NASA wants volunteers for its second year-long simulated Mars mission, the Crew Health and Performance Exploration Analog (CHAPEA 2). For the mission’s duration, starting spring 2025, the four selected crew members will live in a 1,700-square-foot 3D-printed habitat in Houston. It’s paid, but we don’t know how much. At least living costs will be nil.

The Mars Dune Alpha habitat at NASA’s Johnson Space Center simulates life for future explorers on the red planet, where the environment is harsh and resources limited.

Applicants must be US citizens aged 30 to 55, speak English proficiently and have a master’s degree in a STEM field, plus at least two years of professional experience, a minimum of one thousand hours piloting an aircraft. Or two years of work toward a STEM doctoral program.

I barely qualify for two of those requirements — good luck to the rest of you.

The EU is reportedly hitting Apple with a $539 million fine in antitrust probe

It’s been investigating Apple’s App Store rules since a 2019 complaint from Spotify.

Apple may be facing a fine of roughly $539 million (€500 million) from the EU and a ban on its alleged anti-competitive App Store practices for music streaming services, according to The Financial Times. The publication cites five unnamed sources and says the European Commission will announce its ruling early next month.

The investigation was prompted by a 2019 antitrust complaint filed by Spotify and focuses on App Store rules that, at the time, prevented developers from directing customers to alternative subscriptions outside the app, which could be notably cheaper as they didn’t have to include Apple’s 30 percent fee.

Your dank memes, confessional posts and excessively strong feelings on Baldur’s Gate 3 couplings will soon train an artificial intelligence company’s models, according to Bloomberg. The website reportedly signed a deal “worth about $60 million on an annual basis” earlier this year.

When Reddit started charging companies for API access in April 2023, it said pricing would split in tiers so even smaller clientele could afford to pay. Companies need that API access to train their chatbots on posts and comments. This is likely the top tier of all that.

Intuitive Machines’ moon lander sent home its first images

The landing attempt is scheduled for February 22.

Intuitive Machines

Intuitive Machines’ own attempt at the first-ever commercial Moon landing is off to a good start. After launching without a hitch on Thursday, it snapped a few incredible images of Earth. The team posted a series of updates on X at the end of the week, confirming the lander has passed some key milestones, including engine firing, ahead of its touchdown.

Astroscale’s ADRAS-J spacecraft, a demonstration satellite that could inform future space junk cleanup efforts, is now in orbit after a successful launch from New Zealand on Sunday. The satellite was sent to space atop an Electron rocket from Rocket Lab. Its mission, which was selected by Japan’s space agency (JAXA) for Phase I of the Commercial Removal of Debris Demonstration program, will see ADRAS-J rendezvous with an old Japanese rocket upper stage that’s been in orbit since 2009.

The accumulation of waste in Earth’s orbit from decades of spaceflight is an issue of growing concern, and space agencies around the world are increasingly working to address it, in many cases tapping private companies to develop potential solutions. One of the most effective ways to deal with space junk could be to deorbit it, or move it to a lower altitude so it can burn up in Earth’s atmosphere. ADRAS-J will be the first to target a piece of existing large debris and attempt to safely approach and characterize it, relying on ground-based data to hone in on its position.

Over the next few months, it’ll make its way to the target and eventually try to get close enough to take images and assess its condition to determine if it can be removed. “ADRAS-J is officially on duty and ready to rendezvous with some space debris!” the company tweeted. “Let the new era of space sustainability begin!”

Intuitive Machines’ lunar lander is well on its way to the moon after launching without a hitch on Thursday, but it managed to snap a few incredible images of Earth while it was still close to home. The company shared the first batch of images from the IM-1 mission on X today after confirming in an earlier post that the spacecraft is “in excellent health.” Along with a view of Earth and some partial selfies of the Nova-C lander, nicknamed Odysseus, you can even see the SpaceX Falcon 9 second stage falling away in the distance after separation.

