A discarded SpaceX rocket stage, left adrift in space for years, is now on a collision course with the Moon. The impact is expected to occur in early 2026, making it one of the few known cases of human-made space debris striking the lunar surface. The rocket part, which helped launch a satellite in 2015, has been tumbling through space ever since, its orbit slowly decaying under the gravitational pull of the Earth, Moon, and Sun.
A seven-year drift ends in a lunar crash
The upper stage of a Falcon 9 rocket, used by SpaceX to deliver a space weather satellite into orbit, has been tracked by astronomers since its mission ended. After completing its job, the stage was left in a chaotic orbit around Earth. Over time, its path became increasingly erratic, and now calculations show it will hit the far side of the Moon on March 4, 2026. The collision will occur at a speed of about 2.58 kilometers per second, carving a new crater into the lunar surface.
Why astronomers are watching closely
The rocket stage is not the first piece of space junk to hit the Moon, but it is the first accidental impact of a large object in recent years. Previously, spacecraft have been deliberately crashed into the Moon for scientific purposes, such as NASA's LCROSS mission in 2009. This time, no one is steering the rocket. It is simply following the laws of physics, and its destination happens to be the Moon. Astronomers have been monitoring the object closely, and they are eager to observe the impact, which could offer insights into how the Moon's surface reacts to such collisions.
Local people in the United States, where SpaceX is based, have shown keen interest in the event. For many, it is a reminder that space exploration leaves behind more than just footprints. The rocket stage, weighing about four tons, will be completely destroyed on impact, leaving no debris in orbit. But the crater it creates will remain for millions of years, a permanent mark of human activity on another world.
The significance of this event goes beyond the crash itself. It highlights the growing issue of space debris, which includes defunct satellites, spent rocket stages, and other fragments orbiting Earth. While most debris eventually falls back to Earth and burns up in the atmosphere, some objects, like this rocket stage, end up on trajectories that take them far from our planet. The Moon, with no atmosphere to slow objects down, is a particularly vulnerable target.
As the impact date approaches, astronomers around the world will be watching, not to prevent the crash, but to learn from it. The event offers a rare opportunity to study the effects of a high-speed impact on the lunar surface, and to refine models of how space debris behaves over long periods. For now, the rocket stage continues its silent journey, a piece of human history heading for a final, fiery meeting with the Moon.
