Live coverage: Delta 2 launches

United Launch Alliance, a union of Atlas and Delta rockets formed a decade ago for U.S. government spacelift needs, will conduct its 25th deployment mission for the country’s spy satellite agency Thursday night.

SpaceX has launched its fourth Falcon 9 rocket from Florida’s Space Coast in less than 16 days. A Falcon 9 rocket blasted off with 60 more Starlink internet satellites at 2:42 a.m. EDT (0642 GMT) Sunday. The reusable booster, making its 10th flight, landed on a drone ship parked in the Atlantic Ocean.

The step-by-step stacking of United Launch Alliance’s final Delta 2 rocket was completed in June at Vandenberg Air Force Base in California for liftoff Sept. 15 with an Earth science satellite for NASA.