Odysseus is on track to make its moon landing attempt on February 22, and so far appears to be performing well. The team posted a series of updates on X at the end of the week confirming the lander has passed some key milestones ahead of its touchdown, including engine firing. This marked “the first-ever in-space ignition of a liquid methane and liquid oxygen engine,” according to Intuitive Machines.

If extreme challenges are your cup of tea, NASA has the perfect opportunity for you. The space agency put out a call on Friday for volunteers to participate in its second yearlong simulated Mars mission, the Crew Health and Performance Exploration Analog (CHAPEA 2). For the duration of the mission, which will start in spring 2025, the four selected crew members will be housed in a 1,700-square-foot 3D-printed habitat in Houston. NASA is accepting applications on the CHAPEA website from now through April 2. It’s a paid gig, but NASA hasn’t publicly said how much participants will be compensated.

The Mars Dune Alpha habitat at NASA’s Johnson Space Center is designed to simulate what life might be like for future explorers on the red planet, where the environment is harsh and resources will be limited. There’s a crew currently living and working there as part of the first CHAPEA mission, which is now more than halfway through its 378-day assignment. During their stay, volunteers will perform habitat maintenance and grow crops, among other tasks. The habitat also has a 1,200-square-foot sandbox attached to it for simulated spacewalks.

To be considered, applicants must be a US citizen aged 30-55, speak English proficiently and have a master’s degree in a STEM field, plus at least two years of professional experience, a minimum of one thousand hours piloting an aircraft or two years of work toward a STEM doctoral program. Certain types of professional experience may allow applicants without a master’s to qualify too. CHAPEA 2 is the second of three mission NASA has planned for the program, the first of which began on June 25, 2023. 

Intuitive Machines' Odysseus has started making its way to the moon and could make history as the first privately built lander to touch down on the lunar surface. The lander was ferried to space by a SpaceX Falcon 9 rocket using a booster that already had 17 flights under its belt before this one and could even fly again in the future, seeing as it had safely returned to Earth on the company's Landing Zone 1. Both SpaceX and Intuitive Machines have confirmed that Odysseus has successfully been deployed and has started its multi-day journey to the moon. 

To be exact, Intuitive Machines has set its sights on the Malapert A crater near the moon's south pole as Odysseus' landing site. The spacecraft can operate for around 14 Earth days when powered by sunlight, but the company is hoping for touchdown to take place by February 22. Odysseus, the first of the Nova-C type landers Intuitive Machines is planning to launch this year, is carrying five NASA payloads in addition to commercial cargo. 

The mission's objectives include demonstrating precision landing and testing certain communication and navigation node capabilities. It will also observe how rocket plumes and space weather interact with the lunar surface. IM-1 was one of the missions NASA had chosen to take its scientific instruments to the moon over the next few years as part of its Commercial Lunar Payload Services (CLPS) initiative. The first of the CLPS missions to take off was Astrobotic's Peregrine Mission 1, which unfortunately experienced an anomaly that prevented the lander from pointing its solar panels at the sun and caused it to leak propellant. Peregrine never made it to the moon and ended its journey by burning up in the Earth's atmosphere upon reentry. 

Since 1979, Arctic ice has shrunk by 1.35 million square miles, a new JPL study found ice loss in Greenland is far worse than previously thought and Antarctic ice is now at the lowest level since records began. The more they melt, the faster the rate of decline for the ice that remains until we’re faced with a series of catastrophes. The most immediate of which is sea level rise which threatens to eradicate whole nations that are situated on low-lying islands. How do we stop such a problem? While we remedy the longer-term issues around fossil fuel consumption, we might have to buy ourselves more time with geoengineering.

The severity of this situation can’t be stressed enough. Professor John Moore of the Arctic Center, University of Lapland, says that we’re long past the point where emissions reductions alone will be effective. “We are faced with this situation where there’s no pathway to 1.5 [degrees] available through mitigation,” he said. “Things like the ice sheets [melting] and other tipping points will happen regardless,” adding that the Earth’s present situation is akin to a patient bleeding out on the operating table, “we are in this situation where we cannot mitigate ourselves out of the shit.”

