Live coverage: Two satellites lift off aboard Ariane 5

Follow the key events of the Soyuz rocket’s ascent into orbit from the Guiana Space Center with two satellites for Europe’s Galileo navigation system.

Europe’s Sentinel 2A land imaging satellite designed to glimpse cities, farms and forests from orbit launched aboard a Vega rocket. The 2,500-pound satellite lifted off at 0151:58 GMT Tuesday (9:51:58 p.m. EDT Monday).

An Ariane 5 rocket launch Tuesday added four more navigation satellites to Europe’s Galileo network with an on-target deployment following liftoff from a jungle spaceport on the northeastern coast of South America.
