Is there life on Mars? We begin with a brief historical survey of the

idea of inhabitable Mars, from Herschel to Lowell, and look at how the

idea of Mars and Martians is deeply embedded in the popular culture.

We then turn to spacecraft explorations of Mars, and how they have changed

our view of the Red planet. We will discuss the on-going search of Martian

life, past and present, particularly the Viking 1 and 2 experiments, the

Allan Hills Meteorite controversy, Mars Methane, and recent important

results from the Phoenix lander. We'll end by briefly noting future

directions in Mars exploration.
