Repost from nasa_marshall: A cool shot of United Launch Alliance's Delta IV booster as it is being loaded into the Mariner shipping vessel headed to the Cape for NASA Orion's first flight this fall. What an exciting day! Orion's flight on the Delta IV sets the stage for its eventual home on the Space Launch System, NASA's new heavy lift rocket set to launch in 2017.
