NASA's Johnson Space Center (JSC) in Houston, Texas
Following the foundational instruction phase conducted at the European Astronaut Centre (EAC) in Cologne, ESA astronauts move to the primary training centers managed by partner agencies for mission-specific preparation. The most notable of these secondary locations is NASA's Johnson Space Center (JSC), situated in Houston, Texas. It is at JSC where astronauts undergo intensive training focused specifically on the entirety of the ISS, which includes achieving mastery over critical operational areas such as the station's robotics systems, life support mechanisms, and essential emergency response protocols.
