NASA said nuclear thermal rockets can be three or more times more efficient than conventional chemical propulsion and would reduce transit time, essential for an eventual mission to Mars.

Nuclear thermal propulsion (NTP ... produce higher specific impulse (a measure of fuel efficiency) than chemical rockets, which means they can achieve higher speeds and use less propellant.
