This reminds me, again, of a question that comes to mind every time NASA issues another press release about their confidence about finding evidence of life on Mars. Why have they never attached a single lousy microscope to one of these probes?

Is there any place on Earth where you wouldn't spot microbes if you looked closely enough? Imagine, further, packing stain reservoirs, polarizers, ultraviolet illumination, and what-have-you. Doesn't NASA have any laboratory biologists on staff?
