Curiosity rover finds more evidence of water on Mars

On September 18th, the Curiosity rover, first touching down on Mars last August, found significant evidence that water once existed on Mars, and the habitat at that time could have supported microbial life. Curiosity first found mudstone, a rock containing clay that is made of fine minerals that settle slowly, usually caused by water and wind.

The rover also found small sulfate veins on the surface that suggests a flow of water transported these sulfate-rich minerals to these veins from their original location. This process is very common in ancient rivers on Earth, so scientists believe these veins are a result of rivers on Mars’ surface millions to billions of years ago.
