Mars - The Red Planet
"In more than one respect, the exlporing of the Solar System and homesteading other worlds constitutes the beginning, much more than the end, of history" -- Carl Sagan

Of all the planets in the solar system, Mars has sparked the greatest human interest. The conditions in Mars are believed to be hospitable since the planet is similar to Earth in many ways. For ages, humans have been speculating about life on Mars. However, the question that is to be still answered is whether Mars has a biosphere or ever had an environment in which life could have evolved and sustained.
