Which country will shoot the first movie in outer space? Russia is now "in a race with the United States to claim the achievement," reports NBC News.

36-year-old actress Yulia Peresild and 37-year-old director Klim Shepenko will complete Russia's cosmonaut-training program, ultimately taking two of the three seats aboard the October launch of Russia's Soyuz mission to the International Space Station: The Russian space agency, Roscosmos, announced Thursday that it had selected its crew to headline the film, which will be called "Challenge..."

Very little is known about the plot, which in many ways seems secondary to the spectacle. When Russia announced the project last year, Konstantin Ernst, the head of Russia's Channel One — which is working with Roscosmos on the film — said that it would not be a science fiction film, but a realistic depiction of near-term space travel. "It's a movie about how a person in no way connected with space exploration, due to various reasons and personal debt, ends up a month later in orbit," Ernst said in a September 2020 interview. "That's all I can tell you...."

The decision to fill the October Soyuz flight with a movie crew comes at an uncertain time for Russia's space program... In October, NASA paid for its final flight aboard Soyuz... Russia is now left to look for other means to help subsidize launch costs. One of those obvious sources — beyond funding from the state television network Channel One — is space tourism. Another Soyuz will launch in December, and rather than fill those seats with Russian cosmonauts, Moscow announced Thursday that two Japanese space tourists will take the ride.

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.

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.

NASA engineers are getting one last look at the James Webb Space Telescope (JWST): a final test to show that its 18 gold-tinted mirror segments can unfold into a precise honeycomb configuration. From a report: After the test concludes this week, the giant instrument will be folded up, packed into a shipping container, and shipped off to French Guiana, where it will launch into space on 31 October. The 6.5-meter-wide JWST is the agency's next great observatory, the successor to the Hubble Space Telescope.

In a NASA briefing this week, Program Scientist Eric Smith told reporters it was born out of a realization in the mid-1990s that, no matter how long it stared into deep space, Hubble would never be able to see the universe's very first stars and galaxies and learn how they formed and evolved. The expanding universe has "redshifted" the light of those primordial objects out of the visible spectrum; NASA needed a space telescope that worked in the infrared. "So the idea of Webb was born," Smith says. Since then, astronomers have discovered thousands of exoplanets. Smith says JWST will be able to probe their atmospheres for molecules such as carbon dioxide, water, methane, and others that could suggest the presence of life.

Getting the $9 billion contraption to the point of departure has taken NASA much more time and money than it or Congress ever suspected. The construction of JWST proved to be the most complex and difficult science project in the agency's history. The process of testing the telescope's folding mirror, multilayered sunshield, and cryogenically cooled instruments has stretched years longer than planned. But come late August, all that will be over as JWST, in a protective cocoon, will be taken from Northrop Grumman's facility in Redondo Beach, California, and put onto a ship. The telescope will sail through the Panama Canal to Europe's spaceport near Kourou. Unlike the 2.4-meter-wide Hubble, which fit comfortably inside the bay of the Space Shuttle, JWST's mirror is much larger than the fairing on top of an Ariane 5 rocket, so it is elaborately folded to fit inside it.

Obipale shares a press release from NASA: After nearly five years in space, NASA's Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) spacecraft is on its way back to Earth with an abundance of rocks and dust from the near-Earth asteroid Bennu. On Monday, May 10, at 4:23 p.m. EDT the spacecraft fired its main engines full throttle for seven minutes -- its most significant maneuver since it arrived at Bennu in 2018. This burn thrust the spacecraft away from the asteroid at 600 miles per hour (nearly 1,000 kilometers per hour), setting it on a 2.5-year cruise towards Earth. After releasing the sample capsule, OSIRIS-REx will have completed its primary mission. It will fire its engines to fly by Earth safely, putting it on a trajectory to circle the sun inside of Venus' orbit. After orbiting the Sun twice, the OSIRIS-REx spacecraft is due to reach Earth Sept. 24, 2023. Upon return, the capsule containing pieces of Bennu will separate from the rest of the spacecraft and enter Earth's atmosphere. The capsule will parachute to the Utah Test and Training Range in Utah's West Desert, where scientists will be waiting to retrieve it.

