February 25, 2010 — The thunderous roar from a space shuttle solid rocket booster reverberating and rebounding off the mountains of northern Utah was heard for the final time Thursday, as NASA and Alliant Techsystems (ATK) ignited their last ground test after three decades of static firings.

The 52nd reusable solid rocket motor (RSRM) ground test since the first was fired July 18, 1977, the two minute and three second horizontal "launch" was performed in support of NASA's remaining four shuttle missions before the fleet is retired later this year.
