"The huge parachute used by NASA's Perseverance rover to land on Mars contained a secret message," reports the Associated Press — thanks to the rover's puzzle-loving systems engineer Ian Clark.

"During a live stream discussing the landing, one Nasa commentator said: 'Sometimes we leave messages in our work for others to find. So we invite you all to give it a shot and show your work,'" reports the Guardian.

One Reddit user actually deciphered the message using Python code.

Long-time Slashdot reader rufey writes that "Decoded the slogan is 'Dare Mighty Things' — a line from President Theodore Roosevelt — which is a mantra at JPL and adorns many of the center's walls." The orange sections of the 70-foot (21-meter) parachute represented ones in binary code, while the yellow sections represented zeroes. (So the letter "A" becomes yellow-yellow-yellow-yellow-yellow-yellow-orange...) The Associated Press reports: Clark also included the GPS coordinates for the mission's headquarters at the Jet Propulsion Laboratory in Pasadena, California. Clark, a crossword hobbyist, came up with the idea two years ago. Engineers wanted an unusual pattern in the nylon fabric to know how the parachute was oriented during descent. Turning it into a secret message was "super fun," he said Tuesday. Only about six people knew about the encoded message before Thursday's landing, according to Clark. They waited until the parachute images came back before putting out a teaser during a televised news conference Monday...

Another added touch not widely known until touchdown: Perseverance bears a plaque depicting all five of NASA's Mars rovers in increasing size over the years — similar to the family car decals seen on Earth.

Deputy project manager Matt Wallace promises more so-called hidden Easter eggs...
The official Twitter feed for the rover has already revealed that it's carrying another message hidden in a plaque with a logo of the sun — "Explore as One," written in Morse code.

Some other interesting facts about the rover:

• NASA points out that Perseverance carried a special placard with 10,932,295 names, "stenciled by electron beam onto three fingernail-sized silicon chips."

• Space.com notes that it also carried a small aluminum plate honoring the healthcare workers of the world.

• NASA is encouraging children to code their own version of the helicopter using the visual programming language Scratch.

New video from NASA's Mars 2020 Perseverance rover chronicles major milestones during the final minutes of its entry, descent, and landing (EDL) on the Red Planet on Feb. 18 as the spacecraft plummeted, parachuted, and rocketed toward the surface of Mars. A microphone on the rover also has provided the first audio recording of sounds from Mars. From a report: From the moment of parachute inflation, the camera system covers the entirety of the descent process, showing some of the rover's intense ride to Mars' Jezero Crater. The footage from high-definition cameras aboard the spacecraft starts 7 miles (11 kilometers) above the surface, showing the supersonic deployment of the most massive parachute ever sent to another world, and ends with the rover's touchdown in the crater. A microphone attached to the rover did not collect usable data during the descent, but the commercial off-the-shelf device survived the highly dynamic descent to the surface and obtained sounds from Jezero Crater on Feb. 20. About 10 seconds into the 60-second recording, a Martian breeze is audible for a few seconds, as are mechanical sounds of the rover operating on the surface. "For those who wonder how you land on Mars -- or why it is so difficult -- or how cool it would be to do so -- you need look no further," said acting NASA Administrator Steve Jurczyk. "Perseverance is just getting started, and already has provided some of the most iconic visuals in space exploration history. It reinforces the remarkable level of engineering and precision that is required to build and fly a vehicle to the Red Planet."

"When NASA's Perseverance rover landed on Mars this week, it also brought the Linux operating system to the Red Planet," reports PC Magazine: The tidbit was mentioned in an interview NASA software engineer Tim Canham gave to IEEE Spectrum. The helicopter-like drone on board the Perseverance rover uses a Linux-powered software framework the space agency open-sourced a few years ago. "This the first time we'll be flying Linux on Mars. We're actually running on a Linux operating system," Canham said.

