A SpaceX rocket stage launched in January 2025 drifted for more than 18 months before slamming into the moon at 8,700 kilometers per hour, creating a crater dozens of meters wide — while more recent lunar launches send spent stages safely into orbit around the sun instead.

A nearly four-ton machine built on Earth ended an uncontrolled 18-month journey by crashing into the Moon on August 5, 2026.

It was the SpaceX Falcon 9 upper stage that launched Firefly Aerospace’s Blue Ghost Mission 1 and ispace’s Resilience lander on January 15, 2025. After deploying the two spacecraft to a high orbit crossing the Moon, the expendable stage was unable to perform the controlled atmospheric reentry that normally jettisons the Falcon 9’s upper stage.

Instead, it spent about 18 months and three weeks moving through lunar space. Repeated gravitational pushes and pressure much lower than sunlight changed its path until it impacted near Einstein Crater at a speed of about 2.43 kilometers per second, or 8,700 kilometers per hour.

There is one important limitation around the title number. The effect was confirmed by before-and-after orbital images, which show a new dark surface change at the expected location. The description of the tens of meters wide crater is still based mainly on pre-impact models. Published estimates ranged from a height of the teens to about 40 metres. The exact diameter measured from high-resolution images after the impact has not yet been published.

The launch created three very different endings

the NASA launch record The probe will launch at 1:11 a.m. ET from Kennedy Space Center’s Launch Complex 39A. The mission was called Ghost Riders in the Sky, and carried two commercial lunar landers sharing a single rocket.

Blue Ghost went on to successfully land at Mare Crisium on March 2, 2025 and completed its planned surface mission. Elasticity reached lunar orbit, but crashed while attempting to land on June 5. The Falcon 9 stage that sent the two spacecraft on their way followed a third path.

The reusable first stage returned to Earth shortly after launch. The upper stage was exhausted. By the time it had the power needed for long-distance deployment, it did not have the thrust margin needed for the kind of controlled burn that typically sends a Falcon 9 stage into the Earth’s atmosphere over an unpopulated area. It remained in a very long Earth orbit that extended as far as the Moon, and was designated 2025-010D.

“Drifting” does not mean moving without rules

The stage is often described as drifting. This is a useful shorthand for lack of control, but it may give the wrong picture. The missile body did not float aimlessly. It followed an orbit governed by the Earth, Moon, and Sun.

At the distance of the moon, this orbit was sensitive. Every nearby corridor could be remodeled. Sunlight also exerts a very small force on the broad, collapsing cylinder. The impact of solar radiation pressure is small from one moment to the next, however it builds up over many months and complicates efforts to predict the exact point of impact.

Independent orbiter Bill Gray explains the variable solution in his book Pluto project record for 2025-010 D. Observations gradually narrowed the reach beyond 06:34 UTC on August 5, near the moon’s western limb.

The identity of the object has also been verified rather than simply assumed. Researchers backdated its orbit until launch in January 2025, and compared its visible and near-infrared spectrum to known spacecraft materials. they Physical description edition Absorption features are found consistent with spacecraft thermal control layers and a variable brightness pattern consistent with an elongated rotating body. The combined orbit, spectrum and shape make the Falcon 9 attribution strong, although the study remains a preprint and not a peer-reviewed research paper.

The collision is confirmed by a force greater than its dimensions

The South Korean Danori lunar rover passed over the expected location shortly after the collision and obtained images showing a new dark mark. NASA’s Lunar Reconnaissance Orbiter also examined the area. Change before and after is the physical evidence that turns a highly certain expectation into a certain effect.

that Associated Press reports on Dhanori’s photos The impact speed is 5,400 miles per hour, or about 8,700 kilometers per hour. This is slow compared to many natural meteorites, which can strike the moon at tens of kilometers per second, but it is still enough to excavate a large amount of regolith.

What early public photos don’t yet provide is a clean ruler across the final hole. The new dark spot could include upturned regolith and ejecta beyond the crater rim. Its virtual width can also change with camera resolution, viewing angle, and lighting. The orbital scar is real. Exactly one hole diameter is not yet a noticeable result.

