The crash location of a mysterious rocket body that struck the Moon’s surface earlier this year has been located by NASA. It wasn’t your typical rocket, as shown by the large double crater that was left behind after the hit.

However, since the strange projectile’s crash landing, none of Earth’s space-exploring governments have claimed ownership of it, leaving NASA experts perplexed as to who was responsible for its launch. The strange impact site is visible in new photographs released by NASA’s Lunar Reconnaissance Orbiter on June 24.

The crater is really two craters, with the eastern one being larger (18 meters in diameter, or 19.5 yards), and the western one being smaller (16 meters in diameter, or 17.5 yards). Unexpectedly, there was a twin crater. Double craters were not produced by any other rocket body impacts on the Moon.

After observing the mysterious rocket heading toward the Moon late last year, astronomers predicted the disaster. On March 4, it ultimately impacted close to the complex impact crater known as Hertzsprung on the far side of the Moon.

Although the craters may have been generated by the two huge masses on either end of the rocket, NASA remarked that the impact marks are extremely rare. NASA claims that spent rockets typically have a hefty motor at one end and a lighter empty fuel tank at the other. The space agency made no educated guesses as to the nature of the extra mass.

ASU data from 2016 shows that at least 47 NASA rocket bodies have caused spacecraft collisions on the moon. According to NASA, each of the overlapping craters produced by the March 4 impact is far smaller than the four sizable moon craters ascribed to the Apollo 13, 14, 15, and 17 missions. The new twin crater’s greatest breadth, according to experts, is comparable to that of the Apollo craters.
