FLORIDA Aug 5, 2026 – In the early hours of Wednesday, August 5, 2026, a roughly four-metric-ton spent upper stage from a SpaceX Falcon 9 rocket struck the lunar surface near Einstein Crater on the Moon’s western limb.
The object, cataloged as 2025-010D, impacted at approximately 06:35 UTC (2:35 a.m. EDT) while traveling at about 5,400 mph (2.43 km/s). It originated from the January 15, 2025, Falcon 9 launch that carried Firefly Aerospace’s Blue Ghost Mission 1 and ispace’s Hakuto-R Mission 2 (Resilience) lunar landers under NASA’s Commercial Lunar Payload Services program. After deploying the payloads, the passivated upper stage—measuring about 45 feet (13.8 meters) long and 12 feet (3.7–4 meters) in diameter—remained in a highly elliptical Earth orbit. Over the following year and a half, gravitational forces and solar activity gradually altered its trajectory, placing it on an unavoidable collision course with the Moon.
NASA announced the impact later that day via an official post on X, stating: “In the early hours of Wednesday, Aug. 5, a portion of a @SpaceX rocket impacted on the Moon’s surface. In this video, we answer some of your questions.” The accompanying video, featuring a NASA spokesperson, addressed public inquiries including what the impact was, whether NASA deliberately planned it (it did not), and the scientific value of studying such an event.
Independent astronomer Bill Gray of Project Pluto first identified the trajectory months in advance through extensive optical observations. NASA’s Center for Near-Earth Object Studies later confirmed a 100% probability of impact. The collision was expected to create a new crater roughly 60 feet (about 18 meters) wide and 12 feet deep, while ejecting a plume of lunar dust and debris. The kinetic energy released was estimated as equivalent to roughly three tonnes of TNT.
Because the impact occurred on sunlit terrain near the lunar limb, no bright impact flash was readily observable from Earth. However, ground-based telescopes detected indirect evidence, including a stream of sodium (from lunar material) and lithium (likely from the rocket) observed shortly after the predicted time by facilities such as the European Southern Observatory’s Very Large Telescope.
NASA and international partners are treating the event as a rare, predictable artificial impact opportunity. Scientists plan to study crater formation, ejecta plumes, and dust dynamics. NASA’s Meteoroid Environments Office used ground-based telescopes in an attempt to observe the event in real time, while the Lunar Reconnaissance Orbiter and South Korea’s Korea Pathfinder Lunar Orbiter (with its ShadowCam instrument) are positioned to capture high-resolution before-and-after imagery of the site in the coming days, subject to lighting and orbital conditions.
The impact poses no danger to Earth or active lunar missions and is comparable in scale to the natural meteoroid strikes that occur regularly on the airless Moon. Similar accidental rocket-body impacts have happened before, including a Chinese Long March stage in 2022, while deliberate impacts (such as NASA’s LCROSS mission) have long been used for scientific study.
As commercial lunar activity increases, events like this underscore the importance of tracking objects in cislunar space and refining debris-mitigation practices. High-resolution images of the fresh crater are expected to provide valuable calibration data for impact models in the days and weeks ahead.