Moore is one of the figures behind Frozen Arctic, a report produced by the universities of the Arctic and Lapland alongside UN-backed thinktank GRID-Arendal. It’s a rundown of sixty geoengineering projects that could slow down or reverse polar melting. A team of researchers opted to examine every idea, from those already in place to the ones at the fringes of science. “We wanted to be thorough,” said Moore, “because even the craziest idea might have a nugget of gold in there.” Each approach has been given a brief analysis, examining if it’s feasible on a scientific or practical basis, if it would be potentially helpful and how much it would cost. The report even went so far as to look at pykrete, a wacky World War Two initiative to create artificial glaciers for strategic use by mixing sawdust or paper products into ice.

If you’re curious and don’t have a day or two to read the report yourself, you can boil down the approaches to a handful of categories. The first is Solar Radiation Management, i.e. making the polar regions more reflective to bounce away more of the sun’s heat. Second, there’s artificial ice generation to compensate for what has already been lost. Third, enormous engineering work to buttress, isolate and protect the remaining ice — like massive undersea walls that act as a barrier against the seas as they get warmer. Finally, there are measures that nibble at the edges of the problem in terms of effect, but have more viable long-term success, like preventing flora and fauna (and the warmth they radiate) from encroaching on regions meant to remain frozen.

If you’re a climate scientist, the likely most obvious approach is the first, because we’ve seen the positive effects of it before. Albedo is the climate science term to describe how white ice acts as an enormous reflector, bouncing away a lot of the sun’s heat. Ice ages dramatically increase albedo, but there are more recent examples in living memory: In 1991 Mount Pinatubo, a volcano in the Philippines, erupted, spewing an enormous amount of volcanic ash into the atmosphere. (The event also caused a large amount of damage, displaced 200,000 people and claimed the lives of at least 722.) According to NOAA, the ash dumped into the atmosphere helped reflect a lot of solar heat away from the Earth, causing a temporary global cooling effect of roughly 1.5 degrees celsius. The devastation of Pinatubo isn’t desirable, nor was the ozone depletion that it caused, but that cooling effect could be vital to slowing global warming and polar melting.

It’s possible to do this artificially by seeding the clouds with chemicals deposited by an airplane or with ground-based smoke generators, which can also be used to promote rain clouds. This is a tactic already used in China to help make rain for agriculture and to alleviate drought-like conditions. In this context, the clouds would act as a barrier between the sun and the ice caps, bouncing more of that solar radiation away from the Earth’s surface. Unfortunately, there’s a problem with this approach, which is that it’s incredibly expensive and incredibly fussy. The report says it’s only viable when the right clouds are overhead, and the work would require enormous infrastructure to be built nearby. Not to mention that while we have some small shreds of evidence to suggest it might be useful, there’s nothing proven as yet.

And then there are the second order effects when these approaches then spill over into the rest of the global ecosystem. “If you do sunlight reflection methods and you put anything up in the atmosphere, it doesn’t stay where you put it.” That’s the big issue identified by Dr. Phil Williamson, honorary associate professor at the University of East Anglia and a former contributor to the UN’s keystone Intergovernmental Panel on Climate Change reports. His concern is that regional, targeted climate solutions “don’t solve the problem for the whole world,” and that if you’re not tackling climate change on a global scale, then you’re “just accentuating the difference.” With a cold arctic, but rising temperatures elsewhere, you’re climbing aboard a “climate rollercoaster.”

Second in the ranking of hail-mary climate approaches is to build a freezer to both cool down the existing ice and make more. Sadly, many ideas in this area forget that ice sheets are not just big blocks of immovable ice and are, in fact, liable to move. Take the idea of drilling down two miles or so into the ice sheet and pumping out the warm water to cool it down: Thanks to the constantly shifting ice and water, a new site would need to be drilled fairly regularly.

