ESA astronaut Andreas Mogensen, commander Sergei Volkov and Aidyn Aimbetov were launched into space on 2 September at 04:38 GMT (06:38 CEST) from Baikonur cosmodrome, Kazakhstan.
The launch marks the start of ESA’s 10-day ‘iriss’ mission that will focus on testing new technologies and ways of running complex space missions.
The astronaut’s Soyuz TMA-18M spacecraft was pushed into Earth orbit as planned accelerating 50 km/h on every second for the first nine minutes of their launch.
Their docking is planned on 4 September at 07:42 GMT (09:42 CEST) but they will not enter their new home in space until the astronauts on both sides of the spacecraft hatch to ensure that there are no leaks.
