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.

A fully driverless Maserati MC20 Coupe set a new autonomous land speed record, reaching 197.7 mph at the Kennedy Space Center. The Verge reports: The Maserati was running self-driving software developed by Politecnico di Milano, Italy's largest scientific and technological university. The team also worked with the Indy Autonomous Challenge, which most recently ran at the Las Vegas Motor Speedway during CES 2025. In the shadow of NASA's iconic Space Shuttles, the race car flew down the 2.8-mile runway at record-breaking speeds, surpassing the 192.2mph record that was also held by Indy Autonomous Challenge and PoliMOVE, set by an IAC AV-21 race car in April 2022.

The Maserati MC20 is a stylish -- and expensive -- choice for the autonomous run. Retailing for at least $239,000, the race car sports a mid-mounted, twin-turbocharged 3.0-liter V-6 that Maserati calls the Nettuno. The engine makes serious power: 621 horsepower and 538 pound-feet of torque, which is sent through an eight-speed dual-clutch automatic transmission to the rear wheels.

Speaking of some concept devices that Lenovo has unveiled, the company today teased its ThinkBook "codename Flip" AI PC Concept at Mobile World Congress, featuring a flexible 18.1-inch OLED display that can transform between three configurations: a traditional 13.1-inch clamshell, a folded 12.9-inch tablet, or a laptop with an extra-tall vertical screen.

Unlike the motorized ThinkBook Plus Gen 6 expected in June, the Flip uses the display's flexibility to fold behind itself, eliminating motors while gaining 0.4 inches of additional screen space. Users can mirror content on the rear-facing portion when folded or enjoy the full 2000x2664 resolution display in vertical orientation. The concept also features a SmartForcePad trackpad with LED-illuminated shortcut layers. While still in prototype phase, Lenovo has specs in mind: Intel Ultra 7 processor, 32GB RAM, PCIe SSD storage, and Thunderbolt 4 connectivity.

Daniel Parris: Some TV shows take a while to "get good." Modern classics like Breaking Bad, The Wire, Community, and Bojack Horseman are notorious for "starting slow" and are often recommended with a disclaimer like "Give it a few episodes; I promise it gets good!"

At the same time, some shows never get good. Recently, I started a spy series called The Agency, which could best be characterized as premium mediocre (at least so far). There are big-name actors (Michael Fassbender, Jeffrey Wright, Richard Gere), expensive sets, and glossy camerawork -- but after a few installments, I'm trapped in a liminal space between engaged and listless. At the end of each episode, I'm left with the same thought: "Maybe the next one will get good."

Committing to a mediocre program or continuing with a floundering series elicits a state of (mildly) torturous ambiguity. Should you cut your losses, or is this show some late-blooming classic like Breaking Bad? What is the optimal number of episodes one should watch before cleansing a subpar series from their life? Surely, a universal number must exist! Like 42, but for television. So today, we'll explore how long it takes a new show to reach its full potential and how many lackluster episodes you should grant an established series before cutting ties. His analysis reveals that viewers should watch six episodes before quitting TV shows. The study, based on IMDb user ratings, found most series require six to seven episodes before early ratings match or exceed the show's long-term average. After six consecutive subpar episodes, the likelihood of permanent decline exceeds 50%, making it the optimal point to abandon disappointing series.

Several acclaimed shows including Breaking Bad, Friends, and Seinfeld required multiple episodes before reaching their quality potential, with Seinfeld needing 16 episodes to match its series average. The research also identified a pattern where long-running shows typically experience quality decline around seasons five and six, with ratings dropping below first-season averages and continuing to fall.

How confident are we about the safety of commercial space tourism? Long-time Slashdot reader theodp writes: It's one thing for Microsoft to boast that they dare to use Outlook instead of Gmail. But it took a whole other level of commitment for Jeff Bezos to join his brother Mark aboard Blue Origin's first passenger-carrying mission in July 2021.

So, while Bezos is unhesitant about sending himself and other celebrities and loved ones into space aboard Blue Origin, how confident are you about the current state of space travel safety?

