Proposal Title: High-Resolution 70-cm Radar Imaging of the Lunar South Pole: Searching for
Evidence of Ice
ABSTRACT:
The presence of ice at the lunar poles remains a topic of considerable interest. We propose to carry out 70-cm
wavelength radar mapping of the lunar south pole, using the Arecibo and Greenbank telescopes to obtain dual
circular-polarization data. These measurements will permit deeper probing of portions of the
permanently-shadowed crater oors than was possible with either the Clementine 13.2-cm or Arecibo 12.6-cm
observations. Our results should provide much better constraints on the physical nature of possible ice deposits
within these shadowed regions.
