Russian cargo ship docks at International Space Station

An unmanned Russian cargo ship has docked successfully at the International Space Station, delivering a fresh batch of supplies for the crew.

The Russian space agency Roscosmos said the Progress spacecraft moored at the station on February 15 in automatic mode, bringing 2.7 metric tons (3 tons) of food, fuel and instruments. It was launched on February 13 from the Russian space complex in Baikonur, Kazakhstan.

The launch initially set for Sunday was postponed at the very last minute due to an unspecified glitch. And instead of the original plan to test a new regime for docking less than four hours after launch, it performed a standard two-day approach maneuver. There are six astronauts aboard the space station — three Americans, two Russians and one from Japan.
