Oral Presentation at the Venus Special Session – 53rd Lunar and Planetary Science Conference.

For my master’s research, I mapped structures and geologic units seen in the Alpha Regio tessera on Venus using radar remote sensing datasets. The main objective of my thesis was to produce a full-resolution Magellan (~100 m) geologic map of the target descent site for the DAVINCI mission. Structural features are mapped as ridges, troughs, grabens, or lineaments. The orientation and spacing of these structures, along with radar backscatter properties, elevation, and morphological patterns are used to map out geologic contacts and define morphotectonic units.

This map will help correlate images taken by the Venus Descent Imager (VenDI) camera to the correct location on the planet during and after the probe’s descent, providing a clearer understanding of the geologic history of the tessera.

I also applied a simple extension model of lunar graben to two mapped sets of graben in the region to estimate the thickness of the Alpha Regio tessera faulted layer at the times of their formation.
