NASA hopes to resume commercial shipments this week to the International Space Station after months of frustrating delay. The last successful U.S. supply run was in April. Russia and Japan have managed to fill the gap, but the 250-mile-high pantry isn't as full as it should be.

An unmanned Atlas V rocket reached the launch site Wednesday. It is to lift off Thursday evening with 7,400 pounds of supplies packed into the capsule Cygnus, named after the swan constellation.

The Virginia-based Orbital ATK Inc. is launching Cygnus from Cape Canaveral. Its Virginia launchpad was damaged in a 2014 explosion.

NASA's other contracted shipper, SpaceX of California, has been grounded since a failed launch in June. - AP
