SpaceX Falcon 9 Upper Stage Impacts Moon After Losing Control
A 4-tonne Falcon 9 upper stage unintentionally struck the lunar surface, creating a new crater; NASA says the impact poses no threat to Earth but highlights concerns about space debris.
A 4,000-kilogram upper stage of SpaceX's Falcon 9 rocket, launched in January 2025, collided with the Moon after exhausting its fuel and losing the ability to adjust its trajectory. The impact, estimated to have released energy comparable to three tons of TNT, generated a dust cloud and formed a new crater on the lunar surface.
Scientists had predicted the collision for early morning UK time and expected a brief flash, but amateur astronomers reported no visible flash from Earth. Images of the impact site are expected to be returned by lunar orbiters in the coming days.
"What has happened is essentially a mixture of solar activity and gravity forces have put it on a path toward the moon," Julianna Scheiman, SpaceX director of NASA science and Dragon programs, told reporters. NASA emphasized that the crash presents no danger to Earth.
Researchers see the event as an opportunity to study impact effects on the Moon, which could inform safety measures for future lunar habitats. However, experts also warned that the incident underscores the growing problem of space debris, which could threaten satellites and other assets.
"It may be of some — probably minor — scientific interest, and we may learn some things from it," said Bill Gray, developer of astronomy software. "It doesn't present any danger to anyone, though it does highlight a certain carelessness about how leftover space hardware is disposed of."
Space debris impacts on the Moon are uncommon; previous intentional impacts include NASA's 2009 and 1970s missions, while accidental crashes have involved Chinese, Russian, Indian and Israeli lunar probes. NASA and SpaceX are discussing measures to prevent future uncontrolled lunar impacts as the agency prepares for crewed missions under the Artemis program.
