At the Baikonur Cosmodrome in Kazakhstan, NASA astronaut Randy Bresnik, Sergey Ryazanskiy of Roscosmos and Paolo Nespoli of ESA (European Space Agency) are preparing for their launch to the International Space Station. Their journey to the station will begin with a lift off at 11:41 a.m. EDT Friday (9:41 p.m. in Baikonur). Live launch coverage will begin at 10:45 a.m. EDT on NASA Television and the agency’s website.

The three will join Expedition 52 Commander Fyodor Yurchikhin of Roscosmos and Flight Engineers Peggy Whitson and Jack Fischer of NASA. The Expedition 52 crew members will contribute to more than 250 experiments in fields such as biology, Earth science, human research, physical sciences and technology development.
