Upon achieving orbit approximately nine minutes after launch, Soyuz TMA-13M, delivering the remainder of the crew, began a four-orbit rendezvous with the International Space Station. Soyuz TMA-13M subsequently docked with the Rassvet module of the ISS at 1:44 UTC on May 29. Hatches were opened between the two spacecraft just over two hours later at 3:52 UTC. The expedition ended with the undocking of Soyuz TMA-12M on September 10, 2014. The remainder of Expedition 40's crew joined Expedition 41.[1]