If offered a free ride into space from Bezos's Blue Origin, or one of the other options like Virgin Galactic, Axiom Space, or Boeing's Starliner, would you accept or decline it?

Petawatt lasers have already allowed scientists to "manipulate materials in new ways, emulate the conditions inside planets, and even split atoms," reports Science magazine. "Now, accelerator physicists have matched that feat, producing petawatt pulses of electrons that could also have spectacular applications..." Described in a paper published Thursday in Physical Review Letters, the electron pulses last one-quadrillionth of a second but carry 100 kiloamps of current. "It's a supercool experiment," says Sergei Nagaitsev, an accelerator physicist at Brookhaven National Laboratory who was not involved in the work. Richard D'Arcy, a plasma accelerator physicist at the University of Oxford, adds, "It's not just an experimental demonstration of something interesting, it's a steppingstone on the way to megaamp beams." If achievable, those even more powerful beams might begin to perform extraordinary feats such as ripping particles out of empty space, he says...

[A]mped-up lasers would open the way to, for example, probing chemical processes as they happen, says Sergei Nagaitsev [an accelerator physicist at Brookhaven National Laboratory who was not involved in the experiment]. "These are the easy pickings." An ultraintense electron pulse could also be used to generate plasmas like those seen in astrophysics, such as the jets of matter and radiation that shoot out of certain stellar explosions at near-light-speed. Researchers need only fire the electron beam into the right target. "This is a fantastic relativistic drill," Ferrario says. "The interaction of this with matter could be very interesting."

Superintense electron bunches might someday even probe the nature of empty space. They produce a hugely intense electric field, so if one of them were to collide with an ultraintense laser pulse, which also contains a huge electric field, it would expose space to an incredibly strong electrical polarization, D'Arcy notes. If that field is strong enough, it should begin to rip particle-antiparticle pairs out of the vacuum, a phenomenon predicted by quantum physics but never observed. "You can access areas of particle physics that are inaccessible elsewhere," Darcy says.

Watch the "Blue Ghost" lunar lander attempt its moon landing.

The actual landing is scheduled to happen at 3:34 a.m. Eastern time, according to CNN, while "The first images from the mission should be delivered about a half hour after..." Success is not guaranteed... [B]roadly speaking, about half of all lunar landing attempts have ended in failure. Jason Kim, Firefly's CEO, told CNN in December that his company's experience building rockets has given him a high degree of confidence in Blue Ghost's propulsion systems. "We're using (reaction control system) thrusters that we've built, developed in-house, that are designed by the same people that design our rocket engines. That reduces risk," Kim said. "All that gives us high confidence when we have people that do rocket engines really, really well — some of the best in the world."
But the New York Times notes that Blue Ghost, built by Austin, Texas-based Firefly Aerospace, is just one of three robotic spacecraft "in space right now that are aiming to set down on the moon's surface." Blue Ghost has performed nearly perfectly. For the first 25 days, it circled Earth as the company turned on and checked the spacecraft's systems. It then fired its engine on a four-day journey toward the moon, entering orbit on February 13. The spacecraft's cameras have recorded close-up views of the moon's cratered surface...

On the same SpaceX Falcon 9 rocket that launched Blue Ghost to orbit was Resilience, a lunar lander built by Ispace of Japan. The two missions are separate, but Ispace, seeking a cheaper ride to space, had asked SpaceX for a rideshare, that is, hitching a ride as a secondary payload... Although Resilience launched at the same time as Blue Ghost, it is taking a longer, more fuel-efficient route to the moon and is expected to enter orbit around the moon in early May.
The third lunar lander heading to the moon is Athena (from Intuitive Machines), which launched Thursday on a SpaceX Falcon 9 rocket, "marking the first time humanity has had three lunar landers en route to the Moon at the same time," according to a statement from the company. Space.com notes that "To date, just one private spacecraft has ever landed successfully on the moon — Intuitive Machines' Odysseus, which did so in February 2024." Athena launched with several other spacecraft last night, including Odin, a scouting probe built by the asteroid-mining company Astroforge, and NASA's water-hunting Lunar Trailblazer. Lunar Trailblazer is also moon-bound, though it's headed for orbit rather than the surface...

