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. But the soggy weather forecast looks awful: The Space Force’s 45th Weather Squadron only predicts a paltry 20% chance of “go for launch” weather, citing cumulus clouds, lightning and surface electric fields.

Regardless, SpaceX is targeting a two-hour launch window that opens at 5:12 p.m. to launch the Falcon 9 rocket 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.

Check back for live FLORIDA TODAY Space Team launch coverage updates on this page, starting about 90 minutes before the afternoon launch window opens. When SpaceX’s live webcast begins about 15 minutes before liftoff, we’ll post it below next to our countdown clock.