It also might be the first time NASA has brought a Linux-based device to Mars. "There isn't a previous use of Linux that I'm aware of, definitely on the previous rovers," Canham told PCMag in an email.

Past Mars rovers have used proprietary OSes, largely from the software company Wind River Systems. The same is true for the Perseverance rover itself; the machine has been installed with Wind River's VxWorks, which was used on past Mars missions.
The article also notes that the helicopter-like drone Ingenuity "was built using off-the-shelf parts, including Qualcomm's Snapdragon 801 processor, a smartphone chip."

"Ingenuity is purely a technology demonstration," notes ZDNet. "It's not designed to support the Perseverance mission, which is searching for signs of ancient life and collecting rock and dirt samples for later missions to return to Earth. Its mission is to show that it's possible to fly on Mars using commercial off-the-shelf hardware and open-source software."

NASA's Perseverance rover has successfully touched down on the surface of Mars after surviving a blazing seven-minute plunge through the Martian atmosphere. The rover's clean landing sets the stage for a years-long journey to scour the Red Planet's Jezero Crater for ancient signs of life. From a report: "Touchdown confirmed," Swati Mohan, a member of NASA's entry, descent and landing team, said. "Perseverance is safely on the surface of Mars ready to begin seeking the signs of past life." The landing team of roughly 30 engineers at NASA's Jet Propulsion Laboratory in California jumped from their seats and cheered at the confirmation. Moments after touching down, Perseverance beamed back its first image from one of its 19 cameras. Perseverance hit Mars' atmosphere on time at 3:48PM ET at speeds of about 12,100 miles per hour, diving toward the surface in an infamously challenging sequence engineers call the "seven minutes of terror." With an 11-minute comms delay between Mars and Earth, the spacecraft had to carry out its seven-minute plunge at all by itself with a wickedly complex set of pre-programmed instructions. The moment we learned Perseverance had successfully landed.

It took six and a half months for Perseverance to travel from Cape Canaveral Air Force Station in Florida to the atmosphere of the red planet. It will now take about seven minutes to get from the atmosphere to the sandy ground. The highly-anticipated 293-million-mile journey of Perseverance is moments away from its conclusion. NASA's newest rover is set to touch down in Jerezo Crater at 12:55 p.m. Pacific. If all goes according to plan, Perseverance will begin its search for signs of ancient Martian life after conducting a series of system checks and making other preparations for its mission.

When the Perseverance rover sets down on Mars on Thursday, another NASA spacecraft already there will be listening for the thump-thump that will result when the newcomer arrives. From a report: The hope is that these thumps will create enough shaking to be detected by InSight, a stationary NASA probe that arrived in 2018 to listen for marsquakes with an exquisitely sensitive seismometer. The InSight lander sits more than 2,000 miles to the east of where Perseverance is to land. "We have a reasonable chance of seeing it," said Benjamin Fernando, a graduate student at the University of Oxford in England and a member of the InSight science team. Perseverance will land on Mars at 3:55 p.m. Eastern time on Thursday. NASA Television will provide coverage of the event beginning at 2:15 p.m.

Unless something goes catastrophically wrong, the seismic signals that InSight might hear will not emanate from the rover itself. Perseverance is to be lowered to the surface from a hovering crane, bumping to the ground gently at slower than 2 miles per hour. Rather, scientists will be sifting through InSight's seismic data for signs of the impacts of two 170-pound blocks of tungsten metal that helped keep Perseverance in a stable, balanced spin during its 300-million-mile trip from Earth. At an altitude of 900 miles above Mars, they will be jettisoned as junk, and without parachutes or retrorockets to slow them down, they will then slam into the surface at some 9,000 m.p.h. "This enormous speed means that they'll make quite a substantial crater," Mr. Fernando said. In 2012, similar tungsten blocks from the Curiosity rover, which is almost the same design as Perseverance, left scars visible from orbit.

