Video: Falcon 9 rocket test-fired at pad 39A (members only)

Investigators believe a leak of propellant inside the Crew Dragon spacecraft’s propulsion system led to the capsule’s explosion April 20 during a ground test at Cape Canaveral, and a senior SpaceX official said Monday that delays are making it “increasingly difficult” to fly astronauts on the commercial spaceship before the end of the year.

United Launch Alliance has released views from cameras mounted aboard the company’s most recent Atlas 5 rocket launch showing the rocket’s blastoff from Cape Canaveral at dawn Aug. 8 with a U.S. Air Force communications satellite.

SpaceX ground teams at Cape Canaveral transferred a Falcon 9 rocket to launch pad 40 and rotated the booster vertical Monday for a preflight hold-down firing, ahead of a liftoff scheduled for Wednesday night carrying 60 satellites into orbit for the company’s planned Starlink broadband constellation.
