How did you decide on the final shape, instrumentations and the name of New Horizons?

Ulysses probe to Jupiter which also had just 1 RTG, unlike Voyager’s 2 RTGs. The instruments were

Thanks! More success and more extended missions! Is there already a list of Target Objects at the
Kuiper Belt? How many are your prospect for the entirety of the mission?