Microsoft will connect its cloud computing Azure Space platform to the Spaceborne Computer-2, a Hewlett-Packard Enterprise product promising to "deliver edge computing and [artificial intelligence] capabilities to the International Space Station (ISS)." Space.com reports: Spaceborne Computer-2 will launch to space Feb. 20 aboard a Northrop Grumman Cygnus cargo craft that will also deliver tons of other supplies, experiments and food for the station's Expedition 64 astronauts. An Antares rocket will launch the Cygnus NG-15 cargo mission from NASA's Wallops Flight Facility on Wallops Island, Virginia. Spaceborne Computer-2's mission could last two or three years. Once the computer is up and running in orbit, researchers will be able to use the Azure cloud system to do intensive processing or to transmit results back to the device. The computer is based on HPE's Edgeline Converged Edge system designed to operate in harsh environments.

Growing plants in space, modeling dust storms on Earth to assist with Mars mission planning, and doing ultrasound medical imaging for astronaut health care are some of the many fields that the collaboration will address, the companies said in a press release. "The combined advancements of Spaceborne Computer-2 will enable astronauts to eliminate longer latency and wait times associated with sending data to-and-from Earth, to tackle research, and gain insights immediately for a range of projects," the release added.

The new project builds on the lessons learned from a predecessor proof-of-concept device, called Spaceborne Computer. This flew to the space station for a one-year mission in 2017 to investigate computer reliability in space, amid a harsh environment that includes high radiation and zero gravity. "The goal was to test if affordable, commercial off-the-shelf servers used on earth, but equipped with purposefully-designed software-based hardening features, can withstand the shake, rattle and roll of a rocket launch to space, and once there, seamlessly operate on the ISS," the press release said, adding the predecessor mission was a success. "Additionally, gaining more reliable computing on the ISS is just the first step in NASA's goals for supporting human space travel to the moon, Mars and beyond where reliable communications is a mission critical need," the release noted.

For the first time, the ExoMars orbiter detected traces of hydrogen chloride in Mars' atmosphere, presenting Mars scientists with a new mystery to solve: how it got there. ScienceAlert reports: Scientists have been keeping an eye out for gases that contain chlorine in the atmosphere of Mars, since they could confirm that the planet is volcanically active. However, if hydrogen chloride was produced by volcanic activity, it should only spike very regionally, and be accompanied by other volcanic gases. The hydrogen chloride detected by ExoMars did not, and was not. It was sniffed out in both the northern and southern hemispheres of Mars during the dust storm, and the absence of other volcanic gases was glaring.

This suggests that the gas was being produced by some other process; luckily, we have similar processes here on Earth that can help us understand what it could be. It's a several-step process that requires a few key ingredients. First, you need sodium chloride (that's regular salt), left over from evaporative processes. [...] Then there's the Martian polar ice caps which, when warmed during the summer, sublimate. When the resulting water vapor mingles with the salt, the resulting reaction releases chlorine, which then reacts further to form hydrogen chloride. The research has been published in the journal Science Advances.

A Chinese spacecraft went into orbit around Mars on Wednesday on an expedition to land a rover on the surface and scout for signs of ancient life, authorities announced in a landmark step in the country's most ambitious deep-space mission yet. From a report: The arrival of Tianwen-1 after a journey of seven months and nearly 300 million miles (475 million kilometers) is part of an unusual burst of activity at Mars: A spacecraft from the United Arab Emirates swung into orbit around the red planet on Tuesday, and a U.S. rover is set to arrive next week. China's space agency said the five-ton combination orbiter and rover fired its engine to reduce its speed, allowing it to be captured by Mars' gravity. "Entering orbit has been successful ... making it our country's first artificial Mars satellite," the agency announced. The mission is bold even for a space program that has racked up a steady stream of achievements and brought prestige to China's ruling Communist Party.

