On March 19, 2017 at 14:46 UTC the "Dragon” capsule splashed down in the Pacific Ocean at about 320 km southwest from Long Beach, California, USA. The Dragon delivered to Earth 1652 kilograms of cargo. It was the "SpaceX CRS-10” mission. CRS means Commercial Resupply Services. It was the 10th flight of Dragon to the ISS with docking.

On March 18, 2017 at 21:20 UTC the station's robotic arm removed the “Dragon” SpX-10 (CRS-10 flight) unmanned supply spacecraft from a berthing port on the Harmony module of the International Space Station. The spacecraft was moved to a stow position below the station where it stayed overnight. On March 19, controlled by ground controllers and then American astronaut Robert Kimbrough and French astronaut Thomas Pesquet, the robotic arm let go of the "Dragon” resupply vehicle at 09:11 UTC.

On March 19, 2017 at 00:18 UTC the “Delta-4M” rocket-carrier was launched from Cape Canaveral launch site of US Air Force. The launch was performed by United Launch Alliance supported by the 45th Space Wing of US Air Force. The rocket orbited the WGS-9 (Wideband Global Satcom 9) military communications satellite. This new satellite is unique because Canada, Denmark, the Netherlands, Luxembourg and New Zealand paid for construction of the WGS-9 satellite in a collaborative effort to join the U.S. military’s global communications network.
