Cygnus OA-6: What’s onboard?

NASA has signed a $490 million agreement with the Russian government to ferry U.S. astronauts to and from the International Space Station in 2018 and 2019 as a hedge in case of delays to Boeing and SpaceX crew capsules.

These narrated videos show the pre-launch preparations that readied the United Launch Alliance Atlas 5 rocket and the Orbital ATK Cygnus commercial cargo-delivery spacecraft for flight and rolling to Complex 41 for liftoff to the International Space Station.

NASA and Northrop Grumman are expected to base the launch of an air-dropped Pegasus rocket with a NASA science satellite from Cape Canaveral later this year, after originally trying to get the mission into space from a remote island in the middle of the Pacific Ocean.
