Capturing SLS

NASA’s recent full-scale ground test of their Space Launch System (SLS) rocket was notable for more than just the engine. It was an opportunity to use a new high dynamic range, high speed camera prototype,

HiDyRS-X, to capture the rocket’s exhaust in detail never seen before. Usually the extreme brightness of the rocket exhaust makes it impossible to see any structure in the flow without completely obscuring the ground equipment. With this camera, however, engineers can see how the engine, exhaust, and surroundings all interact. Be sure to check out the full video. I particularly like watching how the rocket’s exhaust entrains dust and sand from the ground nearby.  (Image credit: NASA, source; submitted by Chris P. and Matt S.)
