NASA's SPHEREx observatory (short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) is set to launch this week to map 450 million galaxies in infrared, providing insights into galaxy formation, the origins of water, and testing theories about the universe's rapid expansion following the Big Bang. The two-year mission will repeatedly survey the entire sky and help scientists understand fundamental cosmic processes. NBC News reports: The launch from Vandenberg Space Force Base in California is scheduled to occur Friday, during a window that opens at 10:09 p.m. ET. Liftoff was initially planned for Feb. 27, but NASA rescheduled it several times, first to "complete vehicle processing and prelaunch checkouts," and because of availability at the California launch site.

The cone-shaped spacecraft -- along with four suitcase-sized satellites that NASA will deploy at the same time on a separate mission to study the sun -- will launch atop a SpaceX Falcon 9 rocket. The $488 million SPHEREx mission, which has been in development for about a decade, is designed to map the celestial sky in 102 infrared colors -- more than any other mission before it, according to NASA.

The Athena lunar lander from Intuitive Machines has prematurely ended its mission after tipping onto its side shortly after touching down near the moon's south pole, failing to fully accomplish its planned water-searching objectives. From a report: Athena was expected to operate for about 10 days before powering down as lunar night fell over the spacecraft's landing site at Mons Mouton, a plateau that lies about 100 miles (160 kilometers) from the south pole. But photographs delivered by the lander before it powered down confirmed the vehicle is lying on its side. "With the direction of the sun, the orientation of the solar panels, and extreme cold temperatures in the crater, Intuitive Machines does not expect Athena to recharge," the company said in a statement. "The mission has concluded and teams are continuing to assess the data collected throughout the mission."

Intuitive Machines, however, highlighted that, although Athena did not operate as intended, the lander was able to briefly operate and transmit data after touchdown. That made the mission the "southernmost lunar landing and surface operations ever achieved." Intuitive Machines also said that Athena was "able to accelerate several program and payload milestones, including NASA's PRIME-1 suite, before the lander's batteries depleted." PRIME-1, which includes a drill that was expected to dig into the lunar surface to hunt for water, was able to move, according to a statement from NASA that states the device "demonstrated the hardware's full range of motion in the harsh environment of space."

An anonymous reader quotes a report from The Guardian: Many of us have been guilty of binning a mushy, overripe banana -- but now scientists say they have a solution with the launch of a genetically engineered non-browning banana. The product is the latest in a series of gene-edited fruits and vegetables designed to have a longer shelf life. Scientists say the technology is emerging as a powerful new weapon against food waste, which occurs globally on an epic scale. The banana, developed by Tropic, a biotech company based in Norwich, is said to remain fresh and yellow for 12 hours after being peeled and is less susceptible to turning brown when bumped during harvesting and transportation.

The company has also developed a slow-ripening banana that has been approved in several countries, which it plans to launch later in the year. Other research teams are working on lettuce that wilts more slowly, bruise-resistant apples and potatoes and identifying the genes that determine how quickly grapes and blueberries shrivel. [...] The company worked out how to disable a gene responsible for the production of an enzyme called polyphenol oxidase, which causes browning. The same gene is silenced in Arctic apples, a genetically modified variety, which has been sold in the US since 2017, and blocking the production of polyphenol oxidase has been shown to work in tomatoes, melon, kiwifruits and mushrooms. In the bananas, Tropic made precise changes to existing genes without introducing foreign genetic material. The report notes that an estimated 33% of the produce that is harvested worldwide is never consumed due to the short shelf-life of many fruit and vegetable products. Bananas are among the most thrown-away foods, with some 5 billion bananas tossed in the U.S. each year.

PhD students trained in small research groups are more likely to remain in academia than those from larger labs, according to a comprehensive analysis published in Nature Human Behaviour.

The study, which examined 1.5 million scientists and 1.8 million mentorships across chemistry, physics and neuroscience, found that trainees from large research groups had 38-48% lower "survival rates" in academia between the 1980s and 1995 compared to their small-group counterparts.

However, researchers from larger labs who do stay in academia tend to achieve greater career success, publishing papers with higher citation rates and more frequently ranking among the most-cited scientists.

