On May 27, 2015 at 21:16 UTC the “Ariane-5ECA” rocket-carrier was launched from Kourou Cosmodrome in French Guiana. The rocket orbited the “DirecTV-15” and the “Sky Mexico-1” communications satellites. DirecTV 15 and Sky Mexico-1 are beginning missions expected to last at least 15 years.

On May 21, 2015 at 16:42 UTC the "Dragon” capsule splashed down in the Pacific Ocean at about 250 kilometers southwest of Long Beach, California, USA. The Dragon delivered to Earth about 1400 kilograms (3100 pounds) of cargo. It was the "SpaceX CRS-6” mission. CRS means Commercial Resupply Services.

On May 21, 2015 the station's robotic arm removed the “Dragon” (SpaceX CRS-6) unmanned supply spacecraft from a berthing port on the Harmony module of the International Space Station. Controlled by ground controllers and then astronaut Scott Kelly, the robotic arm let go of the "Dragon” resupply vehicle at 11:04 UTC.
