SpaceX's Starship exploded in a fiery blaze during a routine engine test in Texas – raising questions about what's next for Elon Musk's company.

The huge blast enveloped the craft as it stood upright at Starbase, before massive plumes of flames and smoke mushroomed into the night sky, video footage of the incident late Wednesday showed.

All of SpaceX’s Texas operations — including the explosion during Wednesday’s engine test — take place at the company’s Starbase facility in Boca Chica, a beachside community near Brownsville. The site sits along the Gulf of America, about 20 miles from the U.S.-Mexico border.