Launched in July, China's probe "Tianwen-1" is now approaching an orbit around Mars — and it's sent back its first picture. Slashdot reader AmiMoJo spotted this report in the Guardian: The photo released by the China National Space Administration (CNSA) shows geological features including the Schiaparelli crater and the Valles Marineris, a vast stretch of canyons on the Martian surface. The photo was taken from about 1.4m miles away (2.2m kilometres), said the CNSA, with the spacecraft since reaching 1.1 million kilometres from the planet...

The five-tonne Tianwen-1 includes a Mars orbiter, lander, and a rover that will study the planet's soil. China hopes to land the rover in May in Utopia, a massive impact basin...

China has poured billions of dollars into its military-led space programme and first sent a human into space in 2003. It is aiming to assemble a space station in Earth orbit by 2022.

On Tuesday, a test flight of SpaceX's Starship, a huge next-generation spacecraft that Elon Musk, the founder and chief executive of the private rocket company, dreams of one day sending to Mars, came to an explosive end. From a report: That brief flight, to an altitude of about 6 miles and then back to a landing pad, appeared to again demonstrate how the mammoth rocket would tip over on its side as it descended in a controlled belly flop back toward a landing. But when the prototype fired its engines to right itself back to a vertical orientation, it appeared that one engine did not properly ignite, and Starship hit the ground at an angle, disintegrating in a fireball, leaving a cloud of smoke rising over the test site, which is in Boca Chica, Tex., near Brownsville. The end was similar to the last test flight in December which also ended in an explosion at landing, although the particular cause of the rocket failing to slow down enough may have been different.

This time, however, SpaceX at least had the permission of government regulators. Last week, SpaceX and the Federal Aviation Administration, which regulates rocket launches, seemed to be in a strange regulatory standoff. SpaceX had filled the propellant tanks of this prototype of Starship -- its ninth one -- and looked ready to launch. But then the rocket stayed on the ground when no approval from the F.A.A. arrived. Mr. Musk expressed frustration on Twitter, describing the part of the F.A.A. that oversees SpaceX as "fundamentally broken." Mr. Musk wrote, "Their rules are meant for a handful of expendable launches per year from a few government facilities. Under those rules, humanity will never get to Mars." Late on Monday, the F.A.A. gave permission for Tuesday's launch, but then added that the December launch had occurred without the agency's approval. SpaceX had requested a waiver to conduct that flight even though it posed a greater danger to the public than allowed by regulations. The F.A.A. denied the request. SpaceX defied the ruling and launched anyway.

Tesla boss Elon Musk said in an interview late Sunday that a monkey has been wired up to play video games with its mind by a company he founded called Neuralink. CNBC reports: Neuralink put a computer chip into the monkey's skull and used "tiny wires" to connect it to its brain, Musk said. "It's not an unhappy monkey," he said during a talk on Clubhouse, a new social media app gaining popularity that allows people to have informal voice chats while others listen in. "You can't even see where the neural implant was put in, except that he's got a slight like dark mohawk."

The billionaire -- who also spoke about space travel, colonies on Mars, crypto, artificial intelligence and Covid-19 vaccines -- said Neuralink is trying to figure out if it can use its chips to get monkeys to play "mind Pong" with each other. "That would be pretty cool," said Musk, who is CEO of Neuralink, in addition to SpaceX and Tesla. Neuralink's team of around 100 people is trying to develop an implementable computer-brain interface. Musk describes it as a Fitbit in your skull with tiny wires that go into your brain. [...] Musk said Neuralink will "probably" be releasing some videos that show the company's progress in the next month or so. Last August, Neuralink conducted a live demo of its technology on three pigs. A wireless link from the Neuralink device showed the pig's activity activity as it snuffled around a pen on stage.

Musk made the comments on the audio chat app Clubhouse, where he also grilled Robinhood CEO about what happened with GameStop.

