NASA astronaut Michael Fincke experienced a sudden medical episode aboard the International Space Station (ISS) in January that left him unable to speak and forced him and three other crew members from the ISS. The incident highlighted the need for medical systems during deep-space travel, highlighting the potential risk of such an incident as NASA prepares to send four astronauts around for a 10-day mission under the Artemis program. The medical episode occurred during a dinner at the ISS while the crew was preparing for a spacewalk. The team is now reviewing astronaut medical records to determine if similar incidents have occurred in space.
