A NASA astronaut who experienced a "medical issue" following the successful Space X Crew-8 mission has been released from the hospital, NASA officials said Saturday.

       "After an overnight stay at Ascension Sacred Heart Pensacola in Florida, the NASA astronaut was released and returned to NASA’s Johnson Space Center in Houston Saturday. The crew member is in good health and will resume normal post-flight reconditioning with other crew members," NASA said in a statement.

       NASA has not publicly named the astronaut.

       NASA astronauts Matthew Dominick, Michael Barratt and Jeanette Epps and Russian astronaut Alexander Grebenkin were in the SpaceX Dragon capsule when it splashed down on Earth on Friday, NASA said.

       After a medical evaluation, three of the crew members departed from the facility and arrived at NASA's Johnson Space Center in Houston, Texas, NASA said.

       One remaining astronaut remained in the hospital and is in stable condition and is under observation as a precautionary measure, NASA said.

       Recovery of the crew and spacecraft went without incident, according to NASA.

       An additional medical evaluation of the astronauts was requested out of an abundance of caution, NASA said.

       The crew completed a 235-day mission into space.
