Video: Change of command aboard International Space Station

Based upon an on-time launch Thursday, this is the timeline for Cygnus from liftoff through capture by the space station’s robotic arm.

Fresh off a series of three complex spacewalks to repair a $2 billion cosmic ray detector, the International Space Station’s crew is set to receive two robotic resupply freighters in the next week after launches from Florida’s Space Coast and the steppes of Kazakhstan.

The Antares rocket, Orbital ATK’s medium-class booster now with modern RD-181 engines, launches at 7:45 p.m. EDT (2345 GMT) from NASA’s Wallops Flight Facility on the eastern shore of Virginia.
