Video: Falcon 9 stands at the launch pad

After back-to-back launches last weekend, SpaceX could launch its next Falcon 9 mission as soon as Sunday from NASA’s Kennedy Space Center in Florida with a high-power Intelsat communications satellite.

Launch startup Relativity Space has won approval from the U.S. Air Force to take over a disused launch pad at Cape Canaveral for the company’s methane-fueled Terran 1 rocket, a 3D-printed launcher that could carry small satellites into orbit by the end of 2020.

These photos show the fiery liftoff of a United Launch Alliance Delta 4-Heavy rocket from Cape Canaveral on Dec. 10, riding three pillars of flame from its hydrogen-fueled RS-68A main engines.
