SpaceX's massive Starship spacecraft exploded into a dramatic fireball during testing in Texas late on Wednesday, the latest in a series of setbacks for billionaire Elon Musk’s Mars rocket program.

A SpaceX Starship prototype, Ship 36, was destroyed in a fiery explosion during engine test preparations at Starbase. The incident, which occurred while loading liquid oxygen and methane, halted launch plans for the tenth orbital flight.
