Orbital Sciences Corp. yesterday launched its 130-foot Antares rocket for the first time, a milestone in the company’s plans to deliver cargo to the International Space Station.

The unmanned rocket lifted off from the National Aeronautics and Space Administration’s Wallops Flight Facility on Virginia’s Eastern Shore. Orbital is seeking to follow Elon Musk’s Space Exploration Technologies Corp., or SpaceX, which last May became the first company to dock a commercial craft at the station.
