SpaceX’s Falcon 9 rocket shattered while traveling at 2,900 mph, about 27 miles up. Everything seemed to be going well until the rocket went supersonic. It’s supposed that the pressure got too high in the liquid-oxygen tank of the rocket’s upper stage. “The teams will work through this. We’ll learn from these events and I think we’ll get stronger from these events,” NASA’s top spaceflight official, William Gerstenmaier said. The private company SpaceX is in charge of the accident investigation. Anyone who finds debris from the rocket explosion was asked to call 321-867-2121 and not to touch such objects on the beach. Other two previously deliveries to the International Space Station (including one launched from Russia) failed.
