CXBN

Cosmic X-ray Background Nanosatellite (CXBN) was a satellite and mission developed by the Morehead State University. Unlike its successor, it was a partial failure as its transmissions were too weak for its mission due to it going into an anomalous low power mode. It was supposed to take measurements of the cosmic X-ray background in the 30-50 keV range and temporarily supplement NASA's Radiation Belt Storm Probes.
