Radar Studies of the Moon's Geologic History

We are requesting a total of 9.5 hours of combined Arecibo and GBT observing time to collect high-resolution, dual-polarization radar image data of the Moon at 12.6 cm wavelength. The requested observations address significant outstanding questions regarding the geologic history of the Moon's surface. Our recent work has led to the development of a method for focusing radar images collected over long integration periods, yielding spatial resolution as fine as 20 m, comparable to the best existing large-area spacecraft photos. The proposed work builds on analyses of similar 12.6-cm and 70-cm wavelength observations over the past several years that address issues such as ice at the lunar south pole, the origin of dark haloes around many impact craters, and the distribution of Mare Orientale related cryptomaria. Results of the 12.6-cm and 70-cm radar mapping pro jects have appeared in nine recent papers. Note - This proposal is very similar to that submitted for requested observations in September, 2007. None of the scheduled time could be used due to painting of the structure at Arecibo. We will recover one day in December, 2007, but this proposal requests three additional runs to make up the difference.
