The image is 824 meters wide, north up. Apollo 12 astronauts Charles "Pete" Conrad and Alan Bean landed here on November 19, 1969. Surveyor 3 landed on April 20, 1967. Credit: NASA / GSFC / ASU

UPDATE: Here's some interesting insight into this image from Phil Stooke: "The tracks will let us revise the [Apollo 12] EVA map - it's wrong in several places." Cool. Furthermore, he said, "Surveyor rode down on a retro-rocket, then discarded it and set down gently on small vernier rockets. That retro-rocket (especially its big spherical fuel tank) is somewhere near here, waiting to be discovered. I might predict that it will be the first piece of exploration hardware to be discovered in an LROC image, if a Lunokhod doesn't come along first." If you want to hunt for that lost (though, admittedly, unlooked-for) piece of Surveyor hardware, you can go here to download the full-size TIFF file of the LROC image. Keep in mind that there's no guarantee the tank is actually on this high-resolution image.>>

I can't even get myself to see those craters as craters and not bumps even though I know they're not bumps so I don't think I'll be able to find any fuel tanks. How many pixels could they be at 100% zoom? There is an unlabeled white object just to the northwest of the site. You can see it on the upper left corner of your image in this post, even. Anyway, I feel lucky I was even able to find the landing site on that enormous image.

After I downloaded the full image, I had to flip it 180° to get them to become innies instead of outies. But I still haven't found anything. And I'm supposed to be working! :roll:

Go back to work Rob, I've already located it:
