That's why NASA planetary scientist Christopher McKay, in an article in this week's Science, suggests the need for a stronger policy that ensures all exploration of Mars be "biologically reversible" - meaning we would be required to effectively wipe away our footprints and remove any possibility of contamination, by leaving behind nothing that could foster alien microbial growth. Such a policy would be especially necessary if we discover that life on Mars has emerged independently of life on Earth - what McKay calls a "second genesis" - as opposed to Martian life that arose through the exchange of meteorites between Mars...

...don’t have a lot of faith in words myself; the average person tells three lies per ten minutes of conversation.” Behind the one-way mirror, an FBI agent gruffs, “We don’t have time for this scientist to talk to the guy.” Within a minute of this skeptical remark, Dr. Lightman determines where the suspect planted a bomb based solely on a microexpression that flits across the man’s face.
