No signature of clear C[O.sub.2] ice from the 'cryptic' regions in Mars' south seasonal polar cap
Article Abstract:
The near-infrared imaging spectroscopy of the south seasonal polar cap of Mars is reported. The models of the spectra have indicated that the low albedo results from extensive dust contamination close to the surface of a C[O.sub.2] ice layer and the strength of the C[O.sub.2] absorption increases after mid-spring, so that part of the dust is either carried away or buried more deeply in the ice layer during the C[O.sub.2] ice sublimation process.

Early geochemical environment of Mars as determined from thermodynamics of phyllosilicates
Article Abstract:
The investigation of the geochemical conditions prevailing on the surface of Mars during the Noachian period by employing aqueous equilibria of phyllosilicates reveal that the absence of Noachian carbonates might be due to the low levels of atmospheric carbon dioxide.

Cinderella science
Article Abstract:
The increasing amount of carbon dioxide in the atmosphere was detected by Charles David Keeling. The need for substantial funding for carrying out extensive research on environment is stressed.
