ion engines?

[cyrostir]

What do you guys think about new propulsion systems, such as ion engines powered by nuclear reactor? Is this just a theory or is it in being developed? I know there is a ion engine powered SMART-1 craft, but thats all i have heard of...

The DS-1 mission used solar panels to power the ION engine used by DS-1.<br /><br />Also a page of links for ion engines from Space.com<br /><br /><img src="/images/icons/smile.gif" /> <div class="Discussion_UserSignature"> </div>
