On September 2, 2017 at 21:58 UTC (on September 3 at 00:58 Moscow time) the Russian “Soyuz MS-04” spacecraft undocked from the International Space Station to deliver to Earth the 3 members of Expedition 52 – Russian cosmonaut Fyodor Yurchikhin, American astronauts Jack Fisher and Peggy Whitson.
On August 17, 2017, Russian cosmonauts Fyodor Yurchikhin and Sergey Ryazansky performed the extra vehicle activities (EVA – spacewalk). The cosmonauts launched five small science and technology satellites overboard and spent the rest of the spacewalk servicing external experiments and carrying out routine but time-consuming inspections and maintenance. They also installed 10 temperature sensors on the “Poisk” module and serviced another external experiment. The EVA lasted 7 hours and 34 minutes. It was the 9th EVA overall for Yurchikhin and the 4th for Ryazanskiy.
On August 16, 2017, the private U.S. unmanned supply spacecraft, the "Dragon” SpX-12 (CRS-12 flight), was successfully docked to the International Space Station. The linkup operation was carried out with the help of the giant 17-meter Canadarm. The capture with Canadarm-2 was performed by American astronaut Jack Fisher at 10:52 UTC. The Dragon spacecraft was maneuvered into position and attached to a berthing port on the space station's Harmony module. This docking marked the 12th time a Dragon spaceship has reached the space station, counting a demonstration flight in 2012.
On August 14, 2017 at 16:31 UTC the "Falcon 9” rocket-carrier was launched from LP-39A of the Kennedy Space Center at Cape Canaveral, Florida. The launch was performed by the "SpaceX” private company supported by the 45th Space Wing of US Air Force. US private company SpaceX launched its "Dragon” (CRS-12 flight also known as SpX-12) unmanned spacecraft on a cargo resupply mission to the International Space Station. CRS means Commercial Resupply Services. It is the 13th successful flight of a “Dragon” spacecraft and the 12th successful flight of a “Dragon” to the ISS.
On July 29, 2017 at 00:55 Moscow time (on July 28 at 21:55 UTC) the Russian "Soyuz MS-05” spacecraft docked with the Russian “Rassvet” (MIM-1) module of the International Space Station.
The spacecraft delivered 3 new members of Expedition 52 to the ISS, Russian cosmonaut Sergey Ryazansky, American astronaut Randolph Bresnik and Italian astronaut Paolo Nespoli. The new comers joined current ISS expedition members – Russian cosmonaut Fyodor Yurchikhin, American astronauts Peggy Whitson and Jack Fisher.
On July 3, 2017 at 12:12 UTC the "Dragon” capsule splashed down in the Pacific Ocean. The Dragon delivered to Earth about 1900 kilograms of cargo. It was the "SpaceX CRS-11” mission. CRS means Commercial Resupply Services. It was the 11th flight of Dragon to the ISS with docking. The return marked the first time a Dragon capsule has splashed down at night.
On July 2, 2017 at 18:00 UTC the station's robotic arm removed the “Dragon” SpX-11 (CRS-11 flight) unmanned supply spacecraft from a berthing port on the Harmony module of the International Space Station. On July 3, 2017 at 06:41 UTC, the “Dragon” departed the Station, when astronaut Jack Fischer commanded the station’s robotic arm to release the spacecraft.
On June 14, 2017 at 09:20 UTC the “Progress MS-06” unmanned supply spacecraft was launched from Baykonur Cosmodrome to the International Space Station. The spacecraft was orbited by the “Soyuz-2.1A” rocket-carrier.
On June 11, 2017 at 13:38 UTC the US "Cygnus” (CRS OA-7 “John Glenn”) unmanned supply spacecraft was deorbited. The spacecraft re-entered the atmosphere and burned up over the South Pacific Ocean. Packed with trash and other equipment tagged for disposal, an Orbital Sciences Corp. “Cygnus” spacecraft plunged back into the atmosphere over the uninhabited Pacific Ocean. It was the 7th flight of "Cygnus” to the ISS.
