Regolith X-Ray Imaging Spectrometer (REXIS) Aboard the OSIRIS-REx Asteroid Sample Return Mission by Masterson, R. A, Chodas, M., Bayley, L., Allen, B., Hong, J., Biswas, P., McMenamin, C., Stout, K., Bokhour, E., Bralower, H., Carte, D., Chen, S., Jones, M., Kissel, S., Schmidt, F., Smith, M.

“…Abstract The Regolith X-ray Imaging Spectrometer (REXIS) is the student collaboration experiment proposed and built by an MIT-Harvard team, launched aboard NASA’s OSIRIS-REx asteroid sample return mission. REXIS complements the scientific investigations of other OSIRIS-REx instruments by determining the relative abundances of key elements present on the asteroid’s surface by measuring the X-ray fluorescence spectrum (stimulated by the natural solar X-ray flux) over the range of energies 0.5 to 7 keV. …”
