The BBC reports: China's Zhurong rover has sent back a batch of new images from Mars — including a "selfie". The robot, which landed in May, positioned a wireless camera on the ground and then rolled back a short distance to take the snap. To Zhurong's right is the rocket-powered platform that brought the six-wheeled vehicle to a soft touchdown. Both display prominent Chinese flags...

It weighs some 240kg. A tall mast carries cameras to take pictures and aid navigation; five additional instruments will investigate the mineralogy of local rocks and the general nature of the environment, including the weather. Like the current American rovers (Curiosity and Perseverance), Zhurong has a laser tool to zap rocks to assess their chemistry. It also has a radar to look for sub-surface water-ice - a capability it shares with Perseverance.
Slashdot reader InfiniteZero writes that the mission's "full resolution images including a 360 panoramic view of the landing site, can be found at the official CNSA website."

sciencehabit shares a report from Science Magazine: Venus can no longer wait. NASA will send two new robotic missions to Earth's hothouse twin, the agency's new administrator, Bill Nelson, announced this afternoon at his "State of NASA" speech here at the agency's headquarters. The missions, together costing up to $1 billion, mark NASA's first visit to the planet since the early 1990s, whereas nearby Mars has seen a host of robotic visitors. They're expected to launch by the decade's end.

The scientific case for exploring Venus has long been strong. No planet has more to say about how Earth came to be. Mars is tiny and frozen, its heat and atmosphere largely lost to space long ago. Venus could host active volcanoes, and it may have once featured oceans and continents, which are critical to the evolution of life. Plate tectonics roughly like Earth's might have held sway there, or might be starting today, hidden under the clouds. Venus also proves by example that orbiting within a star's "habitable zone" doesn't guarantee a planet is suitable for life. Understanding how Venus's atmosphere went bad and turned into a runaway greenhouse, boiling away any oceans and baking the surface, could help astronomers studying other solar systems distinguish truly Earth-like exoplanets from our evil twins.

A navigation timing error sent Nasa's Mars helicopter on a lurching ride, its first major problem since it took to the Martian skies last month. The Associated Press reports: The experimental helicopter, named Ingenuity, managed to land safely after the problem occurred, officials at the Jet Propulsion Laboratory said on Thursday. The trouble cropped up about a minute into the helicopter's sixth test flight on Saturday at an altitude of 10 meters (33ft). One of the numerous pictures taken by an onboard navigation camera did not register in the system, confusing the craft about its location. Ingenuity began tilting back and forth by as much as 20 degrees and suffered power consumption spikes, according to Havard Grip, the helicopter's chief pilot.

A built-in system to provide extra margin for stability "came to the rescue," he wrote in an online status update. The helicopter landed within five meters (16ft) of its intended touchdown site. Grip wrote: "Ingenuity muscled through the situation, and while the flight uncovered a timing vulnerability that will now have to be addressed, it also confirmed the robustness of the system in multiple ways. While we did not intentionally plan such a stressful flight, Nasa now has flight data probing the outer reaches of the helicopter's performance envelope."

The space-news web site NASASpaceFlight writes: While organic compounds have been confirmed on the Martian surface and near-surface areas since 2018, new Earth-based experiments point to a potentially tantalizing series of signatures from Curiosity's Sample Analysis at Mars (SAM) instrument that could indicate the presence of organic salts at the rover's Gale Crater location. What's more, the new research from a team led by J. M. T. Lewis, an organic geochemist at NASA's Goddard Space Flight Center, points to further potential evidence that organic salts might be prevalent across the Martian terrain. The hard part is conclusively detecting them.

For decades, scientists theorized that organic compounds were almost certainly to have been preserved to some detectable degree in the Martian surface environment. In 2018, Curiosity's instruments allowed Eigenbrode et al. to conclusively prove that they were in fact there. In turn, if organic compounds were present at one time, their by-products — organic salts — would still be around as well, even given the harsh radiation environment of Mars compared to Earth.

While organic compounds and organic salts can form from the presence of microbial life, they can also form from geologic processes. Though not confirmed, organic salts would be further evidence that organic matter once existed on Mars' surface, and, if they are still present, could support hypothetical microbial life on Mars today, as some life on Earth uses organic salt as food/energy.

