I recently discovered Martian Soil, a neat site, and one that seems to be updated quite regularly. In their own words:
Martian Soil is a daily blog dedicated to Mars, bringing the exploration of the Red Planet closer to enthusiasts and little green men alike.
Within the next two weeks, Mars will make its closest approach to Earth in almost 60 thousand years, according to this BBC report. As the red planet draws ever closer to earth the Martian Soil site takes on increased relevance, providing news and insights into what has long been one of the most intriguing planets in our solar system.