The research team, led by social-data scientist Roberta Sinatra from the University of Copenhagen, discovered that successful large-group scientists typically published more first-author papers with their mentors as last authors, suggesting they received substantial attention despite the group size.

Intuitive Machines' Athena lander touched down near the lunar south pole Thursday but may have toppled during landing, jeopardizing its scientific mission. "We're trying to evaluate exactly what happened in that last bit," said Tim Crain, Intuitive Machines' chief technology officer. Data from an inertial measurement unit suggests the 15-foot robotic spacecraft is lying on its side.

The landing issues mirror problems faced by the company's Odysseus spacecraft last year, which also toppled after touchdown. Noisy data from laser altitude instruments likely contributed to the landing complications, officials said. CEO Steve Altemus reported the spacecraft isn't generating expected power, probably because its solar panels are improperly oriented. The company believes Athena landed somewhere on Mons Mouton, though outside the planned landing zone.

The $62.5 million NASA-contracted mission carries several payloads, including a drill to search for frozen water, three small rovers, and a rocket-powered hopping drone. NASA officials indicated some experiments might still function despite the lander's orientation. Intuitive Machines' stock fell 20% Thursday following reports of the spacecraft's problems.

UPDATE: Athena Spacecraft Declared Dead After Toppling Over On Moon

SpaceX's eighth Starship test flight ended in failure after losing control and breaking apart shortly after launch, sending debris over Florida. "Starship didn't make it quite as high or as far" as the attempt nearly two months ago," notes NPR. That attempt ended with an explosion that sent flaming debris raining down on the Turks and Caicos. From the report: This time, wreckage from the latest explosion was seen streaming from the skies over Florida. It was not immediately known whether the spacecraft's self-destruct system had kicked in to blow it up. The 403-foot rocket blasted off from Texas. SpaceX caught the first-stage booster back at the pad with giant mechanical arms, but engines on the spacecraft on top started shutting down as it streaked eastward for what was supposed to be a controlled entry over the Indian Ocean, half a world away. Contact was lost as the spacecraft went into an out-of-control spin.

Starship reached nearly 90 miles in altitude before trouble struck and before four mock satellites could be deployed. It was not immediately clear where it came down, but images of flaming debris were captured from Florida, including near Cape Canaveral, and posted online. The space-skimming flight was supposed to last an hour. "Unfortunately this happened last time too, so we have some practice at this now," SpaceX flight commentator Dan Huot said from the launch site. SpaceX later confirmed that the spacecraft experienced "a rapid unscheduled disassembly" during the ascent engine firing. "Our team immediately began coordination with safety officials to implement pre-planned contingency responses," the company said in a statement posted online.

NASA has begun shutting down science instruments aboard the twin Voyager spacecraft to extend their 47-year journey through interstellar space, officials said. Voyager 1's cosmic ray subsystem was deactivated on February 25, while Voyager 2's low-energy charged particle instrument will be shut down on March 24. Both spacecraft will then operate with just three of their original ten science instruments.

The radioisotope power systems aboard the Voyagers lose approximately 4 watts annually, threatening to end their mission within months without intervention. "Electrical power is running low," said Voyager project manager Suzanne Dodd. "The Voyagers have been deep space rock stars since launch, and we want to keep it that way as long as possible." NASA engineers believe these measures could enable the probes to continue operating into the 2030s, far beyond their initial five-year design life.

Geoffrey.landis writes: Over the last three months of 2024, more than 800 cases of GPS interference were recorded in Lithuanian airspace. Estonia and Finland have also raised concerns, accusing Russia of deploying technology to jam satellite navigation signals near Nato's eastern flank.

A group of British scientists -- dubbed the "Time Lords" -- are working on a solution: to develop portable atomic clocks. By carrying a group of atoms cooled to -273C on the plane itself, rather than relying on an external signal, the technology can't be interfered with by jamming. But the problem is that the equipment is still too large to be used routinely on planes.

The UK Hub for Quantum Enabled Position Navigation and Timing (QEPNT) was set up last December by the government to shrink the devices on to a chip, making them robust enough for everyday life and affordable for everyone. Henry White, part of the team from BAE Systems that worked on the test flight, told BBC News that he thought the first application could be aboard ships, "where there's a bit more space".

