Russia's Mission Control has failed to stabilize a cargo ship spinning out of control in orbit, but says it has not yet given up on saving the unmanned spacecraft.

The Progress M-27M was launched Tuesday and was scheduled to dock at the International Space Station six hours later to deliver 2.5 tons of supplies, including food and fuel.

But flight controllers were unable to receive data from the spacecraft, which had entered the wrong orbit.

Mission Control spokesman Sergei Talalasov told the Interfax news agency on Wednesday that flight controllers were still trying to restore communication with the Progress.

Russia's space agency and NASA both said the six crew members on board the orbiting space station have sufficient supplies and are in no danger.
