CRaBSS (Characterizing Radiation Belt Sources and Sinks) was a planned 6U CubeSat mission developed by NASA's Goddard Space Flight Center.

The mission was to provide a training opportunity for young scientists and engineers. It was to enhance the science return of the RBSP mission by providing conjugate measurements at the high altitude foot points of the outer radiation belt magnetic field lines and to resolve the "loss cone" and provide reliable measurements of how many relativistic electrons are being removed from the radiation belts via impact with the Earth's atmosphere.

The satellite's payload was to consist of:

  • Compact Relativisitc Electron Proton Telescope (CREPT)
  • Spectrometer for NeUtrons and Gamma-Rays (SNuG)

It was selected in 2013 by NASA's CubeSat Launch Initiative (CSLI) to be launched as part of the ELaNa program., but was cancelled due to a lack of funding.
