Last week NASA’s MAVEN probe began orbiting Mars in an effort to measure and map the Martian atmosphere. Today, Mars, known as the red planet, is bone dry and it’s atmosphere is being broken down by the sun’s solar winds, but evidence shows that it was once much more like Earth. From liquid channels to lake beds, there is clear evidence that Mars once had water as well as a magnetic field. So what happened to this water?
