The Falcon 9 rocket will take flight from Launch Complex 40, carrying a batch of 21 Starlink internet satellites into low-Earth orbit. Backup launch opportunities are available until 6:24 a.

Last year, the company launched more than 130 Falcon 9 flights, about two-thirds of them devoted to building out the Starlink network, the biggest satellite constellation ever assembled. SpaceX currently operates nearly 7,000 Starlink satellites in LEO, according to astrophysicist and satellite tracker Jonathan McDowell.

Who's up for a late-night launch? Weather permitting, a SpaceX Falcon 9 rocket should be visible from the Treasure and Space Coasts after liftoff.