The Verge reports that SpaceX's first high-altitude test flight of its Starship rocket, "which launched successfully but exploded in a botched landing attempt in December, violated the terms of its Federal Aviation Administration test license, according to two people familiar with the incident." Both the landing explosion and license violation prompted a formal investigation by the FAA, driving regulators to put extra scrutiny on Elon Musk's hasty Mars rocket test campaign. The so-called mishap investigation was opened that week, focusing not only on the explosive landing but on SpaceX's refusal to stick to the terms of what the FAA authorized, the two people said. It was unclear what part of the test flight violated the FAA license, and an FAA spokesman declined to specify in a statement to The Verge.

"The FAA will continue to work with SpaceX to evaluate additional information provided by the company as part of its application to modify its launch license," FAA spokesman Steve Kulm said Friday. "While we recognize the importance of moving quickly to foster growth and innovation in commercial space, the FAA will not compromise its responsibility to protect public safety. We will approve the modification only after we are satisfied that SpaceX has taken the necessary steps to comply with regulatory requirements."

The heightened scrutiny from regulators after the launchpad spectacle has played a role in holding up SpaceX's latest "SN9" Starship test attempt, which the company said would happen on Thursday. The shiny steel alloy, 16-story-tall rocket was loaded with fuel and ready to fly. But at the time, FAA officials were still going through their license review process for the test because of several changes SpaceX made in its license application, a source said. Musk, frustrated with the process, took to Twitter.
"Unlike its aircraft division, which is fine, the FAA space division has a fundamentally broken regulatory structure," Musk tweeted on Thursday. "Their rules are meant for a handful of expendable launches per year from a few government facilities. Under those rules, humanity will never get to Mars."

The Verge also notes that Musk was asked by the Wall Street Journal what role government should play in regulating innovation just a few hours before Starship's test in December. Musk's reply? "A lot of the time, the best thing the government can do is just get out of the way."

Long-time Slashdot reader schwit1 shared this article from Sky.com: Dr. Fatima Ebrahimi "has invented a new fusion rocket thruster concept which could power humans to Mars and beyond," writes Sky.com

Long-time Slashdot reader schwit1 shared their report: The physicist who works for the U.S. Department of Energy's Princeton Plasma Physics Laboratory designed the rocket which will use magnetic fields to shoot plasma particles — electrically charged gas — into the vacuum of space. According to Newton's second and third laws of motion, the conservation of momentum would mean the rocket was propelled forwards — and at speeds 10 times faster than comparable devices.

While current space-proven plasma propulsion engines use electric fields to propel the particles, the new rocket design would accelerate them using magnetic reconnection... Dr. Ebrahimi's new concept performs much better than existing plasma thrusters in computer simulations — generating exhaust with velocities of hundreds of kilometres per second, 10 times faster than those of other thrusters.

That faster velocity at the beginning of a spacecraft's journey could bring the outer planets within reach of astronauts, the physicist said.... "The next step is building a prototype!"

sciencehabit shares a report from Science Magazine: Researchers have discovered a common martian mineral deep within an ice core from Antarctica. The find suggests the mineral -- a brittle, yellow-brown substance known as jarosite -- was forged the same way on both Earth and Mars: from dust trapped within ancient ice deposits. It also reveals how important these glaciers were on the Red Planet: Not only did they carve valleys, the researchers say, but they also helped create the very stuff Mars is made of.

Jarosite was first spotted on Mars in 2004, when the NASA Opportunity rover rolled over fine-grained layers of it. The discovery made headlines because jarosite needs water to form, along with iron, sulfate, potassium, and acidic conditions. The work suggests jarosite forms the same way on Mars, says Megan Elwood Madden, a geochemist at the University of Oklahoma who was not involved with the research. But she wonders whether the process can explain the huge abundance of jarosite on Mars. "On Mars, this is not just some thin film," she says. "These are meters-thick deposits."

