Discovery of a Lunar Cold Spot at Apollo 16's South Ray Crater
Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.Abstract Lunar cold spots are extensive, ray‐like regions of reduced nighttime temperature surrounding young impact craters. Using improved Diviner temperature maps, we identify a faint cold spot surrounding South Ray crater at the Apollo 16 landing site.

A Goniometric System for Photometric and Polarization Measurements of Planetary Regolith Analogs
Earth and Space Science, Volume 12, Issue 9, September 2025.Abstract The Planetary Surface Texture Laboratory at the Johns Hopkins University Applied Physics Laboratory is a facility for the study of the photometric and polarization behavior of regolith analogs using an ∼1.5‐m‐radius arc goniometer system. This system characterizes the photometric and polarization response of granular materials (planetary ...
