[2] Randall applied to the 2008/2009 astronaut selection of the European Space Agency (ESA), but failed the initial psychological tests.

Die Astronautin initially planned to send an astronaut to stay around ten days on the International Space Station by 2019, at the latest,[8] but this was later postponed to 2023.
