Earth-based telescopes can't be used to find an Apollo lander on the moon. It's just too damn far. A crater on Mars is a notch up from that.

  Some great info about just why this is so impossible: http://calgary.rasc.ca/moonscope.htm http://calgary.rasc.ca/moonscope.htm

    Interesting - how is it they can accurately target the puny "lunar laser ranging retroreflector array" but not see the landers?

      The laser is 6.5KM wide when it reaches the moon. http://en.wikipedia.org/wiki/Lunar_Laser_Ranging_experiment http://en.wikipedia.org/wiki/Lunar_Laser_Ranging_experiment

        Awesome! I see they lost the Soviet Lunokhod 1 array for nearly 40 years!
