More space news and info at: http://www.coconutsciencelab.com - from the pioneering Viking missions onwards, our knowledge of Mars has been transformed and we now have an extraordinarily detailed picture of the planet.

There are dust storms, polar ice caps and four distinct seasons. Mars has the largest volcanic mountain in our solar system and a canyon stretching over 5,000 kilometers.

More remains to be learned from Mars. Not least, whether the methane results from geological activity, or past or present life.
