Proposal Title: Radar Observations of Mars During the 2005 Opposition
ABSTRACT:
We propose to make S­band radar observations of Mars during the 2005 opposition. These will be the first Arecibo
observations of Mars since 1993 and the first using the upgraded radar telescope. The observations will be devoted
to delay­Doppler imaging using waveforms designed to mitigate or eliminate the e#ects of echo overspreading. The
increased sensitivity a#orded by the upgrade will enable us to make Mars radar images of unprecedented quality
and resolution. Images of the di#use/depolarized echo will be used to map out variations in small­scale surface
roughness, which is of intrinsic geologic interest as well as useful for lander hazard assessment. We will image
radar­bright features such as the northern lava flows and south polar ice cap as well as map out radar­dark features
such as ``Stealth'' and other putative ash flows and debris lobes. We also plan to make the first true
polarization­ratio images of the planet.
