ATLANTIC, Va.—A company contracted by NASA to deliver supplies to the International Space Station has scrubbed the launch of a test rocket from the East Coast.

High winds forced the cancellation of the launch of the unmanned Antares rocket planned for Saturday from Wallops Island on Virginia's Eastern Shore. Dulles-based Orbital Sciences Corp. plans to try again Sunday.

The planned launch is designed to test whether a practice payload could reach orbit and safely separate from the rocket.

Orbital is one of two companies contracted to supply the space station by NASA, which ended its shuttle program in 2011. California-based SpaceX completed its third supply run to the station last month.
