Development of a light weight narrow field of view (NFOV) multispectral plus hyperspectral imaging system provides the ability to remotely observe hypersonic reentry vehicles. The observations can be used to accurately extract local skin temperature during peak heating, recognize anomalies, and recommend a course of action to avoid catastrophic failure. During boost phase, the spectral measurements can be used to detect the presence of metal contaminants in the exhaust plume. Metallic emission is an indication of component wear and early indication of potential engine failure. In addition to supporting NASA's next generation Space Launch System, the proposed technology could be utilized by the DoD in support of the Reusable Booster System (RBS). In addition, the light weight optical system flown on a UAV could be utilized by MDA for tracking missile enemy missile launches for extreme range to close the fire control loop.
