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]

Mobile Servicing System

The Mobile Servicing System is a robotic system onboard the ISS used for assembly and maintenance. During Expedition 40, it was used the replace a broken camera on the system's mobile base with a deteriorated but functional camera from the arm, and to in turn place a new camera on the arm. This marked the first self-repair by a robot in space, and is likely to result in reduced need for time consuming and dangerous space walks. [3]
