Out of control rocket crashing into the moon is China’s, not SpaceX’s

Astronomers initially misidentified an object crashing toward the moon as a SpaceX Falcon 9 rocket. However, after further analysis, it was corrected to be part of China's Long March 3C rocket from the Changa 5T1 mission. The misidentification was due to trajectory assumptions and brightness matching. The reanalysis showed the Chinese rocket's trajectory was more consistent with the observed path, leading to the conclusion that it is the likely candidate for the moon collision.

Explain the significance of the trajectory and timing in the misidentification of the object that was thought to be a SpaceX Falcon 9 rocket.

What was the purpose of the Changa 5T1 mission in relation to lunar exploration?
