SpaceX's much-hyped high-altitude test flight of Starship -- a spacecraft designed to take people and cargo to the moon and Mars -- ended in a fireball as it crash-landed Wednesday in South Texas.

Video shows the large reusable capsule, which is supposed to land vertically, came down way too hard and instantly exploded. However, even though the footage is crazy ... it was not unexpected.

Musk predicted Starship would likely crash land, but said data gathered in the test flight would be critical in moving the mission forward. SpaceX stated ... "With a test such as this, success is not measured by completion of specific objectives but rather how much we can learn."
