Live coverage: Two satellites lift off aboard Ariane 5

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.

Arianespace will fit in a bonus launch of a Soyuz rocket from French Guiana in May to deliver two more European Galileo navigation satellites to orbit, giving the French launch services firm 12 missions on its 2016 manifest, officials said Thursday.

Firing off the launch pad with more than a half-million pounds of thrust, a Vega rocket soared into space Monday night from French Guiana with Europe’s Sentinel 2B environmental satellite.
