Live coverage: Two telecom satellites launched by Falcon 9, booster recovery fails

A Boeing-built communications satellite lifted off at 7:21 p.m. EDT (2321 GMT) Monday on top of a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. The spacecraft will add to Inmarsat’s Global Xpress network linking airplanes, ships and other mobile terminals with broadband Internet and data services.

SpaceX successfully launched 60 more Starlink internet satellites Monday night from Cape Canaveral, but lost the Falcon 9 rocket’s reusable first stage booster during a landing attempt on a drone ship parked in the Atlantic Ocean.

Climbing away from Earth on the power of its liquid hydrogen-fueled main engine and twin solid rockets, a Delta 4 booster successfully launched a new Global Positioning System satellite Wednesday to benefit U.S. military operations and civilian society as a whole.
