Rockets to the Planet

Overview

Spacecraft have already been to the nearest planets, Mars and Venus. Within the next 10 years other probes will explore much further, heading inward to Mercury, and outward beyond Jupiter-perhaps even to Pluto. Patrick Moore discusses with Iain Nicolson the information and pictures we may get back from these missions. He also talks to Professor Clyde Tombaugh, the discoverer of Pluto.
