The Royal Institution Annual Christmas Lectures to Young People
4: Mars Before Viking
Six years ago almost to the day, our knowledge of the planet Mars was transformed virtually overnight as a huge duststorm cleared to reveal the planet's face to the orbiting spacecraft Mariner 9. It was a key moment which Professor Carl Sagan personally witnessed, as one of the Mariner 9 science team.
Sagan relives that moment in today's lecture and describes with the aid of dynamic models the incredible wealth of craters, volcanoes, ice sheets and ancient water channels that Mariner 9 photographed.
