Live coverage: Two satellites lift off aboard Ariane 5

A United Launch Alliance Atlas 5 rocket blasted off from Cape Canaveral at 12:13 p.m. EDT (1613 GMT) Saturday to deploy a new Global Positioning System satellite.

A European Ariane 5 rocket, burning a cryogenic mixture of liquid hydrogen and liquid oxygen, thundered into the sky over French Guiana at dusk Tuesday with two communications relay satellites to serve the Arab world and India.

A four-stage Vega rocket streaked into space Tuesday night from French Guiana, hauling two Israeli-made satellites into polar orbit on military surveillance and environmental research missions.
