SpaceX rocket stage believed to hit the Moon
BBC··5 Aug
A stray SpaceX Falcon 9 upper stage is believed to have crashed into the Moon near the Einstein crater at about 5,400 mph on Wednesday. The empty stage launched in January 2025 with two lunar landers and drifted for about 18 months before impact. Nasa's Lunar Reconnaissance Orbiter is expected to photograph the site for before-and-after comparison.

What It Means For You
- Space and science followers can treat this as an accidental impact with known mass and speed, not a mystery object.
- Anyone tracking lunar missions can expect before-and-after crater images once Nasa's orbiter photographs the site.
- Future Moon travellers and engineers gain a real-world test of how debris and shaking behave near landing zones.
What's Happening
- An empty Falcon 9 upper stage is believed to have struck the Moon near the Einstein crater at about 5,400 mph on Wednesday.
- The stage launched from Florida in January 2025 carrying two lunar landers, then drifted in a looping Earth-Moon orbit for roughly 18 months.
- Larger observatories are analysing impact data, and Nasa's Lunar Reconnaissance Orbiter is expected to image the crash site for comparison.
Why A Known Rocket Crash Helps Lunar Science
- Most lunar impacts are poorly measured; a tracked booster with known mass and speed lets scientists test crater models.
- Debris range and ground shake data feed directly into designs for landers and future surface habitats.
- Human-made objects have hit the Moon since 1959, but accidental tracked impacts remain uncommon research opportunities.
