Photos: Tuesday’s Atlas 5 rollout

Two months after a first test-firing ended prematurely, NASA plans to ignite the core stage of the first Space Launch System heavy-lift rocket again Thursday for an eight-minute burn to confirm it is ready for shipment to the Kennedy Space Center for launch preparations.
