Not many would know that a new rocket launch might require so much water.
NASA tested the water deluge system as part of the preparations for its new Space Launch System. These preparations also include shooting 450,000 gallons of water on to the launch pad at the Kennedy Space Center.
NASA posted this video of the 15th October test to YouTube on Friday.
According to the space association, the water deluge system is used to reduce the extreme heat and energy that is generated after a rocket launch.
The Space Launch System is basically a huge rocket which NASA will use in a series of missions traveling to the moon and the planet Mars.
NASA said that the system is designed to carry larger payloads and generate more energy which could open the door to deep space missions including robotic scientific missions to planets like Mars, Jupiter and Saturn.
