Apollo Mapping Bug....Or something else?

a reply to: erikthegreen

They say the film was hand cleaned and then scanned so I guess it must of been picked up there.

The debris was inside the camera that took the image. It had nothing to do with the scans.

Your "find" is one of many examples from the same camera. All of different shapes and sizes.

Wouldn't that make it blurry like you said or am I missing something?

a reply to: erikthegreen

No. It is casting a shadow directly on film. It the same way the marks on the reseau plate cast shadows of crosses on the images from the Hassleblads.

Thanks for the help. I'll just optimistically say it was a space mite that snuck in there.

There are 2616 Metric Mapping Camera images and 1529 Panoramic Camera images for Apollo 15. The counts are on the site I linked to.

The cameras were mounted outside the spacecraft and away from any human interference and the sealed magazines were retrieved on the way home, so any issues with the film are either going to be post mission or there to start with and should be every image.

Not strange at all, just bits of dirt. As I said already - if they were genuinely anywhere near the moon then any objects would appear in both Metric and Panoramic camera images as they were taken at the same time of the same locations.

Can you please share the link of the gallery so we can view from the OP?

a reply to: erikthegreen

certainly :

The preparation of successive positive and/or negative reproductions from an original negative and/or positive (first-generation). For example, the first positive produced from an original negative is a second-generation product; the negative made from this positive is a third-generation product; and the next positive or print from that negative is a fourth-generation product.

the peice of film that was exposed in lunar orbit - was developed as the 1st gen negative

from that all subsequent copies - both positive and negative have been made

and many of these have been scanned too to create digital image files

By way of returning to the original bug in the Apollo 15 images, as part of my own education in learning stuff I plotted Apollo image A15-M-09933 on top of a surface elevation map provided by Japan's Kaguya probe.

The result is here:

extract the winrar file and open the .html one in the folder it creates (best done in Chrome). Use your mouse controls to move around.

See if you can spot the bug

The first page has the link...look at my posts

Pretty cool...you scaled the image and oriented it to drop right over the displacement map? When did the probe get that?

Good work. The bug is still there. Not sure what that proves.

Would be great to put them all together and generate a larger 3d representation....Probably a lot of overlap too and I guess that would be quite the operation....Lots of images ha.

Not sure when Japan's image was taken - sometime between 2007 and 2009! There are enough clearly identifiable reference points on the JAXA & Apollo photos to georeference (or should that be selenoreference?!) to line htem up exactly
