While the spacecraft were flying about 250 miles above Eastern Mongolia, an uncrewed Russian Soyuz spacecraft arrived and docked to the International Space Station at 11:08 p.m. EDT.

The Soyuz MS-14 spacecraft attached to the station’s aft-facing Zvezda module for a two-week stay as part of its test flight. The Soyuz delivers 1,450 pounds of cargo, including a Skybot F-850 humanoid robot, to the Expedition 60 crew currently residing on the orbital outpost.

The docking of the unpiloted Soyuz sets the stage for the robotic release of the SpaceX Dragon cargo craft Tuesday morning after a four-week stay at the station. The Dragon is filled with almost 2,700 pounds of valuable scientific experiments and other cargo. NASA Television and the agency’s website will broadcast its departure live beginning at 10:15 a.m. EDT.
