Why fix what? What is NH's problem with this? Instead of visiting the last remaining planet, looking like a compulsory excercise to complete the list, now it is really a new horizon. The first spacecraft dedicated to the Kuiper belt, the first closeup look at a KBO! Those objects astronomers of today are trying very hard to get tiniest bits of information from with enormous efforts, and this thing is actually going there!
So do I. And from Charon please!
