The three astronauts lifted off from the Baikonur Cosmodrome in Kazakhstan for a two-day trip to the International Space Station and will join three more astronauts who have been there since September.
A trio of US and Japanese astronauts and a Russian cosmonaut blasted off from Kazakhstan on Sunday for a two-day trip to the International Space Station, a NASA TV broadcast showed.
Commander Anton Shkaplerov of Roscosmos and flight engineers Norishige Kanai of Japan Aerospace Exploration Agency and Scott Tingle of NASA lifted off from the Baikonur Cosmodrome at 1:21 p.m. local time (0721 GMT/0221 EST).
The crew will gradually approach the station, which orbits about 400 km (250 miles) above Earth, for two days before docking.
Shkaplerov, Kanai and Tingle will join Alexander Misurkin of Roscosmos and Mark Vande Hei and Joe Acaba of NASA, who have been aboard the orbital outpost since September.
Onboard cameras showed crew members making thumbs-up gestures after the blast-off. Also visible was a stuffed dog toy chosen by Shkaplerov's daughter to be the spacecraft's zero-gravity indicator.
Soyuz was safely in orbit about 10 minutes after the launch.
