Cargo ship docks at space station

An unmanned Japanese cargo ship arrived at the International Space Station Thursday with more than three tonnes of food and supplies.

The Kounotori2 H-II Transfer Vehicle, also known as HTV2, was grappled by Canadarm2, the station's robotic arm, shortly before 7 a.m. ET.

NASA astronaut Cady Coleman and European Space Agency astronaut Paolo Nespoli used the arm to move the ship to the Earth-facing port of the station's Harmony module, where it finally docked.

The ship launched from Tanegashima Space Center in southern Japan Saturday.

It is scheduled to be filled with trash, detached from the station and sent to burn up in the Earth's atmosphere at the end of March.

HTV2 was the second unpiloted Japanese cargo ship to supply the station.
