On May 13, 2014 at 22:36 UTC (on May 14, 2014 at 02:36 Moscow time) the Russian “Soyuz TMA-11M” spacecraft undocked from the Russian “Rassvet” (MIM 1) module of the International Space Station to deliver to Earth the 3 members of Expedition 39 – Russian cosmonaut Mikhail Tyurin, American astronaut Richard Mastracchio and Japanese astronaut Koichi Wakata.
On April 25, 2014 at 12:13 UTC the “Progress M-21M” unmanned supply spacecraft was docked again to the Russian “Zvezda” (Star) module of the International Space Station after a 2-day autonomous flight. The spacecraft was undocked from the ISS on April 23 to test the “Kurs-NA” docking system.
On April 23, 2014 at 13:56 UTC two American astronauts Richard Mastracchio and Steven Swanson began their spacewalk. They spent 1 hour and 36 minutes outside the International Space Station to replace a failed computer.
On April 23, 2014 at 08:58 UTC the “Progress M-21M” unmanned supply spacecraft was undocked from the Russian “Zvezda” (Star) module of the International Space Station. The spacecraft will perform an autonomous flight till April 25, 2014 and then it will be docked with the ISS again. The aim of the autonomous flight and the 2nd docking is to test the “Kurs-NA” docking system.
On April 20, 2014 at 14:06 UTC the private U.S. unmanned supply spacecraft, the Dragon (CRS-3 flight), was successfully docked to the International Space Station. The linkup operation was carried out by astronauts Koichi Wakata (Japan) with the help of the giant 17-meter Canadarm that had earlier (at 11:14 UTC) grabbed the Dragon capsule. The Dragon spacecraft was maneuvered into position and attached to a berthing port on the space station's Harmony module. The unmanned spacecraft delivered about 2,268 kilograms of supplies for the space station crew and for experiments being conducted aboard the ISS.
On April 18, 2014 at 19:25 UTC the "Falcon 9R” rocket-carrier was launched from the Cape Canaveral US Air Force Station in 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-3 flight) unmanned spacecraft on a third cargo resupply mission to the International Space Station. CRS means Commercial Resupply Services. The Dragon spacecraft is carrying about 2,268 kilograms of supplies for the space station crew and for experiments being conducted aboard the ISS. It is the 5th flight of a “Dragon” spacecraft and the 4th flight of a “Dragon” to the ISS.
On April 18, 2014 the “Progress M-22M” unmanned supply spacecraft were deorbiting. Non-burnt fragments of the spacecraft sank in the South part of the Pacific at 15:46 UTC. Since April 7, 2014 the spacecraft was in a controlled autonomous flight to conduct a scientific experiment "Radar-Progress”. The purpose of the experiment was to determine the spatial and temporal dependence of the density, temperature, ionic composition of local inhomogeneities in the ionosphere resulting from the on-board liquid rocket engines.
On April 09, 2014 at 21:14 UTC (on April 10 at 01:14 Moscow time) the Russian “Progress M-23M” unmanned supply spacecraft docked to the International Space Station. The spacecraft was docked to the Russian “Pirs” (Pier) module. The spacecraft carried about 2400 kilograms of cargo for the six-member ISS crew.
On April 09, 2014 at 15:26 UTC the “Progress M-23M” unmanned supply spacecraft was launched from Baykonur Cosmodrome to the International Space Station. The spacecraft was orbited by the “Soyuz-U” rocket-carrier.
On April 07, 2014 at 13:58 UTC the “Progress M-22M” unmanned supply spacecraft was undocked from the Russian “Pirs” (Pier) module of the International Space Station. The spacecraft is to be deorbited on April 18, 2014.
