Photos: Delta 4 awaits blastoff

A pair of innovative satellites for ViaSat and Eutelsat, valued at approximately $800 million, are scheduled to lift off Thursday on an Ariane 5 rocket from French Guiana, hauling the heaviest and costliest commercial payload ever launched.

Boeing’s Starliner spacecraft parachuted to an airbag-cushioned landing in New Mexico on Dec. 22 to conclude an abbreviated two-day test orbital test flight that accomplished many objectives, but missed a planned rendezvous and docking with the International Space Station.

Desperately needing a successful deployment to modernize the communications infrastructure for its citizens, Mexico is counting on the Atlas 5 rocket to safely launch a new satellite Friday.
