Non-Stellar Celestial Backgrounds.

Abstract

Part 1 - The spectral emissivity of several lunar surface features as measured during two balloon flights are reported. The wavelength of the peak emissivity is found to differ among the surface features investigated. After the two flights reported the spectrometer utilized for the lunar measurements was converted to an absolute filter radiometer with a 15 arc second field of view for martian radiance measurements. The modifications are described. Part 2 - The effects of solar wind protons on the lunar surface were simulated with a low-energy ion beam accelerator installed on a differentially-pumped, ultra high vacuum system. (Author)
