The Sky at Night
The Changing Face of Mars
Not Rated
S20 • E1 Jan 21, 1976The planet Mars is brilliantly visible in the sky at the moment. It has always been regarded as the one planet beyond earth upon which life might exist, and in 1976 we could find out at last. Two American rockets, the Vikings, are now on their way to the Red Planet, and should land there next summer, transmitting information from the Martian surface. Patrick Moore and Dr Garry Hunt look forward to what the Viking probes may tell us.
