NASA Discovers Massive New Moon Crater

The update

NASA’s Lunar Reconnaissance Orbiter has discovered a 728-foot-wide crater on the Moon that formed sometime between April and May 2024. The crater, named McGetchin after pioneering lunar scientist Tom McGetchin, represents the largest newly formed crater ever identified in the solar system.

Why it matters

This discovery highlights the dynamic nature of the lunar surface and the value of NASA’s long-term lunar observations. The impact disturbed the surface for miles around, creating a surprisingly large cold zone. Unlike Earth, the Moon has no atmosphere to slow incoming space objects, making it more vulnerable to impacts. The finding demonstrates how even a single collision can dramatically reshape the lunar landscape.

What to watch

Scientists estimate an impact this large may occur on the Moon only about once every century. Researchers will continue monitoring the area and analyzing the impact’s effects on the lunar environment. The discovery may also inform future lunar missions and commercial activities as NASA works toward a sustained human presence on the Moon.
