Come explore the Red Planet, Mars. Even without the aid of telescopes, Mars is easily seen and recognized in the sky by its reddish color. While Earth and Mars have many similarities, there are many drastic differences as well, including no liquid water on Mars’ surface and it having only a very tenuous atmosphere. While in many ways Mars has a less hostile environment than Mercury or Venus, it in no way is life-friendly or characteristic of a world intended for life and should make us appreciate our uniquely designed planet Earth.
