Live coverage: Delta 2 launches

Meteorologists predict mostly sunny skies, mild temperatures and light winds Sunday for the launch of a SpaceX Falcon 9 rocket from California’s Central Coast with a $364 million oceanography satellite for U.S. and European science institutions.

An Ariane 5 rocket launched Tuesday with the Arabsat 6B and GSAT 15 communications satellites to broadcast television across the Middle East, North Africa and Central Asia and link India with telecom and navigation services. Liftoff from Kourou, French Guiana, occurred at 2134 GMT (4:34 p.m. EST).

The U.S. Space Force is planning for an airborne launch of a solid-fueled Pegasus rocket over the Pacific Ocean by early summer after quietly awarding Northrop Grumman a contract for the mission last year.
