The impact of a spent SpaceX Falcon 9 upper stage on the Moon has now been confirmed through multiple scientific observations, marking an important moment in lunar research. The rocket stage struck the lunar surface on August 5, 2026, near the Einstein crater region after remaining in space following its earlier mission.
Unlike the misleading AI-generated images and speculative posts that circulated online, scientists now have real evidence of the collision. South Korea's Danuri lunar orbiter captured before-and-after images of the impact region, while the European Southern Observatory's Very Large Telescope detected chemical signatures in the resulting impact plume. Read the latest report on Danuri's observations.
Together, these observations provide strong independent evidence that the Falcon 9 upper stage struck the Moon at its predicted location and created a new impact crater.

What Crashed Into the Moon?
The object was a spent upper stage of a SpaceX Falcon 9 rocket. The stage was associated with a January 2025 mission that launched Firefly Aerospace's Blue Ghost lunar lander and Japan's RESILIENCE lander.
After completing its primary mission, the upper stage remained in space rather than being deliberately disposed of. Its trajectory was later altered by gravitational and solar effects, eventually putting it on a collision course with the Moon.
Researchers had been tracking the object and predicted that it would strike the Moon in August 2026. A scientific study published before the impact estimated the collision would occur near the Einstein crater region. Read the scientific observational-planning study.
How Was the Moon Impact Confirmed?
The impact was not directly photographed at the exact moment of collision by a spacecraft positioned over the site. Instead, scientists combined orbital tracking, ground-based observations and later lunar-orbiter imaging to establish what happened.
The strongest visual confirmation came from South Korea's Danuri lunar orbiter. The spacecraft conducted multiple imaging sessions before and after the predicted impact, allowing researchers to compare the lunar surface and identify changes associated with the collision.
Space.com reported that Danuri captured before-and-after images of the new impact crater.
The observations showed a new crater and changes in the surrounding terrain, providing direct visual evidence that the predicted impact occurred.
Danuri Captures the New Lunar Crater
South Korea's Danuri, also known as the Korea Pathfinder Lunar Orbiter (KPLO), played an important role in confirming the event.
The spacecraft captured images of the target area before and after the impact. Researchers were therefore able to compare the lunar landscape and identify a newly created crater.
According to reports, the crater may be approximately 27 metres wide, although its final dimensions can be refined as scientists analyze the imagery in greater detail.
The crater is important because it provides physical evidence that can be compared with predictions about the impact energy, angle and properties of the rocket stage.
ESO Detects Material Released During the Collision
Visual images were not the only evidence available to scientists.
Astronomers using the European Southern Observatory's Very Large Telescope (VLT) in Chile observed the aftermath of the collision spectroscopically.
The observations detected chemical signatures associated with the impact plume, including:
- Sodium, believed to have originated primarily from the lunar surface.
- Lithium, believed to have originated at least partly from material associated with the rocket stage.
The chemical signatures remained detectable for only a short period, making the observations particularly valuable for researchers studying high-speed impacts on the Moon.
Reuters reported on the VLT observations and the detection of sodium and lithium.
Why Were Sodium and Lithium Important?
When a spacecraft crashes into the Moon at several kilometres per second, enormous amounts of energy are released almost instantly. Lunar soil and material from the spacecraft can be vaporised or blasted away from the impact site.
By examining the light from the resulting plume, astronomers can identify chemical elements within it.
In this case, the detection of sodium provides information about material released from the lunar surface, while lithium may provide clues about material associated with the spacecraft.
This type of spectroscopy allows scientists to study an impact even when a telescope cannot directly resolve the crater itself.
Why This Discovery Matters
The Falcon 9 impact is more than an unusual space event.
Every spacecraft impact on the Moon provides an opportunity to study how artificial objects interact with the lunar surface at high velocity.
The observations can help researchers improve models of:
- Impact crater formation
- Lunar ejecta and dust behaviour
- Impact plume chemistry
- Spacecraft material behaviour
- Lunar soil composition
- Artificial space-debris impacts
The event also highlights a growing issue for future lunar exploration: what happens to spacecraft and rocket stages after they complete their missions?
How Fast Did the Rocket Hit the Moon?
The Falcon 9 upper stage was travelling at approximately 5,400 miles per hour (8,700 km/h) when it struck the lunar surface.
That is roughly 2.4 kilometres per second, fast enough to release enormous kinetic energy when a several-tonne object collides with the Moon.
The Moon has essentially no atmosphere, meaning there was no thick atmospheric layer to slow the object before impact.
Where Did the Impact Occur?
The predicted impact location was near the Einstein crater region on the Moon.
Scientists had spent months tracking the Falcon 9 upper stage and refining its trajectory before the collision.
Pre-impact modelling suggested that the impact would provide a valuable opportunity to test techniques for locating artificial impacts and studying ejecta dynamics.
More Lunar Observations Are Coming
The scientific investigation is not finished.
Researchers are continuing to analyze the images and spectroscopic data collected around the event. Additional observations from lunar spacecraft can help refine the size, shape and surroundings of the newly created crater.
NASA's Lunar Reconnaissance Orbiter (LRO) is expected to provide additional observations of the impact area. LRO carries the Lunar Reconnaissance Orbiter Camera (LROC), which is capable of obtaining detailed images of the lunar surface.

Future analysis may provide:
- Higher-resolution images of the crater.
- More accurate crater-size measurements.
- Detailed mapping of surrounding ejecta.
- Additional information about the impact plume.
- Better estimates of the impact energy.
Why Accurate Information Matters
The incident also demonstrates why verified scientific evidence is important.
Before genuine images became available, numerous illustrations, simulations and AI-generated images of a supposed lunar crater circulated online. Some of these images were presented as though they were photographs of the actual impact.
They were not reliable evidence.
The newly available Danuri imagery and scientific observations provide a much stronger basis for discussing what actually happened.
Readers should therefore distinguish between:
- Actual spacecraft imagery
- Scientific observations
- Computer simulations
- Artist illustrations
- AI-generated images
Only the first two categories provide direct observational evidence of this event.
Frequently Asked Questions