China has released the first photographs taken by its Zhurong rover, which touched down on Mars late on May 14 as part of the country's Tianwen-1 mission. Space.com reports: The China National Space Administration (CNSA), which runs the mission, has released two Mars photographs taken by the rover: one in color and one in black and white. Both images show parts of the rover and its lander against a backdrop of Utopia Planitia, the expansive northern plain that Zhurong will explore during its mission.

The color image shows a view looking to the rear of Zhurong from a navigation camera above the rover's main deck. Solar arrays are visible, as are some surface rocks and features. The black and white image is from an obstacle avoidance camera at the front of the rover. It was captured with a wide-angle lens that also revealed a view of the Mars horizon in the distance, as well as two subsurface radar instruments on the rover itself. In addition to the photos from the surface, CNSA also released two short videos of the orbiter and Zhurong rover's landing capsule separating during Friday's maneuver. Both videos come from cameras on the orbiter and show the capsule pulling away.

China just successfully landed its first rover on Mars, becoming only the second nation to do so. Space.com reports: The Tianwen-1 mission, China's first interplanetary endeavor, reached the surface of the Red Planet Friday (May 14) at approximately 7:11 p.m. EDT (2311 GMT), though Chinese space officials have not yet confirmed the exact time and location of touchdown. Tianwen-1 (which translates to "Heavenly Questions") arrived in Mars' orbit in February after launching to the Red Planet on a Long March 5 rocket in July 2020. After circling the Red Planet for more than three months, the Tianwen-1 lander, with the rover attached, separated from the orbiter to begin its plunge toward the planet's surface. Once the lander and rover entered Mars' atmosphere, the spacecraft endured a similar procedure to the "seven minutes of terror" that NASA's Mars rovers have experienced when attempting soft landings on Mars.

A heat shield protected the spacecraft during the fiery descent, after which the mission safely parachuted down to the Utopia Planitia region, a plain inside of an enormous impact basin in the planet's northern hemisphere. Much like during NASA's Perseverance rover landing, Tianwen-1's landing platform fired some small, downward-facing rocket engines to slow down during the last few seconds of its descent. China's Mars rover, called Zhurong after an ancient fire god in Chinese mythology, will part ways with the lander by driving down a foldable ramp. Once it has deployed, the rover is expected to spend at least 90 Mars days (or about 93 Earth days; a day on Mars lasts about 40 minutes longer than a day on Earth) roving around on Mars to study the planet's composition and look for signs of water ice. Utopia Planitia is believed to contain vast amounts of water ice beneath the surface. It's also where NASA's Viking 2 mission touched down in 1976.

China is all set to attempt its first landing on another planet. After months in orbit around Mars, the Tianwen-1 spacecraft will deposit a rover called Zhurong on the surface of Mars. If successful, China will become the second country in history to explore the Martian surface with a rover. From a report: Tianwen-1 arrived at Mars on February 10, marking the arrival of China's first independent interplanetary mission. Since then, Tianwen-1 has been making close approaches to Mars every 49 hours as it flies in an elliptical orbit around the planet, each time taking high-resolution images of the landing site in Utopia Planitia, a vast plain that may once have been covered by an ancient Martian ocean. Chinese officials have said the landing attempt would take place in mid-to-late May, and a report on Twitter quoted Ye Peijian of the China Association for Science and Technology saying the landing will take place on May 14 at 7:11 p.m. ET. This aligns with estimates from amateur radio astronomers tracking the spacecraft.

Mission scientists have been analyzing the topography and geology of Utopia Planitia to guide the spacecraft's landing attempt, and if they decide not to attempt a landing on May 14, they will have additional opportunities on May 16 and May 18. Named for an ancient Chinese fire god, the 529-pound Zhurong rover is similar in size to NASA's Spirit and Opportunity rovers, which landed on the red planet in 2004 and sent back exciting images and data about the planet's surface conditions. China's rover could make additional important discoveries concerning water and past habitability on the planet, paving the way for future human missions to Mars.

NBC News reports on what exactly happened during Elon Musk's appearance on Saturday Night Live — starting with a surprisingly personal monologue: "I don't always have a lot of intonation or variation in how I speak," Musk said, "which I'm told makes for great comedy." He admitted he's socially awkward and said he was the first person with Asperger syndrome to host the show — "or at least the first to admit it."

