Video: Atlas 5 rocket launches space station cargo mission

A Soyuz booster vaulted into a sunset sky over French Guiana on Wednesday evening, arcing north from the jungle spaceport in South America with six satellites to inaugurate OneWeb’s global broadband network.

An Ariane 5 rocket emerged from its vertical assembly building Monday and rolled along dual rail tracks for a 1.7-mile (2.7-kilometer) journey to its launch pad at the Guiana Space Center on the northern coastline of South America, moving into position for blastoff Wednesday with four Galileo navigation satellites.

The two Geosynchronous Space Situational Awareness Program, or GSSAP, satellites for the U.S. military are mounted aboard the United Launch Alliance Delta 4 rocket. Liftoff is planned for Aug. 19 from Cape Canaveral.
