All hail King Kong of Mars! Eagle-eyed experts spotted this gorilla in one of the pictures sent back by the Spirit Rover. Of course, NASA's trying to cover it up. But it's not the weirdest Martian we've found so far.
Not only do some observers believe that's a gorilla running around on the red planet, but they believe the dark shape to its left is a second gorilla, as you'll see over at the Mars Anomalies web site. Enthusiasts have even gone so far as to create a Youtube video about gorillas fighting in the Martian mist.
