Introduction
When we ask "Where might we find extraterrestrial life", the first place many scientists turn to, because of its similarity to the Earth, is Mars. Mars may have been like the Earth in its past. Although no signs of life on Mars have been found, scientists will continue to search because they are aware of the potential for life in extreme environments.
