A piece of discarded space hardware is barrelling toward the Moon at supersonic speed, and it’s set to make contact this August. According to a new analyst report highlighted by Gizmodo, a stray SpaceX Falcon 9 rocket stage will smash into the lunar surface at Mach 7, marking one of the most high-profile unintended space debris impacts in recent years.
What Stray SpaceX Rocket Is Heading for the Moon?
The rogue hardware in question is the second stage of a Falcon 9 rocket launched in 2015, which carried the Deep Space Climate Observatory (DSCOVR) satellite into orbit for NASA and the National Oceanic and Atmospheric Administration (NOAA).
After deploying DSCOVR, the rocket stage was left in a high, unstable orbit around Earth. Over the past 9 years, gravitational pulls from Earth and the Moon have shifted its path, sending it on a collision course with the lunar surface.
SpaceX did not design the stage to deorbit or dispose of it safely, a common practice for older launch vehicles that has since been updated in newer Falcon 9 missions.
How Fast Is the Moon Impact?
The rocket will hit the Moon at Mach 7, equivalent to roughly 5,300 miles per hour (8,500 kilometers per hour). For context, that’s more than 7 times the speed of sound at sea level.
This extreme speed means the impact will be far more forceful than a typical low-Earth orbit debris collision. The stage weighs roughly 4 tons, so it will carry massive kinetic energy on contact.
- Mach 7 speed: ~5,300 mph / 8,500 km/h
- Rocket stage weight: ~4 tons (8,818 lbs)
- Expected impact force: Equivalent to 3 tons of TNT (preliminary estimates)
When Will the SpaceX Rocket Crash Into the Moon?
Per the analyst report cited by Gizmodo, the impact is set to occur this August. While an exact date has not been widely publicized, tracking data shows the rocket’s orbit is decaying steadily toward the Moon.
Lunar impact experts note that minor gravitational shifts could adjust the exact timing by a few days, but the August window remains firm.
Will Earthlings See the Moon Crash?
Unfortunately, no. The rocket is on track to hit the far side of the Moon, which is never visible from Earth. Casual observers will not be able to see the impact with the naked eye or home telescopes.
However, NASA’s Lunar Reconnaissance Orbiter (LRO) may capture images of the impact crater after the fact, and radio telescopes could pick up faint signals from the collision.
Why Does This Unintended Moon Impact Matter?
This crash highlights the growing problem of space debris, even in regions beyond low-Earth orbit. The Moon is no longer a pristine, untouched body, as human-made objects have been hitting it for decades.
Scientists are actually eager to study the impact site. The collision will excavate lunar soil (regolith) from beneath the surface, giving researchers new insights into the Moon’s geological makeup.
It also serves as a wake-up call for space agencies and private companies to improve end-of-life disposal protocols for launch vehicles, to avoid cluttering the Moon with debris.
Have Human-Made Objects Hit the Moon Before?
Yes, this is far from the first time a human-made object has crashed into the Moon. Notable past impacts include:
- Apollo program Saturn V third stages, which were deliberately crashed into the Moon to test seismic equipment
- A 2022 Chinese rocket stage impact, which left a double crater on the lunar surface
- Multiple decommissioned satellites and probe stages from NASA, Roscosmos, and other space agencies
What Happens After the Crash?
The Falcon 9 stage will disintegrate on impact, leaving a crater roughly 10–20 meters wide, per preliminary estimates. The debris will be scattered across a small area of the lunar far side.
LRO teams plan to image the crater in the months following the impact, to measure its size and analyze the ejected regolith. This data will help improve models of high-speed impacts on airless bodies.
The August impact is a reminder that space activities have long-lasting effects, even on our nearest celestial neighbor. As private space companies ramp up launch cadence, managing debris will only become more critical.
