Many people at NASA beleive that further space exploration is basically unreasonable without using nuclear rockets. Of course, on the other side of this table is a public that has been taught to fear nuclear technology. With the Cassini probe, honestly, I couldn't tell who was right. Both groups were sure they were right, but neither group could convincingly counter the opposition, IMHO. However, I heard a lot more volume from the anti-nuke crowd then from Nasa, so I thought I'd "meme" this.
