Proposal Title: Digital elevation models of selected regions of Venus derived using Earth-based
radar interferometry
ABSTRACT:
We propose to generate high resolution digital elevation models (DEM) of the equatorial region of Venus between
Phoebe Regio and far western Ovda Regio using radar interferometry with Arecibo transmitting and Goldstone
receiving. We expect to generate DEMs with between 500 m and 1 km per pixel resolution. This would be more
than an order of magnitude improvement over the existing DEM based on Magellan altimetry measurements. The
new DEMs will be merged with Magellan imagery in order to investigate the relationship between the emplacement
of the plains and the tesserae. In addition, we will investigate the rifting process in Phoebe Regio which extends
through pre-existing tesserae terrain. Finally, a high resolution topographic model for the chasma may permit us to
generate new constraints on the mode of strain accommodation and eective elastic plate thickness in these regions.
