Live coverage: Ariane 5 lifts off on its first Galileo launch

The United Launch Alliance Delta 4 rocket sits peacefully inside its mobile service gantry on Tuesday afternoon, one day before its scheduled launch of the GPS 2F-9 navigation satellite.

An Indian rocket lifted off with two British-built Earth-imaging satellites at 1638 GMT (12:38 p.m. EDT) Sunday — one developed with the financial backing of the UK government to demonstrate radar reconnaissance technology, and another destined for use by a commercial imaging company in Asia.

Boeing Satellite Systems, Airbus Defense and Space and Orbital ATK have won orders from Luxembourg-based satellite operator SES for three new communications spacecraft for launch in 2017.
