaceflight chief said they "did not find this accusation credible."

Ars Technica calls Russia's claims "extraordinarily defamatory."

Boeing's Starliner astronaut capsule won't be launching to the International Space Station until it's gone through "deeper-level troubleshooting" to fix an issue with stuck propulsion system valves, according to a press release from the company. That troubleshooting means removing the capsule from the Atlas V rocket it's been coupled to and bringing it back to Boeing's facility. The Verge reports: The spacecraft's initial launch attempt late last month was scrubbed hours before liftoff after engineers noticed a group of fuel valves in the Starliner's propulsion section weren't positioned as programmed. That valve issue, whose cause remains a mystery, is the latest engineering predicament to curse Starliner nearly two years after the capsule failed its first attempt to reach the space station in 2019. With a clear fix to the valve issue still elusive, having to take Starliner back to the hangar will push Boeing's plans to launch this month off the table, and a logjam of other scheduled flights could extend the delay by several months.

According to Boeing VP John Vollmer, the company will "continue to work the issue from the Starliner factory and have decided to stand down for this launch window to make way for other national priority missions." The new launch date will have to be jointly decided by NASA, Boeing, and the United Launch Alliance after the issue with the valves has been found and fixed. Boeing has said software isn't to blame for Starliner's new valve problem, and indicated in past statements that it's a more complex hardware issue.

destinyland shares a report from CNN: An unusual and potentially dangerous situation unfolded Thursday at the International Space Station, as the newly-docked Russian Nauka module inadvertently fired its thrusters causing a "tug of war" with the space station and briefly pushing it out of position, according to NASA flight controllers. Nauka -- a long-delayed laboratory module that Russian space agency Roscosmos' launched to the International Space Station last week -- inadvertently fired its thrusters after docking with the International Space Station Thursday morning.

NASA officials declared it a "spacecraft emergency" as the space station experienced a loss of attitude (the angle at which the ISS is supposed to remain oriented) control for nearly one hour, and ground controllers lost communications with the seven astronauts currently aboard the ISS for 11 minutes during the ordeal. A joint investigation between NASA and the Russian space agency Roscosmos is now ongoing. "The incident also delayed the launch of the Boeing Starliner uncrewed test flight to the station, which had been set to launch on Friday," adds CNN.

"NASA says the move allows the 'International Space Station team time to continue working checkouts of the newly arrived Roscosmos' Nauka module and to ensure the station will be ready for Starliner's arrival.'"

On Monday, astronauts said goodbye to a cornerstone of the International Space Station and captured stunning images of the compartment burning up in Earth's atmosphere. Space.com reports: A Russian Progress cargo vehicle towed the module, called Pirs, away from the space station and down through Earth's atmosphere to ensure the module burned up completely and reduce the odds of any large chunks making it to Earth's surface. Russia had launched its Pirs module in 2001; since then, the module, which served as a port to the space station, hosted more than 70 different capsules and supported Russian cosmonauts conducting extravehicular activities, or spacewalks. To make room for Russia's new science module, dubbed Nauka, which launched on July 21 and will arrive at the station on Thursday (July 29), Pirs had to go. Yesterday's fiery retirement ceremony marks the first time a major component of the International Space Station has been discarded. The attached Progress vehicle, which had arrived at the space station in February, controlled Pirs' re-entry to ensure that the module was destroyed as thoroughly as possible. European Space Agency astronaut Thomas Pesquet shared the photographs on Flickr.

Jupiter's unusual icy moon Europa may be one of the best spots in the solar system to check for signs of alien life. But first we have to get there. NASA's Europa Clipper spacecraft will get a boost in the right direction from a SpaceX Falcon Heavy, one of the most powerful rockets ever built. From a report: NASA announced Friday that it has selected SpaceX to provide the launch services for the Jupiter moon mission. The launch is scheduled for October 2024 from the Kennedy Space Center in Florida. The contract is worth about $178 million. Europa Clipper will try to determine if the moon could possibly host life. "Key mission objectives are to produce high-resolution images of Europa's surface, determine its composition, look for signs of recent or ongoing geological activity, measure the thickness of the moon's icy shell, search for subsurface lakes, and determine the depth and salinity of Europa's ocean," said NASA. SpaceX has been working with NASA on many fronts, including carrying astronauts to and from the International Space Station, delivering cargo to the ISS and developing a human landing system to return astronauts to the moon through the Artemis program.

