Likely Crash Site of Mystery Space Junk Spotted on Moon’s Far Side - Gizmodo

Before-and-after images gathered by the Lunar Reconnaissance Orbiter (LRO) allowed scientists to spot two newly formed craters generated by the impact, which happened on March 4, according to a NASA press release.

NASA said the process could take weeks or even months to complete, which turned out to be the case, as the impact happened around four months ago.

The impact has unexpectedly formed two craters: an eastern crater measuring 59 feet (18 meters) wide and a partially overlaid western crater measuring 52.5 feet (16 meters) across.

As to the cause of the double crater, here’s what NASA had to say:.

The double crater was unexpected and may indicate that the rocket body had large masses at each end.

During the Apollo missions, the third stage of Saturn V rockets and second stage of Saturn IB launch vehicles (collectively known as S-IVB) were deliberately crashed into the Moon, forming oddly shaped craters.
