Abstract

The Venus Express mission has shown that orbital observations through transparent windows in the CO2 atmosphere of Venus near 1 μm can produce viable data of the surface below. The resultant six windows coincidentally lie in a spectral region where visible-near infrared (VNIR) features of both Fe2+ and Fe3+ occur. Here, we report on laboratory data acquired from a range of well-characterized Venus-candidate rocks and minerals. We discuss how emissivity differences may be interpreted to derive information about rock type, mineralogy, and oxidation state.
