Launch recap: Scroll down to review live updates from the Tuesday, July 22, liftoff of a SpaceX Falcon 9 rocket from Cape Canaveral on an SES O3b mPOWER satellite mission. Original story: Monday afternoon, SpaceX's Falcon 9 rocket launch countdown clock ticked all the way down to just 11 seconds remaining — but crews abruptly scrubbed the liftoff attempt. So today, SpaceX will try again to launch a pair of SES O3b mPOWER satellites into medium-Earth orbit. Welcome to FLORIDA TODAY Space Team live coverage of today's mission from Cape Canaveral Space Force Station. SpaceX is targeting 5:12 p.m. to launch the Falcon 9 from Launch Complex 40 at Cape Canaveral Space Force Station. No Brevard County sonic booms are expected. After soaring skyward due east, the rocket's first-stage booster will target landing aboard a SpaceX drone ship out at sea 8½ minutes after liftoff. The Space Force's 45th Weather Squadron only predicted a paltry 20% chance of "go for launch" weather, citing cumulus clouds, lightning and surface electric fields — but stormy weather has steered clear of the Cape this afternoon.
