Worlds of the Solar System
Mars

The Red Planet. Mars has held our curiosity as a species for a very long time. Percival Lowell's 1895 book on Mars, where he proposed canals were being used by intelligent aliens to move water on a drying world, led directly to H.G. Wells' "War of the Worlds" and the beginning of alien scifi. Now we want to know more about the 4th rock from the Sun. What was Mars like in the distant past? How has Mars changed over time? Was there ever life, or is there still life, on the Red Planet? Will humans one day populate the surface of Mars?
