Water On Mars?

If you can see the dark streaks in that picture of Mars, you may be viewing the first possible evidence of there being water on Mars. Scientists suggest that those streaks are caused by the freezing and evaporation of salty water. It is truly fascinating to know that there may be water on Mars because that causes Mars to have a better chance of sustaining life. Scientists believe that calcium chloride has a big part to play in those streaks, they could melt the mixture and evaporate everything but some water. NASA's Spirit and Opportunity found many signs that might also suggest the possibility of there being water, but, NASA's Curiosity rolled by stream beds and recently found this excellent example. This will also be published in the latest issue of Geophysical Research Letters.
