A Falcon 9 upper stage designated as 2025-010D is projected to impact the Moon at roughly 8,750 km/h, according to orbital data and physical simulations analyzed by astronomer Bill Grey. The anticipated collision on the visible side of the Moon offers researchers a rare opportunity to study an artificial impact in real time, test new localization methods, and prepare for upcoming lunar seismic experiments.
Tracking the Falcon 9 Booster Trajectory
The 12-meter-long, 4-metric-ton rocket body was abandoned in orbit after launching two private lunar landers in January 2025, according to tracking data compiled by Bill Grey. Lacking the fuel required to reenter Earth’s atmosphere or escape into deep space, the empty metal structure began a prolonged drift around our planet. Specialized physical simulators developed by researchers indicate that the hollow stage will not penetrate the lunar surface as deeply as a solid meteorite. Instead, the structure will crush upon impact at 08:35 Polish time, carving out a fresh 20-to-30-meter crater and lofting high-altitude lunar dust.
Observing the Lunar Impact and Dust Cloud
Professional and amateur astronomers have been called upon to monitor the event, which is expected to generate a distinct flash and a massive plume of debris. According to published research findings, “Possible observations during this event include a flash in the moment of impact and a cloud of ejected dust.” Capturing these transient phenomena requires high-speed recording cameras capable of logging rapid optical changes. Observers positioned on the Earth-facing side of the Moon will have a direct line of sight to record the precise mechanics of the crater-forming process.

Frequently Asked Questions
When will the Falcon 9 upper stage hit the Moon?
The impact is scheduled for 08:35 Polish time on the visible side of the Moon, according to trajectory projections.
What caused the rocket body to strike the Moon?
The 4-ton upper stage, labeled 2025-010D, was left stranded in Earth orbit after exhausting its fuel following a January 2025 launch that deployed two private lunar landers.
What kind of scientific equipment is needed to view the impact?
Researchers state that high-speed recording cameras are necessary to properly capture the initial impact flash and the subsequent cloud of ejected lunar dust.
