What Happened to Falcon 9 Lunar Impact (Predicted 2026)?

The 'Falcon 9 Lunar Collision' refers to the predicted impact of a spent SpaceX Falcon 9 rocket upper stage with the Moon on August 5, 2026. This particular stage, identified as 2025-010D, was part of a mission launched on January 15, 2025, from NASA's Kennedy Space Center. Its primary objective was to deploy two commercial lunar landers: Firefly Aerospace's Blue Ghost Mission 1 and iSpace's HAKUTO-R M2 (Resilience). While Blue Ghost successfully landed in March 2025 and Resilience crashed in June 2025, the Falcon 9 upper stage did not perform a planned de-orbit burn to re-enter Earth's atmosphere.

Instead, the 13.8-meter-tall, roughly 4-ton rocket stage became trapped in a highly elliptical orbit around Earth, sometimes swinging beyond the Moon's orbit. Over many months, the subtle but persistent force of solar radiation pressure, combined with gravitational influences from Earth, the Moon, and the Sun, slowly altered its trajectory. This led to an unexpected collision course with the lunar surface. The impending impact was first predicted and extensively tracked by independent astronomer Bill Gray, creator of the Project Pluto software, who has been monitoring the object since its launch.

The predicted impact location is near the Einstein Crater, on the Moon's near side, though close to the limb as seen from Earth. The stage is expected to hit at a speed of approximately 8,700 kilometers per hour (5,400 miles per hour), or seven times the speed of sound. This event, while unplanned, presents a unique scientific opportunity. With no atmosphere to slow it down, the intact stage will create a new crater, ejecting regolith hundreds of meters high. NASA's Lunar Reconnaissance Orbiter (LRO) is expected to capture high-resolution images of the site before and after the event, allowing scientists to study freshly excavated material and high-speed impact dynamics, which is valuable for understanding lunar geology and supporting future Artemis missions.

This incident also draws attention to the growing issue of space debris, particularly in cis-lunar space, where objects are less consistently tracked than in low-Earth orbit. While the impact poses no danger to existing lunar missions or potential human presence, it underscores the need for more responsible disposal of space hardware. It's important to note that a similar event in 2022, initially misidentified as a Falcon 9 stage, was later confirmed to be the upper stage of a Chinese Long March 3C rocket.

As of May 12, 2026, the Falcon 9 upper stage (2025-010D) continues its trajectory towards the Moon, with the impact date and time remaining consistent. Astronomers and space agencies are preparing to observe the event, with the LRO poised to document the aftermath. SpaceX has reportedly begun implementing measures for more controlled disposal of upper stages in recent lunar missions, such as placing them into solar orbits, indicating a potential shift in practices prompted by such incidents.
