Apollo 16 Booster Impact Site Found (asu.edu)

NormalVisual writes: After decades of mystery, the lunar impact site for the Apollo 16 S-IVB third stage has finally been found. These boosters were directed to impact on the Moon beginning with Apollo 13 in order to allow scientists to learn more about the Moon's inner structure by measuring the effects of the collisions with lunar seismographs. Five boosters were directed into the Moon during the lunar missions, and the other four impact sites had already been found shortly after the missions themselves. The Apollo 16 booster had been difficult to find because of a loss of radio contact with the booster before the impact, and the actual impact location was 30 km away from the original estimate.

In my opinion, this is how the US leapfrogged the USSR to the moon. While the US was beat initially, they had a more coherent program that took longer. The USSR skipped many of the smaller milestones but had to made up for them later which delayed larger technological leaps.

Probably most interesting is the soil, be able to look at fresh soil that hasn't been exposed for millions of years.

A lunar rover can go to all these interesting places like landing sites, take a close up of what solar radiation does to materials over past 45 years. Unfortunately Mars Underground folks hijacked the space program setting most resources to bypass the Moon and go straight to Mars.

    Speaking of Apollo 13, the third stage impact was the only planned objective accomplished by that flight. Geologists were very interested to see how much the Moon shakes. They did alert the crew good data was measured by seismographs left by Apollo 11 and 12, though crew probably didn't give it that much thought as there were more pressing matters to deal with.

      The booster would be largely intact, but distorted like a crushed coke can.

      I don't think so. If you read TFA you would discover that this thin hollow aluminum shell is hitting the Moon at the relatively slow (as hyper-velocity cosmic impacts go) of 2.3 km/sec. This makes it almost twice as fast, with four times the kinetic energy per gram as the muzzle velocity of the famous .220 Swift hyper velocity round which was long the highest velocity production bullet in the world. When a bullet going this fast hits something hard (like the ground) it explodes into fragments.

      The impact energy is in fact 2.6 MJ/kg, compared to the energy needed to completely melt aluminum, heating from 0 K, which is only 1.0 MJ/kg. It is also just a bit less than the energy content of gun powder.

      The article does include this plainly inaccurate statement; "During the impact, much of the energy went into crushing the booster and only a shallow crater was formed." The slower delivery of energy to a larger area as the hollow shell smashed into the surface no doubt led to a shallow (and probably larger) crater, but the energy of this impact is a couple of orders of magnitude greater than the mechanical strength of aluminum, and so the effect of crushing the tank is negligible.
