Biography

Mark Matney is a planetary scientist and modeling lead for the Orbital Debris Program Office within the Astromaterials Research and Exploration Science (ARES) Division at the Johnson Space Center. Matney's work involves all aspects of orbital debris research including measurements, modeling, and mitigation. Orbital Debris is a major (and growing) source of hazard to both crewed and robotic spacecraft - especially in low-Earth orbit. NASA is a world leader in understanding and helping mitigate the risk for all users of space - both U.S. and international.
