Orbital Sciences Corporation’s Antares rocket soared into partly cloudy Virginia skies this morning, carrying the first operational Cygnus resupply spacecraft into orbit. Liftoff from NASA’s Wallops Flight Facility occurred at 10:58 a.m. (14:58 UTC), with Cygnus separating about ten minutes later. NASA and Orbital reported that the spacecraft’s propulsion system had initialized and its solar arrays had been deployed at 11:24.

Cygnus will spend the next few days raising its orbit and conducting demonstration tasks, which include tests of its GPS and ability to free drift and abort. It is expected to arrive at the International Space Station on Sunday, with capture scheduled for 7:17 a.m. Orbital will be the second private company to visit the ISS under NASA's Commercial Orbital Transportation Services program, following three successful trips by SpaceX's Dragon capsule.
