Video: Delta 4 launch highlights

SpaceX has delayed the launch of the SES 12 communications satellite until shortly after midnight Friday at Cape Canaveral, allowing teams additional time to complete pre-launch vehicle checks and wait for improved weather conditions. The launch, which was previously set for Thursday, is expected around 12:29 a.m. EDT (0429 GMT) Friday.

With another SpaceX rocket poised for launch just a few miles away, a Falcon 9 launcher soared through a moonlit sky over Cape Canaveral on Feb. 4 carrying 60 more Starlink internet satellites into orbit.

NASA ground crews at the Kennedy Space Center are continuing to stack segments of the Space Launch System’s side-mounted solid rocket boosters on a mobile launch platform inside the iconic Vehicle Assembly Building.
