Snapshots from Atlas 5 launch

This photo gallery shows the commercial Cygnus cargo resupplier for the International Space Station on Monday at Kennedy Space Center being encapsulated in the United Launch Alliance Atlas 5 rocket’s payload fairing for the planned Dec. 3 liftoff.

The quartet touched down at the Launch and Landing Facility around 1:45 p.m. EST (1845 UTC). They’re set to launch aboard a SpaceX Falcon 9 rocket on Friday, March 1, at 12:04 a.m.

Blue Origin said Sunday that it lost a set of powerpack hardware for its BE-4 engine during a ground test mishap, dealing at least a minor setback to the development of a powerful U.S.-made propulsion system that United Launch Alliance says is the leading candidate to power the first stage of its next-generation Vulcan rocket.
