The Soyuz capsule is scheduled to dock with the orbiting laboratory at 8:23 p.M. Moscow time (1723 GMT) today, about six-and-a-half hours after it lifted off from the Russian manned space launch facility on the steppes of Kazakhstan.
Aboard are Yuri Malenchenko, Timothy Kopra of NASA and Briton Timothy Peake, representing the European Space Agency.
The mission is to spend six months aboard the space station. Already aboard are Russians Sergey Volkov and Mikhail Korniyenko, along with American Scott Kelly.
