[SLS] DM-3, 5 Segment Solid Rocket Booster Motor Test Firing

At the ATK Aerospace Systems test facility in Promontory, Utah a test firing of a 5 segment SRB took place. Derived from the 4 segment Space Shuttle SRB this test will continue to advance understanding of five-segment solid
rocket motor performance and specifically assess performance at the
highest end of the motor's accepted temperature range.
