On the journey to our neighboring planets contributions have been made by Nikola Tesla, Nazi weapons of war, a Cold War space race, and a collection of discoveries made by NASA robots direct from Mars..

In the future humans may well leave Earth and colonize Mars. Evolutionary biologist, Dr. Scott Solomon foresees a possible series of changes to our species, from the size of our hearts and heads, to the pigments in our skin.
