Delta IV Heavy arrives at KSC

The United Launch Alliance barge Delta Mariner glides past the jetties as it enters Port Canaveral in Florida on March 6, 2014. The barge is carrying two of the booster stages for the Delta IV Heavy rocket slated for Orion's Exploration Flight Test-1, or EFT-1. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep-space return velocities.
