@stupidastro.92: NASA pumps large volumes of water during rocket launches and engine tests to protect the rocket and launchpad from the extreme heat and sound waves produced by the engines. This system, called the Ignition Overpressure Protection and Sound Suppression (IOP/SS) water deluge system, helps dissipate thermal energy, reflects and absorbs acoustic energy to prevent damaging vibrations, and can suppress fires. #space #scientist #earth #nasa #physics
