China has successful launched a probe expected to enter orbit around the Moon on 6. December and make landing the following week in a lunar region called the Bay of Rainbows—Sinus Iridum, an area relatively flat and free and free of craters being a youngish plain of an ancient lava flow and not far from where the Soviet Luna 17 probe touched down in November of 1970 and bounded by the Jura mountain range—of the Moon.
Boing Boing covers the news nicely, whose mission objectives and technical specifications were kept secret until right before pre-flight. The probe's duties include high-resolution photography and soil sampling (which is nothing to be sniffed at), with the eventual aim of establishing a base for unmanned exploration. I especially like how the rover is characterised as massing in at 140 kg as Earth weight has a variable meaning once free of Earth gravity. A lot of earthling terms, night and day and coordinates of longitude and latitude take on new meanings when applied as a template, but its interesting to note how observation, compromise and mathematics applied to the real and apparent lunar cycles have influenced very mundane customs, like the Chinese calendar and, in turn—time and tide, for forecasting and planning purposes around auspicious dates. Converted from the Western calendar, touch-down is 11/12/13 and I'm sure qualified astrologers could say more about that.
