SpaceX CEO Elon Musk suggested on X that a high-pressure nitrogen tank failure was behind the explosion of the company's massive Starship rocket.

A SpaceX heavy-lift Starship launch vehicle exploded late Wednesday during a pre-flight test at Starbase in Texas.

The Starship experienced a “major anomaly” before starting its 10th flight test. Elon Musk’s giant moon and Mars rocket has a mixed record of success.
