Live coverage: Delta 2 launches

SpaceX will not be making a Falcon 9 launch attempt Tuesday night. The next opportunities to launch the Falcon 9 with 60 Starlink satellites from pad 39A at the Kennedy Space Center will come at 3:24 a.m. EST (0824 GMT) or 5:42 a.m. EST (0942 GMT) Thursday. This change in launch time suggests SpaceX will target a different orbital plane within the Starlink constellation.

The next-to-last Delta 2 rocket is being stacked at its California launch site to take flight in January to put a civilian weather satellite into polar orbit.

SpaceX test-fired its next Falcon 9 rocket at NASA’s Kennedy Space Center on Saturday in preparation for the company’s 17th launch of the year, a mission tentatively set for liftoff Wednesday with a secretive payload named Zuma for the U.S. government.