An anonymous reader quotes a report from Popular Science: On March 2, Firefly Aerospace's Blue Ghost made history, becoming the first commercial lunar lander to successfully touchdown on the moon's surface. The groundbreaking lander is wasting no time in getting to work. According to NASA, the joint public-private mission has already successfully demonstrated the ability to use Earth-based GPS signals on the lunar surface, marking a major step ahead of future Artemis missions. Accurate and reliable navigation will be vital for future astronauts as they travel across the moon, but traditional GPS tools aren't much good when you're around 225,000 miles from Earth. One solution could be transmitting data from the Global Navigation Satellite System (GNSS) to the lunar surface in order to autonomously measure time, velocity, and position. That's what mission engineers from NASA and the Italian Space Agency hoped to demonstrate through the Lunar GNSS Receiver Experiment (LuGRE), one of the 10 projects packed aboard Blue Ghost. [...]

"On Earth we can use GNSS signals to navigate in everything from smartphones to airplanes," Kevin Coggins, deputy associate administrator for NASA's SCaN (Space Communications and Navigation) Program, said in a statement. "Now, LuGRE shows us that we can successfully acquire and track GNSS signals at the Moon." LuGRE relied on two GNSS constellations, GPS and Galileo, which triangulate positioning based on dozens of medium Earth orbit satellites that provide real-time tracking data. It performed its navigational fix at approximately 2 a.m. EST on March 3, while about 225,000 miles from Earth. Blue Ghost's LuGRE system will continue collecting information over the next two weeks almost continuously while the lander's other tools begin their own experiments.

Australian company Cortical Labs has launched the CL1, the world's first commercial "biological computer" that merges human brain cells with silicon hardware to form adaptable, energy-efficient neural networks. New Atlas reports: Known as a Synthetic Biological Intelligence (SBI), Cortical's CL1 system was officially launched in Barcelona on March 2, 2025, and is expected to be a game-changer for science and medical research. The human-cell neural networks that form on the silicon "chip" are essentially an ever-evolving organic computer, and the engineers behind it say it learns so quickly and flexibly that it completely outpaces the silicon-based AI chips used to train existing large language models (LLMs) like ChatGPT.

"Today is the culmination of a vision that has powered Cortical Labs for almost six years," said Cortical founder and CEO Dr Hon Weng Chong. "We've enjoyed a series of critical breakthroughs in recent years, most notably our research in the journal Neuron, through which cultures were embedded in a simulated game-world, and were provided with electrophysiological stimulation and recording to mimic the arcade game Pong. However, our long-term mission has been to democratize this technology, making it accessible to researchers without specialized hardware and software. The CL1 is the realization of that mission." He added that while this is a groundbreaking step forward, the full extent of the SBI system won't be seen until it's in users' hands.

"We're offering 'Wetware-as-a-Service' (WaaS)," he added -- customers will be able to buy the CL-1 biocomputer outright, or simply buy time on the chips, accessing them remotely to work with the cultured cell technology via the cloud. "This platform will enable the millions of researchers, innovators and big-thinkers around the world to turn the CL1's potential into tangible, real-word impact. We'll provide the platform and support for them to invest in R&D and drive new breakthroughs and research." These remarkable brain-cell biocomputers could revolutionize everything from drug discovery and clinical testing to how robotic "intelligence" is built, allowing unlimited personalization depending on need. The CL1, which will be widely available in the second half of 2025, is an enormous achievement for Cortical -- and as New Atlas saw recently with a visit to the company's Melbourne headquarters -- the potential here is much more far-reaching than Pong.

EmagGeek shares a report: Scientists have genetically engineered mice with some key characteristics of an extinct animal that was far larger -- the woolly mammoth. This "woolly mouse" marks an important step toward achieving the researchers' ultimate goal -- bringing a woolly mammoth-like creature back from extinction, they say.

"For us, it's an incredibly big deal," says Beth Shapiro, chief science officer at Colossal Biosciences, a Dallas company trying to resurrect the woolly mammoth and other extinct species. The company announced the creation of the woolly mice Tuesday in a news release and posted a scientific paper online detailing the achievement. Scientists implanted genetically modified embryos in female lab mice that gave birth to the first of the woolly pups in October.

