On March 27, 2014 at 23:53 UTC the "Soyuz TMA-12M” spacecraft docked with the Russian "Poisk” (MIM-2) module of the International Space Station in automatic regime. The docking, originally scheduled for March 26, was postponed due to an orientation problem. The Soyuz TMA-12M delivered three new members of Expedition 39 to the ISS, Russian cosmonaut Aleksandr Skvortsov and Oleg Artemyev as well as American astronaut Steven Swanson.

The hatches between the "Soyuz TMA-12M” and the space station were opened at 02:34 UTC on March 28, 2014. The new comers joined current ISS expedition members – Russian cosmonaut Mikhail Tyurin, American astronaut Richard Mastracchio and Japanese astronaut Koichi Wakata to form Expedition 39 crew of 6 members. The six crew members will be working together aboard the orbital station until May.
