The countdown clock hit T-0. Some engines ignited. Steam surrounded the rocket. But SpaceX's massive Starship rocket stayed on the pad.

The much anticipated Thursday, July 16 liftoff from Texas was aborted. While a new launch date has not yet been set, it won't be until next week at the earliest.

"Some of the engines didn't start, triggering an automatic launch abort. Now offloading propellant," SpaceX CEO Elon Musk wrote on X shortly after the abort.

The engine visual on the SpaceX webcast showed four out of the 33 Raptor engines on the Super-Heavy booster did not start up.

Musk later updated that two of the Raptor engines would be replaced out of caution.

This 13th Starship test flight from Starbase, Texas marks the second test overall of the new Starship V3 (Version 3), which is the same model of the ship expected to someday launch from NASA's Kennedy Space Center Pad 39A. Starship will later also launch from Cape Canaveral Space Force Base's Launch Complex 37, where SpaceX is building two launch pads -- 37A and 37B.

SpaceX claims that a debut Florida launch for Starship could come as early as later this year, however that depends on how well the upcoming test flight goes.

When this second test flight of Starship V3 does happen, the goals are: successful launch, controlled booster landing, ship coasting in space, a relight of a single ship engine, deployment of 20 Starlink satellites, and a splashdown of the ship in the Indian Ocean.

Six of the Starlink satellites are outfitted with cameras to assess the ship's heatshield while it coasts in space.

The Super-Heavy booster will not be caught back at the launch site for this mission, as SpaceX is still testing the performance of the engines. It is targeting a controlled splashdown in the Gulf of America, also known as the Gulf of Mexico, after stage separation.
