Wary of damaging flight hardware, engineers designingthe Space Launch System static engine fire setconservative parameters that would automaticallycut off the test should sensors detect out-of-limit pressure,temperature or other conditions.Which is exactly what happened at 5:28 p.m. EST onJan. 16 when the booster’s four Aerojet Rocketdyne RS-25engines shut down just 67.2 sec. into a planned 485-sec.burn on the B-2 test stand at NASA’s Stennis Space Centerin Mississippi.
