Watch as NASA releases 450000 gallons of water in one minute

NASA's remarkable water system is making a splash all over the internet - as shown in the incredible video above, uploaded to YouTube by the space agency on Friday. It's called the Ignition Overpressure Protection and Sound Suppression system, and NASA uses it to keep the launch pad at a manageable temperature even as its being blasted by a rocket.

Who knew rocket launches might require so much water?

Footage of the feat has gone viral as the space agency's pressure jets fire the water 100 feet (30m) up in the air. Recently released video of one of the tests, conducted on October 15, shows the dramatic action.

Space Launch System, or SLS, is a launch vehicle that Nasa hopes will take its astronauts back to the moon and beyond. It is expected to launch in June 2020. According to Popular Science, its engines and boosters will produce 8.4 million pounds of thrust. Here's where the IOP/SS comes in.

During the launch of Exploration Mission-1 and subsequent missions, this water deluge system will release about 450,000 gallons of water across the mobile launcher and Flame Deflector to reduce the extreme heat and energy generated by the rocket during ignition and liftoff.

The maiden launch will send NASA's Orion capsule on a three-week trek around the moon - an uncrewed test flight known as Exploration Mission-1 (EM-1).

NASA posted a video of the October 15 test to YouTube on Friday.

In less than two minutes from start to finish, the system spews hundreds of thousands of gallons of water into the sky, with the stream climbing to roughly 100 feet into the air like a massive geyser.

"A geyser occurred because the mobile launcher was not present at the pad", explained pad deputy project manager Nick Moss.
