The Antares rocket launch is back on Sunday afternoon, as engineers and spectators look for the rocket to lift off from a launch pad at NASA's Wallops Flight Facility. The most recent check, at 10 minutes before launch, was positive.
The mission had been postponed twice this week, after a connecting cable came loose on Wednesday and unfavorable winds forced a one-day delay on Saturday. Officials believe the launch may be visible from sites all along the eastern U.S. coast.
Around 3:30 p.m. ET Sunday, the rocket was approved for launch and fueling of the vehicle began, NASA reported.
The NASA facility is located just behind the beach on Wallops Island on Virginia's Eastern Shore. Antares is a product of a joint development project between NASA and Orbital Sciences Corp., based in Virginia.
As NPR's Geoff Brumfiel reported Wednesday, a successful test would eventually make Orbital "the second private company after California's SpaceX to dock with the space station."
