Ion engine could one day power 39-day trips to Mars
Here's something that I found online that looked pretty interesting. I'm a star wars junky (as well as star trek if you couldn't tell by my avatar...) and this technology is used pretty consistently in the movies. Hard to believe that it could be reality. In fact, ion engines are already in use today, but not over a wide-spread basis. Pretty awesome way to get some propulsion...

Trivia Fact: The "bad guys" in star wars fly what are called TIE fighters. Anyone care to guess what TIE stands for? It stands for Twin Ion Engines!!
