Characterization of Venus’ Surface Using Spaceborne SAR Data of Magellan Mission

Abstract. Venus is also known as Earth’s twin sister, remains one of the least explored planets due to its dense clouds and extreme surface conditions. The dense atmosphere blocks visible light and makes surface observation difficult through optical remote sensing methods. Advanced remote sensing techniques like Synthetic Aperture Radar (SAR) provide a better solution by using microwave signals that can penetrate the cloud cover and explore detailed surface characteristics of Venus. This study aims on the characterization of surface features of Idunn Mons and its surrounding region using SAR data from NASA’s Magellan mission. The analysis identified major surface features like lava flows, fractures, ridges, domes, craters, and other surface features, determined their area extent, and understood their elevation using global topography data. The correlation of SAR imagery with topographic information helps the generation of three-dimensional surface views improving the interpretation of Venusian terrain. The results highlight the effectiveness of radar and topographic datasets in surface feature mapping and their importance for studying the structure and geomorphology of Venus. This work will support future radar based planetary exploration missions to understand Venus’ mysterious geodynamics better.