[Giovanni Baccolo, a geologist at the University of Milan-Bicocca] concedes that the ice core contained only small amounts of jarosite, particles smaller than an eyelash or a grain of sand. But he explains that there's much more dust on Mars than in Antarctica, which only receives small amounts of airborne ash and dirt from northern continents. "Mars is such a dusty place -- everything is covered in dust," Baccolo says. More ash would favor more jarosite formation under the right conditions, he says. Baccolo wants to use Antarctic cores to investigate whether ancient martian ice deposits were cauldrons for the formation of other minerals. He says jarosite shows how glaciers weren't just land carving machines, but might have contributed to Mars's chemical makeup. "This is just the first step in linking deep Antarctic ice with the martian environment." The researchers reported their findings this month in Nature Communications.

"NASA declared the Mars digger dead Thursday after failing to burrow deep into the red planet to take its temperature," reports the Associated Press: Scientists in Germany spent two years trying to get their heat probe, dubbed the mole, to drill into the Martian crust. But the 16-inch-long (40-centimeter) device that is part of NASA's InSight lander couldn't gain enough friction in the red dirt. It was supposed to bury 16 feet (5 meters) into Mars, but only drilled down a couple of feet (about a half meter). Following one last unsuccessful attempt to hammer itself down over the weekend with 500 strokes, the team called it quits.

"We've given it everything we've got, but Mars and our heroic mole remain incompatible," said the German Space Agency's Tilman Spohn, the lead scientist for the experiment...

InSight's French seismometer, meanwhile, has recorded nearly 500 Marsquakes, while the lander's weather station is providing daily reports.

"NASA's rocket charged with taking the agency back to the moon fired its four main engines Saturday afternoon, but the test in Mississippi was cut short after a malfunction caused an automatic abort," reports Florida Today...

"We did get an MCF on engine four," a control room member said less than a minute into the test fire, using an initialism that stands for "major component malfunction...." The engines fired for 12 more seconds after the exchange before an automatic shutdown was called. The test was meant to last eight minutes — the full duration needed for the booster during its Artemis program liftoff — but only ran less than two minutes.

Prime contractor Boeing previously said the test would need to run at least 250 seconds, or more than four minutes, for teams to gather enough data to move forward with transport to Kennedy Space Center and launch sometime before the end of the year. An exact plan moving forward, which could mean a second test and delay before transport to Florida, had not yet been released by Saturday evening.
Or, as the Guardian reports, "It was unclear whether Boeing and Nasa would have to repeat the test, a prospect that could push the debut launch into 2022."

In a press conference tonight, a NASA official specifically addressed the question of whether or not a launch this year was still feasible. "I think it's still too early to tell. I think as we figure out what went wrong, we're going to know what the future holds. And right now we just don't know...

"Not everything went according to script today, but we got a lot of great data, a lot of great information. I have absolutely total confidence in the team to figure out what the anomaly was, figure out how to fix it, and then get after it again... Depending on what we learn, we might not have to do it again."

They added that there was no sign of engine damage, and emphasized to reporters another way to view the significance of this afternoon's event. "A rocket capable of taking humans to the moon, was firing, all four engines at the same time." And they also stressed that this afternoon's result was not a failure -- but a test. "When you test, you learn things..."

"We're going to make adjustments, and we're going to fly to the moon. That's what the Artemis program is all about, that's what NASA is all about, and that's what America is all about. We didn't get everything we wanted, and yeah, we're going to have to make adjustments. But this was a test, and this is why we test.

"If you're expecting perfection on a first test, then you've never tested before."

"The date is set," NASA had tweeted Friday, thanking its partners Boeing Space and Aerojet Rocketdyne for Saturday's "hot fire" test of the SLS's core stage.

"One of NASA's main goals for 2021 is to launch Artemis I, an uncrewed moon mission meant to show the Orion spacecraft and Space Launch System rocket can safely send humans to our lunar neighbor," reported CNET. "But first, NASA plans to make some noise with a fiery SLS test on Saturday."

