Tiny CubeSat Probes Solar Neutrinos from Low-Earth Orbit
NASA-supported SNAPPY, a half-pound CubeSat, launched from Vandenberg AFB to test a solar neutrino detector in a low-Earth polar orbit, featuring four crystal detectors shielded with tungsten-dust epoxy and an electronics stack on a Kongsberg NanoAvionics platform; the mission, funded by NASA's NIAC program, aims to validate detector performance in space and inform future near-Sun detectors, with contributions from NASA centers, Wichita State University, and other partners.
