Video: Falcon 9 rocket fires up engines on launch pad (members only)

Boeing and NASA officials said Thursday the first launch of astronauts on Boeing’s delay-prone Starliner crew capsule won’t happen in July after engineers recently discovered a problem with the spacecraft’s parachute system and identified flammable tape around wiring harnesses inside the vehicle.

SpaceX hopes to launch Falcon 9 rockets from its two launch pads in Florida and its one in California on Saturday night. Liftoff of the Eutelsat 36D satellite from NASA’s Kennedy Space Center happened at 5:52 p.m. EDT (2152 UTC), the opening of a nearly four-hour window.

NASA and SpaceX have delayed the launch of the Crew Dragon “Resilience” spacecraft from the Kennedy Space Center until 7:27 p.m. EST Sunday (0027 GMT Monday) to wait for improved downrange weather and sea conditions, and better onshore winds at the launch site.
