“NASA is working on a propulsion system” but I don’t put put too much stock in it at this point (see link below). When NASA goes back to full on nuclear propulsion (like the NERVA nuclear engine) then you know they are serious.
Meanwhile, NASA is somthing of an inside joke, other than it’s robotic missions.