First Slashdot reader Thelasko quotes the BBC's report Wednesday: A Russian rocket has departed the Baikonur Cosmodrome, Kazakhstan, to deliver a new science module to the International space station (ISS). The 13m-long, 20-tonne [44,000-pound] Nauka laboratory will go on the rear of the orbiting platform, connected to the other major Russian segments, Zvezda and Zarya. The new module carries with it a large robotic arm supplied by the European Space Agency (Esa).

Nauka is much delayed. It was originally supposed to launch in 2007. But it suffered repeated slips in schedule, in part because of budget difficulties but also because engineers encountered a raft of technical problems during development.

The module will result in a significant boost in habitable volume for the ISS, raising it by 70 cubic metres.
It's expected to dock this Thursday (July29), according to CBS News, after which "It will take up to 11 Russian spacewalks over about seven months to electrically connect and outfit the new lab module, providing a new airlock, research space, living quarters, a European Space Agency robot arm and other systems."

But Friday Gizmodo reported the attempt to deliver the module to the Space Station "is still having problems." The first glitch in Nauka's journey happened yesterday, when the spacecraft didn't complete its first orbit-raising burn. This meant that the uncrewed Nauka wasn't on track to actually intercept the ISS, which it's scheduled to dock with on Thursday, July 29. The problem was attributed to a software issue in a computer aboard Nauka, which prevented the spacecraft's main engines from firing. Nauka's team was able to manage a remote course correction, but a second bout of course corrections were deemed necessary, and scheduled for Friday...

Nauka's also been having issues with one antenna and its docking target, and its uncertain how those issues will affect docking attempts, SpaceNews reported. "Apparently there is still an issue with the Kurs rendezvous system, and that is pretty critical for docking," said Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, adding that the spacecraft's TORU system — which allows the astronauts aboard the ISS assist with the docking — is working normally. For now, the Pirs docking compartment is currently sitting in Nauka's assigned dock on the ISS. Pirs' scheduled undocking to make way for the new module was postponed from Friday to Sunday, .

India's CNN-News18 reports: [P]revious research has found that how cells pick a particular repair strategy can be influenced by the microgravity conditions in space. Scientists are concerned that DNA repairs influenced by microgravity conditions may not be adequate, and can lead to harmful consequences. To study the DNA repair process in space, scientists have developed a new technique that uses CRISPR/Cas9 — a gene-editing technology — to recreate precise damages so that cells can be observed repairing them. The team of researchers led by Sarah Stahl-Rommel has successfully demonstrated the technique and its viability aboard the International Space Station.
"CRISPR gene editing is no longer confined to Earth," reports Engadget: The new approach clears the way for other research around DNA repair in space. With enough work, the scientists hope they can replicate the genetic damage from ionizing radiation, not to mention other effects from long-term spaceflight. That, in turn, could help NASA and other agencies develop technology that shields astronauts and makes deep space exploration practical. There's a chance CRISPR might play an important role in getting humans to Mars and beyond.

For the next three months, three Chinese astronauts will live on a cylinder-shaped module measuring 16.6 metres by 4.2 metres (54 feet by 13.7 feet) while carrying out further construction work for China's orbiting space station.

It's the first time in five years China has sent humans into space, reports NBC News. : Shenzhou-12, or "Divine Vessel," is one of 11 planned missions to complete construction of China's 70-ton Tiangong or Harmony of the Heavens space station that is set to be up and running by next year... China has long been frozen out of the International Space Station, or ISS, a project launched 20 years ago that has served as the ultimate expression of post-Cold War reconciliation between Russia and the United States. American concerns over the Chinese space program's secrecy and connections to its military were largely responsible for that. But the aging ISS that hosted astronauts from the U.S., Russia and a number of other countries is set to be decommissioned after 2024. As broader U.S.-Russia relations deteriorate, Moscow has hinted that it may withdraw from ISS cooperation in 2025, meaning China could be the only country with a functioning space station.

Roscosmos, the Russian space agency, also signed an agreement in March with the Chinese National Space Administration to build a base on or around the Moon, which they will call the International Scientific Lunar Station.

"All the firsts that the U.S. and the USSR did in the Cold War, China is just ticking them off," said Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics. "Now they're at the point where they're starting to think, 'OK, we're not just copying the West anymore, we're going to start doing our own thing'. And that's going to be very interesting to watch."

In the longest biological experiment on the International Space Station yet, freeze-dried mouse sperm remained viable after nearly six years in space. Exposure to space radiation didn't seem to harm the sperm's DNA or the cells' ability to produce healthy "space pups," researchers report in Science Advances. Science News reports: That may be good news for future spacefarers. Scientists have worried that chronic exposure to space radiation might not only put astronauts at risk for cancer and other diseases, but also create mutations in their DNA that could be passed down to future generations. The new results hint that deep-space travelers could safely bear children. Studying how space radiation affects reproduction is tricky. Instruments on Earth can't perfectly mimic space radiation, and the ISS lacks freezers for long-term cell storage. So biologist Teruhiko Wakayama of the University of Yamanashi in Kofu, Japan and colleagues freeze-dried sperm, allowing it to be stored at room temperature. The team then sent sperm from 12 mice to the space station, while keeping other sperm from the same mice on the ground.

