At the Baikonur Cosmodrome in Kazakhstan, NASA astronaut Peggy Whitson, Oleg Novitskiy of the Russian space agency Roscosmos, and Thomas Pesquet of ESA (European Space Agency) are preparing for launch to the International Space Station. They are scheduled to lift off today in a Soyuz MS-03 spacecraft at 3:20 p.m. EST (2:20 a.m. Nov. 18, Baikonur time).

Live coverage of the launch will begin at 2:30 p.m. on NASA Television and the agency’s website. Check out the NASA TV schedule online for information on how to watch live and replays.

The three crew members will join Expedition 50 Commander Shane Kimbrough of NASA and cosmonauts Sergey Ryzhikov and Andrey Borisenko, who have been aboard the complex since October. Whitson, Novitskiy and Pesquet will remain aboard the station until next spring. Kimbrough, Ryzhikov and Borisenko are scheduled to remain aboard the station until late February.

The Expedition 50 crew members will contribute to more than 250 experiments in fields such as biology, Earth science, human research, physical sciences and technology development.
