By Theresa Hitchens on April 19, 2021 at 12:54 PM Demonstration Rocket for Agile Cislunar Operations (DRACO), DARPA image WASHINGTON: DARPA’s effort to develop nuclear ‘engines’ for far-roving satellites also hopes to demonstrate the capability to keep “timely” tabs on spacecraft operating near the Moon, says program manager Maj. Nathan Greiner. While cislunar surveillance doesn’t require nuclear-propulsion, such a spacecraft could move more rapidly into position to monitor targets of interest. It might also mean the spacecraft would be able to remain active for a longer period thanks to the fuel. “Some of this is classified, so this answer must be rather general,” he said in an email, explaining that the Demonstration Rocket for Agile Cislunar Operations (DRACO) program has two key goals: ....

DARPA awards 3 deals for work on nuclear propulsion system By (0) The Defense Advanced Research Projects Agency awarded three contracts this week to design a nuclear thermal propulsion system. Photo courtesy of DARPA April 15 (UPI) The Defense Advanced Research Projects Agency awarded three contracts this week to design a nuclear thermal propulsion system that will operate above low Earth orbit in 2025. General Atomics, Blue Origin, and Lockheed Martin are the prime contractors for the deal, according to a DARPA press release. Advertisement The Demonstration Rocket for Agile Cislunar Operations (DRACO) program has the potential to achieve rapid maneuver in space, which has been challenging because current electric and chemical space propulsion systems have drawbacks in thrust-to-weight and propellent efficiency, respectively, according to the agency. ....
DARPA selects three prime contractors for DRACO program Shane McGlaun - Apr 15, 2021, 5:01am CDT DARPA has announced that it has awarded contracts for the first phase of the Demonstration Rocket for Agile Cislunar Operations (DRACO) program. The program’s stated goal is to demonstrate a nuclear thermal propulsion system above low Earth orbit by 2025. The trio of prime contractors selected by DARPA includes General Atomics, Blue Origin, and Lockheed Martin. DARPA says that rapid maneuvering is a core tenant for modern DoD operations on land, sea, and air. However, rapid maneuvering in space has been challenging due to electric and chemical space propulsion systems in use today. Those systems have limitations in thrust-to-weight for electric and propellant efficiency for chemical propulsion systems. DRACO’s nuclear thermal propulsion system has the potential for high thrust-to-weight ratios similar to in-space chemical propulsion while approaching ....
