Thats the impact scar of the third stage of the Saturn V rocket (technically designated S-IVB) that carried Apollo 13 to but sadly, not on the Moon. Earlier missions had placed seismic instruments on the lunar surface to measure if the Moon had any activity. They found it did, and in fact several moonquakes were big enough that had you been standing there, you would have felt them quite strongly (and probably been knocked on your spacesuits backside).

Is the moon big enough to produce abiotic oil?
BTTT
The accepted theory is that the quakes are the result of tidal forces exerted on the Moon by the Earth.
“What causes the quakes? “
Impacts on the surface by foreign objects.
Cool.
When the Chinese get there they’ll take our flag down.
Ping.
And why not? They own it.
Green cheese is highly unstable.
Really interesting details on all of the Apollo Lunar Experiments here -

Nice shootin’, Doctor Von Braun. Thanks Free ThinkerNY.

A Celestial CollisionEarly in the evening of June 18, 1178, a group of men near Canterbury, England, stood admiring the sliver of a new moon hanging low in the west. In terms they later described to a monk who recorded their sighting, "Suddenly a flaming torch sprang from the moon, spewing fire, hot coals and sparks." In continuing their description of the event, they reported that "The moon writhed like a wounded snake and finally took on a blackish appearance"... [P]lanetary scientist Jack Hartung of the State University of New York... gathered enough clues to suggest that a large asteroid... might have smacked into the moon just over the horizon on the back side. To test his suspicion, Hartung went to the Lunar and Planetary Institute in Houston, and inspected Russian and American photographs of the moon's back side. Sure enough, in just the right place, he found a remarkably fresh crater, 12 miles across and twice as deep as the Grand Canyon. From it radiated white splatter marks for hundreds of miles... Such an impact, reason astrophysicists, would set the moon to ringing like a gong for thousands of years... At Texas' McDonald Observatory, astronomers Odile Calame and J. Derral Mulholland of the University of Texas find that the surface of the moon moves back and forth fully 80 feet! Such an oscillation clearly implies a collision with something large, sometime within the not-too-distant past, probably within the memory of mankind. The problem is that there is no way to peg the date exactly at 1178.

That’s fascinating. I assume the moon’s core is solid?
no, the core is not solid but the crust is a lot thicker then Earth.
