Hey. I was using the moon mapper when I came across a very strange image. The closest thing i can think of is a lunar lander, and i can see what looks like tracks coming from it. I was just wondering if anyone else had seen something like it, or knew what it is.

Looks right. I don't think it's Apollo 14 or 17, based on other images.

ETA: What is the location?

That is Apollo 15.
Acrotar ran across the same picture (http://cosmoquest.org/forum/showthread.php?150147-What-caused-this-weird-feature) recently.

Hi all, I was just wondering whether the dark feature in the picture below is an indication of a newer, smaller crater within a much larger, older crater? Thanks for any help with this. 19551

If you're talking about the somewhat darker feature that's maybe 30% the height of the frame, in the middle vertically, and on the right side, that is the shadow of a very degraded crater. Next to it (to the left), it is slightly brighter, which is where the sun is hitting. In the thumbnail you posted (which on my screen is maybe 100 pixels tall unless you click on it), it is easier to see this as a crater than at full-resolution.

Is the lighter, seemingly elevated area surrounding the large crater in the attached image indicative of a younger crater that have not been worn down much yet or of an impactor with greater mass/velocity pushing more surface material out of the way?

Thanks.

Typically, the brighter ejecta is indicative of a relatively young crater, so, Option 1.
