Richard Binzel, Professor of Planetary Sciences and Margaret MacVicar Faculty Fellow, discusses the summer 2017 solar eclipse, the New Horizons mission, and fields questions from alumni.
Richard P. Binzel is Professor of Planetary Sciences and Margaret MacVicar Faculty Fellow. He is one of the world’s leading scientists in the study of asteroids and Pluto. As the inventor of the Torino Scale, a method for categorizing the impact hazard associated with near-Earth objects (NEOs) such as asteroids and comets, his ongoing telescopic research includes the spectral characterization of asteroids posing a potential hazard to Earth as well as those that may be most easily reachable by future robotic and human missions. His scientific analysis has shown the link between major meteorite groups and their formation and source locations. Asteroid number 2873 bears his name, an honor bestowed by the International Astronomical Union in recognition of his contributions to the field. His mapping efforts of Pluto in the 1980s revealed a diverse surface entreating for exploration, finally achieved in 2015 as a co-investigator on NASA’s New Horizons mission. He is also a co-investigator on NASA’s OSIRIS-REx asteroid sample return mission where he leads the development of the student-built flight instrument, the Regolith X-ray Imaging Spectrograph (REXIS).
