An unmanned Russian cargo spacecraft successfully docked with the Intentional Space Station early Wednesday.
The Progress 62 cargo ship, carrying more than 2.8 tons of food, fuel, and supplies, blasted off from the from the Baikonur Cosmodrome in Kazakhstan Monday.
Ahead of its arrival at the ISS, two U.S. crew members, Scott Kelly and Tim Kopra, left the orbiting laboratory for a three hour space walk to perform an assembly and maintenance operation.
Their primary task was to move the space station’s mobile transporter rail car a few centimeters from its stalled position so it could be latched in place before Wednesday’s docking.
