Glitch delays astronauts' arrival

A software glitch on a Russian spacecraft heading to the International Space Station has delayed the arrival of three astronauts.

Nasa said the crew was in no danger, and the US-Russia space partnership was strong despite tensions over Ukraine.

The Soyuz spacecraft carrying Russians Alexander Skvortsov and Oleg Artemyev and Nasa's Steve Swanson blasted off successfully and was scheduled to dock six hours later. But because of the glitch, the arrival was pushed back.

Since the retirement of the US space shuttle fleet in 2011, Nasa has depended on the Russian spacecraft to ferry crews to the orbiting outpost and is paying Russia nearly 71 million dollar (£43 million) per seat. This co-operation has continued despite tensions over Russia's annexation of Crimea and US calls for harsher sanctions on Russia.

Nasa Administrator Charles Bolden repeatedly has said that the conflict in Ukraine would have no effect on the US-Russian partnership.

As recently he reiterated on his blog that while Nasa continues to co-operate successfully with Russia, it wants to get its own capacity to launch crews as quickly as possible. Nasa is trying to speed up private American companies' efforts to launch crews into orbit, but it needs extra funding.

The Soyuz booster rocket lifted off as scheduled at 3.17am local time from the Russian-leased Baikonur cosmodrome in Kazakhstan. It entered a designated orbit about 10 minutes after the launch and was expected to reach the space station in six hours. All onboard systems were working flawlessly, and the crew was feeling fine.

Nasa and Roscosmos, Russia's space agency, said shortly before the planned docking that the arrival had been delayed after a 24-second engine burn that was necessary to adjust the Soyuz spacecraft's orbiting path "did not occur as planned".

The crew is in no danger, but will have to wait another day for the Soyuz TMA-12M to arrive and dock at the space station, Nasa said.

Roscosmos chief Oleg Ostapenko said that the glitch occurred because of a failure of the ship's orientation system. The crew is in good spirits and they have taken off their space suits to prepare for the long flight, Mr Ostapenko said in remarks carried by Russian news agencies.

The Russian official said the crew is now working to adjust the spacecraft to the correct orbit for the docking.

Until last year, Russian spacecraft used to routinely travel two days to reach the orbiting laboratory. It would have been only the fifth time that a crew would have taken the six-hour "fast-track" route to the station.
