## Timeline

- **2026-08-05T02:35:00-05:00**: Rocket Stage Impacts Moon — The 4-ton stage slams into the lunar surface near Einstein Crater at 5,400 mph. No direct images are captured, but telescopes detect the resulting plume.
- **2026-08-05T02:35:00-05:00**: VLT Detects Plume for 5-10 Minutes — The Very Large Telescope captures spectral signatures of sodium (from lunar soil) and lithium (from the rocket) in the impact plume.
- **2026-08-05T07:28:00+01:00**: Falcon 9 stage impacts the Moon — The 4,000 kg rocket stage strikes near Einstein Crater at approximately 5,400 mph (8,690 km/h), generating a flash and dust plume.
- **2026-08-04T23:00:00-05:00**: Final Observations Confirm Collision Course — Retired astrophysicist Jonathan McDowell and other trackers report that the stage is heading straight for the Moon, with impact imminent.
- **2026-08-05**: Lunar Impact — The rocket stage crashes into the moon near Einstein Crater at 5,400 mph on the sunlit western limb.
- **2026-08-05**: Plume Detection — The Very Large Telescope in Chile observes a sodium and lithium plume lasting 5–10 minutes, confirming the impact.
- **2026-08-05**: SpaceX Acknowledgment — SpaceX’s Julianna Scheiman states the crash was accidental and that the company is working with NASA on future prevention.
- **2026-08-04**: Final Pre-Impact Observation — Astrophysicist Jonathan McDowell tracks the 4-ton upper stage on a direct collision course with the moon.
- **2026-04**: Impact trajectory identified — Astronomer Bill Gray publishes a report confirming that the derelict stage is on course to hit the Moon, based on months of tracking.
- **2025-01-15**: Launch of Lunar Lander Mission — SpaceX Falcon 9 lifts off from Kennedy Space Center carrying two lunar landers. The upper stage successfully deploys payloads but remains in an uncontrolled orbit.
- **2025-01**: Firefly Aerospace lunar lander launched — A SpaceX Falcon 9 rocket launches a lunar lander for Firefly Aerospace on a high-energy trajectory that leaves the second stage in space.
- **2025-01**: Falcon 9 Launches Firefly Lunar Lander — SpaceX launches a Falcon 9 rocket carrying a Firefly Aerospace lunar lander. After payload separation, the second stage is left in an unstable orbit around Earth.
