ESA astronauts Matthias Maurer and Thomas Pesquet train for potential missions to the International Space Station at NASA's Johnson Space Center in Houston, Texas, USA. 

Thomas has just been assigned to his second space mission and is expected to be the first European astronaut to fly on a SpaceX Crew Dragon spacecraft in spring 2021. Matthias is training as a backup crew member.

Matthias is also expected to fly his first mission to the Space Station in 2021, but details of this mission are yet to be confirmed.
