A Falcon 9 rocket will hit the Moon this summer at seven times the speed of sound

SMRTR summary

A spent Falcon 9 rocket upper stage from a January 2025 lunar mission is on a collision course with the Moon, expected to impact on August 5 at 2:44 am ET. The 45-foot-tall piece of space debris will strike the lunar surface intact at seven times the speed of sound, since the Moon has no atmosphere to slow it down. The impact will likely be too faint to observe from Earth.