My editorial: One has to wonder why it is necessary or even a great idea to bring back species that nature long ago determined were a failure.

AmiMoJo shares a report: Europe's biggest battery storage project has entered commercial operation in Scotland [alternative source], promising to soak up surplus wind power and prevent turbines being paid to switch off.

Zenobe said the first phase of its project at Blackhillock, between Inverness and Aberdeen, was now live with capacity to store enough power to supply 200 megawatts of electricity for two hours. It is due to be expanded to 300 megawatts by next year, enough to supply 3.1 million homes, more than every household in Scotland.

The government's Clean Power 2030 action plan sets a target capacity of up to 27 gigawatts of batteries by 2030, a sixfold increase from the 4.5 gigawatts installed today. This huge expansion is seen as critical as Britain builds more renewable wind and solar power, since batteries can store surplus generation for use when the wind does not blow and the sun does not shine.

China's highest court has called for a crack down on the activities of paper mills, businesses that churn out fraudulent or poor-quality manuscripts and sell authorships. Nature: Some researchers are cautiously optimistic that the court's guidance will help curb the use of these services, while others think the impact will be minimal. "This is the first time the supreme court has issued guidance on paper mills and on scientific fraud," says Wang Fei, who studies research-integrity policy at Dalian University of Technology in China.

Paper mills sell suspect research and authorships to researchers who want journal articles to burnish their CVs. They are a significant contributor to overall research misconduct, particularly in China. Last month, the Supreme People's Court published a set of guiding opinions on technology innovation. Among the list of 25 articles, one called for lower courts to crack down on 'paper industry chains,' and for research fraud to be severely punished. Further reading:

Firefly Aerospace's Blue Ghost lander successfully touched down on the moon, making it the first private company to achieve a stable lunar landing without crashing. The craft is carrying various NASA-funded experiments, including a "vacuum to suck up moon dirt for analysis and a drill to measure temperature as deep as 10 feet (3 meters) below the surface," reports the Associated Press. There's also "a device for eliminating abrasive lunar dust -- a scourge for NASA's long-ago Apollo moonwalkers, who got it caked all over their spacesuits and equipment." From the report: A half hour after landing, Blue Ghost started to send back pictures from the surface, the first one a selfie somewhat obscured by the sun's glare. The second shot included the home planet, a blue dot glimmering in the blackness of space. Blue Ghost -- named after a rare U.S. species of fireflies -- had its size and shape going for it. The squat four-legged lander stands 6-foot-6 (2 meters) tall and 11 feet (3.5 meters) wide, providing extra stability, according to the company.

Launched in mid-January from Florida, the lander carried 10 experiments to the moon for NASA. The space agency paid $101 million for the delivery, plus $44 million for the science and tech on board. It's the third mission under NASA's commercial lunar delivery program, intended to ignite a lunar economy of competing private businesses while scouting around before astronauts show up later this decade.

Firefly's Ray Allensworth said the lander skipped over hazards including boulders to land safely. Allensworth said the team continued to analyze the data to figure out the lander's exact position, but all indications suggest it landed within the 328-foot (100-meter) target zone in Mare Crisium. The demos should get two weeks of run time, before lunar daytime ends and the lander shuts down.

NASA used specialized Schlieren photography to capture an image of Boom Supersonic's XB-1 demonstrator aircraft breaking the sound barrier on February 10, 2025 and producing shock waves as it exceeded Mach 1. The flight produced no audible sonic boom, marking progress toward the goal of quiet supersonic travel. CNN reports: "This image makes the invisible visible," said Blake Scholl, founder and CEO of Boom Supersonic, in a press release. In order to capture the Schlieren images, Boom chief test pilot Tristan "Geppetto" Brandenburg positioned XB-1 at an exact time in a precise location over the Mojave Desert.

As the aircraft flew in front of the sun, NASA's team documented the changing air speeds as speeds over Mach 1, the speed of sound (761.23 miles per hour or 1,225.1 kilometers per hour). The images were captured during ground telescopes with special filters that detect air distortions. You can view the photo here.
