Horizon - Season 12 - Eps 6: The Planets
By the end of 1974, Mars, Venus, Mercury and Jupiter had all been visited by spacecraft.

Tonight's programme shows how these geological features give clues to the way the planets evolved; how they have helped scientists in their attempt to reach back 5,000 million years to understand the formation of the solar system itself.
