In March 2022, the space community and stargazers worldwide were captivated by an unexpected event: a mysterious rocket fragment slammed into the far side of the Moon, leaving behind a striking double crater. Early on, the guess was that SpaceX’s Falcon 9 might be responsible, fueling all sorts of speculation. But a recent scientific investigation has now set the record straight—and it’s not what most expected.

Was It SpaceX or China?
On March 4, 2022, astronomers detected a remarkable impact near the Moon’s Hertzsprung crater. The collision created a crater roughly 29 meters wide, characterized by its twin impact marks. Given the rise of SpaceX’s ambitious missions, many thought the culprit was a leftover Falcon 9 rocket stage from the 2015 DSCOVR mission. The idea that Elon Musk’s space ventures had literally left a mark on the Moon made for exciting headlines.
Yet, another candidate soon entered the scene: the third stage of China’s Long March 3C rocket, which was part of the Chang’e 5-T1 lunar mission. China’s growing presence in space added complexity to identifying the origin of the crash. Early assessments couldn’t decisively confirm if SpaceX or China was behind the impact, sparking lively debates across the global space community.
New Research Points to China
The mystery unraveled thanks to a meticulous study published in the Planetary Science Journal. Led by Tanner Campbell, a PhD candidate in mechanical and aerospace engineering at the University of Arizona, the team carefully analyzed the trajectory and reflective characteristics of the debris. Their conclusion? The impactor was almost certainly the Chinese Chang’e 5-T1 rocket stage.
“Our investigation involved tracking the object’s path and analyzing how light bounced off its surface,” Campbell explained. “The data aligned closely with the profile of the Chang’e 5-T1 stage, not any known SpaceX debris.” This finding was notable, especially since the Chinese space agency had earlier reported the rocket’s disintegration upon atmospheric re-entry.
Prior to impact, the Catalina Sky Survey, renowned for spotting near-Earth objects, tracked the fast-moving piece between Earth and the Moon. Initially designated WE0913A, its identity remained unclear until Campbell’s team compared its brightness and movement patterns against a massive database of space debris, ruling out SpaceX’s Falcon 9.
Interestingly, the object displayed a stable rotational pattern, unlike typical tumbling rocket parts. This suggested a unique structural design, possibly due to additional equipment onboard, which might explain the double crater pattern observed on the lunar surface.
Broader Implications for Space Exploration
This revelation not only clarifies the ownership of the lunar impact but also underscores how space is becoming a busy, contested arena with multiple nations launching complex missions. It highlights the growing need for international cooperation and transparency to avoid confusion or conflict in space.

While SpaceX has been a pioneer in democratizing access to space, China’s rapid advancements demonstrate that the race beyond Earth’s atmosphere is now truly global. The confirmation of Chang’e 5-T1’s role adds to China’s impressive track record and signals the country’s deepening capabilities in lunar and deep-space exploration.
For anyone fascinated by astronomy or aerospace engineering, the event serves as a vivid reminder: what happens on Earth—and by extension, human space activity—can leave lasting footprints far beyond our planet.
Looking to the Future
As humanity pushes further into the final frontier, lessons from this incident will be invaluable. Tracking space debris and openly sharing mission data are critical to ensuring safe and responsible space exploration.
The story of the “ownerless” rocket fragment crashing on the Moon symbolizes the dynamic, fast-evolving nature of space exploration today. It reminds us how scientific rigor and a spirit of discovery are essential to unmasking truths hidden in the vast cosmos.
With SpaceX and China both gearing up to push the boundaries of aerospace technology, from record-breaking orbital flights to establishing sustainable lunar bases, the future of space exploration promises to be as thrilling—and sometimes as surprising—as that fateful double crater on the Moon.
