What do we know about the newest crater on the moon?

This is the first recorded unintentional case of space junk hitting the moon.
The story so far: A leftover piece of a spacecraft flying through space reportedly hit the surface of the moon last Friday, creating a new crater that may be around 65 feet wide. The piece of space junk was earlier believed to be a SpaceX rocket, but was later said to be the third-stage booster of Chang'e 5-T1 – a lunar mission launched by the China National Space Administration in 2014. China, however, denied responsibility, saying that the booster in question had "safely entered the earth's atmosphere and was completely incinerated", news agency AFP reported. According to orbital calculations, the collision took place on March 4 at 5.55 p.m. IST on the far side of the moon. The object reportedly weighs around four tonnes and was racing towards the moon at a speed of 9,300 km an hour. The speed, trajectory, and time of impact were calculated using earth-based telescope observations.
American astronomer Bill Gray was the first to predict the collision. In January 2022, Gray had said that a booster from a SpaceX Falcon 9 rocket was likely to hit the moon after seven years of floating in space. Gray later corrected his prediction, saying that the space junk was part of a Chinese lunar mission and not from SpaceX.
Gray runs Project Pluto, a blog that tracks near-earth objects. Project Pluto also supplies astronomical software to amateur and professional astronomers. Gray is the creator of popular astronomy software called Guide.
The astronomer explained the process of ascertaining the date and time of the collision in a blog post on Project Pluto. He informed that the object was first spotted during an asteroid survey in 2015 and was believed to be a part of the Deep Space Climate Observatory (DSCOVR) satellite that was launched by SpaceX on Falcon 9 rocket on February 11, 2015.
Gray continued to track the object, and after analysing data that came in from nine different observatories in January 2022, he was able to improve the accuracy of the object’s trajectory and give a confident prediction of the date and time of the object’s collision with the surface of the moon.
The astronomer has also said that this is the first recorded unintentional case of space junk hitting the moon.
According to Gray, an email from Jon Giorgini of NASA’s Jet Propulsion Laboratory in California made him retrace the trajectory of DSCOVR, and it was seen that the SpaceX spacecraft did not go close to the moon. “It would be a little strange if the second stage went right past the moon, while DSCOVR was in another part of the sky. There's always some separation, but this was suspiciously large,” Gray wrote on his blog.

Former CM B.S. Yediyurappa had challenged the first information report registered on March 14, 2024, on the alleged incident that occurred on February 2, 2024, the chargesheet filed by the Criminal Investigation Department (CID), and the February 28, 2025, order of taking cognisance of offences afresh by the trial court.