After returning the sperm cells to Earth, rehydrating them and injecting them into fresh mouse eggs, the team transferred those embryos to female mice. About 240 healthy space pups were born from sperm kept on the ISS for nearly three years; about 170 others were born from sperm kept on the space station for nearly six years. Genetic analyses revealed no differences between these space pups and mice born from sperm stored on the ground. Space pups that mated as adults had healthy children and grandchildren.

A user shares a report from ScienceAlert: The inevitable has occurred. A piece of space debris too small to be tracked has hit and damaged part of the International Space Station -- namely, the Canadarm2 robotic arm. The instrument is still operational, but the object punctured the thermal blanket and damaged the boom beneath. It's a sobering reminder that the low-Earth orbit's space junk problem is a ticking time bomb. Canadarm2 -- formally known as the Space Station Remote Manipulator System (SSRMS), designed by the Canadian Space Agency -- has been a fixture on the space station for 20 years. It's a multi-jointed titanium robotic arm that can assist with maneuvering objects outside the ISS, including cargo shuttles, and performing station maintenance.

It's unclear exactly when the impact occurred. The damage was first noticed on 12 May, during a routine inspection. NASA and the CSA worked together to take detailed images of and assess the damage. "Despite the impact, results of the ongoing analysis indicate that the arm's performance remains unaffected," the CSA wrote in a blog post. "The damage is limited to a small section of the arm boom and thermal blanket. Canadarm2 is continuing to conduct its planned operations." Robotics operations on the ISS using the Canadarm2 will continue as planned for the near future, the CSA said. But both space agencies will continue to gather data in order to perform an analysis of the event, both to understand how it occurred, and to assess future risk.

Who wants to be an astronaut? If the answer is you, there's a reality TV show, appropriately titled "Who Wants to Be an Astronaut?", that you ought to apply for. From a report: The Discovery Channel is seeking to cast about 10 would-be astronauts to compete during the series' eight-episode run next year for a seat on a real-life trip to the International Space Station, followed by live coverage of the launch of the winner on a SpaceX rocket. "We'd like a diverse group of people that each have their own story, why they want to go to space, why they're worthy of going to space, what their back story is," said Jay Peterson, president of Boat Rocker Studios, Unscripted, one of the companies producing the show for Discovery. That person will not be the only amateur astronaut destined for the space station next year. So many tourism and entertainment efforts are preparing trips there that it could begin to look more like a soundstage for television shows and a hotel for the wealthy than an orbiting research laboratory.

Many who work in the business of space believe that is a good thing, even if trips to orbit will remain out of reach of all but the wealthiest passengers in the near term. "This is a real inflection point, I think, with human spaceflight," Phil McAlister, NASA's director of commercial spaceflight development, said during a news conference this month announcing that the agency had signed an agreement with Axiom Space, a Houston-based company, to fly the first mission of private astronauts to the space station. "I'm very bullish on the tourism market and the tourism activity," Mr. McAlister said. "I think more people that are going to fly, they're going to want to do more things in space." Although the International Space Station may stay up in orbit at least until 2028, in the future it will not be only space station. Russian space authorities last month declared their intention to leave the I.S.S. in the coming years and build a station of their own. A Chinese orbital outpost is expected to come online in the next year or two.

NASA and Houston-based Axiom Space have signed a "mission order" setting the stage for four civilians to visit the International Space Station early next year, the first fully commercial flight to the orbiting lab complex, agency managers said Monday. CBS News reports: Axiom's "AX-1" mission and an upcoming charity-driven flight to low-Earth orbit, both aboard SpaceX Crew Dragon capsules, represent "a renaissance in U.S. human spaceflight," said Phil McAlister, NASA's director of commercial spaceflight development. "I think that's the perfect word for what we're experiencing," he said of the growing commercial space market, which includes the anticipated certification of Boeing's CST-100 Starliner and upcoming sub-orbital flights by Blue Origin and Virgin Galactic. "This is a real inflection point, I think, with human spaceflight."