Chinese scientists are developing a lightweight Mars drone capable of both rolling on the ground and flying using contra-rotating coaxial rotors. Space.com reports: The air-ground dual-purpose unmanned aerial vehicle (UAV) weighs only 10.6 ounces (300 grams), equivalent to the weight of an apple. The development team is at the School of Astronautics (SoA) of the Harbin Institute of Technology. Seen as showing promising potential in future Mars science work, the UAV can take off at any time, traverse obstacles, and boasts superb endurance, reports state-owned China Central Television (CCTV).

"On the ground, it mainly rolls by shifting its center of gravity," said Zhu Yimin, a Ph.D candidate at SoA. "In the air, it relies on a pair of contra-rotating coaxial rotors, controlled by a steering engine to adjust the forward direction, to control torque and force, ultimately achieving stable flight," Zhu told CCTV. The UAV work entails multiple models of air-ground dual-mode robots with different configurations, CCTV reports. These robots move by rolling close to the ground, which reduces energy consumption, and can achieve a flight endurance time of more than six times that of traditional drones of the same size.

According to Zhang Lixian, a professor within the SoA, the hope is that the aerial vehicle can show off its long endurance and observational abilities on Mars. "Our second goal is for such machines to be suitable for construction in many underground spaces and for exploring unknown underground spaces. We also need robotic means for inspection and environmental detection. We have now materialized all these functions," said Zhang. A video of the drone can be found here.

Blue Origin on Thursday announced the crew for its next mission. "The crew most notably includes popstar Katy Perry and broadcast journalist Gayle King. They will be joined by two scientists -- Aisha Bowe and Amanda Nguyen -- as well as Jeff Bezos' fiancee, TV personality Lauren Sanchez and film producer Kerianne Flynn," reports TechCrunch. From the report: Blue Origin says this marks the first all-female space crew since Soviet astronaut Valentina Tereshkova's 1963 solo mission, which made her the first woman ever to go to space. For the company's New Shepard rocket, this is its 31st trip to space, and its 11th with a crew. This journey is expected to last around 10 to 12 minutes; and if you're willing to drop a $150,000 deposit, you too can reserve a future spot on a short space jaunt.

Asteroid 2024 YR4, once considered a significant impact risk, has been reassigned to Torino Scale Level Zero and therefore poses no hazard to Earth. "The NASA JPL Center for Near-Earth Object Studies (CNEOS) now lists the 2024 YR4 impact probability as 0.00005 (0.005%) or 1-in-20,000 for its passage by Earth in 2032," Richard Binzel, Professor of Planetary Science at the Massachusetts Institute of Technology (MIT) and creator of the Torino scale exclusively told Space.com. "That's impact probability zero folks!" From the report: Discovered in Dec. 2024, 2024 YR4 quickly climbed to the top of NASA's Sentry Risk table, at one point having a 1 in 32 chance of hitting Earth. This elevated it to Level 3 on the Torino scale, a system used since 1999 to categorize potential Earth impact events. Level 3, which falls within the yellow band of the Torino Scale, is described as: "A close encounter, meriting attention by astronomers. Current calculations give a 1% or greater chance of collision capable of localized destruction."

This conforms to the second part of the Torino scale level 3 description, which states: "Most likely, new telescopic observations will lead to re-assignment to Level 0. Attention by public and by public officials is merited if the encounter is less than a decade away." "Asteroid 2024 YR4 has now been reassigned to Torino Scale Level Zero, the level for 'No Hazard' as additional tracking of its orbital path has reduced its possibility of intersecting the Earth to below the 1-in-1000 threshold," Binzel continued. "1-in-1000 is the threshold established for downgrading to Level 0 for any object smaller than 100 meters; YR4 has an estimated size of 164 feet (50 meters)."

[...] While 2024 YR4 poses no threat, it will still have a major scientific impact when it passes Earth in 2028 and again in 2032. On Dec. 17, the asteroid will come to within 5 million miles of Earth. Then, on Dec.22, 2032, 2024 YR4 will pass within just 167,000 miles of our planet. For context, the moon is 238,855 miles away.

