At the Baikonur Cosmodrome in Kazakhstan, NASA astronaut Jeff Williams and cosmonauts Oleg Skripochka and Alexey Ovchinin of Roscosmos are preparing for launch to the International Space Station. Their six-month journey will begin with a lift off in a Soyuz spacecraft at 5:26 p.m. EDT Friday, March 18 (3:26 a.m. on March 19 in Baikonur).

NASA Television will broadcast launch coverage live beginning tomorrow at 4:30 p.m. For the NASA TV schedule and where to watch live and replays, visit:

The incoming crew will join Expedition 47 Commander Tim Kopra of NASA and Flight Engineers Tim Peake of ESA (European Space Agency) and cosmonaut Yuri Malenchenko of Roscosmos. A separate trio returned to Earth on March 1, including one-year mission crewmates NASA astronaut Scott Kelly and cosmonaut Mikhail Kornienko of Roscosmos as well as cosmonaut Sergey Volkov. Kelly and Kornienko completed a historic 340-day mission aboard the station.

      Launch is scheduled when the space station’s orbit takes it over the launch site. When the rocket launches its ascent into space aligns it with the space station’s orbit over Earth.
