purpose of using molecular sieves

Molecular sieve adsorbents are crystalline alumino-silicates, known as zeolites. Their unique structure allows the water of crystallization to be removed, leaving a porous crystalline structure. Laughing Embarassed

Life in Mars

I'm not a scientist by no means, but I think there a 100% chance of life under the surface Mars whether in a cave or deeper under ground where there would be sort of an atmosphere caused by the wight of the surface soil compressing on the underlining soil. Also could be possible for a typ of exoskeleton life form to exist, where as its exoskeleton would act as sort of a pressure suit.

New paper - possible evolution of life on Mars without water

Interesting new paper showing how life could have continued to evolve on Mars in niches without much if any water.

http://online.liebertpub.com/doi/pdf/10.1089/ast.2015.1380

"The evolution of habitable conditions on Mars is often tied to the existence of aquatic habitats and largely constrained to the first billion years of the planet. Here, we propose an alternate, lasting evolutionary trajectory that assumes the colonization of land habitats before the end of the Hesperian period (ca. 3 billion years ago) at a pace similar to life on Earth. Based on the ecological adaptations to increasing dryness observed in dryland ecosystems on Earth, we reconstruct the most likely sequence of events leading to a late extinction of land communities on Mars. We propose a trend of ecological change with increasing dryness from widespread edaphic communities to localized lithic communities and finally to communities exclusively found in hygroscopic sub- strates, reflecting the need for organisms to maximize access to atmospheric sources of water. If our thought process is correct, it implies the possibility of life on Mars until relatively recent times, perhaps even the present."

Mars Water Planet

Olympus Mons looks like a mountain of ice fed by a underground heat source ,depositing
Higher and higher layers and flooding a massive area healing all the damage on the
Surface .Mars could have been a water planet with a sea 200 miles deep
