Machinery Found at Spirt Landing Site

or

Rise of the Gibbous Moon

This is just ridiculous. It's like they didn't even try. It looks like what they've done is take one of the panoramic views, blown up pictures of random rocks, and claimed that the rocks are machinery. What makes this guy think that any of this is machinery? It all looks like rocks to me.

Come on... If you're going to do this, do it right. Photoshop something into the picture... Do you think the machinery is the wrecked remnants of an ancient lost Martian civilization? Extrapolate from the wreckage and give us an artists rendition of what the machinery used to look like.

I really expected more from the Enterprise Mission. You guys ought to be ashamed of yourselves.
