It just occurred to me that I never heard so much as a peep out
of the anti-nuclear loonies about the RTG's carried aboard New
Horizons. Nothing on TV, nothing on the Net - absolutely nada. I
wonder what got up their noses so much about Galileo and Ulysses that
didn't with THIS particular launch?

Didn't I see somewhere that there were about 30 protesters at the
launch? (Looking it up, I did - probably here

Apparently 800 people protested over Cassini. Though the real nutters
were still protesting when it had problems at Jupiter - they thought it
might come back ;-)
