Firefox seems to rewrite this internally (at least it immediately switches to www.nasa.gov and HTTPLiveHeaders does not show a redirect), but in IE, Chrome and Opera it fails.
Camino turns me right around back into this thread after showing its title (not the URL) in the address bar.
Safari plays dumb unless I prepend http:// and then it gives the generic "can't find the server" error.
Going back and trying http with Camino, I get the same behavior you describe in Firefox.
A random sampling of other dot gov sites leads to the appropriate redirect. (Hee, hee. You wouldn't expect the CIA to be concerned with Duplicate Content, would you?)
