Launching the sixth mission of the U.S. military’s super-secret X-37B spaceplane program, a United Launch Alliance Atlas 5 rocket lifted off Sunday morning from Cape Canaveral and successfully delivered its clandestine cargo to orbit.

This is the launch timeline to be followed by the Atlas 5 rocket’s ascent into orbit from Cape Canaveral with NASA’s Tracking and Data Relay Satellite-M. Launch is scheduled for Friday at 8:03 a.m. EDT (1203 GMT).

The world’s most powerful operational rocket flashed to life at 2:30 a.m. EDT (0630 GMT) Tuesday and climbed into a moonlit summer sky from pad 39A at NASA’s Kennedy Space Center in Florida, the same site where the Apollo 11 astronauts left Earth for their historic moon landing nearly 50 years ago.
