Surface water on Mars?

I know very little about this subject, however I find the prospect on water on Mars to be very interesting.

Re: Surface water on Mars?

The evidence is pretty clear that water did flow on Mars at some time in the past. However, it is far from clear whether it still does. The observations mentioned in the article could be explained in a number of ways, most of which do not involve current surface water on Mars. All of NASA's Mars missions are designed to search for clues to water on Mars.

Re: Surface water on Mars?

Stand by, I expect there will be an announcement today or tomorrow about water on Mars. It is a big deal if we are ever to live there. Also interesting would be to find out why once plentiful water has mostly disappeared. Mars is a very hostile envirenment to life as we know it; it is cold (-70), dry, not much atsmophere and that has methane and a lot of hydrogen peroxide in the ground. Still better prospect than the other planets.

Re: Surface water on Mars?

I saw the NASA announcement at noon (CST) today. These guys have observational evidence of water flows during MGS's mission span (1999-2006, sad to say it seems forever kaput as of November). They showed two places where new features (light, waterflow-shaped deposits) appeared in craters and spoke of why it's significant and why they think it might be water. They had before and after images taken by MGS (Mars Global Surveyor) where the apparent water-created features happened between the photos.

I expect a lot of news stories shortly, and if it's as significant as they think it is the newly arrived orbiter (MRO) will probably make these sites an early priority and rover missions may be planned around the areas.

These guys really think liquid water flows can be found today on Mars. Not constant rivers, but some sort of groundsprung water be it aquifers or some sort of melting mass.

EDIT: They also have images of new craters forming between imaging sessions, so there are some fresh crater sites to check out, too. They apparently hadn't anticipated that they might catch before and after shots of current events and are excited that they have.
