NASA seeks to launch a nuclearpowered rocket engine in four years

News Summary
- NASA and the US Department of Defense are partnering to develop a nuclear powered rocket engine for in space transportation
- A nuclear reactor rapidly heats up a propellant probably liquid hydrogen and then this gas expands and is passed out a nozzle creating thrust
- Traditional chemical propulsion is great for blasting rockets off the surface of the Earth but such machines are terribly inefficient for moving around the Solar System
- NASA is looking to go to Mars with this system said Anthony Calomino an engineer at NASA who is leading the agency s space nuclear propulsion technology program
