An American astronaut and two Russian cosmonauts are poised to launch to the International Space Station tonight on a Russian rocket.
The trio is slated to lift off Thursday (Oct. 7) at 7:10 p.m. EDT (2310 GMT) from Kazakhstan's Baikonur Cosmodrome. The spaceflyers will ride a new model of the tried-and-true Russian Soyuz spacecraft, the TMA-01M, which features new guidance, navigation, control and data processing systems, and an improved cooling device for the electronics.
The crew is launching just days after the 53rd anniversary of the launch of Sputnik, the world's first man-made satellite, which occurred on Oct. 4, 1957. Indeed, their Soyuz will even blast off from the very same launch pad.
NASA astronaut Scott Kelly and cosmonauts Alexander Kaleri and Oleg Skripochka are set to take up long-term posts as members of the station's Expedition 25 crew. Kelly has a twin brother, Mark, who is also an astronaut and is due to fly aboard the space shuttle Endeavour on the STS-134 mission in February.
The new station crew is set to dock at the orbiting outpost's rooftop Poisk module on Saturday at 8:02 p.m. EDT (0002 GMT Sunday). They will join the outpost's existing Expedition 25 crew – station commander Doug Wheelock of NASA and flight engineers Fyodor Yurchikhin of Russia and Shannon Walker of NASA.
In November, half of the station's crew will return to Earth and Kelly will take command of the outpost to begin the Expedition 26 mission.
"It's a real privilege to be part of this crew and to be part of something that has been such a successful program to date – the International Space Station," Kelly said during a recent press briefing. "We're finishing up the assembly of the space station and it's really time to start ramping up the science we do."
