Promises revolutionary gains in performance, leveraging sixty years of evolving technologies
BERKELEY, Calif., March 22, 2022 — Dark Fission Space Systems, an early-stage space start-up, aims to accelerate the expansion of the space economy beyond Low Earth Orbit through the development and deployment of the first commercially available nuclear thermal rocket (NTR) engine. Led by Dr. Fred Kennedy, the Dark Fission team will combine years of NTR design evolution with modern advances in computing, manufacturing, and materials to produce a safe and reliable in-space propulsion capability with performance characteristics exceeding anything available today.
Industry teams to develop propulsion design, spacecraft concepts for demonstrating on-orbit Nuclear Thermal Propulsion (NTP) system
ARLINGTON, Va. (DARPA PR) — DARPA has awarded contracts for the first phase of the Demonstration Rocket for Agile Cislunar Operations (DRACO) program. The goal of the DRACO program is to demonstrate a nuclear thermal propulsion (NTP) system above low Earth orbit in 2025. The three prime contractors are General Atomics, Blue Origin, and Lockheed Martin.
NASA’s Space Technology Mission Directorate requested the National Academies of Sciences, Engineering, and Medicine to convene an ad hoc committee to identify primary technical and programmatic challenges, merits, and risks for developing and demonstrating space nuclear propulsion technologies of interest to future exploration missions. The particular systems of interest were specified as nuclear thermal propulsion and nuclear electric propulsion systems. The committee was also tasked with determining the key milestones, a top-level development and demonstration roadmap, and other missions that could be enabled by successful development of these systems.
Just days after the successful full mission-length test firing of the nine-engine first stage of the Falcon 9, Space Exploration Technologies Corp. (SpaceX) marked another significant advance with the performance of its smallest rocket engine, Draco. Known as a â€œthruster,â€ the new engine fired continuously for ten minutes in a specially constructed vacuum test chamber that simulates the space environment. After a ten-minute thermal soak period, Draco was restarted for an additional minute, simulating its typical use in space. (Video)
