Watch a SpaceX rocket launch light up night sky in Pismo Beach
UPDATE, 5:45 p.m. Wednesday
According to ULA, the Delta IV Heavy rocket launch set for Wednesday evening has been scrapped after inspection found a hydrogen leak on one of the engine sections.
The rocket launch is now planned for Wednesday at 5:44 p.m., the agency said.
The rocket will carry a top-secret payload — a National Reconnaissance Office spacecraft — into orbit for a mission dubbed NROL-71, according to previous Tribune reports.
The team tried twice to launch the rocket earlier this month, but both times were foiled by technical glitches.
Air Force weather forecasters indicated an 80 percent chance of favorable weather conditions for the Wednesday launch.
