For the first time, ESA has established a reserve pool of astronauts. This reserve list is composed of astronaut candidates who were successful throughout the entire selection process but cannot be recruited at this point in time. Astronauts in the reserve remain with their current employers and will receive a consultancy contract and basic support. They will start basic training in case a flight opportunity has been identified.
