NASA ended Crew-11’s stay on the ISS after Mike Fincke suffered an unknown medical event on Jan 7—the first medical evacuation in ISS history—cancelling a spacewalk and returning the crew early on Jan 15; Fincke is recovering at Johnson Space Center, and Crew-12 has since docked to replace them for an eight-month stay.
SpaceX and xAI reportedly plan a million-satellite constellation to run AI data centers in orbit. While proponents cite solar efficiency and lower terrestrial costs, experts warn it could trigger debris cascades (Kessler syndrome), overheating and radiation risks for space hardware, brightening the night sky and harming astronomy, and disruption to Earth observation and climate monitoring; even if feasible, AI training would still require Earth-based resources, and governance gaps could complicate implementation.
