A legacy of smoke and fire is celebrated in the May episode of "Focus on Marshall." The "Focus on Marshall" team traveled to Promontory, Utah, for the final ground test of a space shuttle solid rocket motor in February. The test was conducted to ensure the safe fly-out of the remaining space shuttle missions. A total of 43 design objectives were measured through 258 instrument channels during the two-minute static firing. Hear from Marshall Center managers as they reflect on the historic 52nd and final test conducted for NASA at the ATK Launch Systems' facilities in Promontory. You'll also hear from employees who have worked on the project since the first test was conducted in July 1977.
