Prop osal Title: Bistatic Observations of the Moon using Arecib o and the Mini-RF Receiver on the LRO Spacecraft ABSTRACT: Both Arecibo and Mini-RF have successfully mapped two thirds of the lunar surface including more than 99% of both polar regions. Analysis of these data has revealed the existence of permanently shadowed craters that have a radar signature consistent with the presence of ice deposits such as those seen on at the poles of Mercury (Spudis et al., 2010) but similar features are seen elsewhere on the moon, suggesting that they are due to surface roughness (Campbell et al., 2006). By conducting bistatic measurements of these craters, using AO and Mini-RF, we can distinguish between these possibilities. Due to hardware problems at Arecibo, none of the observations requested in the previous cycle could be performed. Outreach Abstract:
