We lost a true legend this week with the passing of NASA astronaut Jim Lovell at the ripe old age of 97. Lovell commanded the ill-fated Apollo 13 mission back in 1970, and along with crewmates Jack Swigert and Fred Haise — along with just about every person working at or for NASA — he managed to guide the mortally wounded Odyssey command module safely back home. While he’s rightly remembered for the heroics on 13, it was far from his first space rodeo. Lovell already had two Gemini missions under his belt before Apollo came along, including the grueling Gemini 7, where he and Frank Borman undertook the first long-duration space mission, proving that two men stuffed into a Volkswagen-sized cockpit could avoid killing each other for at least two weeks.

AI Is Only Coming For Fun Jobs

July 5, 2025 by 39 Comments

In the past few years, what marketers and venture capital firms term “artificial intelligence” but is more often an advanced predictive text model of some sort has started taking people’s jobs and threatening others. But not tedious jobs that society might like to have automated away in the first place. These AI tools have generally been taking rewarding or enjoyable jobs like artist, author, filmmaker, programmer, and composer. This project from a research team might soon be able to add astronaut to that list.

The team was working within the confines of the Kerbal Space Program Differential Game Challenge, an open-source plugin from MIT that allows developers to test various algorithms and artificial intelligences in simulated spacecraft situations. Generally, purpose-built models are used here with many rounds of refinement and testing, but since this process can be time consuming and costly the researchers on this team decided to hand over control to ChatGPT with only limited instructions. A translation layer built by the researchers allows generated text to be converted to spacecraft controls.

We’ll note that, at least as of right now, large language models haven’t taken the jobs of any actual astronauts yet. The game challenge is generally meant for non-manned spacecraft like orbital satellites which often need to make their own decisions to maintain orbits and avoid obstacles. This specific model was able to place second in a recent competition as well, although we’ll keep rooting for humans in certain situations like these.

So far, food for astronauts hasn’t exactly been haute cuisine. Freeze-dried cereal cubes, squeezable tubes filled with what amounts to baby food, and meals reconstituted with water from a fuel cell don’t seem like meals to write home about. And from the sound of research into turning asteroids into astronaut food, things aren’t going to get better with space food anytime soon. The work comes from Western University in Canada and proposes that carbonaceous asteroids like the recently explored Bennu be converted into edible biomass by bacteria. The exact bugs go unmentioned, but when fed simulated asteroid bits are said to produce a material similar in texture and appearance to a “caramel milkshake.” Having grown hundreds of liters of bacterial cultures in the lab, we agree that liquid cultures spun down in a centrifuge look tasty, but if the smell is any indication, the taste probably won’t live up to expectations. Still, when a 500-meter-wide chunk of asteroid can produce enough nutritionally complete food to sustain between 600 and 17,000 astronauts for a year without having to ship it up the gravity well, concessions will likely be made. We expect that this won’t apply to the nascent space tourism industry, which for the foreseeable future will probably build its customer base on deep-pocketed thrill-seekers, a group that’s not known for its ability to compromise on creature comforts.

Remember that time a giant cylindrical aquarium in a Berlin hotel bar catastrophically failed and left thousands of fish homeless? We sure do, and further recall that at the time, we were very curious about the engineering details of how this structure failed so spectacularly. At the time, we were sure there’d be plenty of follow-up on that score, but life happened and we forgot all about the story. Luckily, a faithful reader named Craig didn’t, and he helpfully ran down a few follow-up articles that came out last year that are worth looking at.

The first is from prosecutors in Berlin with a report offering three possibilities: that the adhesive holding together the acrylic panels of the aquarium failed; that the base of the tank was dented during recent refurbishment; or that the aquarium was refilled too soon after the repairs, leading to the acrylic panels drying out. We’re a little confused by that last one just from an intuitive standpoint, but each of these possibilities seems hand-wavy enough that the report’s executive summary could have been “Meh, Scheiße happens.”

Another day, another crop of newly minted minimal astronauts, as Blue Origin’s New Shepard made a successful suborbital flight this week. Everything seemed to go according to plan, at least until right at the end, when an “unexpected foliage contingency” made astronaut egress a little more complicated than usual. The New Shepard capsule had the bad taste to touch down with a bit of West Texas shrubbery directly aligned with the hatch, making it difficult to find good footing for the platform used by the astronauts for the obligatory “smile and wave” upon exiting. The Blue Origin ground crew, clad in their stylish black and blue outfits that must be murderously impractical in the West Texas desert, stamped down the brush to place the stairway, but had a lot of trouble getting it to sit straight. Even with the impromptu landscaping, the terrain made it tough to get good footing without adding random bits of stuff to prop up one leg, an important task considering that one of the new astronauts was a 90-year-old man. It seems pretty short-sighted not to have adjustable legs on the stairway, but there it is.

Alone, But Not Lonely: Remembering Astronaut Michael Collins

April 28, 2021 by 21 Comments

With many of the achievements of the Space Race now more than half a century behind us, it’s no wonder that we’re steadily losing the men who rode the rockets of the Mercury, Gemini, and Apollo programs into space. They were all very much in their primes at the time, but no matter what you’ve accomplished in life, even if it includes a trip to the Moon, time eventually catches up to you.

Still, it was quite a shock to learn today that astronaut Michael Collins passed away today at the age of 90. Collins made his trip to the Moon aboard Apollo 11, the mission which would see his crewmates Neil Armstrong and Edwin “Buzz” Aldrin descend to the surface in the Lunar Module Eagle and take the historic first steps on its surface in July of 1969.

An Out-Of-This-World Opportunity; Become An ESA Astronaut

February 9, 2021 by 25 Comments

In the six decades or so of human space exploration, depending on whose definition you take, only 562 people have flown in to space. We haven’t quite reached the state of holidaying in space that science fiction once promised us even though the prospect of sub-orbital spaceflight for the exceedingly well-heeled is very close, so that cadre of astronauts remains an elite group whose entry is not for the average person. Some readers might have an opportunity to change that though, as the European Space Agency have announced a fresh round of astronaut recruitment that will open at the end of March.

Sadly for our American readers the successful applicants have to hail from ESA member states, but since that covers a swathe of European countries we’re guessing that a lot of you might have your long-held dreams of spaceflight revived by it. You can learn more at a press conference to be held on the 16th of February, and streamed via ESA Web TV. Meanwhile whoever is recruited will be likely not only to participate in missions to the ISS, but maybe also more ambitious planned missions such as those to the planned Lunar Gateway space station in Lunar orbit. If you think you’ve got the Euro version of The Right Stuff, you’ll have the 8 weeks from the end of March until the 28th of May to get your application in. Good Luck!
