NASA, DARPA enlist Lockheed to build nuclear-powered spacecraft
NASA's ambitions to speed up space travel are about to go nuclear, as its joint project with military boffinry unit DARPA has found a builder for an experimental nuclear thermal rocket vehicle, or X-NTRV: Lockheed Martin.
"An NTR achieves high thrust similar to in-space chemical propulsion but is two-to-three-times more efficient,"DRACO program manager Tabitha Dodson, meaning far less propellant would be needed to do things like transport supplies to the Moon - or further to Mars. "With a successful demonstration, we could significantly advance humanity's means for going faster and farther in space and pave the way for the future deployment for all fission-based nuclear space technologies," Dodson added.
