Crew-12 Spy Scandal, AI on Mars & Interstellar Comet's Last Secret?
Four astronauts are stuck in quarantine in Florida as weather keeps pushing back the Crew-12 launch — now targeting no earlier than Friday, February 13. We've got the full story, including the remarkable subplot involving a Russian cosmonaut who was quietly removed from the mission in December. Plus: interstellar comet 3I/ATLAS is on its way out of the solar system forever, but new data from NASA's SPHEREx and James Webb telescopes reveals it's been carrying a chemical cocktail from another star system — one that's unlike anything we've seen in our own comets. Also in today's episode: NASA let an AI drive the Perseverance rover on Mars for two days straight; new research suggests Earth may have hit a rare chemical jackpot during formation that made life possible; the Ring of Fire solar eclipse is just one week away; and Starship is back on track after the Booster 18 disaster, with Flight 12 targeting a March launch window.
