Video: Pegasus and CYGNSS pre-launch news conference

The International Space Station crew releases the Cygnus OA-7 commercial cargo ship from the Canadian robotic arm to begin free-flight away from the lab complex, completing 43-day visit that delivered supplies, food and science gear.

The Japanese space agency has delayed the planned Sept. 30 launch of an HTV space station cargo ship to repair a leak in the vehicle, clearing the way for Orbital ATK to slip the launch of its Cygnus supply ship from Aug. 22 to the second half of September to complete tests and analysis of its re-engined Antares rocket, officials said Wednesday.

Watch the post-launch press conference held at the Kennedy Space Center following the successful launch of an Atlas 5 carrying Orbital ATK’s Cygnus AO-6 cargo craft, which is headed to the International Space Station.
