Support teams work Friday around the SpaceX spacecraft shortly after it landed with four astronauts aboard in the Gulf of Mexico off the coast of Pensacola, Fla. A NASA astronaut was taken to the hospital for an undisclosed medical issue after returning from a nearly eight-month stay at the International Space Station extended by Boeing's capsule trouble and Hurricane Milton, the space agency said. Their replacements are Starliner test pilots Butch Wilmore and Suni Williams, whose own mission went from eight days to eight months, and two astronauts launched by SpaceX four weeks ago. Those four will remain in space until February.
