SpaceX scrubs Falcon 9 rocket launch

CAPE CANAVERAL, Fla. —

SpaceX has scrubbed the launch of a Falcon 9 rocket from Cape Canaveral Air Force Station.

The two-hour launch window opened at 5:40 p.m. Thursday, but then the launch time was adjusted to 7:36 p.m. for an unknown reason.

SpaceX then tweeted that the launch was scrubbed out of an abundance of caution.
