It appears that Congress wants a Hubble servicing mission in 2007. Hopefully the launch of Discovery on (or about) the first of July will go flawlessly and make that possible. The Spitzer and other similar tools are cool and all, but we love our Hubble eye candy too.
The above I learned from here, which also has the following comment I found amusing:
"One of [the House] recommendations includes $15 million for NASA to study and plan for a new start on a Europa mission as part of its fiscal year 2008 budget request."
Not only do they love eye candy, but in addition they've been reading Arthur C. Clarke and realized we're about five years late right now and need to catch up. I'm cool with us going to Europa, though, so long as we attempt no landing there.
