An Unexpected Cosmic Experiment
In the early hours of this Wednesday, August 5, 2026, the lunar surface will witness a unique event: the upper stage of a SpaceX Falcon 9 rocket will accidentally impact our natural satellite. The collision will occur at 06:35 GMT (03:35 Argentine time) near the Einstein Crater, on the near side of the Moon.
The piece, weighing approximately 4,000 kilograms and about 12 meters long, is traveling at 8,700 kilometers per hour, about seven times the speed of sound. Although the initial flash will be brief and faint, the ejected material could rise several kilometers and remain visible to telescopes in South and North America for several minutes.
Origin of the Rocket
The rocket was launched on January 15, 2025 from Florida, carrying two commercial lunar landers:
- Blue Ghost (by Firefly Aerospace): Achieved a successful soft landing in March 2025.
- Resilience (by Ispace): Failed to land safely months later.
After fulfilling its mission of propelling the modules, the upper stage was left without fuel, trapped in an unstable orbit. A combination of solar activity and gravitational forces ultimately altered its trajectory, putting it on a collision course with the Moon.

A Gift for Science and Exploration
For planetary geologists, this accidental collision represents an exceptional opportunity. By knowing precisely the size, speed, and impact point, the event becomes a controlled experiment.
According to experts such as Benjamín Fernando from Los Alamos National Laboratory and Paul Wiegert from Western University, studying this collision will allow scientists to:
- Calibrate computer models on crater formation.
- Understand the dispersion of lunar dust (regolith) in an atmosphere-less environment.
- Determine the risk that debris poses to future lunar bases and astronauts of NASA's Artemis program.
NASA confirmed there is no danger to Earth. The South Korean orbiter Danuri and NASA's Lunar Reconnaissance Orbiter will take images of the area before and after the event to analyze changes in the terrain. This event follows a similar precedent that occurred on March 4, 2022, involving a Chinese rocket.
The Space Debris Challenge
This event highlights a growing problem: the accumulation of space debris. Unlike Earth, the Moon has no atmosphere to protect its surface or disperse dust. The marks from the Apollo missions have remained intact for over 50 years.
Although this impact does not affect heritage sites, experts point out the urgent need to create an international regulatory framework to coordinate space traffic and protect the Moon before it becomes a destination saturated with orbital garbage.
