Live coverage: Two satellites lift off aboard Ariane 5

The U.S. Air Force fired a new rail-launched rocket into space from Hawaii at 10:45 p.m. EST Tuesday (0345 GMT Wednesday), but the Super Strypi vehicle failed about a minute after liftoff with 13 satellites on-board.

The launch of a United Launch Alliance Delta 4-Heavy rocket from Cape Canaveral was aborted three seconds before a planned liftoff at 3:28 a.m. EDT (0728 GMT). The rocket was set to loft a classified payload for the National Reconnaissance Office, the U.S. government’s spy satellite agency.

A $66 million NASA-funded science sensor package bolted on to a commercial communications satellite is ready for a ride toward a 22,000-mile-high orbital perch Thursday on a European Ariane 5 rocket, commencing a two-year mission surveying a rarely-studied region of Earth’s upper atmosphere.
