Seven weeks after an explosion sent pieces of SpaceX's Starship launch vehicle falling into the Atlantic, the company is trying again this evening. The more than 400-foot Starship, powered by 33 Raptor engines, is scheduled for launch no earlier than 6:30 p.m. ET from SpaceX's launchpad at its Starbase facility near Brownsville, Texas.

SpaceX officials said they conducted an "extended duration static fire" with the Starship they intend to use for its eighth test flight. They said they used multiple engine thrust levels and hardware configurations to recreate the vibration levels from the failed flight.
