At the Baikonur Cosmodrome in Kazakhstan, NASA astronaut Kate Rubins, cosmonaut Anatoly Ivanishin of the Russian space agency Roscosmos, and astronaut Takuya Onishi of the Japan Aerospace Exploration Agency (JAXA) are preparing for launch to the International Space Station. They are scheduled to lift off in a Soyuz spacecraft today at 9:36 p.m. EDT (7:36 a.m. Baikonur time, July 7). All three will spend approximately four months on the orbital complex, returning to Earth in October.

Live launch coverage will begin at 8:30 p.m. EDT on NASA Television and the agency’s website.

The three will join Expedition 48 Commander Jeff Williams of NASA and Flight Engineers Oleg Skripochka and Alexey Ovchinin of Roscosmos. The Expedition 48 crew members will spend four months contributing to more than 250 experiments in fields such as biology, Earth science, human research, physical sciences and technology development.

NASA TV coverage will begin at 11:30 p.m. Friday, July 8 for docking to the space station’s Rassvet module at 12:12 a.m. Saturday, July 9. Hatches are scheduled to open about 2:50 a.m. Saturday, July 9, with NASA TV coverage resuming at 2:30 a.m.
