Researchers calculate size of particles in Martian clouds of CO2 snow

Mars’ carbon dioxide ‘snowflakes’ are about the size of red blood cells. In the dead of a Martian winter, clouds of snow blanket the Red Planet’s poles — but unlike our water-based snow, the particles on Mars are frozen crystals of carbon dioxide. Most of the Martian atmosphere is composed of carbon dioxide, and in the…

Mars has dramatic carbon dioxide atmospheric shifts

Of note: “Unlike Earth, which has a thick, moist atmosphere that produces a strong greenhouse effect, Mars’ atmosphere is too thin and dry to produce as strong a greenhouse effect as Earth’s, even when you double its carbon-dioxide content.” NASA Orbiter Reveals Big Changes in Mars’ Atmosphere PASADENA, Calif. — NASA’s Mars Reconnaissance Orbiter has…