Below is the original report that schwit1 had shared from Space.com: It's a critical test for NASA and the final step in the agency's "Green Run" series of tests to ensure the SLS rocket is ready for its first launch... In the upcoming hot-fire engine test, engineers will load the Boeing-built SLS core booster with over 700,000 gallons of cryogenic (that's really cold) propellant into the rocket's fuel tanks and light all four of its RS-25 engines at once. The engines will fire for 485 seconds (a little over 8 minutes) and generate a whopping 1.6 million pounds of thrust throughout the test...

Following the success of this hot fire test and subsequent uncrewed missions to the moon, "the next key step in returning astronauts to the moon and eventually going on to Mars," Jeff Zotti, the RS-25 program director at Aerojet Rocketdyne said during the news conference. NASA's SLS program manager John Honeycutt agreed.

"This powerful rocket is going to put us in a position to be ready to support the agency in the country's deep space mission to the moon and beyond," he said.

British spacecraft could travel to Mars in half the time it now takes by using nuclear propulsion engines built by Rolls-Royce under a new deal with the UK Space Agency. From a report: The aerospace company hopes nuclear-powered engines could help astronauts make it to Mars in three to four months, twice as fast as the most powerful chemical engines, and unlock deeper space exploration in the decades to come. The partnership between Rolls-Royce and the UK Space Agency will bring together planetary scientists to explore how nuclear energy could be used to "revolutionise space travel," according to the government. Dr Graham Turnock, the chief executive of the UK Space Agency, said using nuclear power in space was "a gamechanging concept that could unlock future deep-space missions that take us to Mars and beyond."

NASA's InSight lander on Mars and the Juno orbiter at Jupiter have new leases on life. From a report: The spacecraft are expected to continue gathering data about their respective planetary targets during their newly extended missions, allowing scientists to learn more about seismic activity on Mars and turn their attention to the moons of Jupiter. Juno's mission has been extended to September 2025 or whenever its life ends with a crash into Jupiter's atmosphere. InSight will continue its mission to study Mars' geology and seismic activity from the Martian surface through December 2022. Both missions are expected to make good use of their extended time at Jupiter and Mars. InSight's extra two years will see the spacecraft collect more data on marsquakes to help create a long-term dataset that scientists can refer to for years to come, according to NASA. Juno will broaden the scope of its studies to observe Jupiter's rings and moons including flybys of Ganymede, Europa and Io.

An anonymous reader writes: The U.S. military's Space Force branch celebrated its one-year anniversary Friday by announcing that its members would now be known as "guardians". But the name was not universally greeted with respect and appreciation. Gizmodo announced the news with a headline which read "Space Force Personnel Will Be Called 'Guardians' Because Sure, Whatever," in an article which jokingly asks how this will affect the other ranks of this branch of the military. "Does someone get promoted from Guardian to Sentinel to Space Paladin to Tython, The Secessionist King Of Mars or something?" (Their article also suggests other names the U.S. military could have considered — like "moon buddies" or "rocketeers" — even at one point proposing "starship troopers".)

Forbes wrote that "The mockery arrived instantly and in great rivers..." But there was an interesting observation from a British newspaper (which is in fact, named The Guardian). "As the Associated Press put it, delicately: 'President-elect Joe Biden has yet to reveal his plans for the space force in the next administration.'" In fact, New York magazine called the new name for members of Space Force the "strongest case yet for its demise," in an article headlined "Abolish the Space Force." ("Maybe 'stormtrooper' was too obvious...")

In an apparent bid to be taken more seriously, on Friday the Space Force also shared an official anniversary greeting they'd received from Lee Majors, the actor who'd played a cybernetically-enhanced Air Force colonel in the 1970s action series The Six Million Dollar Man (who, in later seasons, befriended Bigfoot and the alien community who'd brought him to earth).

But Mashable added sympathetically that "It's been a long year, though. If people want to draw some nerdy joy from a U.S. military branch inadvertently referencing comic books and video games, let them have their fun."
