According to the original plan, ISS will be adjusted its trajectory on December 13, but the US has offered to postpone it shortly before the process begins.

In addition to preparing the Soyuz train, this trajectory adjustment also aims to test a new algorithm to prevent ISS from colliding with space junk.

The Soyuz TMA-07M is expected to be launched from Baikonur Space Center on December 19, carrying three astronauts Roman Romanenko (Russia), Chris Hadfield (Canada) and Tomas Marshburn (USA).

It is expected that the ship will connect with ISS on December 21, then return to Earth, the three above astronauts will stay in ISS for 5 months to carry out research missions on the universe.
