Space nuclear systems hold significant promise for providing sustained energy for a variety of space missions – including deep-space exploration, high-power spacecraft payloads, spacecraft maneuverability and persistence, surface power on the Moon and Mars, and long-duration crew and cargo transportation missions beyond Earth orbit. Development of these systems began in the 1950s and have been part of space exploration in various applications for decades. Launching, operating and disposing of space nuclear systems though poses unique safety challenges and risks, and with a marked resurgence in interest and funding for new space nuclear technologies and missions in the last decade, this committee looks to address some of those challenges. The purpose of the Space Nuclear System Safety Technical Committee is to create a forum for professionals in industry, academia, government, international agencies and national laboratories to collaborate on various topics of space nuclear safety. The vision of the committee is to serve as a forum to: 1) harmonize international goals and promote an internationally shared understanding of space nuclear safety, 2) study, disseminate, and increase awareness, and 3) educate and train engineers, space agencies, government and intergovernmental agencies, astronauts, and other stakeholders.
