No injuries were reported.
A three-engine version of the company's reusable Falcon 9 rocket was being tested when an "anomaly" was detected and the rocket self-destructed. SpaceX said the equipment was trained to do that when an anomaly is detected.
Several grass fires were started by falling debris, but it all remained within the designated testing area and none of the fires were serious.
SpaceX founder Elon Musk addressed the incident on Twitter, clarifying there were no injuries and calling rockets "tricky."