Denmark is set to ban mobile phones in schools and after-school clubs, following a government commission's recommendation that children under 13 should not have their own smartphones. The Guardian reports: The government said it would change existing legislation to force all folkeskole -- comprehensive primary and lower secondary schools -- to become phone-free, meaning that almost all children aged between seven and 16-17 will be required by law not to bring their phones into school. The announcement marks a U-turn by the government, which had previously refused to introduce such a law. It comes as governments across Europe are trying to impose tighter regulations on children's access to phones and social media.

The Danish wellbeing commission was set up by the prime minister, Mette Frederiksen, in 2023 to investigate growing dissatisfaction among children and young people. Its long-awaited report, published on Tuesday, raised the alarm over the digitisation of children and young people's lives and called for a better balance between digital and analogue life. Among its 35 recommendations was the need for government legislation banning phones from schools and after-school clubs.

The minister for children and education, Mattias Tesfaye, told Politiken: "There is a need to reclaim the school as an educational space, where there is room for reflection and where it is not an extension of the teenage bedroom." There will be scope for local authorities to make exceptions, including for children with special educational needs, but he said mobile phones and personal tablets "do not belong in school, neither during breaks nor during lessons." He said the government had started preparing a legislative amendment.

AI-powered search engine Perplexity is developing its own web browser named Comet. "Just like Perplexity reinvented search, we're also reinventing the browser," a Perplexity spokesperson told TechCrunch. "Stay tuned for updates." From the report: In a post on X on Monday, the company launched a sign-up list for the browser, which isn't yet available. It's unclear when it might be -- or what the browser will look like, even. But we do have a name: Comet. [...] Perplexity may be betting that it can leverage its search engine user base to quickly ramp up and make some sort of a dent in the space with Comet.

Long-time Slashdot reader schwit1 shared this observation from space/science news blogger Robert Zimmerman: Having now reached lunar orbit in preparation for its landing on March 2, 2025, an engineering test instrument on Firefly's Blue Ghost lunar lander has now proven that even from that distance spacecraft can use the multiple GPS-type satellites in Earth orbit to track their position.

[From NASA.gov]: The Lunar GNSS Receiver Experiment (LuGRE) acquired and tracked Global Navigation Satellite System (GNSS) signals for the first time in lunar orbit – a new record! This achievement, peaking at 246,000 miles, suggests that Earth-based Global Navigation Satellite System constellations can be used for navigation in transit to, around, and potentially on the Moon. It also demonstrates the power of using multiple GNSS constellations together, such as GPS and Galileo, to perform navigation.

After lunar landing, LuGRE will operate for 14 days and attempt to break another record – first reception of GNSS signals on the lunar surface.

This test is a very big deal. It tells us that operations on the Moon, at least those on the near side, will likely not require a GPS-type infrastructure in lunar orbit, thus allowing a lot of difficult missions to proceed sooner while saving a lot of money and time.

An anonymous reader shared this report from ABC News: Elon Musk called this week for the deorbiting of the International Space Station (ISS) "as soon as possible." "It is time to begin preparations for deorbiting the [ISS]," Musk wrote in a post on X on Thursday. "It has served its purpose. There is very little incremental utility. Let's go to Mars." In a follow-up post, Musk said he was planning to recommend to President Donald Trump that the station be brought down "as soon as possible" and that the 2030 timeline for deorbiting be moved up to two years from now.
Jordan Bimm, space historian and professor of science communication at the University of Chicago, told ABC News what he thinks was one of the most important findings to come out of ISS research: "that microgravity affects the body in lots of deleterious ways." "That leads to your bone loss, muscle loss, changes in the fluid inside our bodies that are normally being pulled down by Earth's gravity, changes to the eye and vision loss and things like that. We have gotten good data on how that progresses over time, and importantly, we have developed countermeasures for these things as well, including resistance training or running on a treadmill, things like that..."

