The Venus Emissivity, Radio Science, InSAR, Topography and Spectroscopy (VERITAS) Discovery mission will map the surface with NIR spectroscopy using the VEM instrument and SAR using X-band (4 cm) with the VISAR instrument [1]. The VERITAS Science team conducted a field analog campaign in Iceland over two weeks in August 2023 in collaboration with the German Aerospace Center (DLR), employing both an airborne radar mapping effort and an in-situ surface characterization task [2]. The latter serves as ground truth to the radar data by providing concurrent measurements of the parameters that control radar backscatter, such as topography, roughness, and dielectric permittivity. Here we report on in-situ permittivity measurements, sampling, and laboratory measurements.
