ESA astronaut Andreas Mogensen woke up at 1:20 local time at night, eight hours before launch. He passed his last medical procedures and final medical check and received an official call for medical flight readiness.

A new bus took commander Sergei Volkov, Andreas and Aidyn Aimbetov at 05:00 local time to the Baikonur cosmodrome, building 254 to don their Sokol spacesuits they will wear in the Soyuz spacecraft during launch.
