'Strongest' evidence yet of water on Mars

NASA's Opportunity rover has discovered Gypsum on Mars, a material formed by water flowing through rock.
Revealed at the American Geophysical Union conference in San Francisco this week, the discovery provides the most convincing evidence ever for liquid water on Mars. "This is the single most bullet-proof observation that I can think of that we've made this entire mission," said planetary scientist Steve Squyres. The Opportunity rover has been trundling around on the surface since 2006, defying all expectations for its life expectancy long after its twin, Spirit, got stuck in 2009.
The rover, called Opportunity, and its twin, Spirit, arrived on opposite sides of Mars in January 2004. Over the years, the rovers, aided by several orbiting spacecraft, have returned a convincing body of evidence that Mars was not always as cold and dry as it is today.

I hope the water on Mars doesn't contain all the crappy chemicals that earth water has.

Well, as we all know, water is present on Mars in its crystal form - ice. But in liquid form? Yes, that's another thing.

Would the asteroid strike in this article have caused enough mass to leave mars entirely thus leaving not enough mass to hold an atmosphere as thick as ours. Then the solar winds blew off the water over time back in to space? http://www.scientificamerican.com/article.cfm?id=giant-asteroid-flattened

NASA is suspecting that there is water on the Mars. http://science.nasa.gov/science-news/science-at-nasa/2011/04aug_marsflows/
