VERITAS Scientists Study Rocky Terrain in Iceland

During their August 2023 Iceland field campaign, international science team members of NASA's VERITAS (Venus Emissivity, Radio science, InSAR, Topography, And Spectroscopy) mission prepare for lidar (Light Detection and Ranging) imaging of rocks at a study area. Lidar measurements of rocky terrain can provide information about the material, such as surface roughness. While the science team led by NASA's Jet Propulsion Laboratory gathered lidar data on the ground, their partners from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt, or DLR) carried out overflights to gather radar observations of the same study areas. By doing this, the team was able to ground-truth the radar data that will be used to help inform the science that VERITAS will do at Venus. VERITAS will peer through the planet's thick atmosphere with a suite of powerful science instruments to create global maps of Venus' surface – including topography, radar images, rock type, and gravity measurements – as well as detect surface changes. VERITAS is designed to understand what processes are currently active, search for evidence of past and current interior water, and understand the geologic evolution of the planet, illuminating how rocky planets throughout the galaxy evolve. https://photojournal.jpl.nasa.gov/catalog/PIA25839
