A SpaceX rocket exploded on Sunday after breaking a support leg while landing on a barge in the Pacific Ocean. The rocket successfully delivered a U.S.-European ocean-monitoring satellite into orbit, but failed to land upright on a floating platform and caused a fiery explosion. SpaceX CEO Elon Musk posted a video of the landing on Instagram, showing the rocket toppling over and exploding. “Root cause may have been ice buildup due to condensation from heavy fog at liftoff,” Musk said in his post.
