Snapshots from Atlas 5 launch

The 200th Atlas-Centaur rocket, history some 52 years in the making, will blast off Tuesday from Cape Canaveral to deliver a U.S. Navy mobile communications satellite into orbit.

The ocean-sailing ship that transports rocket stages from United Launch Alliance’s factory to U.S. launch sites completed its latest voyage overnight, pulling into port to deliver the Atlas 5 that will send a cargo freighter to the International Space Station in March.

A new launch date has been established — June 9 — for the Delta 4-Heavy rocket to carry a classified satellite into space for U.S. national security needs.