There’s another problem: The report says one project to bore a hole down 2.5km (1.5 miles) burned 450,000 liters of fuel. Not to mention how much energy it would consume to run the heat exchangers or freezers to create fresh ice on such a scale. That's a considerable amount of greenhouse gas pollution for a project meant to undo that exact type of damage. Dumping a layer of artificially-made snow on a mountain may work fine for a ski resort when the powder’s a little thin, but not the whole planet.

As hard as the scientific and engineering battles will be, there’s also the political one that will need addressing. “A lot of people get quasi-religiously upset about putting stuff into the stratosphere,” said Professor John Moore, “you’d think they’d get similarly upset about greenhouse gasses.” One strategy under consideration is to inject sulfur into the atmosphere to replicate the cooling effects observed after major volcanic eruptions. The sulfur would form SO2, creating thick layers of dense cloud to block more heat from reaching the ice. But if you, like me, have a high school-level knowledge of science, that’s a scary prospect given that sulfur dioxide would resolve to sulfuric acid. Given the microscopic quantities involved, there would be little-to-no impact on the natural world. But the image of acid rain pouring down from the clouds means it’d be a hard sell to an uninformed population.

But if there is a reason for concern, it’s that any unintended consequences could pose a problem in the global political space. “It’s almost like declaring war on the rest of the world if [a nation] goes it alone,” says Phil Williamson, “because any damage or alteration to the global climate system, the country that did it is responsible for all future climatic disasters because the weather isn’t the same.”

Of course, Moore knows that the Frozen Arctic report’s conclusions aren’t too optimistic about a quick fix. He feels its conclusions should serve as a wake-up call for the planet. “Nobody is going to scale up something for the entire arctic ocean overnight,” he said, but that this is the time to “find ideas that might be valuable [...] and then put resources into finding out if [those ideas] really are useful.” He added that the short turnaround time before a total climate disaster isn’t much of an issue, saying “engineers can pretty much do anything you ask them to if you put enough resources into it.” Because the alternative is to do nothing, and “every day that we choose to do nothing, we accept more of the damages that are coming.”

Houston-based space company Intuitive Machines is gearing up for an actual moonshot at the end of this month, when it’ll try to land a spacecraft named Odysseus on the lunar surface — ideally without it breaking in the process. The mission follows Astrobotic’s unsuccessful attempt in January; that company’s lander, Peregrine, never made it to the moon due to a propellant leak that cut its journey short. Peregrine’s failure means Intuitive Machines’ IM-1 mission could be the first ever commercial moon landing if it makes it there intact.

Intuitive Machines is hoping to make its landing attempt on February 22, targeting the Malapert A crater near the moon’s south pole for touchdown. This arrival date is dependent on Odysseus, one of the company’s Nova-C class landers, leaving Earth atop a SpaceX Falcon 9 rocket sometime between February 14 and February 16. The launch window opens at 12:57AM ET on Wednesday.

Odysseus is the first of three Nova-C landers Intuitive Machines plans to send to the moon this year, all of which will have commercial payloads on board and NASA instruments as contracted under the agency’s Commercial Lunar Payload Services (CLPS) program. At 14 feet tall (4.3 meters), the lander is roughly the size of a giraffe and can carry about 280 pounds (130kg) of cargo. Its mission, if it nails a soft landing, will be a short but potentially valuable one for informing future excursions to the region, including NASA’s upcoming crewed Artemis missions. Orbiting probes have found evidence of water ice at the lunar south pole, which could be used for astronaut subsistence and even fuel, making it an area of high interest for human exploration.

NASA

The solar-powered craft and any functional equipment it’s carrying are only expected to be in working condition for about a week before the onset of lunar night, a 14-day period of frigid darkness that the company says will leave the lander inoperable. But while everything’s up and running, the various instruments will gather data at the surface. NASA awarded Intuitive Machines a $77 million contract for the delivery of its payloads back in 2019, and there are six NASA instruments now hitching a ride on Odysseus.

