A “resurgence of interest” in nuclear propulsion for space missions is described in a new article authored by science writer Jon Kelvey for the American Institute of Aeronautics and Astronautics’ (AIAA’s) Aerospace America website. The focus of Kelvey’s article is nuclear thermal propulsion (NTP), which, according to the Department of Energy, “could significantly reduce travel times and carry greater payloads than today’s top chemical rockets­—giving humans a great chance of exploring deep space.”
