2026 SpaceX Lunar Impact — A Falcon 9 Stage Hits the Moon
A spent SpaceX Falcon 9 upper stage from a January 2025 lunar lander launch unintentionally struck the Moon on Aug 5, 2026 at about 2.4 km/s, blasting a fresh crater later imaged from lunar orbit.
A predicted, uncontrolled arrival
The stage's fate was sealed in January 2025, when it dispatched two commercial lunar landers and was left without a disposal burn in a high orbit that repeatedly crossed the Moon's path. Trackers flagged the eventual collision months ahead, and on August 5, 2026 the roughly four-tonne stage came down at about 2.4 km/s.[1][2]
South Korea's Danuri orbiter photographed the aftermath — a fresh crater and rays of ejecta. The event sharpened a policy debate: as landers, orbiters, and eventually crewed bases accumulate on the Moon, uncontrolled impacts by leftover hardware shift from curiosity to genuine operational hazard, with unresolved liability questions under the Outer Space Treaty.[2][3]

Frequently asked
Was this the first rocket stage to hit the Moon?
No — a rocket body widely attributed to a Chinese Long March mission struck the Moon in March 2022 after a similar uncontrolled drift. But the 2026 event was the first confirmed lunar impact of a SpaceX stage and drew far more attention amid expanding lunar programs.
Did the impact damage anything?
No operating spacecraft or infrastructure was harmed; the stage hit an uninhabited area, leaving a crater estimated at roughly 18 meters wide. Scientists actually value such impacts as calibration events for studying the lunar surface.
Why couldn't SpaceX prevent it?
Stages that push payloads onto lunar trajectories often lack the leftover propellant or battery life for a controlled disposal burn. SpaceX says it deorbits second stages when possible, but Moon-bound missions are an exception.
