The prime and backup crewmembers of manned transport spacecraft Soyuz MS-09 proceeded with their final training at Baikonur Cosmodrome, including skill training in their places onboard the spacecraft.

Earlier a Technical Management meeting was held, where a decision was taken to fuel Soyuz MS-09 with propellant components and compressed gases.
