Video: Delta 2/SMAP pre-launch news conference

Members of the news media — reporters and photographers — witnessed the United Launch Alliance Delta 4-Heavy rocket lifted off from the ITL Causeway on Cape Canaveral Air Force Station, about 1.7 miles from the pad.

Engineers scrambled to keep NASA’s billion-dollar asteroid-bound OSIRIS-REx spacecraft on track for its launch last week in the aftermath of an explosion a mile away at SpaceX’s launch pad at Cape Canaveral.

It is a rocket like no other, a vehicle with a single solid-fuel booster mounted to its side, that will launch NASA’s OSIRIS-REx probe next month to bring back a sample of Asteroid Bennu.
