Live coverage: Soyuz crew capsule departs station, lands in Kazakhstan

Three space station crew members made final preparations Friday for undocking and landing in Kazakhstan early Saturday to close out a 186-day stay in orbit.

These video replays show the liftoff of the Soyuz rocket carrying Oleg Kononenko, David Saint-Jacques and Anne McClain away from the Baikonur Cosmodrome in Kazakhstan, toward a rendezvous with the International Space Station around six hours later.

Two NASA astronauts and an Italian flight engineer took shelter in the space station’s Russian segment Wednesday as mission control analyzed a possible leak of toxic ammonia coolant aboard the complex. Initial data indicated it was likely a false alarm.