"I know I sometimes say or post strange things but that's just how my brain works," Musk, 49, said. "I reinvented electric cars and I'm sending people to Mars on a rocket ship. Did you think I was also going to be a chill, normal dude?"
ET Canada notes that Twitter users later pointed out that former SNL castmember (and later episode host) Dan Aykroyd has also said he was diagnosed with Asperger syndrome. But NBC notes that Saturday's show was focused on the interests and eccentricities of Elon Musk. His mother, Maye Musk, appeared as part of the show's pre-celebration of Mother's Day. "I'm excited for my Mother's Day gift," she said, before mentioning a form of cryptocurrency hyped by her son. "I just hope it's not Dogecoin."

"It is," said Musk, a big investor in the cryptocurrency...
And later in a skit with Michael Che, Musk had also played a fictional cryptocurrency expert who's asked repeatedly to explain Dogecoin. "It actually started as a joke based on an internet meme but now it's taken over in a very real way," Musk said. "It's the future of currency." Asked again by Che, he said, "I keep telling you, it's a cryptocurrency you can trade for conventional money."

"Oh," Che said. "So it's a hustle."

"Yeah," Musk said, "it's a hustle...."

Dogecoin tracker Darren Rovell tweeted that the cryptocurrency had, at one point, lost $30 billion in value during the show.
In fact, by early Sunday Dogecoin was down 40%, trading as low as 44 cents, reports CNN: It's unclear what was driving the dogecoin selloff. Perhaps investors wanted Musk to say something more supportive of the cryptocurrency. But more likely, there was some "buy the rumor / sell the news" strategy, trying to capitalize on investors' predictions coming true by selling high. Dogecoin traded so actively that Robinhood announced early Sunday morning it was having issues processing crypto trades and was working to resolve the problem.

Several science web sites are strongly disputing a China-based journal's claim that time-lapse photos of Mars show growing mushrooms.

TNW Neural headlined their story "Mushrooms on Mars is a hoax — stop believing hack 'scientists'" If you believe those images demonstrate fungus growing on Mars, I'm about to blow your frickin' mind. Check out this pic. You see that? To heck with fungus, that's an entire highway growing out of the sand in front of a moving bus. You can clearly see that the Earth's sandy crust is being broken apart as the expanding highway organism grows beneath it.

Or, if you're the "Occam's Razor" type: the wind is just blowing sand around. I've never been to Mars, but I'm led to believe there are rocks, dust, and wind. Do we really need to go any further in debunking this nonsense?
They also link to Retraction Watch's page about the story's lead author, Rhawn Gabriel Joseph. IFL Science picks up the story: Nicknamed the Space Tiger King — due to the photographs posted on his frankly ridiculous personal website — Joseph has spent decades erroneously claiming that life has already been discovered on other planets. Back in the 1970s, he began alleging that NASA's Viking lander had found biological matter, despite the agency stating the exact opposite of this.

After setting up his own journal in an attempt to air his unscientific assertions, he later filed a lawsuit against NASA in order to force them to investigate a structure which he claimed resembled a "putative biological organism", but which later turned out to be a rock.
CNET adds: "Claiming that mushrooms are sprouting all over Mars is an extraordinary claim that requires better evidence than an analysis of photographic morphology by a known crank who has claimed, on the basis of the same kind of analysis, that he has seen fields of skulls on Mars," says Paul Myers, a developmental biologist at the University of Minnesota, Morris, who has followed Joseph's work in the past...

After being alerted to the new paper on Wednesday, I sent emails to the associate editors-in-chief of Advances in Microbiology, asking for clarification around the peer review process. They have not responded to requests for comment. I also emailed members of the editorial board listed on SCIRP's website, including Jian Li, a microbiologist at Monash University in Australia. He says he has not been on the journal's editorial board "for at least five to six years" and has not handled any of the papers in the journal.
The "mushrooms" theory was also dismissed by several actual scientists, reports Futurism: "The conditions on Mars are so extreme that you're not going to see fungi or any kind of life growing at that sort of speed under conditions like coldness and low air pressure," Jonathan Clarke, president of Mars Society Australia, told the South China Morning Post. "Life can barely survive, let alone thrive."

Clarke also took issue with the paper claiming that mushrooms were actually growing on Mars. "It's just like if you go to a beach and there are shells," he told the newspaper. "If the wind blows, the sand moves and exposes more shells. But we won't say the shells are growing there, it's just that they become visible..."

