Russia successfully launched a supply craft to the International Space Station on Friday following the recent failure of two other launches. The unmanned Progress craft, to dock with the station on Sunday at approximately 10 am (0700 GMT), is carrying 2.4 metric tons of fuel, oxygen, food, water and other supplies, dpa quoted Russia's space agency Roscosmos as saying in a statement. The cargo has been anxiously awaited after two previous launches of supply ships to the space station - in April by the Russians and just days ago by the Americans - failed.