“Dozens of metres” is a typical range, not a tape measure reading

Before the collision, researchers published a coordinated study Monitoring plan and simulation study. One widely published calculation suggests that the potential crater is about 27 meters wide and about five meters deep. Other methods produced estimates closer to 17 or 18 metres, while the physical characterization team discussed a value closer to 40 metres.

This spread is not evidence that the accounts were negligent. It reflects inputs that cannot be known exactly. Estimates of the mass of the spent stage ranged from about 3,900 to 4,500 kilograms because no one had a definitive measurement of the remaining fuel. The angle and direction at impact were also important. A hollow cylinder arriving at its end will not transfer its energy to the Earth in the same way as a cylinder arriving from its side.

The goal is also important. Loose regolith, compacted materials, and exposed rock produce various patterns of excavation and extrusion. Models must simplify some of these conditions before surveying the actual site.

For this reason, this event has scientific value despite being unplanned. Researchers know the object’s approximate mass, composition, path, and speed much better than they typically know those properties of a natural impactor. When a crater measurement becomes available, it can test how well impact models describe a thin-walled rocket object striking lunar soil at relatively low speed.

A small scar can carry significant operational warning

On the scale of lunar geology, a crater a few tens of meters wide is considered insignificant. The Moon has absorbed billions of natural impacts, including collisions far more energetic than this one. There were no people or operating facilities near the site, and the event did not pose any danger to the ground.

The operational concern is different. The four-ton unattended object repeatedly crossed the region as more countries and companies positioned orbiters, communications relays, landers and eventually manned systems. The Moon does not have a dense atmosphere to remove abandoned devices. Objects on unstable lunar paths can remain difficult to track and can be redirected by encounters that are difficult to predict years in advance.

SpaceDaily was previously rebuilt An unusually complete CV for 2025-010DFrom its launch and spectroscopic identification until its expected arrival. This tracking work was impressive. It also underscores a key distinction: knowing where an abandoned phase will go does not mean putting it on a responsible disposal path.

Occasionally an accidental collision may produce useful science, but this usefulness should not become an excuse. Intentional lunar impacts are targeted, coordinated and monitored as missions. The uncontrolled phase is a being whose ultimate danger has been accepted before anyone knows exactly where it is going.

Eliminating heliocentrism removes the stage from the crowded corridor

For many low-Earth orbit missions, the preferred ending is re-entry into the atmosphere. The final burn lowers the stage into the atmosphere, where it disintegrates over a planned remote area. High-powered lunar missions can make this a difficult choice because almost all of the available performance is dedicated to the payload.

Another practical path is to get rid of heliocentrism. The stage receives enough energy to leave the Earth-Moon system and continue in orbit around the Sun. NASA has studied the guidelines required for this Getting rid of heliocentrism in the upper stageincluding routes that use a lunar flyby to achieve escape from Earth.

There is evidence that later mission planning moved in this direction. The Falcon 9 upper stage from the IM-2 lunar launch in February 2025, designated as 2025-038E, is inserted into a solar orbit rather than a long-term Earth orbit crossing the Moon. This is one of the later obvious lunar examples. Other deep space launch systems also plan to de-heliocentric in their spent stages.

This evidence supports a shift in practice, but it does not prove that every new moon launch now follows the same rule. Disposition depends on payload mass, injection requirements, launch geometry, and remaining propellant after separation. “Safely” is also relative. The solar orbit does not destroy the stage and does not guarantee that it cannot encounter another object. It brings the devices to a much larger size and sharply reduces their near-term exposure to the Earth, the Moon and spacecraft operating on the lunar surface.

So the lesson of 2025-010D is less dramatic than the collision and more useful. The missile completed its launch mission successfully. The failure to deal with the post-deployment process occurred as someone else’s future problem. As lunar traffic grows, disposal can no longer be a footnote after payload separation. It must be one of the paths that the mission is designed to achieve.
