Overview
- A spent Falcon 9 second stage is predicted to strike the Moon near Einstein Crater at about 2:35 a.m. ET on Wednesday, Aug. 5, traveling roughly 5,400 mph and weighing about 4,000 kilograms.
- SpaceX says the impact was not planned and attributes the trajectory change to solar radiation and gravitational perturbations after the stage was left in a high, moon‑crossing orbit following a Jan. 15, 2025 lunar launch.
- South Korea’s Danuri orbiter will try to image the collision in real time and NASA’s Lunar Reconnaissance Orbiter will take before‑and‑after photos while coordinated ground‑based teams of amateurs and professionals will attempt to record any ejecta plume.
- Researchers predict a relatively small crater roughly 20–30 meters wide and a few meters deep and expect the initial flash to be brief and hard to see while a sunlight‑illuminated ejecta plume may be detectable by well‑equipped telescopes.
- The event highlights limits in current cislunar debris tracking and disposal practices and could push agencies and operators to adopt clearer rules and traffic‑management measures as lunar activity grows.
