I'm not sure if we couple determine if their was life on Mars with scopes.
 But we certainly haven't really tryied.  But then at this range its alot
cheaper to just send a damn ship.  Over interstellar distences the cost
ratios change a lot.

Of course a lot depends on the biosphere.  At 1 meter res Earth would be
extreamly easy to verify as biologically active.  You could even spectra
scope the atmosphere for telltale chemistry with a lot less.
