PROMONTORY - July 16, 2022
On Thursday, July 21, Northrop Grumman Corporation will conduct a full-scale static test of NASA’s Space Launch System (SLS) solid rocket motor at Northrop Grumman’s Promontory test facility. The firing will take place between 10 a.m. and 2 p.m.
The SLS’s twin, five-segment rocket motors, are the largest, most powerful boosters ever built for flight and contribute more than 75 percent of the SLS rocket’s initial thrust at launch. SLS is the backbone of Artemis lunar exploration. Northrop Grumman is the lead contractor for the SLS solid rocket boosters.
This hot fire test will demonstrate a newly qualified motor initiation system and qualify a new nozzle phenolic ablative solvent material. The booster will be fired during the demonstration, called the Flight Support Booster 2 test, to evaluate materials and make improvements for future Artemis missions, and will provide early learning for the next generation Booster Obsolescence and Life Extension booster.