"We have more than photos, records, instruments that tell us what these materials are made of," David Flannery, lecturer at the Queensland University of Technology who is a member of NASA's Mars 2020 mission science team, told SCMP. "And we have models for the features we see around us.... Robots are sending back huge amounts of data," he added. "We have plenty of information but it's just that no one is interpreting the features that we see as something like fungi. There's zero evidence for that."

"This paper, which is really not credible, will be ignored by the scientific community," Flannery said.

"A ghostly hum has been echoing across the plains of Mars' Jezero Crater," reports Business Insider.

Slashdot reader quonset writes: NASA has released a short video of Ingenuity's fourth flight on Mars. However, a bountiful side effect is they were able to hear the hum of its rotors.

Perseverance's microphone was turned on during the flight, and despite Ingenuity being over 260 feet away, it was able to capture both sight and sound of the historic event.

While the majority of sound is Martian wind rustling against the microphone, NASA enhanced the sound to make the rotor sounds more audible. They are most apparent when Ingenuity returns to its takeoff spot and the rotor hum dies down when the blades come to a halt.
"We had carried out tests and simulations that told us the microphone would barely pick up the sounds of the helicopter, as the Mars atmosphere damps the sound propagation strongly," said NASA's science lead for the Perseverance rover's microphone.

"We have been lucky to register the helicopter at such a distance. This recording will be a gold mine for our understanding of the Martian atmosphere."

NASA's Ingenuity helicopter completed its fourth and most ambitious test flight across Mars on Friday. CNET reports: NASA JPL tweeted "Success," saying Ingenuity went father and faster than ever before. NASA also shared a nifty image from one of the Perseverance rover's cameras showing the helicopter in flight in the distance. Ingenuity had originally been scheduled for a fourth flight on Thursday, but a known glitch prevented the rotorcraft from switching into flight mode. The chopper remained safe and healthy and ready for the redo.

The plan for the latest test was to fly the helicopter to an altitude of 16 feet (5 meters), collect images of the landscape below, hover and then head back to its takeoff spot. The flight path was set to take it 436 feet (133 meters) downrange and last 117 seconds. It takes time to send the data back from Mars, but NASA is expecting to receive a bounty of photos snapped by the helicopter during the flight. This will help prove the rotorcraft's potential for use as a scout that can assist surface vehicles like rovers as they explore from the ground. NASA said the plucky chopper already "has met or surpassed all of its technical objectives." That gave the helicopter team license to try the more daring fourth flight to push its capabilities in the thin atmosphere of Mars.

Hmmmmmm writes: China plans to launch its next robot lunar lander in 2024, and it will carry equipment manufactured by scientists from France, Sweden, Italy, and Russia, Hu Hao, the program's chief designer, told the Xinhua News Agency on Saturday. The country aims to position the lander, named Chang'e 6, near the lunar south pole where it will collect samples, per the official Xinhua News Agency.

The Chang'e 6 lander is part of China's ongoing mission to successfully return moon samples back home "for comprehensive analysis and research," Hu said at a conference, Associated Press reported.

For the 2024 mission, The China National Space Administration has invited scientists from around the world to take part in the program, offering to transport solicited payloads into space. So far, four payloads designed by the international scientists have been preliminarily chosen, the Xinhua News Agency reported.

"NASA's Ingenuity Mars Helicopter continues to set records, flying faster and farther on Sunday, April 25, 2021 than in any tests it went through on Earth," reports NASA: The helicopter took off at 1:31 a.m. EDT (4:31 a.m. PDT), or 12:33 p.m. local Mars time, rising 16 feet (5 meters) — the same altitude as its second flight. Then it zipped downrange 164 feet (50 meters), almost half the length of a football field, reaching a top speed of 6.6 feet per second (2 meters per second). [Roughly 4.5 miles an hour.]

After data came back from Mars starting at 10:16 a.m. EDT (7:16 a.m. PDT), Ingenuity's team at NASA's Jet Propulsion Laboratory in Southern California was ecstatic to see the helicopter soaring out of view. They're already digging through a trove of information gathered during this third flight that will inform not just additional Ingenuity flights but possible Mars rotorcraft in the future. "Today's flight was what we planned for, and yet it was nothing short of amazing," said Dave Lavery, the project's program executive for Ingenuity Mars Helicopter at NASA Headquarters in Washington. "With this flight, we are demonstrating critical capabilities that will enable the addition of an aerial dimension to future Mars missions."
NASA's chief pilot for the Mars helicopter calls this flight a big step "in which Ingenuity will begin to experience freedom in the sky," according to CNN.

