A three-man crew blasted off from a space center in southern Kazakhstan Tuesday morning on board a Russian-made Soyuz craft for a four-and-half-month stay at the International Space Station.

NASA astronaut Joseph Acaba and Russian cosmonauts Gennady Padalka and Sergei Revin set off from the Baikonur facility as scheduled at 9:01 a.m. local time (0301 GMT).

Russia's space agency says the craft is due to dock with the space station Thursday morning Moscow time and will join the three astronauts currently staying at the orbiting laboratory.

The crew, which is being commanded by retired 53-year old Russian Air Force Col. Padalka, will immediately get to work preparing for the arrival next week of privately owned SpaceX's Dragon Capsule. It will be the first time a private company has launched space station supplies.

The space station is currently occupied by Russian cosmonaut Oleg Kononenko, NASA astronaut Don Pettit and Holland's Andre Kuipers.
