USA Today (Oberg): "Think outside moon-Mars box: Maybe visit asteroid"

Asteroid? That'll never happen. A moon has much more clout than some rock
flying through space, even if it's more challenging. It's a psychological
kind of thing.

"The White House plan, detailed in internal documents, also
mentions the possibility of sending humans to asteroids or
moons of Jupiter."

Europa! By robot or by manned mission, we really need to find out if
anything lives in that sea.

Probably not Europa (unless they could burrow in under the ice). At
least at first. Or Io or Ganymede. But Callisto, as I understand it, is
far enough outside the Jovian radiation belts for humans to survive; and
it could be used as a forward base.

It's got its own gravity well. Find a little prograde satellite near the
equatorial plane, and burrow into that.

But then you have got the same health issues of dealing with
weightlessness (or next-to-weightless) as you would have on a long space
voyage, with an additional complication of one possible solution (spin
the spacecraft to create artificial gravity) being not an option.

IF you can get an unmanned probe to Europa...and find even primitive
life...it justifies NASA's mission. If you find weird cool multicellular
lifeforms not existant on earth(Europan jellyfish style animals,etc)
....you can write your own check.

I think there's been a **sponge** photographed on Mars by Spirit. Looks a
bit dangerous, too:

Dangerous? I would have thought insane was a better adjective.

That proves they are not taking this at all seriously. An interstellar
probe to Alpha Centauri is right now way more feasible than sending men
to moons of Jupiter. Not that comparing impossibles is all that useful.
