Multiple outlets report that a roughly four-tonne (about 4 metric tons) section of a SpaceX Falcon 9 rocket struck the Moon on Wednesday, after an unintentional trajectory developed over months in space. The piece is described as the upper stage/second stage of a Falcon 9 that launched a lunar lander for Firefly Aerospace in January 2025. Reporting before confirmation indicated the impact was expected around 06:35 GMT (2:35 a.m. ET), at an estimated speed of about 5,400 mph (8,690 km/h). Several sources add that scientists expected telescopes to take time to confirm the impact, with imagery likely coming later after telescopes capture a debris plume and scientists analyze those observations.

SpaceX and scientists say the collision was not intended and does not pose a danger to Earth. Agencies expect the impact to create a new lunar crater, and the event could produce scientifically useful information about lunar material ejected by such collisions. Coverage also notes that the stage became uncontrolled after it was left in orbit, with analysts attributing its Moon-bound path to solar activity and gravity. NASA and SpaceX are said to be discussing ways to reduce the risk of future accidental impacts from leftover rocket hardware.
