20-EPN2-075: Emissivity Measurements of Proposed Source Minerals for Venus Anomalous Regions

Visit by Erika Kohler, NASA Goddard Space Flight Centre (UK), to TA2 Facility 5 – DLR Planetary Spectroscopy Laboratory (Germany).
Dates of visit: 1-15 December 2022

Report Summary: This study directly measured the emissivities of four Venus-mineral analogues at Venus relevant temperatures and reflectivity spectra pre- and post- heating. Mission and ground-based observations of Venus show several anomalous regions related to elevation, but the variations are unknown to be compositional or morphological in nature. The comparison of emissivity measurements from candidate minerals at Venus surface conditions and reflectivity measurements will demonstrate whether mineralogical composition can be identified in future Venus missions and will constrain the source of the Venus highland radar anomalies. The results of this study will maximise the return of previous and future Venus missions that take surface measurements by contributing to the database of Venus analogues being compiled at the Planetary Spectroscopy Laboratory.
