Video: Falcon 9 test-fired before space station cargo launch (members only)

SpaceX’s third Falcon Heavy rocket took off from the Kennedy Space Center in a predawn launch Tuesday, delivering two dozen research and weather observation spacecraft into orbit on a marathon three-and-a-half mission for the U.S. Air Force. The mission included the successful landing of the Falcon Heavy’s two side boosters back at Cape Canaveral, and a SpaceX recovery boat netted part of the rocket’s payload fairing for the first time.

A United Launch Alliance Atlas 5 rocket took off from Cape Canaveral on Aug. 8 with the U.S. Air Force’s fifth Advanced Extremely High Frequency communications satellite, the second launch from Florida’s Coast in a span of less than 35 hours.

A new variant of India’s workhorse Polar Satellite Launch Vehicle with two strap-on solid rocket boosters and an upper stage converted into an experiment-carrying platform debuted Thursday with a launch into polar orbit.