One, the Laser Retroreflector Array (LRA), will “function as a permanent location mark” from its position on the moon after landing to help incoming spacecraft determine their distance from the surface, according to NASA. The lander is also carrying the Navigation Doppler LIDAR for Precise Velocity and Range Sensing (NDL), a sensor that measures velocity and altitude to better guide the descent, and the Lunar Node 1 Navigation Demonstrator (LN-1) to support communication and autonomous navigation in future missions.

NASA is also sending instruments to study surface plumes — everything that gets kicked up when the lander touches down — along with radio waves and the effects of space weather. That includes the Stereo Cameras for Lunar Plume-Surface Studies (SCALPSS), which will capture images of these dust plumes, and the Radio wave Observation at the Lunar Surface of the photoElectron Sheath (ROLSES) instrument.

The rest of the payloads on board Odysseus are commercial. Columbia Sportswear worked with Intuitive Machines to incorporate the brand’s Apollo-inspired Omni-Heat Infinity thermal reflective material, which is being used for this mission to help protect the cryogenic propulsion tank, according to Intuitive Machines. Students at Embry-Riddle Aeronautical University developed a camera system dubbed the EagleCam that will attempt to separate from the lander before it touches down and snap a picture of the moment from a third-person point of view. EagleCam is also equipped with an experimental dust-removal system.

There are even some Jeff Koons sculptures heading to the moon, which will have physical and NFT counterparts back on Earth. In Koons’ Moon Phase piece, 125 small stainless steel sculptures of the moon at different phases are encased in a clear cube made by 4Space, with the names of important historical figures from around the world listed below each sphere. The International Lunar Observatory Association, based in Hawaii, and Canadensys Aerospace are sending a 1.3-pound dual-camera system called ILO-X, with which they’ll attempt to capture wide and narrow field images of the Milky Way from the moon.

Odysseus is also carrying small discs called “Lunagrams” from Galactic Legacy Labs that contain messages from Earth, including text, images, audio and archives from major databases such as the Arch Mission Foundation and the English-language version of Wikipedia. Similar archival materials were sent to space with Peregrine last month. The information technology company Lonestar plans to demonstrate its Disaster Recovery as a Service (DRaaS) by storing data on the lander and transmitting documents ( including the US Declaration of Independence) between Earth and the moon. It’ll follow this up with a prototype mini data center on Intuitive Machines’ next launch.

Now, the pressure is on for the Odysseus Nova-C lander to actually get to the lunar surface safely. This year started off rocky for moon missions, with the failure of Astrobotic’s Peregrine and a descent hiccup that caused JAXA’s SLIM spacecraft to faceplant into the lunar surface (though the latter was miraculously able to resume functions to some degree after a few days). Intuitive Machines will have other chances to get it right if it doesn’t this time — it has multiple missions already booked up — but only one private lander can be “first.”

Even NASA is not immune to layoffs. The agency says it's cutting around 530 employees from its Jet Propulsion Laboratory (JPL) in California amid budget uncertainty. That's eight percent of the facility's workforce. JPL is laying off about 40 contractors too, just weeks after imposing a hiring freeze and canning 100 other contractors. Workers are being informed of their fates today.

"After exhausting all other measures to adjust to a lower budget from NASA, and in the absence of an FY24 appropriation from Congress, we have had to make the difficult decision to reduce the JPL workforce through layoffs," NASA said in a statement spotted by Gizmodo. "The impacts will occur across both technical and support areas of the Lab. These are painful but necessary adjustments that will enable us to adhere to our budget allocation while continuing our important work for NASA and our nation."

Uncertainty over the final budget that Congress will allocate to NASA for 2024 has played a major factor in the cuts. It's expected that the agency will receive around $300 million for Mars Sample Return (MSR), an ambitious mission in which NASA plans to launch a lander and orbiter to the red planet in 2028 and bring back soil. In its 2024 budget proposal, NASA requested just under $950 million for the project.

