White Mars

From its zenith in Lowell s work of the 1890 s, this vision of Mars declined to its nadir after the Mariner 4 flyby in 1965. Mariner 4 showed a cratered, dusty ball clad in only the most diaphanous of atmospheres— one whose white polar regions were declared to be most likely covered in dry ice (carbon dioxide rather than water). As the data from the Viking landers of the 1970 s proved inconclusive and controversial, the vision of dry, white Mars dominated discussion of the planet for decades. 

Krypton is present in the air to the extent of about 1 ppm. The atmosphere of Mars has been found to contain 0.3 ppm of krypton. Solid krypton is a white crystalline substance with a face-centered cubic structure which is common to all the "rare gases."...
