The upper stage of a SpaceX Falcon 9 rocket crashed into the surface of the Moon early on Wednesday, August 5, striking an area near the Einstein and Bell craters around 3:35 a.m.
Officials at NASA believe the collision formed an 18-meter crater on the lunar terrain, although the American space agency is still searching for satellite imagery to depict the impact.
Space Exploration Technologies Corp., known as SpaceX, is a private American aerospace manufacturer that operates the Falcon 9, a reusable rocket designed to deliver satellites and spacecraft into orbit. The second stage of the vehicle burns out after carrying payloads toward space before being left in orbit.
NASA and independent astronomers are monitoring the collision as a rare opportunity to study lunar geology and the behavior of space debris in vacuum conditions.
Booster impact and kinetic force
Experts estimated that the component weighed approximately four tons and struck the Moon at a velocity of 2.43 kilometers per second.
The kinetic energy released during the crash was sufficient to carve out a crater measuring roughly 20 to 30 meters in diameter and about 4 meters deep.
The force of the impact produced a visible plume of rock and debris. However, NASA confirmed that the lunar collision poses no physical danger to Earth.
Scientists compared the power of the collision to that of a meteoroid of similar size. Such natural impacts occur on the Moon approximately every six days because the satellite lacks a protective atmosphere to burn up incoming space rocks.
Apollo history and NASA statement
NASA Administrator Jared Isaacman posted on social media that the crash closely resembles impacts caused by natural meteoroids.
Isaacman said that sending rocket stages into the Moon has a decades long history dating back to the Apollo era. During that program, NASA intentionally directed spent booster stages into the lunar surface for scientific experiments and seismic research.
He added that natural meteoroids strike the lunar surface every hour, and that impacts comparable to this Falcon 9 upper stage occur naturally about once every six days.
Trajectory from the Blue Ghost mission
The discarded rocket component originally belonged to the second stage of a Falcon 9 rocket launched on January 15, 2025, during the commercial Blue Ghost 1 mission.
After completing its primary task of propelling lunar landing modules toward the Moon, the rocket stage remained in a chaotic orbit in deep space.
A combination of solar activity and gravitational forces eventually shifted the booster onto an unplanned collision course with the lunar surface.
While discarding rocket stages on the Moon was not specifically planned for this mission, space agencies accept the practice as a technical measure to prevent space junk from cluttering active operational orbits around Earth.
Scientific tracking and Artemis planning
Astronomers and scientists plan to collect detailed data on the impact site using ground-based telescopes and orbiting space probes.
NASA's Lunar Reconnaissance Orbiter probe and South Korea's ShadowCam instrument are scheduled to survey and map the collision site over the coming days.
The Lunar Reconnaissance Orbiter is a robotic spacecraft launched by NASA to map the lunar surface, while ShadowCam is an ultra-sensitive optical camera developed to image permanently shadowed regions near the lunar poles.
Researchers said observing the debris plume and examining the fresh crater will provide crucial insights into the chemical and physical composition of lunar soil.
NASA considers the gathered data essential for designing future lunar infrastructure under the Artemis Program. The Artemis initiative is a multi-nation spaceflight program led by NASA that aims to establish a sustainable human presence on the Moon.
