On February 21, 2015 American astronauts Barry Wilmore and Terry Virts performed the spacewalk to install wiring needed for two new docking mechanisms that will be attached later this year for use by Boeing and SpaceX crew capsules. The astronauts installed 8 cables with the total length of about 100 meters. The EVA lasted 6 hours and 41 minutes.

This was the second spacewalk for Wilmore and the first for Virts. With the completion of Saturday’s work, 120 astronauts and cosmonauts representing nine nations have logged 1,159 hours and eight minutes of spacewalk time, or 48.3 days.

On February 17, 2015 at 16:57 UTC the Russian “Progress M-26M” unmanned supply spacecraft docked to the International Space Station. The spacecraft was docked to the Russian “Zvezda” (Star) module. The spacecraft carried about 2400 kilograms of cargo for the six-member ISS crew.

On February 17, 2015 at 11:00 UTC the “Progress M-26M” unmanned supply spacecraft was launched from Baykonur Cosmodrome to the International Space Station. The spacecraft was orbited by the “Soyuz-U” rocket-carrier.

On February 15, 2015 the European ATV-5 " Georges Lemaître” unmanned supply spacecraft was deorbited. Non-burnt fragments of the spacecraft sank in the South part of the Pacific at about 18:04 UTC.  It was the last flight of the ATV series spacecraft.

On February 14, 2015 at 13:42 UTC the European ATV-5 " Georges Lemaître” unmanned supply spacecraft was undocked from the Russian "Zvezda” ("Star”) module of the International Space Station.

On February 10, 2015 the station's robotic arm removed the “Dragon” unmanned supply spacecraft from a berthing port on the Harmony module of the International Space Station. Controlled by ground controllers and then astronaut Samantha Cristoforetti (Italy), the robotic arm let go of the "Dragon” resupply vehicle at 19:10 UTC

On February 11, 2015 at 00:44 UTC the "Dragon” capsule splashed down in the Pacific Ocean at about 260 miles (480 kilometers) southwest of Long Beach, California, USA. The Dragon delivered to Earth about 1700 kilograms (3700 pounds) of cargo. It was the "SpaceX CRS-5” mission. CRS means Commercial Resupply Services.

On February 05, 2015 at 12:45 UTC the AESP-14 satellite was deployed from the International Space Station. It is a brazilian 1U CubeSat, which was developed as a scientific and technological cooperation basically between the ITA (Instituto Tecnológico de Aeronáutica) and INPE (Instituto Nacional de Pesquisas Espaciais). The satellite was sent to the International Space Station (ISS) as cargo on board the Dragon (CRS-5) supply spacecraft in January 2015.

On January 12, 2015 at 13:56 UTC the private U.S. unmanned supply spacecraft, the Dragon (CRS-5 flight), was successfully docked to the International Space Station. The linkup operation was carried out by American astronauts Barry Wilmore with the help of the giant 17-meter Canadarm. The capture with Canadarm-2 occurred at 10:54 UTC. 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 2.6 tons of supplies for the space station crew and for experiments being conducted aboard the ISS.

On January 10, 2015 at 09:47 UTC the "Falcon 9” 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-5 flight) unmanned spacecraft on a firth cargo resupply mission to the International Space Station. CRS means Commercial Resupply Services. The Dragon spacecraft is carrying about 2,317 kilograms of supplies for the space station crew and for experiments being conducted aboard the ISS. It is the 7th flight of a “Dragon” spacecraft and the 6th flight of a “Dragon” to the ISS.

On January 01, 2015, Boris Vladimirovich MORUKOV, pilot-cosmonaut of Russia, passed away at the age of 64.

Morukov, a doctor and a former cosmonaut, was project director of the unprecedented Mars-500 simulation, in which an international team of six men spent 520 days in isolation to simulate a flight to Mars.
