Invaders of Mars

Explore the Martian surface as seen by Earth's "invaders" – various spacecraft that have visited the red planet since Viking 1 first landed there in 1976. Fly over great chasms, canyons and volcanoes, land on an icy polar cap, and watch amazing dust devils swirling over the surface of Mars – winds that can ultimately trigger a thunderstorm massive enough to cover the whole planet! Show includes a musical roller coaster ride over the surface of Mars!