Axiom Space, led by Mike Suffredini, NASA's former space station program manager, announced last year that it plans to launch a four-man crew to the space station aboard a SpaceX Crew Dragon capsule. The launch is currently targeted for a January timeframe. Axiom Vice President Mike Lopez-Alegria, a former NASA astronaut and space station commander, will serve as commander of the AX-1 mission, which is expected to last about 10 days. Joining him will be Larry Connor, an American entrepreneur, Canadian investor and philanthropist Mark Pathy and Israeli investor Eytan Stibbe, a former fighter pilot.

Lopez-Alegria on Monday told reporters that the crew will participate in centrifuge training and flights to simulate weightlessness starting next week, followed by a camping trip to Alaska in July for "bonding and leadership training." Lopez-Alegria and Connor, the mission pilot, will begin SpaceX flight training shortly thereafter before the entire crew begins space station familiarization at the Johnson Space Center in October. [...] Axiom is not paying list price for the AX-1 mission, in part because planning began before the new price guidelines were determined and because the company will be providing services to NASA that the agency would otherwise have to pay for. The mission order announced Monday covers just $1.69 million. Additional agreements remain to be negotiated.

Four astronauts in a SpaceX Dragon capsule successfully splashed down into the Gulf of Mexico this morning at 2:57 a.m. ET — returning from the International Space Station in the first U.S. crew splashdown in darkness since the Apollo 8 moonshot in 1968.

Phys.org reports: It was an express trip home, lasting just 6 1/2 hours... "We welcome you back to planet Earth and thanks for flying SpaceX," SpaceX's Mission Control radioed moments after splashdown. "For those of you enrolled in our frequent flyer program, you've earned 68 million miles on this voyage...."

The 167-day mission was the longest for a crew capsule launching from the U.S. The previous record of 84 days was set by NASA's final Skylab station astronauts in 1974. Saturday night's undocking left seven people at the space station, four of whom arrived a week ago via SpaceX...

Once finished with their medical checks on the ship, the astronauts planned to hop on a helicopter for the short flight to shore, then catch a plane straight to Houston for a reunion with their families. "It's not very often you get to wake up on the space station and go to sleep in Houston," chief flight director Holly Ridings told reporters.

The astronauts' capsule, Resilience, will head back to Cape Canaveral for refurbishment for SpaceX's first private crew mission in September... A tech billionaire has purchased the entire three-day flight, which will orbit 75 miles (120 kilometers) above the space station. He'll fly with a pair of contest winners and a physician assistant from St. Jude Children's Research Hospital, his designated charity for the mission.

SpaceX's next astronaut launch for NASA will follow in October.

Hmmmmmm shares a report from Phys.Org: China plans to launch the core module for its first permanent space station this week in the latest big step forward for the country's space exploration program. The Tianhe, or 'Heavenly Harmony' module is set to be hurtled into space aboard a Long March 5B rocket from the Wenchang Launch Center on the southern island of Hainan. The launch could come as early as Thursday night if all goes as planned. It would be the first of 11 missions to build and supply the space station for a three-person crew. Another 10 launches will send up two more modules; four cargo supply shipments and four missions with crews. At least 12 astronauts are training to fly to and live in the station, including veterans of previous flights, newcomers and women.

When completed by late 2022, Tianhe is expected to weigh about 66 tons, a fraction the size of the International Space Station, which launched its first module in 1998 and will weigh about 450 tons when completed. Tianhe will have a docking port and will also be able to connect with a powerful Chinese space satellite. Theoretically, it could be expanded with more modules.

NASA has tweeted a video showing the arrival of four astronauts from three countries on the International Space Station early Satuday morning.

CNN describes the significance to their arrival — and what the astronauts will do during their six-month stay in space: This mission, dubbed Crew-2, marks the third-ever crewed flight for Elon Musk's company and the first to make use of a previously flown, privately-owned rocket booster and spacecraft... On Saturday morning, the capsule slowly aligned itself and moved in to dock directly with one of the space station's ports.

The crew consists of NASA astronauts Shane Kimbrough and Megan McArthur, Thomas Pesquet of the European Space Agency, and Akihiko Hoshide with Japan's JAXA space agency.

A prime focus of the astronauts' mission will be research with "tissue chips," or "small models of human organs containing multiple cell types that behave much the same as they do in the body" and that NASA hopes will advance the development of drugs and vaccines, according to the space agency. That work will build on years of studying biological and other scientific phenomena aboard the ISS, where the microgravity environment can give scientists a better fundamental understanding of how something works.

Kimbrough, McArthur, Pesquet, and Hoshide joined seven astronauts already on board the station, four of whom arrived on a different SpaceX Crew Dragon capsule in November. That brings the space station's current total of personnel to 11 — one of the largest crews the ISS has ever hosted. But that number will quickly drop back down to seven when four of the astronauts who'd been on board hitch a ride home from the station on April 28.

