A SpaceX Falcon 9 rocket upper stage is projected to collide with the Moon, according to independent astronomers and NASA tracking data. The impending lunar impact highlights growing concerns regarding space debris management as commercial lunar missions accelerate.
Falcon 9 Upper Stage Trajectory and Lunar Collision Course
The Falcon 9 rocket launched on January 15, 2025, carrying two commercial lunar landing modules: the Blue Ghost lander built by Texas-based Firefly Aerospace and the Resilience lander developed by Tokyo-based Ispace, according to mission records. While the Blue Ghost successfully landed on the Moon in March 2025, the Resilience lander failed to achieve a safe landing months later.
During the launch, the rocket’s first-stage booster returned to Earth, while the second-stage upper motor propelled the payloads toward the Moon. For low-Earth orbit missions like those near the International Space Station, SpaceX and other operators typically direct upper stages to burn up in Earth’s atmosphere, according to Julianna Scheiman, director of Ciência da Nasa e dos Programas Dragon da SpaceX. However, high-energy missions require a different disposal maneuver to comply with safety regulations. Scheiman stated in a Monday press briefing that solar activity and gravitational forces combined to push the Ispace and Blue Ghost upper stage onto a lunar impact trajectory.
Tracking Orbital Debris Beyond Earth
Independent astronomers used publicly available data to track the upper stage and identify its collision course, a finding confirmed by NASA’s Center for Near Earth Object Studies. Telescopes across the Americas targeted the Moon ahead of the predicted impact time of 2:35 a.m. Eastern time on Wednesday, with images expected to be released following the event.
Unlike Earth, the Moon lacks a protective atmosphere to disintegrate space debris. Furthermore, no formal tracking system exists for debris beyond Earth's orbit, leaving asteroid-hunting surveys to spot errant rocket fragments and hardware.
Implications for Future Artemis Infrastructure and Lunar Safety
As NASA advances the Artemis program to establish a permanent human presence on the Moon, managing orbital debris becomes increasingly critical. The Falcon 9 upper stage collision is expected to eject rocky material up to 805 kilometers (500 miles) from the impact site and carve out a crater measuring 20 to 30 meters (65 to 90 feet) in diameter, based on scientific estimates.
Wiegert warned that objects traveling at high velocities resemble bullets and pose significant threats to future astronauts, habitats, and equipment operating within lunar landing zones. To mitigate these risks, researchers and agencies are evaluating safer disposal pathways for high-energy missions operating within the Sun-Earth-Moon system. Observational assets including South Korea’s Pathfinder lunar orbiter and NASA’s Lunar Reconnaissance Orbiter plan to image the upper stage before impact and map the resulting crater afterward.
Did you know? While natural meteoroids frequently strike the lunar surface—generating flashes visible to Apollo and Artemis astronauts—collisions involving artificial spacecraft components have only occurred a handful of times in history.
Frequently Asked Questions
Can the public watch the Falcon 9 upper stage impact live?
No, direct live broadcasts of the impact are unavailable, but researchers expect telescopic images and mapping data to be released by space agencies following the event.
How big will the impact crater be?
Scientists estimate the collision will produce a crater measuring between 20 and 30 meters (65 to 90 feet) in diameter.
Which spacecraft are observing the impact site?
South Korea’s Pathfinder lunar orbiter attempted to capture images of the upper stage prior to impact, and NASA’s Lunar Reconnaissance Orbiter plans to map the resulting crater.
