Once there were widely debated Martian spiders and dark spots, now we have further evidence of dry ice sublimated under warming southern atmosphere in Mars' south polar cap. Numerous of plumes showed the carbon dioxide evaporing and carrying particles from image of Mars Reconnaissance Orbiter spewing into the sky, which is in favor of abiotic nature of the Mars southern phenomenon in spring time, rather than biotic origin that was speculated by some investigators few years ago.
