A decades old mystery is now solved! After many attempts searching through Lunar Reconnaissance Orbiter Camera (LROC) images, the Apollo 16 S-IVB rocket booster impact site has been identified. During the Apollo exploration of the Moon, beginning with Apollo 13, the massive, upper stage (known as the S-IVB stage) that helped propel astronauts to the Moon, were directed to impact the Moon. The energy from these impacts was measured by seismometers left on the surface (by previous Apollo astronauts) to understand the internal structure of the Moon. [...] In the case of Apollo 16, radio contact with the booster was lost before the impact and thus the impact location was only poorly known.
