Three NASA astronauts whose prolonged space station mission ended with a trip to the hospital last month declined to say Friday which one of them was sick. Astronauts Matthew Dominick, Michael Barratt and Jeanette Epps publicly discussed their spaceflight for the first time since returning from the International Space Station on Oct.

NASA is not yet providing details about what caused a SpaceX Crew-8 astronaut to be hospitalized late last month, citing medical privacy concerns.
