A Northrop Grumman Antares rocket rolled out of its hangar Monday night, riding a self-propelled transporter for a mile-long trip to launch pad 0A on Wallops Island, Virginia, for a predawn liftoff Thursday with a Cygnus supply ship heading for the International Space Station.

A Russian Soyuz rocket blasted off from Kazakhstan Friday, boosting a three-man crew into orbit for a six-hour flight to the International Space Station.

This is the post-launch news briefing from NASA’s Wallops Flight Facility held after the successful return to flight by the Orbital ATK Antares rocket that delivered the Cygnus cargo ship into space.