"OSIRIS-REx's many accomplishments demonstrated the daring and innovate way in which exploration unfolds in real time," said Thomas Zurbuchen, associate administrator for science at NASA Headquarters. "The team rose to the challenge, and now we have a primordial piece of our solar system headed back to Earth where many generations of researchers can unlock its secrets." To realize the mission's multi-year plan, a dozen navigation engineers made calculations and wrote computer code to instruct the spacecraft when and how to push itself away from Bennu. After departing from Bennu, getting the sample to Earth safely is the team's next critical goal. This includes planning future maneuvers to keep the spacecraft on course throughout its journey.

Obipale shares a report from Phys.Org: Voyager 1 -- one of two sibling NASA spacecraft launched 44 years ago and now the most distant human-made object in space -- still works and zooms toward infinity. The craft has long since zipped past the edge of the solar system through the heliopause -- the solar system's border with interstellar space -- into the interstellar medium. Now, its instruments have detected the constant drone of interstellar gas (plasma waves), according to Cornell University-led research published in Nature Astronomy.

Examining data slowly sent back from more than 14 billion miles away, Stella Koch Ocker, a Cornell doctoral student in astronomy, has uncovered the emission. "It's very faint and monotone, because it is in a narrow frequency bandwidth," Ocker said. "We're detecting the faint, persistent hum of interstellar gas." This work allows scientists to understand how the interstellar medium interacts with the solar wind, Ocker said, and how the protective bubble of the solar system's heliosphere is shaped and modified by the interstellar environment.

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."

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.

NASA has suspended work on SpaceX's new $2.9 billion lunar lander contract while a federal watchdog agency adjudicates two protests over the award, the agency said Friday. The Verge reports: Putting the Human Landing System (or HLS) work on hold until the GAO makes a decision on the two protests means SpaceX won't immediately receive its first chunk of the $2.9 billion award, nor will it commence the initial talks with NASA that would normally take place at the onset of a major contract. Elon Musk's SpaceX was picked by NASA on April 16th to build the agency's first human lunar lander since the Apollo program, as the agency opted to rely on just one company for a high-profile contract that many in the space industry expected to go to two companies.

As a result, two companies that were in the running for the contract, Blue Origin and Dynetics, protested NASA's decision to the Government Accountability Office, which adjudicates bidding disputes. Blue Origin alleges the agency unfairly "moved the goalposts at the last minute" and endangered NASA's speedy 2024 timeline by only picking SpaceX. "Pursuant to the GAO protests, NASA instructed SpaceX that progress on the HLS contract has been suspended until GAO resolves all outstanding litigation related to this procurement," NASA spokeswoman Monica Witt said in a statement.

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.

Astronomers reconstructed a space rock's path before it exploded over southern Africa in 2018 and sprinkled the Kalahari with meteorites. From a report: On the morning of June 2, 2018, an asteroid was seen careening toward us at 38,000 miles per hour. It was going to impact Earth, and there was nothing anyone could do to stop it. Astronomers were beside themselves with excitement. Five feet long and weighing about the same as an adult African elephant, this space rock posed no threat. But the early detection of this asteroid, only the second to be spotted in space before hitting land, was a good test of our ability to spot larger, more dangerous asteroids. Moreover, it afforded scientists the chance to study the asteroid before its obliteration, quickly narrow down the impact site and obtain some of the most pristine, least weathered meteorite samples around. Later that day, a fireball almost as bright as the sun illuminated Botswana's darkened sky before exploding 17 miles above ground with the force of 200 tons of TNT. Fragments fell like extraterrestrial buckshot into a national park larger than the Netherlands.

Immediately, Botswanan scientists and guides joined with international meteorite experts to hunt for the asteroid's wreckage. As of November 2020, the team has found 24 individual meteorites. And thanks to the telltale geology of these rocky leftovers, observations of their path to Earth and the memories of a dead NASA spacecraft, scientists were able to unspool the history of this asteroid with breathtaking detail. As reported earlier this month in the journal Meteoritics & Planetary Science, Botswana's off-world visitor was once part of Vesta, a gigantic ramshackle asteroid forged at the dawn of the solar system. About 22 million years ago, another asteroid crashed into one of its lonely hills, leaving a modest crater and sending countless shards of Vesta on a space odyssey. One of them was the object that fell over southern Africa in 2018, an explosive end to a lonely journey. 'It is such an amazing thing to be in possession of such a rare specimen with so much history attached to it," said Mohutsiwa Gabadirwe, a geologist and curator at the Botswana Geoscience Institute who is a co-author.

