ESA astronauts Thomas Pesquet (left) and Andreas Mogensen in Florida, USA, for a five-day underwater adventure to test tools and practise spacewalks as part of the Seatest mission.
Andreas will live in an underwater habitat with NASA astronauts Joe Acaba and Kate Rubins and Japanese astronaut Soichi Noguchi, while Thomas will stay on shore as flight director and crew communicator.
Inside the Aquarius habitat, the ‘Space Environment Analog for Testing EVA Systems and Training’ – Seatest – mission will be run as if on the International Space Station.