“While we still do not have an FY24 appropriation or the final word from Congress on our Mars Sample Return (MSR) budget allocation, we are now in a position where we must take further significant action to reduce our spending,” JPL Director Laurie Leshin wrote in a memo. "In the absence of an appropriation, and as much as we wish we didn’t need to take this action, we must now move forward to protect against even deeper cuts later were we to wait."

NASA has yet to provide a full cost estimate for MSR, though an independent report pegged the price at between $8 billion and $11 billion. In its proposed 2024 budget, the Senate Appropriations subcommittee ordered NASA to submit a year-by-year funding plan for MSR. If the agency does not do so, the subcommittee warned that the mission could be canceled.

That's despite MSR having enjoyed success so far. The Perseverance rover has dug up some soil samples that contain evidence of organic matter and would warrant closer analysis were NASA able to bring them back to Earth. The samples could help scientists learn more about Mars, such as whether the planet ever hosted life.

Against all odds, Japan’s SLIM lander managed to turn back on more than a week after it plopped upside down onto the surface of the moon — but now, it’s gone dormant for the duration of the lunar night, and it may not be able to wake up again. The SLIM team from the Japanese space agency, JAXA, on Thursday shared the last image the lander captured at the moon’s Shioli crater before dusk, as night encroached. Lunar night lasts the equivalent of two Earth weeks and can get colder than 200 degrees Fahrenheit.

The team has confirmed that the solar powered lander is in a dormant state that will last at least the duration of the lunar night. Its chances of resuming operations afterward aren’t great, but then again, it’s already surprised us once. “Although SLIM was not designed for the harsh lunar nights, we plan to try to operate again from mid-February, when the Sun will shine again on SLIM’s solar cells,” the team wrote on X. If this truly is SLIM’s last photo, it sure is a spooky one.

The first metal 3D printer that will be used in space is on its way to the International Space Station. The Cygnus NG-20 supply mission, which is carrying the 180kg (397 lbs) printer, launched on Tuesday and is set to arrive at the ISS on Thursday.

Astronaut Andreas Mogensen will install the printer, which Airbus developed for the European Space Agency. The machine will then be controlled and monitored from Earth.

Polymer-based 3D printers have been employed on the ISS in the past, but metal 3D printing in orbit is said to pose a trickier challenge. The machine will use a form of stainless steel that’s often used for water treatment and medical implants because of how well it resists corrosion.

After the stainless steel wire is pushed into the printing area, the printer melts it with a laser said to be a million times more powerful than a typical laser pointer. The printer then adds the melted metal to the print.

The melting point of the metal is around 1,400°C and the printer will run inside a completely sealed box. Before the printer can operate, it needs to vent its oxygen into space and replace its atmosphere with nitrogen. Otherwise, the melted metal would oxidize when it became exposed to oxygen.

Given the higher temperatures that are employed compared with a plastic 3D printer (which heats to around 200°C), "the safety of the crew and the Station itself have to be ensured — while maintenance possibilities are also very limited," ESA technical officer Rob Postema told the agency's website. "If successful though, the strength, conductivity and rigidity of metal would take the potential of in-space 3D printing to new heights.”

Four test prints are scheduled. The printer will replicate reference prints that have been created back on Earth. The two versions will be compared to help scientists understand how printing quality and performance differs in space. Even though each print will weigh less than 250g (8.8 ounces) and be smaller than a soda can, it will take the printer between two and four weeks to create each one. The printer will only be in operation for a maximum of four hours each day, since its fans and motor are fairly loud and the ISS has noise regulations.

If the experiment goes well, it will pave the way for astronauts and space agencies to print required tools or parts without having to send the items on resupply missions. Metal 3D printing could also help with the construction of a lunar base using recycled materials or transformed regolith (moon soil and rock). It may come in useful for missions to Mars too.
