Researchers used thousands of images taken by the Lunar Reconnaissance Orbiter (LRO) and found at least 222 new impact craters. In earlier work, scientists took LRO imagery and compared them to old Apollo photos and found new craters. For this work, they identified over 14,000 LRO images that were taken under similar lighting conditions but at different times, and by comparing these images they found hundreds of new craters spread randomly across the surface.
There are more fresh craters measuring at least 10 metres across than standard cratering calculations would suggest. This could mean that some young lunar surfaces may be even younger than thought, says Daubar. She calls the work "a significant advance in the field of crater chronology", noting that it can even be used to compare cratering rates on the Moon and Mars.
From the paper's Editor's Summary:
Emerson Speyerer and co-authors use 14,092 temporal ('before and after') image pairs obtained by NASA's Lunar Reconnaissance Orbiter to quantify the contemporary crater-production rate on the Moon. They identify broad reflectance zones associated with the new craters that they interpret as evidence of a surface-bound jetting process, and estimate that this secondary cratering process is churning the top of the regolith much faster than previously thought.

You're making the untested assumption that the craters are created by impacts from space rather than by activities of the underground inhabitants.
The people who rely on government handouts and refuse to work should be kicked out of congress.

No! it is electro-static discharges that create craters on the moon! Do not let the fact that these have never been observed keep you from believing in the truth! There is a least as much evidence for the Electric Universe theory as there is for underground inhabitants in the moon.

There is clear documentation that super-sayan fights result in hundreds of craters. Calling Occam's razor on your electric universe.

I was eating a hard boiled egg earlier and came up with another possible cratering mechanism. If you have ever eaten one you know there is usually an impression somewhere due to the egg congealing against an air pocket. It reminded me of the one huge crater on iapetus* that makes it look like a death star. Also, sometimes the airpocket can move around and cause dimples over parts of the egg.
This got me thinking that if a moon/planet was covered in a "shell" at some point with a fluid underneath, then the "shell" is removed, it would result in craters. I would guess the shell would be ice and evaporate either slowly or due to a heating event. Or it could be from long ago during the time of planetary formation. The shell would be a layer of solid rock over a molten layer that slowly cools, then expands, and bursts off the shell.
