Maybe they ought to ask how they can ever expect to find evidence for life
on Mars (the presumed impetus behind the probes) when they can't concoct a
reasonable scenario for having it happen here. Certainly nobody would
assert that the Martian environment was more hospitable to life than the
one posited for earth!??? Of course all of us want to learn more about the
planets and the universe, but it isn't much fun to see billions of dollars
being lost in an effort directed toward an unrealistic goal.
