Live coverage: Delta 2 launches

SpaceX completed another another launch to add to the company’s Starlink broadband network Thursday. A Falcon 9 rocket lifted off at 8:46 a.m. EDT (1246 GMT) Thursday from pad 39A at NASA’s Kennedy Space Center in Florida.

Two weeks after a sensor problem forced a delay, an Ariane 5 rocket blasted off at 6:04 p.m. EDT (2204 GMT) Saturday from French Guiana with two commercial communications satellites to cover the United States and Japan, and a Northrop Grumman-built robotic satellite servicing mission designed to link up with another spacecraft in geostationary orbit.

The nation’s existing Atlas and Delta launch sites are vying for a future when United Launch Alliance completes its modernization with a new rocket system and downsizing to one pad on each coast.
