<tokenext>Hogwash .
The US may has been dicking around , but others have n't .
Your comment typifies everything wrong with the typical US attitude to space exploration.The Russians were in space almost continuously from 1971 onwards--from Salyut , through to Mir and then the ISS--running manned missions and supply flights almost continuously until the present .
The only pause in the Russian program was a couple years between the time Mir came down and the first ISS module was put up ( again , the Russians ) .From 1971-present the US could n't put a man in space for years over several periods : after Skylab ; after Challenger ; after Columbia .
Meanwhile , the Russians continued to grind along , slowly but surely , providing both manned and unmanned supply flights .
Those Progress and Soyuz flights that helped keep the ISS alive ?
Those were from Russia , using proficiences they developed during the 20 + years * regularly * servicing Salyut and Mir and maintaining a manned presence in space.Check the total time in orbit for the Salyut and Mir , days inhabited , and the number of missions--it 's pretty damned impressive .
And that was long before the ISS or the Shuttle.They were n't " dicking around " .
They were doing serious science on long-term manned missions , and what it takes to sustain an effort , especially from an operational/practical perspective .
It 's no accident that a lot of the practical ISS LS systems are based on what the Russians learned and developed .
NASA has refined some of those systems , but a lot of the basic tech ( air revitalization , toilets , etc .

<br> <br>
A straight up nuclear rocket, is anywhere from 5-10x better than say the space shuttle. (Is that a good guess? someone correct me)
Weight for weight and payload for payload. That means you could from ground to the moon and back to earth orbit in one vehicle.<br> <br>
More sophisticated designs with higher specific impulse make the trip to mars in a matter of months.<br> <br>
They have no details about what they are planning to do, except that this would not be a launch vehicle, but something more like a <b>interplanetary reusable shuttle</b>. If you use a nuclear reactor to power a Ion thruster or VASMIR rocket your talking incredible specific impulse that is a healthy fraction of a hypothetical fusion rocket. A VASMIR drive could make it to Mars in 39 days, a reccent slashdot article pointed out. In which case something like neptune is possible within a year.</htmltext>
