I saw the picture flipping back and forth ...no Mercury...no speck in my eye or your GiF., lol. Don't know why we want to observe things for ourselves when NASA handles these things quite well, but it caused me to think of the folly of sending human beings to Mars or beyond when the risk-benefit ratio favours using robotics. Isn't that what the aliens do?- they certainly don't risk cosmic radiation and micro-particle collision for the pride of transporting their flesh to distant worlds :) Yeah, tall grays or large headed dwarfs are robots for sure because, face it- if they were organic they'd surely look like us ha ha.
