Quick Summary

NASA's Lunar Reconnaissance Orbiter discovered a massive crater on the moon, larger than the Roman Colosseum, which measures about 728 feet across and up to 141 feet deep. Formed by an asteroid or comet fragment two years ago, it is the largest impact crater created in recent times and occurs once every 132 years on average. The spacecraft first spotted the crater between April 11 and May 22, 2024, though detailed confirmation came early this year. This discovery highlights how impacts churn lunar soil more extensively than previously understood, potentially reshaping our understanding of the moon's surface evolution as NASA plans future missions there.

Story summary

NASA’s Lunar Reconnaissance Orbiter (LRO) discovered a massive crater on the moon's near side, larger than the Roman Colosseum, measuring about 728 feet across and up to 141 feet deep, in May 2024. The impact that formed this crater was caused by an asteroid or comet fragment roughly the size of a three- to six-story building. This event is estimated to occur only once every 132 years, making it a rare opportunity for researchers studying lunar geology and future moon missions. The crater was initially missed by Earth-based telescopes but spotted later in data analysis, providing valuable insights into the moon's surface changes as NASA plans to establish a base there.

Claims (21 extracted, 4 hedged)

Scientists have discovered a crater on the moon that's bigger than the Roman Colosseum and is the result of a powerful impact two years ago that initially went undetected. asserted
that → discover → impact
The steep-sided hole measured about 728 feet across, the length of two football fields, and up to 141 feet deep, equivalent to three vertically stacked yellow school buses, according to NASA. uncertain
hole → measure → NASA
It's the solar system's biggest known impact crater carved out in recent times. asserted
It → know → times
Such a large-scale event is estimated to occur only once every 132 years, researchers said, making this a treasure trove of information as NASA prepares to build a base for astronauts on the moon. asserted
NASA → estimate → moon
"This event constitutes a statistically rare, effectively once-in-a-lifetime observation," the scientists wrote in one of two studies appearing on the subject Wednesday in the journal Science Advances. asserted
scientists → constitute → journal
NASA's Lunar Reconnaissance Orbiter spotted the crater on the moon's near side sometime between April 11 and May 22, 2024, soon after it was formed when an incoming fragment of an asteroid or comet the size of a three- to six-story building hit the surface. uncertain
fragment → spot → surface
The moon strike escaped real-time detection by telescopes on Earth and in space. asserted
strike → escape → space
LRO's wide-angle images were not identified in the crush of data until August 2025. asserted
images → identify → August
The spacecraft gathered more detailed pictures last fall, followed by confirmation of the discovery early this year. asserted
spacecraft → gather → discovery
The crater — named for the late Thomas McGetchin, a former director of Houston's Lunar and Planetary Institute — is three times bigger than the previous record-holder found by the LRO a decade ago. asserted
crater → name → LRO
Pockmarked since ancient times, the moon bears some of the solar system's largest impact craters, including one that stretches more than 1,500 miles across. asserted
that → bear → one
This latest impact churned the lunar surface for more than 66 miles. asserted
impact → churn → miles
Dust and rocky soil were hurled away at a higher angle than expected, according to Mark Robinson, chief scientist for the LRO's cameras who works at Intuitive Machines. uncertain
who → hurl → Machines
A separate study identified a 4-mile-wide cold spot around the new crater, consistent with a loosening of the moon's top soil. asserted
study → identify → soil
Co-author David Paige of the University of California, Los Angeles, likens it to gardening. asserted
Paige → liken → gardening
"We're now thinking of impacts as a way to garden the regolith — churning the sediments and putting stuff above that's usually below the surface," Paige said in a statement. asserted
Paige → think → statement
NASA's has circled the moon since 2009, providing a close-up view of the lunar surface as the space agency prepares to send astronauts back. asserted
agency → circle → astronauts
The LRO's numerous crater discoveries since its launch show that the moon's top inch of soil is being overturned by ejected material every 80,000 years, faster than previously thought, according to Robinson. uncertain
inch → show → Robinson
Contrary to the popular belief that the Apollo moonwalkers' dusty lunar footprints will last forever, they will "definitely be long gone in that time frame," Robinson said in an email. asserted
Robinson → last → email
The next step is to calculate the risk of ejected crater material striking NASA's planned moon base, he added. asserted
he → calculate → base
"That information will help engineers harden structures so one won't have to worry about damage, or maybe worry less." asserted
one → help → damage
