Morton Thiokol Space Operations will dedicate a fully automated, robotic plant that washes mixing bowls used in casting rocket fuel Wednesday.

The building, at Thiokol's Wasatch Operations facility 23 miles west of Brigham City, is designed to clean the bowls used in propellant casting, or shaping, for shuttle solid rocket motors.Dedicating the new facility signifies the aerospace firm's first step toward a totally automated plant using robots in casting of rocket fuel, said Tim Carter, Space Production director.

After dispensing a 7,000-pound load of propellant, each mixing bowl is taken to a special cleaning area.

An automatic guided vehicle travels along a signal path wire, located in the floor of the 10,000 square-foot building, to a bowl inverter which grasps and rotates the bowl on its side.
