Meteorites give clues to Mars water

2012-06-22 12:30

Washington - The possibility that Mars once sustained life has been supported by an analysis of two meteorites that show the Martian water supply was far larger than previously thought, the Carnegie Instution of Science announced.

The two meteorites were ejected from Mars 2.5 million years ago, still young by meteorite standards, and the minerals within them contain water levels similar to that of the Earth's mantle.

Analysis of the meteorites suggest that water was incorporated into the surface of Mars when it was created, scientists said, and stored underground when the different elements and minerals within the mantle separated.

"There has been substantial evidence for the presence of liquid water at the Martian surface for some time," said Erik Hauri of the Carnegie Institution.

"So it's been puzzling why previous estimates for the planet's interior have been so dry. This new research makes sense and suggests that volcanoes may have been the primary vehicle for getting water to the surface."

      Yes, the same science fiction that allows you to type your message on your computer and send your message for all the world to see. Twit!!

    I can't understand how liquid water can exist on Mars surface. Mars atmosphere is so thin than it will boil away immediately. It is thinner that most people think. If I remembered correctly it is between 6 and 7 mb, whereby Earth atmospheric density is 1014 mb.(At sea level)

      I just read 2 words in this article which may prove why you don't understand. They are "stored underground" Didn't Mars have an atmosphere a couple of million years ago? Right now it doesn't have the atmospheric pressure to maintain water [on the surface] in liquid form. Water FROZEN around the poles are still there, and so may water under the mantle (either frozen or liquid).
