Gotta love this guy; Richard Hoagland is convinced of Machinery Found At Spirit Landing Site. They sure look like rocks to me.
As a point of reference, Mr. Hoagland is an ardent supporter of the ‘Face On Mars’ nonsense resulting from the unusual photo taken by a Viking Orbiter in the 70’s. Never mind those recent photos taken by vastly superior imaging systems onboard the Mars Global Surveyor and Mars Odyssey spacecraft that show an irregular mesa with no resemblence of a face – those photos are doctored by NASA to cover up the startling evidence of Martians. Yeah, whatever buddy.
