October 25, 2024 at 4:01 PM EST A NASA astronaut aboard SpaceX Dragon was treated for an undisclosed “medical issue” following the rocket’s long-awaited splash landing off the coast of Florida. “After safely splashing down on Earth as part of NASA’s SpaceX Crew-8 mission Friday, a NASA astronaut experienced a medical issue,” NASA said in a press statement. NASA astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps were taken to Ascension Sacred Heart Pensacola in Florida along with Russian cosmonaut Alexander Grebenkin, the space agency said Friday.

NASA didn’t release the name of the astronaut receiving ongoing treatment as a matter of privacy. It doesn’t appear that individual’s health issue was connected with a problematic landing. “During its return to Earth, the SpaceX Dragon executed a normal entry and splashdown,” according to NASA. “Recovery of the crew and the spacecraft was without incident. During routine medical assessments on the recovery ship, the additional evaluation of the crew members was requested out of an abundance of caution.”
