Abstract:

A previously flown rocket payload designed to measure atmospheric density in the thermosphere through Rayleigh, backscatter of a dye laser signal, was modified and refurbished. In its earlier field test the payload failed to provide any data, apparently because of a timing problem. Relaunched the laser failed to operate because of a minor component failure. However, measured background intensities were orders of magnitude higher than anticipated. The source of the background signals has not been positively identified since the rocket aspect data have not been finalized. The most likely sourcce appears to be scattering from the earths atmosphere illuminated by the below horizon sun.
