Mission Description

  • Goal is to increase the precision of measurements of the Cosmic X-Ray Background (CXRB) in the 30-50 keV range.
  • Constrain models that explain the relative contribution of cosmic X-Ray sources to the CXRB
  • Produce data that will lend insight into the underlying physics of the Diffuse X-Ray Background
  • Provide flight heritage for CZT-based X-Ray gamma-ray detectors and CubeSat technologies
  • ConOps: Sun pointing, 1Hz rotation, maps entire sky in the X-Ray spectrum
