First-Hand:Studying the surface of the moon by radar
submitted by John Evans
As a PhD student in the UK, I was responsible for studying the moon by radar, and established that, for the most part, the surface was sandy, smooth and undulating and not hazardous for humans to land on. These findings were later confirmed by close up photographs taken by NASA. The work was published in 1957 and caused studies undertaken by the US Navy that had reached similar conclusions, but had been classified, to be released. This encouraged the thought of a moon landing at a time when optical astronomy could not resolve features on the moon's surface smaller than 1/2 kilometer.
