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. 25. They spent nearly eight months in orbit, longer than expected because of all the trouble with Boeing’s Starliner crew capsule and rough weather, including Hurricane Milton.
