Novel data are presented of Bidirectional Reflectance Distribution Function (BRDF) and 8° directional/hemispherical reflective measurements of Martian regolith simulant JSC Mars-1. The scatterometer of the National Aeronautics and Space Administration's Goddard Space Flight Center (NASA's GSFC) Diffuser Calibration Facility (DCaF) was used for the measurements reported. The data were obtained with a monochromator-based light source in the UltraViolet (UV), Visible (VIS), and Near InfraRed (NIR) spectral regions. The BRDF measurements were performed at different angles of incidence, and over a range of in-plane and out-of-plane geometries. The 8° directional/hemispherical reflective measurements were calibrated using a gray Spectralon sample set of 7 plates. The results presented are NIST traceable through calibrated standard plates. The hemispherical and diffuse scatter data obtained from these studies are important for future Mars space and ground based observations.
