The only "done deal" is $ 30M in the current year budget. There is NO request for additional money in FY 03 from the administration. $ 30 M sounds like a lot, but it's about 1/20th the amount needed to fly this thing. Congress may try to add money, but it'll take at least $150 M in '03 to get the project where it ought to be; that's not an easy "add-on" for pork. It's likely that this thing is finished.
"The House and Senate ultimately went against NASA and Bush administration wishes by including $30 million for the Pluto Kuiper Express mission."
Looks like it is up to Congress. I'm not an advocate of the Pluto-Kuiper Mission; Pluto is not going to be important to space exploration for a long time to come, even if now is an opportunity to explore the planet before its atmosphere freezes once again. The next opportunity will be in a couple of centuries. Pluto can wait.
