LOL, nothing in the solar system anyway, afaik. But who knows? Maybe there is a tenth planet lurking out there at a thousand AU or so. Of course, there's the Oort Cloud itself and that would be real interesting. But surely the Pluto team isn't planning on visiting that -- or beyond! At least not in this primitive age of chemical propulsion.
BRING BACK ORION! BRING BACK ORION! BRING BACK ORION!
Why waste money on Pluto right now. I would rather establish a permanent moon base or explore Mars. Pluto can wait as its going to be a long time before it does us any good. parsy the practical spaceman.
