ISS Upgrades 25-Year-Old Laptop Systems to Modern Hardware

The International Space Station is replacing command-and-control systems built around IBM ThinkPad 760 laptops from the 1990s. Astronauts aboard Expedition 74 are swapping out this aging hardware—which ran guidance and multiplexer units—for current technology while keeping research operations running. Worth flagging: the ISS now handles major infrastructure upgrades during active missions. In early station operations, such overhauls would have forced a shutdown of all other work.
