Soyuz MS-09 undocking, landing


Russian cosmonaut Sergey Prokopyev, European Space Agency astronaut Alexander Gerst and NASA astronaut Serena Aunon-Chancellor are set to return to Earth in their Soyuz MS-09 spacecraft on Dec. 20, 2018.

The trio was original supposed to land Dec. 13, 2018, but because of the Oct. 11, 2018, Soyuz MS-10 launch abort, this date of the crew’s return was postponed by about a week. Additionally, the Soyuz MS-11 crew launch was moved forward to Dec. 3.

Undocking of Soyuz MS-09 is currently anticipated for 1:42 UTC with a deorbit burn at 4:09 and landing in Kazakhstan at 5:03. Once the trio departs the space station, Expedition 57 will officially conclude and Expedition 58 will start.
