Robotic Arm And Doorway Found On Mars, May 18, 2015, UFO Sighting News.

Date of discovery: May 18, 2015
Location of discovery: Mars

I was looking at some Mars photos and discovered that there was an arm on the ground. The arm looks robotic and powerful. It is not a delicate arm, but an arm for a robot that needs power claws and grasp. On one part of the arm...the joint between the end and the top, I did notice that there was a sort of hide with a bolt-like object on it. 

I also found a stone door in front of a cave. This doorway is about 2.5-3 meters high and blocks an entrance to a cave or may be an underground entrance to something more high tech like a base, but its camouflaged to look like the surrounding area. SCW
