Tooting horn

I was happy to hear about India's successful moon rocket launch attempt. I must say that I consider myself lucky to have designed minor portions of that rocket when I worked as an engineer for the Indian Space Research Organization ten years ago and it sure was heartening to hear this news today. The mission seems to have a couple of stated objectives - firstly, to create a three dimensional surface topology map of the moon and secondly to find and map uranium/thorium deposits under the lunar surface... The former makes perfect sense, the latter none.
