Video: OA-7 Cygnus freighter arrives at its orbital destination

A Northrop Grumman Antares rocket powered off its launch pad at Wallops Island, Virginia, on Feb. 20 with a Cygnus supply ship heading for the International Space Station.

A SpaceX Dragon capsule is wrapping up a month-long mission Saturday. The spaceship departed the International Space Station at 9:23 a.m. EDT (1323 GMT), and splashed down in the Pacific Ocean at approximately 3 p.m. EDT (1900 GMT) with nearly two tons of experiment specimens and hardware, including a habitat of mice and Robonaut 2, an experimental humanoid robot in need of repairs.

The first pair of new Russian main engines for Orbital ATK’s modernized Antares rocket has arrived at the company’s Virginia launch base as engineers prepare to return the commercial booster to flight after a catastrophic failure last year.
