AKIPRESS.COM - Three astronauts aboard a Soyuz spacecraft successfully launched towards the International Space Station on Thursday after a two-month delay caused by a Russian rocket failure.

The spacecraft blasted off on schedule from Baikonur cosmodrome in Kazakhstan at 2102 GMT, carrying cosmonaut Oleg Kononenko, US astronaut Kjell Lindgren, and Kimiya Yui of Japan.

As the Soyuz TMA 17M rocket surged skywards from the launch pad, the fire from the boosters set the inky night sky aglow.

Russian officials breathed a sigh of relief, with the space agency Roscosmos saying that the third stage of the Soyuz rocket separated on time and the crew were "feeling well."

"Everything is okay, everything is according to plan," said veteran cosmonaut Fyodor Yurchikhin, providing live commentary of the liftoff on television.

All eyes were trained on the launch after Russia was in May forced to delay the astronauts´ departure because a supply ship had crashed back to Earth following a rocket failure.

Russia put all space travel on hold after the failure of the unmanned Progress freighter taking cargo to the ISS in late April.

The doomed ship lost contact with Earth and burned up in the atmosphere. The failure, which Russia has blamed on a problem in a Soyuz rocket, also forced a group of astronauts to spend an extra month aboard the ISS.

A workhorse of space that dates back to the Cold War, the Soyuz is used for manned and unmanned flights. (AFP)
