Meet the Student Engineering Building REXIS

Meet the MIT student engineers who are assisting NASA with asteroid exploration. These student engineers in our Space Systems Laboratory built an instrument called REXIS, to fly on the OSIRIS-REx spacecraft. REXIS will collect and image fluorescent X-rays emitted by asteroid 1999 RQ36,  providing spectroscopic information on the chemical makeup of the asteroid regolith and the distribution of features over its surface.
