Water on Moon for sure

NASA came with a news that may be of interest for biologists. Scientists have long speculated about the source of vast quantities of hydrogen that have been observed at the lunar poles. The LCROSS findings are shedding new light on the question of water, which could be more widespread and in greater quantity than previously suspected, says the article.

Water could only exist in areas of permanent shadow and those areas exist at the lunar poles. Some of these crater floors have not seen sunlight for possibly billions of years. Temperatures within these crates do not go above –280° F (-173° C) so they act as ‘cold traps’ where even light elements or compounds don’t have enough energy to evaporate.

"We are ecstatic," said Anthony Colaprete, LCROSS project scientist and principal investigator at NASA's Ames Research Center in Moffett Field, Calif. "Multiple lines of evidence show water was present in both the high angle vapor plume and the ejecta curtain created by the LCROSS Centaur impact. The concentration and distribution of water and other substances requires further analysis, but it is safe to say Cabeus (moon crater) holds water."

Also on Mars are water. Phoenix Mars Lander have identified water in a soil sample.

Man is greedy as usual. Now we can live on the Moon!

Just like on Earth, water will be a crucial resource on the moon, says article search for water. Transporting water and other goods from Earth to the moon’s surface is expensive. Finding natural resources, such as water ice, on the moon could help expedite lunar exploration. With charts of hydrogen findings.
