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 gath…
