On August 5, a segment of a SpaceX Falcon 9 rocket collided with the lunar surface, marking the latest instance of human-made hardware impacting the moon. The debris, identified as an 8,800-pound upper-stage rocket, struck near the Einstein crater at an estimated speed of 5,400 mph.
South Korea’s lunar orbiter, Danuri, has provided some of the first visual evidence of the collision. According to the Korea Aerospace Research Institute (KARI), the orbiter conducted eight imaging sessions, beginning roughly 30 minutes before the impact. These images revealed clear alterations to the local terrain and visible traces of ejecta spread across the site.
The object, cataloged as 2025-010D, was tracked by independent astronomer Bill Gray, who utilized his Project Pluto software to predict the trajectory. Gray, who previously monitored a Chinese rocket stage that struck the moon in 2022, identified the object after it had been left in an uncontrolled orbit following a January 2025 mission. During that flight, the rocket had delivered a commercial lander from Firefly Aerospace to the moon.
SpaceX explained that the upper stage became stranded in an orbital limbo because it required additional thrust to reach the lunar trajectory, unlike typical missions where stages burn up in Earth’s atmosphere or fall into the ocean. The company stated it worked with NASA on disposal solutions, noting that while such impacts are rare, they can occur with objects in these specific orbits.
The collision was projected to carve out a crater approximately 60 feet wide and 12 feet deep, displacing a significant plume of lunar dust and rock. While the impact was not easily observable from Earth, NASA is currently attempting to verify the site using its own Lunar Reconnaissance Orbiter, which has been active since 2009. The agency noted that capturing imagery is complex, requiring precise alignment of lighting, orbital timing, and spacecraft positioning.
NASA Administrator Jared Isaacman, a close associate of Elon Musk, addressed the event on the social media platform X. He emphasized that such occurrences have a long history, dating back to the Apollo era when NASA intentionally crashed spent stages into the moon to conduct seismic research. Isaacman added that future lunar base plans will prioritize the use of reusable spacecraft to mitigate such debris.
The Falcon 9, a 230-foot-tall medium-lift vehicle, is currently the world’s most active rocket. While the upper stage is expendable, SpaceX maintains that its next-generation Starship rocket is designed with a reusable second stage, which the company claims will eventually limit the amount of human-made hardware left in orbit.
NASA has expressed interest in the data collected from this event, stating it will help scientists better understand the implications of artificial impacts on lunar exploration. The agency continues to monitor the lunar surface for further developments regarding the crash site.
The incident serves as a reminder of the challenges associated with space debris management. As commercial and governmental space activity increases, the tracking of spent hardware remains a critical task for astronomers and space agencies worldwide.
The Danuri orbiter’s successful capture of the impact site highlights the growing capabilities of international lunar missions. By documenting the aftermath, researchers hope to gain insights into the physical effects of high-velocity collisions on the moon’s regolith.
SpaceX reiterated its commitment to space safety, noting that it actively manages hardware disposal for complex missions. The company continues to operate the Falcon 9 from launch sites in Florida and California for various missions, including Starlink deployments and crewed flights to the International Space Station.
As of now, the scientific community awaits further analysis of the imagery provided by the Danuri mission to fully assess the impact’s geological footprint. The event remains a significant point of interest for both the aerospace industry and the broader astronomical community.
The 8,800-pound rocket hardware was expected to be traveling at about 5,400 mph at the time of the crash, which occurred near a feature known as the Einstein crater.

Earlier this week, a piece of a SpaceX rocket joined the ranks of space rocks and other wayward spacecraft that have slammed into the moon and become permanent fixtures of our celestial neighbor’s surface.
Predicated as early as April, the lunar crash had for months attracted considerable attention from astronomers and the general public eager to see how the collision would play out.
While the spectacle wasn’t exactly easy to spot from Earth, lunar orbiters and, perhaps, even other spacecraft were expected to be in position to at least document the aftermath.
Here’s a look at what the orbiter captured, and what could be next as NASA also hunts for the crash site.
Independent astronomer Bill Gray, who writes the widely used astronomy software Project Pluto, appears to be the first to calculate and predict the stage’s impact using ground telescope observations of the object, designated 2025-010D.
Orbiting high above Earth once every 26 days, the object was pulled uncontrollably toward the moon by a combination of solar activity and gravitational forces after exhausting all of its fuel, according to astronomers and SpaceX.
It was not an entire Falcon 9 rocket that made the impact, but just a 45-foot portion known as the upper or second-stage.
The first-stage (or lower-stage) that provided the initial burst of thrust at liftoff would have separated much earlier in the flight and returned to Earth for a controlled landing to be recovered, refurbished and reused by SpaceX for future launches.
But finding the location isn’t exactly easy, as it depends on “lighting, orbital timing and spacecraft position,” the agency said in a press release before the impact.
NASA added that it may take “several days to receive imagery” if any is even captured.
Standing 230 feet tall, the two-stage rocket is classified as a medium-lift launch vehicle capable of carrying about 50,000 pounds of cargo to orbit.
SpaceX concluded its post referencing Starship, its 400-foot rocket that is still being developed.
