Okay, some people think it's a good idea, but others do not. There is really no other practical way to go long distances in space unless you have some kind of nuclear powered propulsion. It's either that, or go very slowly with chemical rockets. I would like to know what you guys think on the subject. Here are some helpfull links: Helium 3 can be used in Fusion reactors Nuclear Power Anti space nuke article interesting idea that unfortunately will probably never be used Fusion Rockets Here's good link, it doesn't deal with Nukes in space, but it is a good space site: Space Island Group If these guys were in charge at NASA, the ISS would have artificial gravity, and would be completed. You can also talk about the feasibility of what that site talks about. EDIT: Okay, got the links fixed.
