    • During the Mariner 7 flyby of Mars, the infrared spectrometer recorded distinct, sharp absorption. near 3020 and 3300 reciprocal centimeters between 61�S and 80�S. at the edge of the southern polar cap, with maximum optical density near 68�S and 341�E. These hands, which match in frequency the v3 bands of methane and ammonia, can be associated with previously unreported spectral features of solid carbon dioxide exceeding 1 millimeter in thickness. Possible reasons for the geographic… CONTINUE READING
