Overview
- The roughly 4‑ton Falcon 9 upper stage launched in January 2025 struck the Moon on Aug. 5, 2026 near Einstein Crater at an estimated speed of about 8,700 km/h, producing a fresh crater and ejecta plume.
- South Korea’s Danuri orbiter captured before‑and‑after high‑resolution images showing darker terrain and a new crater and NASA’s Lunar Reconnaissance Orbiter is expected to image the site for finer measurements next week.
- Ground and space observatories, including ESO’s Very Large Telescope, recorded a transient plume with sodium lines and traces of lithium that researchers say are consistent with lunar soil gas and material from the rocket stage.
- SpaceX says the collision was unintentional and resulted from long‑term orbital perturbations such as solar radiation pressure and multi‑body gravity that made a controlled disposal manoeuvre infeasible for that mission profile.
- The incident gives scientists a near‑controlled test of impact and ejecta models and has renewed calls from experts for better cislunar situational awareness, tracking standards, and clearer disposal responsibilities as lunar traffic grows.
