It’s nice when every once in awhile, there’s something large enough, close enough and not obfuscated for whatever reason by NASA to have a decent look at it. Such is the case in today’s Context View, where we see a big chunk of something down in the lower right-hand corner.

Moving into Detail View #1, we see what at first glance might be an eroded boulder. Odd angles, knobs and channels could be the result of relentless chiseling by wind and sand. But here are the two considerations that mitigate against this being a naturally-eroded boulder: non-fractal angles and bilateral symmetry.

Going to Detail View #2, we get in good and tight to examine whatever this is. Note the following: Parallel sides of the same shape and thickness; a squared-off end on the right with perfect ninety-degree angles everywhere; four symmetrical grooves cut into the squared-off end; two parallel protrusions catching the sunlight on the front right end, both the same shape and thickness.

This is not stone, but corroded metal. IMHO, this is a battered and corroded piece of industrial equipment; another piece of mute testimony to the utter devastation that was Mars’ turning point.

“SO, HOW DO I VIEW X3D STEREO?” 

Simple! While viewing the stereo pair at a comfortable distance, gently cross your eyes (no eye-strain) until you perceive three images all the same width. The one in the center is in 3D. Just relax into it and your eyes will automatically bring it into focus. Once you have it, you will never forget how to do it. Kinda like riding a bicycle…
