The Synthetic Pulse Artemis Radar for Crustal Imaging (SPARCI, pronounced “sparky”) is designed to measure the depth and structure of the lunar regolith. Southwest Research Institute has received a $2 million grant from NASA’s Development and Advancement of Lunar Instrumentation (DALI) program to develop the novel ground-penetrating radar instrument. This image shows the SPARCI receiver prototype in operation on a lunar analog on Earth.
