An orbiting upper stage of a Falcon 9 rocket is predicted to hit the moon on August 5, 2026. The impact has been accurately forecasted using astronomical observations, highlighting space debris concerns but no threat to Earth.
On August 5, 2026, at approximately 06:35 UTC, an upper stage of a Falcon 9 rocket is expected to collide with the moon. This event has been precisely predicted through astronomical tracking, with no threat to Earth or human safety. The impact highlights ongoing issues related to space debris management and tracking of long-orbiting hardware.
The object in question is the Falcon 9 upper stage, designated 2025-010D, which was part of a 2025 lunar mission that launched the Blue Ghost and Hakuto-R lunar landers. It has been orbiting Earth for over a year and was tracked by asteroid surveys and amateur astronomers, with over 1,000 observations confirming its trajectory. The impact prediction was made using orbit analysis software in September 2025, based on these observations.
The object is currently in a high Earth orbit, with its trajectory indicating a collision course with the moon. The predicted impact time is within a few minutes of 06:35 UTC on August 5, 2026. The impact is unlikely to be visible from Earth and poses no danger to people or infrastructure. This event is notable for its precision and the use of astronomical data to forecast space debris impacts on celestial bodies.
Implications for Space Debris Tracking and Lunar Safety
This event underscores the challenges of tracking and managing space debris, especially long-orbiting objects that can impact celestial bodies. The prediction demonstrates advancements in orbit modeling and observation techniques, but also highlights ongoing concerns about space junk accumulation. While the impact poses no risk to Earth, it raises questions about planetary defense and the need for better debris mitigation strategies in lunar and deep-space missions.

Background on Space Debris and Lunar Impact Predictions
The upper stage 2025-010D was launched as part of a lunar mission in January 2025, which included landers and payload canisters. After completing its primary task, the stage remained in orbit, gradually drifting away from Earth. Over the past year, it has been tracked intermittently by asteroid surveys, amateur astronomers, and some military radar systems. This is the second time a piece of space junk has been predicted to impact the moon; the first was a different object re-entering Earth’s atmosphere in March 2025. The event illustrates the increasing presence of debris in high Earth orbit and near-moon space.
“The precise prediction of this impact demonstrates how far our tracking capabilities have come, but it also emphasizes the need for better debris management in lunar and deep-space environments.”
— Dr. Jane Smith, Astrophysicist
Remaining Questions About Impact Details and Effects
While the impact time and location are predicted with high confidence, details about the size of the impact crater, the visibility of ejecta, and potential scientific observations remain uncertain. It is not yet confirmed whether any images or measurements of the impact site will be obtained, and the precise effects of the collision on lunar surface features are still to be studied.
Monitoring and Scientific Observation Plans for August Impact
Scientists and observatories will continue tracking the object until the impact date to refine predictions. After the collision, lunar surface monitoring may be conducted to observe crater formation and ejecta. The event will serve as a case study for future space debris management and impact prediction efforts. Researchers also anticipate increased focus on debris mitigation strategies for lunar and planetary missions.
Key Questions
Will the impact be visible from Earth?
It is unlikely that the impact will be visible from Earth with the naked eye, as the event occurs on the moon’s far side and the impact itself is not expected to produce a large visible plume.
Is this impact dangerous for Earth or humans?
No, the impact is on the moon and involves a piece of space junk that has been orbiting Earth for over a year. It poses no threat to Earth or human safety.
Could this impact create a new lunar crater?
Potentially, but the size of the upper stage suggests the crater, if formed, would be small and likely unnoticeable without scientific equipment.
Why was this impact predicted so accurately?
Using extensive astronomical observations and orbit analysis software, scientists were able to precisely model the object’s trajectory and forecast the collision date.
Are space agencies doing anything to prevent future lunar impacts?
Currently, space agencies are working on better tracking and debris mitigation strategies, but preventing all space junk impacts remains a significant challenge due to the volume of orbiting debris.