Named 2018 LA, the asteroid was first seen by the Catalina Sky Survey, a trio of telescopes north of Tucson, Ariz. Additional telescopes, like the SkyMapper Southern Sky Survey, saw it too, allowing scientists to tentatively map out an impact site in southern Africa. Peter Jenniskens, a meteorite expert at the SETI Institute and study author, said that the initial search area was a 1,400-square-mile patch in Botswana. Hoping to shrink it down, he visited local businesses with Oliver Moses of the Okavango Research Institute. They located security camera footage at a hotel and gas stations that had recorded the fireball, allowing them to more precisely pinpoint the fall site: a (still-sizable) spot within the Central Kalahari Game Reserve. This was a surreal place to go meteorite hunting. Bat-eared foxes and warthogs strolled past, lions stealthily stalked and slaughtered giraffes while leopards lounged in trees. Wardens from Botswana's Department of Wildlife and National Parks protected the search party in case a fanged predator got too close for comfort. The meteorites also looked a lot like animal poop, meaning the team were frequently bamboozled by coprological impostors. 'It was a totally unusual experience for all of us,' said Mr. Gabadirwe.

An astronaut who flew on one of the most famous space missions of all time has died. From a report: Michael Collins, 90, was part of the three-member crew on Apollo 11, the first lunar landing mission in 1969. Unlike Neil Armstrong and Buzz Aldrin, he never walked on the moon. Collins stayed behind and piloted the command module as it circled above. Because of that, Collins is often called the 'forgotten astronaut'. Collins had been battling cancer. In a statement released by his family, "He spent his final days peacefully, with his family by his side. Mike always faced the challenges of life with grace and humility, and faced this, his final challenge in the same way."

NASA Administrator Steve Jurczyk said the nation lost a true pioneer, "NASA mourns the loss of this accomplished pilot and astronaut, a friend of all who seek to push the envelope of human potential. Whether his work was behind the scenes or on full view, his legacy will always be as one of the leaders who took America's first steps into the cosmos. And his spirit will go with us as we venture toward farther horizons." When Neil Armstrong first stepped on the moon and uttered the famous phrase, "Houston, Tranquility Base here, the Eagle has landed," Collins was in orbit, 60 miles above, just as busy, and just as excited, telling the team back in Houston he was listening to communications with his comrades, and it was "fantastic." Aldrin and Armstrong were on the lunar surface just under 22 hours. The world was transfixed. Seeing them bunny-hop along, take pictures and collect lunar samples during their single, short moonwalk. All the while, Collins circled the moon. Looking down at the barren lunar landscape and peering back at the Earth. "The thing I remember most is the view of planet Earth from a great distance," he said later. "Tiny. Very shiny. Blue and white. Bright. Beautiful. Serene and fragile."

"Jeff Bezos' Blue Origin filed a protest with the Government Accountability Office against NASA on Monday, challenging the space agency's award of a nearly $3 billion moon lander contract to Elon Musk's SpaceX earlier this month," reports CNBC. In response, Musk teased on Twitter that Bezos couldn't "get it up (to orbit)." From the report: SpaceX, in a competition against Blue Origin and Leidos' subsidiary Dynetics, was awarded $2.89 billion for NASA's Human Landing System program. The HLS program is focused on building a lunar lander that can carry astronauts to the moon's surface under NASA's Artemis missions. For HLS, SpaceX bid a variation of its Starship rocket, prototypes of which the company has been testing at its facility in Texas. NASA was previously expected to choose two of the three teams to competitively build lunar landers, making the sole selection of SpaceX a surprise given the agency's prior goals for the program to continue to be a competition.

Blue Origin decried the award as "flawed" in a statement to CNBC, saying that NASA "moved the goalposts at the last minute." "In NASA's own words, it has made a 'high risk' selection. Their decision eliminates opportunities for competition, significantly narrows the supply base, and not only delays, but also endangers America's return to the Moon. Because of that, we've filed a protest with the GAO," Blue Origin said. Blue Origin revealed that NASA evaluated the company's HLS proposal to cost $5.99 billion, or roughly twice that of SpaceX. The company argued in its protest filing that NASA's cost for funding both proposals would have been under $9 billion -- or near how much the agency spent for SpaceX and Boeing to develop competing astronaut capsules under the Commercial Crew program.

