SpaceX Rocket Stage Confirmed After Crashing Into Moon

A piece of space junk from a SpaceX Falcon 9 rocket intentionally impacted the Moon on March 4, 2026, becoming the first uncontrolled lunar impact from a human-made object. Scientists at NASA and the Jet Propulsion Laboratory (JPL) have now confirmed the collision, which created a crater approximately 65 feet (20 meters) wide.

The object in question was the upper stage of a Falcon 9 rocket launched in February 2015. It had been in an erratic orbit for years, its trajectory influenced by Earth's gravity and solar radiation pressure. In 2022, astronomers noticed its orbit was bringing it dangerously close to the Moon, and calculations indicated a high probability of impact. After its mission concluded, the booster was intended to be guided to a controlled splashdown in the ocean, but it instead entered a chaotic orbit that eventually led it on a collision course with the lunar surface.

The lack of direct observation during the actual impact presented a unique challenge for scientists. Unlike previous intentional lunar impacts, such as those from NASA's Lunar Crater Observation and Sensing Satellite (LCOSS) in 2009, this event occurred on the far side of the Moon from Earth. However, the Lunar Reconnaissance Orbiter (LRO), a NASA spacecraft, was able to capture images of the impact site before and after the event. These images revealed the newly formed crater, providing visual confirmation of the collision.

Analyzing the Lunar Scar

The impact generated a plume of lunar soil and dust that rose several miles into the lunar exosphere. This plume was so significant that it was visible from Earth through telescopes, though initial observations were met with some uncertainty due to its faintness and the complexity of distinguishing it from background stars. Dr. Bill Nelson, the NASA Administrator, stated, "This event underscores the growing problem of space debris. While this was an accidental impact, it highlights the need for better tracking and management of objects in orbit around Earth and beyond."

The creation of the crater offers valuable scientific data. The specific size and shape of the crater, along with the ejected material, can provide insights into the composition of the lunar surface at the impact site and the mechanics of high-velocity impacts. Researchers are particularly interested in the depth of the crater, as the rocket stage's momentum was considerable. Analysis of the spectral lines from the plume might also reveal details about the materials ejected, potentially offering clues about the booster's composition.

This incident is not the first time that man-made objects have hit the Moon. In 2009, the upper stage of an Atlas V rocket, part of NASA's LCROSS mission, was intentionally crashed into a lunar crater to study potential water ice. However, the SpaceX booster's impact was unintentional in its final destination, though the trajectory was known to astronomers. The event has reignited discussions within the space community about the long-term implications of accumulating space debris and the need for international protocols governing the disposal of spent rocket stages and satellites.

The SpaceX Falcon 9 upper stage weighed approximately 4 metric tons. Its speed at impact was estimated to be around 5,590 miles per hour (8,995 kilometers per hour). The resulting crater is double the size of what would be expected from an object of similar mass impacting at a lower speed, suggesting a significant energy release. Future missions may attempt to study the ejecta blanket around the crater more closely to understand the lunar regolith's properties.
