Taking a U.S. national security satellite payload into space is the primary objective of the 70th Atlas 5 booster that will be launched Wednesday.

SpaceX launched a Falcon 9 rocket from California’s Central Coast at 10:42:18 a.m. PST (1:42:18 p.m. EST; 1842:18 GMT) Sunday with the Jason 3 oceanography satellite. A secondary objective of the mission to recover the first stage on a barge in the Pacific Ocean failed.

The U.S. military’s highest capacity communications satellite ever built was successfully launched into space tonight, departing Cape Canaveral aboard a United Launch Alliance Delta 4 rocket at 6:53 p.m. EST (2353 GMT).
