Frank Culbertson, a former shuttle and station astronaut and now head of Orbital ATK’s space systems group, spoke with Spaceflight Now’s Stephen Clark on the sidelines of the 2015 International Symposium for Personal and Commercial Spaceflight.
The sixth commercial cargo delivery by Orbital ATK’s Cygnus spacecraft, and the first using an Antares rocket since a launch failure in 2014, will carry more than 5,000 pounds of equipment to the International Space Station.
The Atlas 5 rocket emerges Monday from the Vertical Integration Facility for rollout to Complex 41 at Cape Canaveral in preparation to launch the Orbital ATK Cygnus resupply ship to the International Space Station.
