Water Ice On Mars

Digital Hobo — Mon, 23 Jun 2008 06:24:00 GMT

Phoenix Discovered Ice on Mars - Scientists with the Phoenix Mars mission stated yesterday that there certainly is ice on the Red Planet, reporting that their robot digging tool has dug up portions of the white stuff. The spacecraft revealed bright white fragments at the base of a trench while excavating near Mars’ north pole, last Sunday.

Photos of the same sight sent back on Thursday showed the white fragments disappeared convincing scientists that the act was proof of ice that vaporized due to sun exposure. Or, as science men like to explain, the pieces of ice evaporated into the dry atmosphere of the planet thru a process called sublimation.
To decide whether the Martian polar environment could be hospitable, experts are using the shuttle’s equipment to examine minerals in the soil and ice for clues of carbonates and sulphates, which are formed by the action of liquid water.

Evidence of water failed to be produced by the initial results coming from an experiment that baked a soil sample in one of Phoenix's test ovens. A data loss on the module this week stopped scientists from receiving the results immediately after the last testing phase.

Water is a essential for life, but it's just part of the equation. Scientists generally agree that organic carbon and an energy source such as the sun are also considered necessary ingredients.
Mars today is dry and dusty, relentlessly bombarded by radiation and with no noticeable trace of H2O on its surface. But carvings of channels and couloirs on the Martian surface indicate a history involving water. Some scientists hypothesize that water may have evaporated into the atmosphere and the rest was trapped under the surface in the form of ice.

The first evidence of water on the Red Planet was found in 2002 by the Odyssey orbiter, which revealed proof of a frozen water reservoir located near the planet's poles.
