Keeping Its Best Face Forward
« on: April 04, 2019, 12:51:35 AM »
AS17-134-20509 thru 20513 found the lander prop wanting to only be photographed from its best side.

As the photog moves to the left, the stage set terrain in the foreground and the flag move right, and the fake background shifts left as indicated by the mound of whatever that was originally hidden behind the lander prop.

Problem is, the lander prop never shifts in orientation as the photog moves to the left. Come on prop lander, all your sides are beautiful! Show us!

I'd post a Picard facepalm, but I'm too lazy to find one.

Actually it clearly does.  Of course there are detailed methods for recovering the orientation in three dimensions of an object of known shape such as the lunar module.  But a first-order approximation can be had in this case by observing the ratio of horizontal distance between known points on the landing gear struts.  This ratio is clearly different in the two images.

Isn't this just a rehash of the old Jack White claims?

Except it quite clearly does change orientation. How far do you think the photographer has moved, and what kind of change do you expect to see?

It's another variation on "the backdrop is always the same", except, when you check, it isn't.