From the sky Ingenuity snapped a photo of its own shadow on Mars, and earlier sent back the very first aerial color image — taken 17 feet (5.2-metre) above the surface of Mars by Ingenuity's high-resolution color camera with a 4208-by-3120-pixel sensor.

NASA successfully carried out a second flight on Mars on Thursday of its mini helicopter Ingenuity, a 52-second sortie that saw it climb to a height of 16 feet. Phys.Org reports: "So far, the engineering telemetry we have received and analyzed tell us that the flight met expectations," said Bob Balaram, Ingenuity's chief engineer at NASA's Jet Propulsion Laboratory in southern California. "We have two flights of Mars under our belts, which means that there is still a lot to learn during this month of Ingenuity," Balaram said in a statement. The US space agency conducted the first flight of the four pound (1.8 kilogram) rotorcraft on Monday, the first powered flight ever on another planet. That time Ingenuity rose to a height of 10 feet and then touched down after 39.1 seconds.

For the second flight, which lasted 51.9 seconds, Ingenuity climbed to 16 feet, hovered briefly, tilted and then accelerated sideways for seven feet. "The helicopter came to a stop, hovered in place, and made turns to point its camera in different directions," said Havard Grip, Ingenuity's chief pilot. "Then it headed back to the center of the airfield to land. "It sounds simple, but there are many unknowns regarding how to fly a helicopter on Mars."

William Robinson shares a report: The growing list of "firsts" for Perseverance, NASA's newest six-wheeled robot on the Martian surface, includes converting some of the Red Planet's thin, carbon dioxide-rich atmosphere into oxygen. A toaster-size, experimental instrument aboard Perseverance called the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) accomplished the task. The test took place April 20, the 60th Martian day, or sol, since the mission landed Feb. 18. While the technology demonstration is just getting started, it could pave the way for science fiction to become science fact -- isolating and storing oxygen on Mars to help power rockets that could lift astronauts off the planet's surface. Such devices also might one day provide breathable air for astronauts themselves. MOXIE is an exploration technology investigation -- as is the Mars Environmental Dynamics Analyzer (MEDA) weather station -- and is sponsored by NASA's Space Technology Mission Directorate (STMD) and Human Exploration and Operations Mission Directorate. "This is a critical first step at converting carbon dioxide to oxygen on Mars," said Jim Reuter, associate administrator for STMD. "MOXIE has more work to do, but the results from this technology demonstration are full of promise as we move toward our goal of one day seeing humans on Mars. Oxygen isn't just the stuff we breathe. Rocket propellant depends on oxygen, and future explorers will depend on producing propellant on Mars to make the trip home." For rockets or astronauts, oxygen is key, said MOXIE's principal investigator, Michael Hecht of the Massachusetts Institute of Technology's Haystack Observatory.

An anonymous reader quotes a report from ZDNet: A small miracle happened at 3:31am ET on Monday morning. Ingenuity, a tiny NASA helicopter, became the first powered aircraft to fly on another planet, Mars. This engineering feat was done with Linux, open-source software, and a NASA-built program based on the Jet Propulsion Laboratory's (JPL) open-source F (pronounced F prime) framework. GitHub CEO Nat Friedman and his team and the JPL Ingenuity crew took a long hard look into the helicopter's code and found that "nearly 12,000 developers on GitHub contributed to Ingenuity's software via open source. And yet, much like the first image of a black hole, most of these developers are not even aware that they helped make the first Martian helicopter flight possible."

They'll know now. Friedman wrote: "Today, we want to make the invisible visible. So, we have worked with JPL to place a new Mars 2020 Helicopter Mission badge on the GitHub profile of every developer who contributed to the specific versions of any open-source projects and libraries used by Ingenuity." The developer list was created by JPL providing GitHub with a comprehensive list of every version of every open source project used by Ingenuity. GitHub could then identify all the contributors who made these projects and their dependencies. Some of those honored, such as Linux's creator Linus Torvalds, are famous developers. Many others labor in obscurity -- but now their work is being recognized. Timothy Canham, a JPL embedded flight software engineer, notes Ingenuity's program is powered by a Qualcomm Snapdragon 801 running at 2.2GHz, which is "far faster than the Mars Perseverance's rover processors," according to ZDNet. The reason this older chip was used is because it meets NASA's High-Performance Spaceflight Computing (HPSC) radiation standards.

