A NASA astronaut who experienced a "medical issue" and was hospitalized after partaking in the successful Space X Crew-8 mission has been released, NASA officials said.

Four astronauts were unexpectedly transferred to a medical facility after their return from space Friday morning.

NASA says an astronaut has been released from the hospital after returning from space. The unidentified NASA astronaut was briefly hospitalized for an unspecified medical issue Friday shortly after returning with three others from a nearly eight-month stay at the International Space Station.
