Photos: Atlas 5 rocket soars from West Coast

United Launch Alliance fired an Atlas 5 rocket into space from Cape Canaveral at 9:14 a.m. EDT (1314 GMT) Sunday with the U.S. Air Force’s X-37B spaceplane, an automated reusable mini-space shuttle designed to host experiments for years in orbit, then return to Earth and land on a runway. A launch attempt Saturday was scrubbed by bad weather.

The Falcon 9 booster assigned to launch two NASA astronauts on an orbital test flight of SpaceX’s Crew Dragon capsule has been test-fired in Texas, but the schedule for the long-awaited mission remains unclear.

Two SpaceX Falcon 9 rocket launches will loft seven high-throughput broadband satellites for SES’s O3b mPower constellation in 2021, SES announced this week.
