Riding atop a fuel cell filled with a million pounds of liquid kerosene, SpaceX launched 21 Starlink communications satellites on a Falcon 9 rocket from Vandenberg Space Force Base in California at 6:45 p.

SpaceX is gearing up for its next Falcon 9 rocket launch scheduled for early Wednesday morning. The launch, part of its ongoing Starlink mission, is set to deploy several Starlink V2 Mini satellites into low Earth orbit.

SpaceX has scrubbed their Wednesday afternoon launch attempt of a Starlink mission. Now, 21 satellites are expected to head to low-Earth orbit tomorrow morning.
