Much as I'm delighted by ESA's recent achievements, I think NASA's programme in terms of solar system exploration is pretty healthy for at least the next 5 or 6 years:

2005: Deep impact at comet Tempel 1, launch of Mars reconnaissance orbiter, continuation of Cassini's studies
2006 - Launch of new horizons to Pluto/Charon/Kuiper belt and Dawn (Ceres and Vesta orbiter)
2007: New horizons reaches Jupiter and conducts mapping of the Galileans, and launch of Kepler (extrasolar terrestrial planet detection mission)
2008 - Messenger's first and second Mercury flyby, probable Cassini mission extension
2009 - launch of Mars scientific laboratory (another surface rover), and third Mercury flyby by Messenger
2010 - Dawn arrives at Vesta and begins studies
2011 - Messenger enters orbit around Mercury, Dawn leaves Vesta orbit en-route to Ceres, JIMO launches to study Galileans from orbital positions.

As long as fantastic science like this continues to be funded one way or another, that's all to the good. Healthy rivalry can only improve the situation, and co-operation such as that with Cassini-Huygens benefits all.

p.s. Don't forget the Japanese and their asteroid/comet sample return missions.........
