A SpaceX Falcon 9 rocket sporting 88 small satellites blasted off from Florida Wednesday, flew over cuba and climbed into polar orbit while the primary level, making its 8th flight, flew itself lower back to a photo-best Cape Canaveral touchdown. Heralded by means of dual sonic booms, the well-traveled first level, charred and sooty from re-entry heating, touched down about 8-and-a-1/2 mins after liftoff, chalking up spacex's 89th successful booster recuperation and its twentieth at the Cape Canaveral Space Force Station.