The Washington Post looks at a new kind of battery that "could make American EVs cheaper and safer, experts say." If you bought an EV with a lithium iron phosphate (LFP) battery, you could expect lower car payments, less fire risk and more years of use out of your car — but you wouldn't be able to go as far on a single charge as you could with the nickel manganese cobalt (NMC) batteries commonly found in American and European electric cars. That trade-off has made LFP batteries the go-to choice for standard-range EVs in China, helping to make electric cars more affordable and limit pollution. Now, American companies are starting to build their own LFP batteries to catch up to their Chinese rivals... But there are plenty of barriers for U.S. companies that want to adopt a technology dominated by Chinese firms. Tariffs and tax credit restrictions have made it too expensive for most American automakers to import LFP batteries from China, and national security concerns have made it hard for American companies to partner with Chinese battery makers to build factories in the United States...

Although American scientists invented LFP batteries in 1997, U.S. automakers didn't invest in the technology. Instead, they bet on NMC batteries because they have longer range, a big concern for American EV buyers. "Everyone in the West thought LFP was a nonstarter five or six years ago," said Adrian Yao, who founded STEER, a technology research group within Stanford University. "We really did have a myopic focus on" range, he added. That left the door open for Chinese companies to perfect LFP batteries, which have a few advantages. Instead of pricey nickel and cobalt, they use iron, which makes them 20 percent cheaper than NMC batteries, according to the International Energy Agency. While NMC batteries can be recharged up to about 1,000 times before they go kaput — which is enough to put 200,000 miles on most EVs — LFP batteries can last two or three times as long, according to Moura. Plus, LFP batteries' chemistry makes them less likely to catch fire and easier to extinguish. An NMC battery, on the other hand, is so flammable that "you could put it underwater or in space, and it'll keep burning because the oxygen it needs to keep the flame going is embedded within itself," Moura said.

That safety advantage is key, because Chinese firms figured out they could pack LFP cells closer together inside a battery pack without risking a fire. That meant they could cram more energy into LFP batteries and nearly catch up to the range of NMC batteries. Last year, the Chinese battery giant CATL made the first LFP battery with more than 600 miles of range. Since LFP batteries are made from common materials and last longer, they also have a smaller environmental footprint than NMC batteries.
Ford used LFP batteries in its Mach-E sedan (2023) and F-150 Lightning pickup trucks (2024), according to the article, "while Rivian began using them in the basic trims of its R1S SUV and R1T pickup truck this year... American LFP factories are slated to open this year in St. Louis and next year in Arizona." And an environmental engineering professor at the University of California at Berkeley predicts LFP battery factories in the U.S. will "grow quite rapidly over the next five to 10 years."

The U.S. Space Force released the first-ever public image of its secretive X-37B space plane in orbit, captured during its ongoing seventh mission that launched on December 28, 2023. Space.com reports: The photo, released on Thursday (Feb. 20), was taken by a camera onboard the X-37B while the secretive space plane orbited high above the African continent. One of the plane's solar panels is visible on the left side of the photo, while what appears to be its open payload bay is visible along the top edge. The vehicle has been in orbit for well over a year now, having launched on its seventh mission on Dec. 28, 2023 atop a SpaceX Falcon Heavy rocket.

And now, the X-37B has notched another milestone with the Space Force's release of this photo, the first-ever image of this space plane in orbit that has been shown to the public. While the photo contains scant details about the vehicle and what it's currently testing, it offers a look at Earth far in the background, revealing just how high the vehicle is flying on its seventh mission. We've gotten only one other glimpse at the X-37B in orbit prior to this. During the livestream of its most recent launch, a brief shot of the spacecraft deploying from Falcon Heavy's upper stage was seen while its service module was still attached.

Late Tuesday afternoon, the White House confirmed that it would not proceed with laying off more than 1,000 probationary employees at NASA. "NASA had sought exemptions for all of these employees, who comprise about 6 percent of NASA's workforce," notes Ars Technica. "The Trump administration has sought to fire federal employees at several federal agencies who are in the 'probationary' period of their employment. This includes new hires within the last one or two years or long-time employees who have moved into or been promoted into a new position." From the report: It was not immediately clear why. A NASA spokesperson in Washington, DC, offered no comment on the updated guidance. Two sources indicated that it was plausible that private astronaut Jared Isaacman, whom President Trump has nominated to lead the space agency, asked for the cuts to be put on hold.

