Fission reactor with a leak, I like it. I would much rather see this built in orbit for fast (real fast) trips to the Moon and Mars and a rebuild of the Saturn 5 to boost the required hardware. Enviro weenies can't complain and the Saturn 5's safety record was 100%. Not to mention, the Saturn 5 was just cool.....

<>. Enviro weenies can't complain...

But they will anyway, being enviros - there just isn't a whole lot they can do about it.. They tried to stop Galileo and Cassini, didn't they, which also operated only outside the Earth's atmosphere.
