Nuclear Rockets Moving Along

Posted by Hemos on from the building-towards-tomorrow dept.

AKAImBatman writes "Bruce Behrhorst of NuclearSpace.com recently stumbled across a new engine from everyone's favorite Jet Engine maker, Pratt & Whitney. Unlike P&W's previous engines, however, this engine is not a jet, and is powered by Nuclear Fission. It seems that P&W has responded to the need for Mars transportation by inventing the first commercially viable nuclear thermal rocket. They have heavily improved upon the NERVA NRX design from the 60's, and have even solved the graphite ablation problem! With this new engine, it seems that an inexpensive trip to Mars is now firmly within our grasp. Will we rise to the challenge?"

    I don't know what Kerry would do about the nuclear stuff.

    Build a rocket with a nuclear motor pointing up and a chemical motor pointing down.

    Oh yes, very safe, and don't worry when it does THIS in the upper atmosphere during launch. Everyone knows plutonium dust is perfectly healthy in really small quantities right? This is the fundemental problem with launching such engines into space - you're placing extremely toxic materials on top of a potential bomb. And what's the upside? This new engine only doubles the efficiency of a chemical reactor. I doubt that the result justifies the risk.

    Odd as it may sound, two thirds of Americans are currently in favor of nuclear power!

    Most Americans are in favor of garbage dumps too as long as it's not in their back yard and their taxes don't increase.

    Those sound like reasonable constraints to me.

    The public fears nuclear technology a) because it's something to fear (ever hear of Chernobyl? ever hear of Three Mile Island?); b) it is the ultimate product of military/industrial elitism, with its bland assumption that hoi polloi exist to be lied to, and that the world is best ruled in secret by a happy few.

    These are reasonable concerns. Your ill-tempered ridicule only calls your own character into question.
