Hi all,

I never tire of imaging this crater and its neighbours. One the most elegant of these is the ghost crater, Spurr, named for Josiah Spurr (1870-1950), an American geologist who pioneered the exploration and geological understanding of great swathes of Alaska as well as working all over the world. He wrote several books about the geology of the moon - ahead of his time in his contributions to these fields.

Rimae Fresnel are named for the French optics physicist Augustin-Jean Fresnel (1788-1827). Fresnel invented the catadioptric lens - the Fresnel lens - which is still used in lighthouses to this day.

When he wasn't making interesting lenses, Fresnel helped prove the wave theory of light, elucidated polarisation, and one of his devices, the Fresnel Rhomb, supplied inspiration for naming the punk band, Frenzal Rhomb, who have given us such memorable albums as "Smoko at the Pet Food Factory" and "Forever Malcolm Young". You just don't know where science will take you.....