Canham also says the flight control software on Ingenuity runs at 500Hz. The flight software "is used to control the flight hardware and read sensors 500 times per second in order to keep the helicopter stable." Canham added: "We literally ordered parts from SparkFun [Electronics]. This is commercial hardware, but we'll test it, and if it works well, we'll use it."

NASA's first attempt to fly its "Ingenuity" helicopter on Mars was a success, marking what the space agency says is the first powered, controlled flight by an aircraft on another world. The BBC reports: The space agency is promising more adventurous flights in the days ahead. Ingenuity will be commanded to fly higher and further as engineers seek to test the limits of the technology. The rotorcraft was carried to Mars in the belly of Nasa's Perseverance Rover, which touched down in Jezero Crater on the Red Planet in February.

The demonstration saw the Mars-copter rise to just over 3m, hover, swivel 96 degrees, hover some more, and then set down. In all, it managed almost 40 seconds of flight, from take-off to landing. Getting airborne on the Red Planet is not easy. The atmosphere is very thin, just 1% of the density here at Earth. This gives the blades on a rotorcraft very little to bite into to gain lift. There's help from the lower gravity at Mars, but still -- it takes a lot of work to get up off the ground. Ingenuity was therefore made extremely light and given the power (a peak power of 350 watts) to turn those blades extremely fast - at over 2,500 revolutions per minute for this particular flight. Control was autonomous. The distance to Mars - currently just under 300 million km -- means radio signals take minutes to traverse the intervening space. Flying by joystick is simply out of the question.

Ingenuity has two cameras onboard. A black-and-white camera that points down to the ground, which is used for navigation, and a high-resolution colour camera that looks out to the horizon. Sample navigation images sent back to Earth revealed the helicopter's shadow on the floor of the crater as it came back in to land. Satellites will send home more pictures of the flight over the next day. There was only sufficient bandwidth in the orbiters' first overflight to return a short snatch of video from Perseverance, which was watching and snapping away from a distance of 65m. Longer sequences should become available in due course.

Slashdot reader quonset reminds us that NASA's Mars helicopter "is officially 'go' for flight!," according to the Twitter feed of the Perserverance Rover, which notes that its cameras are ready to film the historic event.

"Watch with the team as they receive data and find out if they were successful," adds NASA's official feed. "Meet us in mission control April 19 at 6:15am ET (10:15am UTC): Data from the first flight will return to Earth a few hours following the autonomous flight. A livestream will begin at 6:15 a.m. EDT (3:15 a.m. PDT), as the helicopter team prepares to receive the data downlink in the Space Flight Operations Facility at NASA's Jet Propulsion Laboratory (JPL). Watch on NASA Television, the agency app, website, and social media platforms, including YouTube and Facebook.

If the flight takes place April 19, a postflight briefing will be held at 2 p.m. EDT (11 a.m. PDT)...

The public and media also may ask questions on social media during the livestream and briefing using #MarsHelicopter. Find the latest schedule updates here.

The Perseverance rover will provide support during flight operations, taking images, collecting environmental data, and hosting the base station that enables the helicopter to communicate with mission controllers on Earth.
Update: And it's a success! "We've been talking for so long about our Wright Brothers moment on Mars, and here it is," said NASA Ingenuity Mars Helicopter project manager MiMi Aung. The Perserverance rover has already tweeted out a choppy video.

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.

An anonymous reader shares this announcement from NASA: Based on data from the Ingenuity Mars helicopter that arrived late Friday night, NASA has chosen to reschedule the Ingenuity Mars Helicopter's first experimental flight to no earlier than April 14 [this Wednesday].

During a high-speed spin test of the rotors on Friday, the command sequence controlling the test ended early due to a "watchdog" timer expiration. This occurred as it was trying to transition the flight computer from 'Pre-Flight' to 'Flight' mode. The helicopter is safe and healthy and communicated its full telemetry set to Earth.

The watchdog timer oversees the command sequence and alerts the system to any potential issues. It helps the system stay safe by not proceeding if an issue is observed and worked as planned.

The helicopter team is reviewing telemetry to diagnose and understand the issue. Following that, they will reschedule the full-speed test.
