LOL, that video never gets old. :) Sad thing is that the whole "Submarine Aircraft Carrier" thing was done before plenty of times in the past. :)

No Russians had underwater launch capable missiles for a long time. The one that's currently being used is USSR era R-29RM Sineva SS-N-23 missile and will be replaced by Bulava missile. Bulava missile was strongly pushed up in research only due to active expansion of NATO bases and missile shield construction plans in Eastern Europe. Either way, as soon as missile shield plans were announced, Russia started dropping billions into anti missile shield projects such as Bulava and Topol-M to maintain nuclear deterrent.

Simple! That's because all of them were still under warranty!!!! :)

Last I recall there was already a craft with nuclear propulsion launched a while back, not to mention a good share of nuclear powered satellites are already up in orbit. Space is full of radioactive particles, so it's not a big deal.

I do agree with Rei. NASA needs to fund research a little better at this time, instead of trying to waste available resources on useless missions. If they would just push technology research just a few years, they could have a lot of options to choose from to accomplish their goals a lot more efficiently. I realize that by going to Moon, it could increase public interest and potentially gain additional funding for technology research related projects, yet it can also backfire in many ways which could set NASA back later on.
