And remember the furor and controversy when we launched the Cassini probe. The anti-space people were all up in arms claiming that it was going to crash and kill off a huge chunk of the planet cause of nuke fuel scattering over the continent. (never mind that that's impossible, given the way the fuel is constructed and stored).
What happened? Cassini worked flawlessly, and has provided spectacular information back from Saturn & Titan.
Now, if you ever hear NASA talking about restarting up something called the Orion Project, then you would have something to worry about.
OK, I realize that will be overly cryptic for most people. Basically, the Orion project is a method of nuclear propulsion. We know it will work, but the side effects are... extreme.
Basically, you construct a space ship, big as you like, and stick it on a large curved metal plate, with a thin layer of an ablative substance like oil, etc. Seriously, size is no object. Want to launch an aircraft carrier into orbit? Orion will do it.
Basically, what you do is you punt a a-bomb out the back of the assembly, under the large metal base plate, and wait for it to go boom. The force of the explosion will lift the craft & plate up into the air, and the thin layer of oil ablates away, preventing the explosion from ablating the plate itself.
Then, you wait til the upward momentum starts to peter out, and you punt another a-bomb out the back, re-seed the oil onto the underside of the plate, and wait for that one to go off. The concave shape of the bottom plate helps direct the force to keep you going up instead of skittering off to one side, and you keep repeating the process until you finally make it to orbit.
That's the Orion project. The advantage is that you can literally lift any amount of weight into orbit. The scientists who designed the original ship were planning on deliberately bringing special barbers chairs that weighed 5 tons each, just because they could. The largest modern rockets can lift just over 20 tons into orbit. Orion could EASILY lift 20 THOUSAND tons into orbit.
The downside, of course, is that you've set off several hundred large atomic bombs in the atmosphere, in a vertical column. Not only is whatever you launched over going to be utterly destroyed, the fallout and environmental damage is going to be massive and widespread, to put it mildly. Lets just say that the impact of Chernobyl was minor compared to what Orion would do.
