A United Launch Alliance Delta 4 rocket lifted off from Cape Canaveral at 8:26 p.m. EDT Friday (0026 GMT Saturday) with the U.S. Air Force’s tenth Wideband Global SATCOM satellite, extending the reach of the military’s highest-capacity satellite communications network.

United Launch Alliance technicians positioned the first stage for the next Atlas 5 rocket on a mobile launch platform Friday at Cape Canaveral, a key step in preparations for an October mission that will debut a new solid-fueled booster design.

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.