First, Bezos' company said NASA did not give SpaceX's competitors an opportunity to "meaningfully compete" after "the agency's requirements changed due to its undisclosed, perceived shortfall of funding" for the HLS program. Second and third, Blue Origin said that NASA's acquisition was flawed under the agency's acquisition rules and its evaluation of the company's proposal "unreasonable." Fourth, the company asserted that NASA "improperly and disparately" evaluated SpaceX's proposal. And finally, Blue Origin said that NASA's evaluation of the proposals changed the weight it gave to key criteria, making price "the most important factor because of perceived funding limitations."

"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.

Technology/space pundit Robert Cringely writes that SpaceX's winning bid on NASA's Artemis lunar lander contract was helped by its flexibility in how it would be paid — made possibly by SpaceX's cushy financial position.

But he believes that's part of a larger story about SpaceX's "steadily crushing its competitors by building a hyper-efficient space ecosystem where the other guys are just building rockets," arguing that SpaceX has already won the global war of ISPs "at a net cost of ZERO dollars," if not a negative net cost, while realizing a dream of a satellite internet service that for 30 years has eluded investors like Bill Gates:

SpaceX making a profit where one would not normally exist comes thanks to U.S. residents who pay telephone and Internet bills. The U.S. Federal Communications Commission (FCC) has been socking-away for a decade about $1.8 billion per year from you and me, saving-up to pay for expansions of rural telephony and broadband. There is now about $16 billion in this federal kitty and the FCC is starting to spend it with telephone and internet service providers, paying them to extend broadband and voice services to remote rural users who are presently underserved or unserved completely. All of this is both perfectly legal and even a good idea. Everybody wins. But circumstances are turning out to indicate that SpaceX is probably winning more than anyone else... So far SpaceX has won auctions for service in parts of 35 states for a total of $885 million... SpaceX just bid for potential customers in places where other companies typically didn't even bother to bid. They took the obvious remote customers and apparently won't be over-charging them or the government, either...

There is no FCC rule saying Comcast couldn't sub-contract...difficult customers to Starlink... Instead of earning $885 million of those FCC subsidies, Starlink is more likely to gain half of the full $9.2 billion — money that can be used for any purpose including financing that Artemis lander. But remember that satellites are a global resource. If SpaceX launches 4000 or 12,000 Starlink satellites to serve the USA, they'll also serve anywhere else the satellites overfly, even North Korea. The same level of service Starlink offers in Omaha will be available in Vietnam or on tankers in the Pacific ocean.

Once Starlink becomes effectively the dominant ISP in America, it will also become the dominant ISP in the world. And all at no cost to SpaceX since the expansion will have been financed from our phone bills.
Cringely cites estimates that 40,000 satellites would be enough to serve every Internet user on Earth, as well as IoT devices and even future as-yet-uninvented network services.

He also asks whether this might ultimately make it harder for China to censor the internet — and whether Apple might attempt a competing satellite-to-phone network, possibly using technology from Samsung.

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.

What do you call a collection of black holes? The question has taken on an urgency among astronomers inspired by the recent news of dozens of black holes buzzing around the center of a nearby cluster of stars. The New York Times: In the last few years, instruments like the LIGO and Virgo gravitational-wave detectors have recorded space-time vibrations from the collisions of black holes, making it clear beyond doubt that these monstrous concentrations of nothingness not only exist but are ubiquitous. Astronomers anticipate spotting a great number of these Einsteinian creatures when the next generation of gravitational-wave antennas are deployed. What will they call them? There are gaggles of geese, pods of whales and murders of crows. What term would do justice to the special nature of black holes? A mass? A colander? A scream?

Jocelyn Kelly Holley-Bockelmann, an astrophysicist at Vanderbilt University, and colleagues are developing an international project called the Laser Interferometer Space Antenna, or LISA, that will be able to detect collisions between all sizes of black holes throughout the universe. She was trying to run a Zoom meeting of the group recently "when one of the members said his daughter was wondering what you call a collective of black holes -- and then the meeting fell apart, with everyone trying to up one another," she said in an email. "Each time I saw a suggestion, I had to stop and giggle like a loon, which egged us all on more." The question was crowdsourced on Twitter recently as part of what NASA has begun calling black hole week (April 12-16). Among the many candidates so far: A crush. A mosh pit. A silence. A speckle. A hive. An enigma. Or a favorite of mine for of its connection to my youth: an Albert Hall of black holes.

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.
