Live coverage: Atlas 5 blasts off with Navy satellite

A European re-entry demonstrator launched aboard a solid-fueled Vega rocket at 1340 GMT (8:40 a.m. EST) from French Guiana, kicking off a whirlwind 102-minute around-the-world test flight to validate technologies that could be used on future reusable launchers and spaceships.

United Launch Alliance teams mounted a top secret payload for the National Reconnaissance Office on top of an Atlas 5 rocket Monday at Cape Canaveral in preparation for a liftoff scheduled just after sunset Nov. 3.

The United Launch Alliance Atlas 5 rocket lifted off from California at 10:30 a.m. local time (1:30 p.m. EST; 1830 GMT) today to deliver the sharp-eyed WorldView 4 satellite into space to collect best-in-the-industry, 31-centimeter-resolution commercial imagery for retail.
