You don't see this angle of the Space Launch System (SLS) Mobile Launcher (ML) very often -- looking skyward at the tower through the flame hole. The water nozzles pictured in the corners will be used for sound suppression during launch. The purpose of dampening the acoustics with water is to reduce damage to the pad surface, ML, and SLS that is caused by the vibration of the solid rocket boosters and liquid core stage engines.
