OSIRIS-REx Tech - Surveying an Asteroid with X-rays

The video discusses the REXIS instrument on the OSIRIS-REx spacecraft, designed to study the asteroid Bennu. REXIS is unique in its ability to detect atomic elements through X-ray fluorescence, providing a map of Bennu's surface composition. The instrument consists of a telescope and a solar X-ray monitor, with students from MIT and Harvard playing a significant role in its development. REXIS represents a new generation of X-ray imaging for planetary science.
