    It’s funny that we’ve sent number of pretty smart landers to Mars, and no one has been able to install on one of these a definitive test to say yes or no to life. Would one of these landers, if it was on earth (but of course with the camera disabled) be able to determine that earth harbors life? If not, then we’re not spending our money on the proper testing regime on these landers. Of course, maybe mission designers really aren’t looking for life at all; maybe they are afraid of what they will/won’t find, thinking the rest of us stupid, emotional rabble can’t handle the answer. Of course, we can wait for the ascendant Chinese to land there — you can be sure they won’t harbor a political correctness that inhibits them from telling it like it is. My bet’s with them; not NASA.
