Live coverage: Two satellites lift off aboard Ariane 5

Four satellites tucked inside the tip of a Soyuz rocket lifted off Thursday, heading for a 5,000-mile-high orbit to expand the reach of O3b’s broadband communications network. Liftoff from the European-run spaceport in French Guiana occurred at 1:37 p.m. EST (1837 GMT).

A United Launch Alliance Atlas 5 rocket lifted off from Cape Canaveral today at 7:42 p.m. EST (0042 GMT) to deploy the U.S. military’s SBIRS GEO Flight 3 observatory, equipped with advanced telescopic infrared vision to spot enemy missile launches, for early warning surveillance.

A pair of television broadcast satellites for AT&T and Eutelsat rocketed into orbit Thursday evening, riding a European Ariane 5 launcher into space in a spectacular sunset launch from the Guiana Space Center on the northeastern coast South America.