SpaceX has another successful human space launch to its credit, after a good takeoff and orbital delivery of its Crew Dragon spacecraft on Friday morning. From a report: The Dragon took off aboard a Falcon 9 rocket from Cape Canaveral in Florida at 5:49 AM EDT (2:49 AM EDT). On board were four astronauts, including NASA's Megan McArthur and Shane Kimbrough, as well as JAXA's Akihiko Hoshide and the ESA's Thomas Pesquet. This was Spacex's second official astronaut delivery mission for NASA, after its Crew-1 operation last year.

SpaceX has characterized the use of re-flown elements as arguably even safer than using new ones, with CEO Elon Musk noting that you wouldn't want to be on the "first flight of an airplane when it comes out of the factory" during a conversation with Xprize's Peter Diamandis on Thursday evening. Now that the Crew Dragon is in its target transfer orbit, it'll be making its way to rendezvous with the Space Station, which will take just under 24 hours. It'll be docking with the station early tomorrow morning, attaching to a docking port that was just cleared earlier this month when SpaceX's other Crew Dragon relocated to another port on the ISS earlier this month.

As the 20-year-old International Space Station (ISS) starts showing its age, Russian Deputy Prime Minister Yury Borisov suggested Russia would back away from the ISS as early as 2025 to pursue a national space station. Science Magazine reports: Although he and other officials have since backpedaled from such a concrete date for withdrawal, Russian skepticism over the future of the ISS could complicate U.S. efforts to keep it operating until the end of the decade. "ISS partners would have a really hard time keeping the station functional without Russia," says Vitaly Egorov, an industry observer, writer, and former spokesperson for Dauria Aerospace, a Russian company.

On 18 April, Russia 1, a state TV channel, reported that Borisov told a meeting chaired by President Vladimir Putin, "We need to honestly inform our partners about leaving the ISS in 2025." In a statement to newswires released later that day, Borisov's office clarified his remarks and backtracked from the date. "A technical inspection is needed, and then we can make a decision and inform our partners," the statement said. But it reiterated that the ISS has run well past its original life span, and its condition "leaves much to be desired."

Seemingly downplaying Borisov's remarks this week, Dmitry Rogozin, who leads Roscosmos, the Russian space agency, said on Monday that Russia would not pull out of the ISS until the proposed new station becomes functional. "Pauses are deadly for human spaceflight," he wrote in a Facebook post. Rogozin later added that the new station, which does not have a name yet, could be based on one of the modules initially planned for the ISS.

If your heart stops en route to Mars, rest assured that researchers have considered how to carry out CPR in space. (One option is to plant your feet on the ceiling and extend your arms downwards to compress the patient's chest.) From a report: Astronauts, because of their age range and high physical fitness, are unlikely to suffer a stroke or have their appendix suddenly explode. That's good because, if it does happen, they're in the realm of what Jonathan Scott -- head of the medical projects and technology team at the European Space Agency -- describes as 'treatment futility.' In other words: there's nothing anyone can do about it. On the ISS, when medical incidents arise, astronauts can draw on the combined expertise of a host of medical experts at Nasa. "The patient is on the space station, the doctor is on the ground, and if there's a problem the patient consults the doctor," says Scott. By the time astronauts reach Mars, there'll be a 40-minute time lag in communications, if it's possible to make contact at all. "We have to begin preparing for not only being able to diagnose things in spaceflight but also to treat them as well," Scott says.

Artificial intelligence is likely to be a part of the solution. If you're imagining the holographic doctor from Star Trek, downgrade your expectations, at least for the next few decades. Kris Lehnhardt, the element scientist for exploration medical capability at Nasa, says: "We are many, many, many years away from: please state the nature of the medical emergency." Emmanuel Urquieta is deputy chief scientist at the Translational Institute for Space Health (TRISH), a Nasa-funded program which conducts research into healthcare for deep space missions. While full AI may be a way off, Urquieta believes some form of artificial intelligence will still play a crucial role. "It's going to be essential for a mission to Mars," he says. While the crew for a mission to Mars will likely include a medical doctor, he explains: "No single physician can know everything." And, of course: "What happens if that astronaut gets sick?" Research projects funded by TRISH include Butterfly iQ, a handheld ultrasound device for use by non-medical personnel to make diagnoses that would otherwise require bulky equipment and a trained operator. VisualDx is an AI diagnostics tool originally developed to analyse images and identify skin conditions. The technology is now being adapted to help astronauts diagnose a wide range of conditions most commonly encountered in space, without an internet connection.
