ESA astronaut reserve member Sara García Alonso from Spain during a diving training session in ESA's Neutral Buoyancy Facility (NBF) as part of the Astronaut Reserve Training (ART) programme.

In spring 2026, the members of ESA’s astronaut reserve returned to the European Astronaut Centre (EAC) in Cologne, Germany, for the final block of their training. ART prepares members of the European astronaut reserve by providing the broad technical, operational and scientific foundation required to support future human spaceflight opportunities.
