A SpaceX Falcon 9 upper stage crashed into the moon early this morning at about seven times the speed of sound, and lunar orbiters are now racing to capture imagery of the impact site.

What Happened

At approximately 2:35 a.m. EDT (0635 GMT) on Aug. 5, the Falcon 9 upper stage struck the moon's sunlit side at roughly 5,400 mph (8,690 kph), likely carving out a crater up to 89 feet (27 meters) wide, according to scientists' calculations.

The rocket body was not intended for this outcome. It launched two private lunar landers — Firefly Aerospace's Blue Ghost and ispace's Resilience — into a high, moon-crossing Earth orbit in January 2025. Because the upper stage used most of its fuel reaching that distant trajectory, it could not return to deorbit in Earth's atmosphere.

Instead, SpaceX performed a different disposal maneuver, as Julianna Scheiman, director of NASA science and Dragon programs at SpaceX, explained during an Aug. 3 press conference: "For high-energy missions, we need to perform a different maneuver to ensure the second stage itself is safe per the appropriate rules and regulations." But natural forces later intervened — "a mixture of solar activity and gravity forces have put it on a path towards the moon," she said.

NASA spokesperson Rob Garner told Space.com that NASA's Lunar Reconnaissance Orbiter and the ShadowCam instrument on the Korea Pathfinder Lunar Orbiter will look for opportunities to capture before-and-after imagery. Image availability depends on impact location, lighting conditions, and when each spacecraft's orbit next carries it over the area — which may take a few days.

Ground-based observations have already yielded results. Scientists at Lowell Observatory in Flagstaff, Arizona reported detecting a sodium and lithium gas plume from the impact, measuring tens of kilometers across and lasting 5 to 10 minutes after the crash, according to Carl Schmidt's remarks to Inside Outer Space.

Why It Matters

The unintended crash offers researchers a rare opportunity to study how artificial objects affect the lunar surface. NASA's Meteoroid Environments Office will attempt to image the impact with ground-based telescopes at Marshall Space Flight Center in Alabama, though officials caution that the flash and plume are expected to be faint and local weather could hinder observations.

Researchers led by Benjamin Fernando of Los Alamos National Laboratory wrote that such imagery would provide "an opportunity to test pipelines for measuring flash properties to locate impact events seismically, and to better understand the multi-modal hazards posed to future lunar infrastructure and astronauts from space debris impacting the moon."

The Bottom Line

As orbiters collect data over the coming days, scientists hope to gain new insight into how rocket bodies interact with the moon — knowledge that could inform safer practices for future lunar exploration.

The impact site remains under observation, and researchers say images of the crash, plume, and aftermath may be released soon.
