Videos: Atlas 5 caps a generation of GPS launches

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.

Astronauts Doug Hurley and Bob Behnken arrived Wednesday at the Kennedy Space Center, ready for spacesuit and spacecraft fit checks, and some time off with their families before launching next week on the first crewed flight into orbit from U.S. soil since 2011.

A Chinese environmental research craft and an experimental Earth-imaging nanosatellite successfully launched Saturday aboard a Long March 2D rocket.
