Description:
Multispectral images of the basaltic surface of Venus obtained by Venera 13 were processed to remove the effects of orange-colored incident radiation resulting from interactions with the thick Venusian atmosphere. At visible wavelengths the surface of Venus appears dark and without significant color. High-temperature laboratory reflectance spectra of basaltic materials indicate that these results are consistent with mineral assemblages bearing either ferric or ferrous iron. A high reflectance in the near-infrared region observed at neighboring Venera 9 and 10 sites, however, suggests that the basaltic surface material contains ferric minerals and thus may be relatively oxidized.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pieters, C M -- Head, J W -- Pratt, S -- Patterson, W -- Garvin, J -- Barsukov, V L -- Basilevsky, A T -- Khodakovsky, I L -- Selivanov, A S -- Panfilov, A S -- Gektin, Y M -- Narayeva, Y M -- New York, N.Y. -- Science. 1986 Dec 12;234(4782):1379-83.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17755059" target="_blank"〉PubMed〈/a〉
