NASA Watch: "Bob Zubrin Steps In It Again"

More uses for a gas giant (I think this one is from John
Schilling): use the planet to brake small, extremely dense bodies
almost to orbital speeds, then finish the job within the small
bodies of the rings (Obviously, Jupiter wins in the "a very large
planet" contest, while Saturn wins in the "huge ring structures"
contest). This might allow us to recover stranglets and other
such exotic materials.

I'd take a close look at any small body with an unexplained
internal source of heat energy.

Enceladus?
