A SpaceX rocket is expected to collide with the Moon on August 5, after scientists discovered it was on an accidental collision course with the lunar satellite. The upper stage of a Falcon 9 rocket, which is about the size of a five-storey building and has a mass of at least 4,000kg, will impact the Moon's surface near the Einstein crater, creating a crater over 17m in diameter. The collision is not expected to be hazardous to Earth, but rather an opportunity for scientists to observe the impact site and collect data. Astronomers predict that the moment of impact will be "more impressive than any explosion on Earth" due to the Moon's lack of atmosphere.

Story summary
Here is a summary of the news story:
On August 5, 2026, a SpaceX rocket's second stage slammed into the Moon's surface, creating a new crater near the Einstein Crater. The rocket was launched in January 2025 as part of a mission to carry two lunar landers to the Moon. Due to a combination of solar activity and gravity, the rocket's trajectory changed over time, setting it on an inevitable collision course with the Moon.
The impact occurred at approximately 8,700 km/h (5,400 mph), creating a crater estimated to be roughly 3 tonnes in size, equivalent to a small school bus. While there was no visible flash due to the daylight on the lunar surface, orbiters will survey the ejected dust plume and take high-resolution before-and-after imagery of the newly formed crater.
Scientists are excited about this accidental collision because it provides them with a unique opportunity to study high-velocity cosmic impacts and gain insights that can help future missions.

"Nasa will continue to track the booster for training purposes, as well as later observe the impact site for scientific purposes."
SpaceX launched this specific Falcon 9 rocket as part of a US and Japanese mission to carry a pair of lunar landers and scientific equipment to the Moon last year.

But parts of the rocket are shed in space and remain there, stuck in orbit unless they eventually collide with another celestial body.

The SpaceX object will land near the Einstein crater, which is visible from the Earth and will be illuminated by sunlight, according to astronomer Bill Gray.

He predicts it will create a crater more than 17m (56ft) in diameter.

The impending collision - predicted to happen at about 02:35 EDT (06:35 GMT) on Wednesday - is expected to captivate astronomers, both amateur and professional.
"It's something really huge smashing into the Moon.

It's not remotely dangerous, we can just watch the show," says Dr Matt Bothwell, public astronomer at the University of Cambridge.
asserted
Bothwell → watch → Cambridge
"It's going to impact and it's going to send up a huge plume of dust, maybe 50km into the air or more, and that's going to spread sideways over time," Bothwell said.
asserted
Bothwell → go → time
Given the Moon's lack of atmosphere and far weaker gravitational pull, the moment of impact will be "more impressive than any [similar] explosion on Earth", Bothwell said.
asserted
Bothwell → give → Earth
Nothing will slow the object down, like the atmosphere would do here on Earth - and nothing will prevent the estimated million kilograms in debris from rocketing up into space.
asserted
nothing → slow → space
While the impact will probably not be visible from Earth with the naked eye, people with access to a sophisticated telescope may be able to see a flash radiating off the Moon's surface, Bothwell said.
uncertain
Bothwell → see → surface
More significant would be the educative potential of the impact, Bothwell noted.

Bothwell → note → impact
He said this moment would present a unique opportunity to study what happens when an object hits the Moon.

Scientists are therefore gearing up to watch the event closely.

Big telescopes in the Americas, plus Nasa's Lunar Reconnaissance Orbiter and South Korea's Danuri probe, will track the flash, plume and new crater, and a citizen‑science project is signing up keen amateurs to film the impact too.
asserted

By catching the dust plume in action, astronomers hope to turn this accidental crash into a useful experiment.

Watching how much material gets thrown up, how high it goes and how it falls back should sharpen their models of lunar impacts, and even give clues about what lies just beneath the surface at the impact site, where fresh subsurface material will be exposed for the first time.

Bothwell, the astronomer, also said the collision would provide a cautionary tale about the issue of ever-accumulating, human-made space clutter.
asserted

"I think more people should be more worried about space debris," Bothwell said.

Bothwell → think → debris
"Every single year we put more stuff in orbit.

Sometimes the satellites just collide, and they shatter into more pieces.

I think there's a worry about a runaway cascade, if we put so much stuff in orbit.

According to the European Space Agency (ESA), there are around 54,000 objects floating in space that measure larger than 10cm.
