ATK and NASA will be conducting a static fire test of one Solid Rocket Booster (SRB), known as FSM-14 (Flight Support Motor), Thursday.
The always-spectacular test will fire over 15 million horsepower up a hillside at ATK’s test facility in Utah, in order to provide performance data on replacement insulation materials for the shuttle’s remaining flights, and test data for the first stage of the Ares I Crew Launch Vehicle.
