South Korea's Danuri lunar orbiter has captured the first images of a fresh crater gouged into the Moon's surface by a stray SpaceX rocket stage, giving scientists a rare look at the immediate aftermath of an unintentional lunar impact.
The object was the upper stage of a Falcon 9 rocket launched in January 2025 to carry two lunar landers into space. After completing its mission, the spent stage drifted off course for roughly a year and a half before solar activity and gravitational pull nudged it onto a collision path with the Moon. It struck the surface on Wednesday at an estimated speed of about 8,700 kilometers per hour, or roughly 5,400 miles per hour, near the Einstein Crater on the lunar far side.
Operated by the Korea Aerospace Research Institute, Danuri made multiple passes over the site and photographed it using its high-resolution Lunar Terrain Imager camera, releasing the images on Thursday. The pictures show a patch of terrain noticeably darker than its surroundings, evidence of dust and pulverized rock thrown outward by the impact. Researchers compared the new images against earlier orbital photos of the same stretch of terrain to confirm the smudge, described in reporting from Phys.org as darker in some frames and lighter in others, was not present before the crash.
Unintended lunar impacts from spent rocket hardware are not new. Discarded stages and defunct spacecraft have struck the Moon before, and space agencies increasingly track such objects once their fuel is spent and they become uncontrollable. What made this case notable is the speed with which a dedicated lunar satellite was able to document the fresh scar, offering researchers real-world data on how orbital debris alters the surface, according to the Washington Post.
Danuri, which launched in 2022 to scout potential landing sites and search for water ice, was already orbiting the Moon when the impact occurred, allowing it to respond quickly. Scientists say the images will help refine models of how fast-moving debris interacts with the lunar surface as the number of missions, and discarded hardware, heading to the Moon continues to grow.
