CAS500-2
SNAPPY (Solar Neutrino Astro-Particle PhYsics), a 3U CubeSat developed by Wichita State University with support from NASA's Jet Propulsion Laboratory and Marshall Space Flight Center, became the world's first space-based neutrino detector. Rather than attempting to detect solar neutrinos directly, it measures background radiation rates in low Earth orbit, establishing the noise floor that will inform the design of a future larger instrument intended to operate closer to the Sun.
