ATK Thiokol (Edina, MN) manufactures everything from bullets to the reusable solid rocket motors (RSRM) that have launched every space shuttle since the program's maiden flight in 1981.
To ensure that each RSRM functions perfectly, flight after flight, the company pays close attention to its processes throughout initial production, postflight inspection, transportation, storage and reassembly. This includes weight-checking the equipment used to handle the rocket's many reusable components.
