Before every launch, NASA unleashes an enormous wave of water in just a few seconds — but here’s the twist: it’s not to cool the engines, it’s to quiet the sound. 🚀💦 Rocket engines roar past 180 decibels, loud enough to crack concrete or even damage the spacecraft itself. To handle that, NASA created the Sound Suppression Water System, which floods the launch pad right before ignition. The water absorbs the acoustic shock, turns to steam, and softens the violent vibrations and heat. About six
