Live coverage: Dragon cargo craft arrives at space station

Kurt Eberly, who helps lead the Antares rocket program at Orbital ATK, recently spoke with Spaceflight Now about the launcher’s return-to-flight with newly-built engines later this year.

Astronauts on the International Space Station are eager to begin unpacking 2.6 tons of supplies and experiments — including a package of belated Christmas gifts — after delivery aboard a SpaceX Dragon cargo capsule Monday.

This mission follows a similar model of processing used during the Rapid Response Trailblazer (RRT-1) mission, which saw the launch of the GPS 3 Space Vehicle 07 (SV-07) spacecraft on a Falcon 9 instead of a United Launch Alliance Vulcan rocket as originally planned.
