    Another instrument used to measure disk media is the OptiFLAT substrate tester from ADE Phase Shift. Using white light, the tool measures the front-surface flatness of plane-parallel transparent substrates without coating the rear surface. The OptiFLAT features fully interactive data mapping, bearing-surface analysis, and data manipulation; uploading of statistics to networks; single-pass flatness and microwaviness data gathering; high-resolution CCD camera; and video alignment for tip/tilt and

    NASA’s X-59 quiet supersonic research aircraft sits in its run stall at Lockheed Martin’s Skunk Works facility in Palmdale, California, firing up its engine for the first time. These engine-run tests start at low power and allow the X-59 team to verify the aircraft’s systems are working together while powered by its own engine. The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to solve one of the major barriers to supersonic flight over land by making sonic booms quieter. NASA/Carla Thomas image.
