English: Russian cosmonaut Yuri Malenchenko manually docked the Soyuz TMA-19M spacecraft on Dec. 15, 2015 to the International Space Station's Rassvet module after an initial automated attempt was aborted. Malenchenko took control of the Soyuz, backed it away from the station to assess the Soyuz' systems, then re-approached the complex for the manual docking. Flight Engineer Tim Kopra of NASA and Flight Engineer Tim Peake of ESA (European Space Agency) flanked Malenchenko as he brought the Soyuz to the Rassvet port for the start of a six-month mission. The solar array from the docked Orbital AT Cygnus cargo vehicle is also in view at right.
After leak checks were conducted on both sides of the docking interface, hatches were opened and Malenchenko, Kopra and Peake were greeted by Expedition 46 Commander Scott Kelly of NASA and Flight Engineers Mikhail Kornienko and Sergey Volkov of the Russian Federal Space Agency (Roscosmos). The arrival of Kopra, Malenchenko and Peake returns the station's crew complement to six. The three join Expedition 46 Commander Scott Kelly of NASA and Flight Engineers Sergey Volkov and Mikhail Kornienko of Roscosmos. During more than five months on humanity’s only microgravity laboratory, the Expedition 46 crew members will conduct more than 250 science investigation in fields including biology, Earth science, human research, physical sciences and technology development. Kopra, Malenchenko and Peake will remain aboard the station until early June 2016.
