The Planets - Terra Firma

Documentary series tracing our exploration of the solar system. This programme investigates geological activity, looking at the discovery of frozen lava plains on Venus, and a volcano on Mars that would dwarf Mount Everest. Scientists postulated that despite these intriguing surface features, the planets were effectively dead. However, pictures from the moons of Jupiter and Neptune would soon contradict this theory.
