Patrick Moore helped to map the surface of the moon .
Over the years he received many lucrative offers to take his programme onto other networks , but rejected them because he held a 'gentlemen 's agreement ' with the BBC.A highlight of the series in 1959 was when the Russians allowed Moore to be the first Westerner to see the photographic results of the Luna 3 probe , and to show them live on air as a reward for his assistance in mapping the lunar surface .
