Wide Angle: Mars Roving

The robotic Mars Exploration Rover Spirit is stuck in the Martian soil, but is this the end of the line?

Mars is a rocky, cold and dusty world with a very thin atmosphere composed mainly of carbon dioxide -- it is far from being a cozy place for humans to live and it's not exactly an easy landscape for rovers to keep their traction. However, when compared with our other inner-Solar System options, the Red Planet is our best bet for interplanetary colonization and robotic exploration.

Ahead of any future manned mission to the Red Planet, we need to learn more about the Martian landscape, radiation, water, and we need to answer the big question: Is there any sign of extraterrestrial life in the dirt?

In this Wide Angle, we'll explore the science, technology and history of Mars roving, proving that robots with wheels are superb scouts for mankind before we set foot onto the Martian surface.
