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]

Corrections
| 10/07/2026 | FAQ corrections: removed the question about earlier lunar impacts, which no listed source covers; the damage answer now uses NASA's estimate of a crater about 60 feet across and 12 feet deep and the reported impact site; the disposal answer now quotes SpaceX's statement instead of an unsourced paraphrase. | Applied |
Frequently asked
Did the impact damage anything?
No damage was caused other than a new crater, according to The Conversation. NASA estimated the impact would create a crater about 60 feet across and 12 feet deep; the stage struck terrain near Einstein Crater on August 5, 2026. Astronomers planned to observe the event because a crater made by an object of known size, shape and mass helps scientists understand the lunar surface.[1][2][3]
Why couldn't SpaceX prevent it?
SpaceX said: "For higher energy missions like those to a lunar transfer orbit, nearly all performance on the vehicle is devoted to successfully placing the payload in the intended orbit, and a controlled disposal manoeuvre is not always possible."[2]
