Photos: Tuesday’s Atlas 5 rollout

The United Launch Alliance Atlas 5 rocket, standing 194 feet tall and and weighing a million pounds, unleashes 1.6 million pounds of thrust from its main engine and two side-mounted solid boosters to launch the secret NROL-52 payload for the U.S. National Reconnaissance Office from Cape Canaveral.

The next launch of United Launch Alliance’s Atlas 5 rocket with the U.S. Air Force’s fifth Advanced Extremely High Frequency communications satellite, previously scheduled for Thursday, has been delayed to no earlier than July 12 to replace a failed battery on the vehicle.

Two ion-driven communications satellites launched from Cape Canaveral on March 1 have begun novel maneuvers using electric propulsion to reach operating posts 22,300 miles over the equator.