Although this could not be confirmed, it seems reasonable that Isaacman would want to retain some control over where cuts at the agency are made. Firing all probationary employees -- which is the most expedient way to reduce the size of government -- is a blunt instrument. It whacks new hires that the agency may have recruited for key positions, as well as high performers who earned promotions.

The reprieve in these terminations does not necessarily signal that NASA will escape significant budget or employment cuts in the coming months. The administration could still seek to terminate probationary employees. In addition, Ars reported earlier that directors at the agency's field centers have been told to prepare options for a "significant" reduction in force in the coming months. The scope of these cuts has not been defined, and it's likely they would need to be negotiated with Congress.

An anonymous reader quotes a report from Ars Technica: Astronomers have detected over 5,800 confirmed exoplanets. One extreme class is ultra-hot Jupiters, of particular interest because they can provide a unique window into planetary atmospheric dynamics. According to a new paper published in the journal Nature, astronomers have mapped the 3D structure of the layered atmosphere of one such ultra-hot Jupiter-size exoplanet, revealing powerful winds that create intricate weather patterns across that atmosphere. A companion paper published in the journal Astronomy and Astrophysics (PDF) reported on the unexpected identification of titanium in the exoplanet's atmosphere as well. [...]

This latest research relied on observational data collected by the European South Observatory's (ESO) Very Large Telescope, specifically, a spectroscopic instrument called ESPRESSO that can process light collected from the four largest VLT telescope units into one signal. The target exoplanet, WASP-121b -- aka Tylos -- is located in the Puppis constellation about 900 light-years from Earth. One year on Tylos is equivalent to just 30 hours on Earth, thanks to the exoplanet's close proximity to its host star. Since one side is always facing the star, it is always scorching, while the exoplanet's other side is significantly colder.

Those extreme temperature contrasts make it challenging to figure out how energy is distributed in the atmospheric system, and mapping out the 3D structure can help, particularly with determining the vertical circulation patterns that are not easily replicated in our current crop of global circulation models, per the authors. For their analysis, they combined archival ESPRESSO data collected on November 30, 2018, with new data collected on September 23, 2023. They focused on three distinct chemical signatures to probe the deep atmosphere (iron), mid-atmosphere (sodium), and shallow atmosphere (hydrogen). "What we found was surprising: A jet stream rotates material around the planet's equator, while a separate flow at lower levels of the atmosphere moves gas from the hot side to the cooler side. This kind of climate has never been seen before on any planet," said Julia Victoria Seidel of the European Southern Observatory (ESO) in Chile and the Observatoire de la Cote d'Azur in France. "This planet's atmosphere behaves in ways that challenge our understanding of how weather works -- not just on Earth, but on all planets. It feels like something out of science fiction."

An anonymous reader shares a report: Later this month, Intuitive Machines, the private company behind the first commercial lander that touched down on the moon, will launch a second lunar mission from NASA's Kennedy Space Center. The plan is to deploy a lander, a rover, and hopper to explore a site near the lunar south pole that could harbor water ice, and to put a communications satellite on lunar orbit. But the mission will also bring something that's never been installed on the moon or anywhere else in space before -- a fully functional 4G cellular network.

Point-to-point radio communications, which need a clear line of sight between transmitting and receiving antennas, have always been a backbone of both surface communications and the link back to Earth, starting with the Apollo program. Using point-to-point radio in space wasn't much of an issue in the past because there never have been that many points to connect. Usually, it was just a single spacecraft, a lander, or a rover talking to Earth. And they didn't need to send much data either. "They were based on [ultra high frequency] or [very high frequency] technologies connecting a small number of devices with relatively low data throughput," says Thierry Klein, president of Nokia Bell Labs Solutions Research, which was contracted by NASA to design a cellular network for the moon back in 2020.
