In just a few months, the Moon is going to get hit by a piece of SpaceX hardware. On August 5 at 2:44 am ET, a Falcon 9 rocket’s upper stage will slam into the lunar surface at 5,400 mph, traveling at more than seven times the speed of sound. Bill Gray, who maintains Project Pluto software used by astronomers worldwide to track near-Earth objects, has calculated the precise moment of impact with high confidence.
The object in question is the second stage of a Falcon 9 that launched on January 15, 2025, carrying two lunar landers: Firefly’s Blue Ghost and ispace’s Hakuto-R. After deployment, the upper stage remained in orbit around Earth at a slightly higher altitude than planned, avoiding reentry. Over the past 14 months, astronomers have tracked it carefully, accumulating over 1,000 observations. The impact will likely occur in or near the Einstein Crater on the Moon’s near side.
Here’s the thing: nobody’s worried about this particular impact. The Moon is dead. There’s nothing there to damage except rocks and dust. Even if the timing or location was slightly off, the stakes would still be essentially zero.
But that’s not really the interesting part of this story.
The Problem That’s Just Beginning
Both NASA and China are actively planning semi-permanent outposts near the Moon’s South Pole. These aren’t small, one-off missions. They’re the foundation for sustained human presence on another world. That means launching rovers, supplies, habitats, communications equipment, and countless other payloads to support actual people living and working there.
Gray notes that the cadence of launches to the Moon is expected to increase by roughly a factor of 10 in the coming years. That’s not hyperbole. It’s a direct consequence of scaling from brief exploration missions to building infrastructure for long-term operations.
Now think about what happens when you multiply the number of launches by ten. You get ten times the debris. You get upper stages, fairings, and other hardware all cycling through lunar space. Some will miss. Some will hit. And when they hit a world where humans are establishing permanent facilities, the calculus changes entirely.
The Fix Is Simple, Actually
Here’s where it gets interesting: there’s an easy solution that already exists. With some extra planning and a relatively modest amount of fuel, launch companies can place these upper stages into disposal orbits around the Sun in paths that will never intersect with Earth or the Moon. No impact. No risk. Problem solved.
Gray makes the case that this should probably become standard operating procedure as lunar activity ramps up. It’s not a radical suggestion. It’s just common sense applied to orbital mechanics.
Yet it’s not happening yet. SpaceX didn’t do it with this Falcon 9 upper stage. Other launch providers haven’t made it standard either. The industry treats the Moon like it always has: as a place where impacts don’t matter because nothing important is there.
That assumption is about to expire.
When Assumptions Break Down
Four years ago, astronomers thought another Falcon 9 upper stage would hit the Moon, but subsequent analysis revealed it was actually from China’s Chang’e 5-T1 mission. This time, there’s no ambiguity. The object has been tracked continuously since launch in January 2025. The identification is certain.
What’s uncertain is whether this will be a wake-up call for the space industry. Will companies voluntarily adopt better disposal procedures? Will regulators require it? Will space agencies coordinate standards for lunar traffic management before it becomes a genuine safety hazard?
These aren’t rhetorical questions. They’re questions that will need answers fast, because the calendar is already moving and the Moon is about to get a lot busier.
