On April 10, 2017 at 07:57 UTC the Russian “Soyuz MS-02” spacecraft undocked from the International Space Station to deliver to Earth the 3 members of Expedition 50 – Russian cosmonauts Sergey Ryzhikov and Andrei Borisenko as well as American astronaut Robert Kimbrough.
On April 8, 2017, Georgy Mikhajlovich Grechko, pilot-cosmonaut of USSR, passed away at the age of 85. A retired cosmonaut and twice Hero of the Soviet Union, Georgy Grechko, performed three journeys into space – one of which was a record. The cosmonaut died on Saturday morning “because of age and a vast number of chronic illnesses,” his daughter Olga told TASS. In 1978 Georgy Grechko was the first officially appointed space postmaster.
Russian President Vladimir Putin expressed his deepest condolences to the family and friends of cosmonaut Georgy Grechko on his passing.
On March 30, 2017, American astronauts Robert Kimbrough and Peggy Whitsonperformed the spacewalk to continue work to set up a second docking port for U.S. crew ferry spaceships. They also installed an upgraded computer relay box and protective shielding. It was the 6th spacewalk for Kimbrough and the 9th for Whitson. Peggy Whitson, a veteran of two earlier long-duration station visits, set a new record for cumulative spacewalk time by a female astronaut, surpassing Sunita Williams’ mark of 50 hours and 40 minutes. When the spacewalk concluded, Whitson’s total EVA time stood at 53 hours and 22 minutes, moving her up to fifth on the list of most experienced spacewalkers.
On March 24, 2017, American astronauts Robert Kimbrough and French astronaut Thomas Pesquet performed the spacewalk. The spacewalkers disconnected cables and electrical connections between the “PMA-3” docking adapter and the station’s “Tranquility” module to prepare for the relocation of the docking adapter to the space-facing port on the “Harmony” module, in advance of the delivery of a new docking adapter to the complex next year for commercial crew spaceships owned by Boeing and SpaceX. Kimbrough and Pesquet also lubricated a latching end effector on the Dextre robot, a two-armed handyman provided by the Canadian Space Agency, inspected a radiator valve to look for signs of a small ammonia leak, and replaced cameras outside the Japanese lab module. The EVA lasted six-and-a-half hour. It was the fifth spacewalk for Kimbrough and the second for Pesquet.... Read more »
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 06, 2017 at 10:45 UTC the American Lemur-2 “Trutna” and Lemur-2 “‘TrutnaHD” mini-satellites and at 18:20 UTC the American TechEdSat-5 (TES-5, Technical and Educational Satellite) satellite were launched from the International Space Station.
On February 24, 2017 at 08:30 UTC the Russian “Progress MS-05” unmanned supply spacecraft docked to the International Space Station. The spacecraft was docked to the Russian “Pirs” module. The spacecraft delivered about 2500 kilograms of cargo for the six-member ISS crew.
On February 23, 2017 at 13:12 UTC the private U.S. unmanned supply spacecraft, the "Dragon” SpX-10 (CRS-10 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 French astronaut Thomas Pesquet at 10:44 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 10th time a Dragon spaceship has reached the space station, counting a demonstration flight in 2012.
On February 22, 2017 at 05:58 UTC the “Progress MS-05” unmanned supply spacecraft was launched from Baykonur Cosmodrome to the International Space Station. The spacecraft was orbited by the “Soyuz-U” rocket-carrier. It was the last launch of the rocket-carrier of the “Soyuz-U” version.
