WE HAVE LIFTOFF: Massive SpaceX rocket takes flight as Trump watches alongside Elon Musk.

SpaceX’s massive Starship rocket launched for its latest test flight at 5 p.m. ET, where the company didn’t catch its Super Heavy booster after takeoff.

Today’s mission marks SpaceX’s fastest turnaround yet, with new upgrades to the booster’s propulsion systems aiming for a smoother and faster catch using the launchpad’s “Mechazilla” claws.

President-elect Donald Trump attended the event with SpaceX CEO Elon Musk at the company’s Starbase in Boca Chica, Texas.
