Thiokol was concerned with rockets.
Thiokol ( variously Thiokol Chemical Corporation , Morton-Thiokol Inc. , Cordant Technologies Inc. , Thiokol Propulsion , AIC Group , ATK Thiokol ; finally ATK Launch Systems Group before becoming part of Orbital ATK ) was an American corporation concerned initially with rubber and related chemicals , and later with rocket and missile propulsion systems . When scientists at the Jet Propulsion Laboratory discovered that Thiokol 's polymers made ideal binders for solid rocket fuels , Thiokol moved into the new field , opening laboratories at Elkton , Maryland , and later production facilities at Elkton and at Redstone Arsenal in Huntsville , Alabama . In the mid-1950s the company bought extensive lands in Utah for its rocket test range , and in 1986 was found at fault for the destruction of the Space Shuttle Challenger and the deaths of its astronauts . Thiokol continues to have major operations in the state , at Magna and Promontory ( manufacture of the Space Shuttle 's solid rocket motors ) , and its current headquarters at Brigham City .
