NASA's Lunar Reconnaissance Orbiter has identified a previously unknown impact crater on the Moon. NASA reported on September 16, 2026 that the feature was created by an impact in 2024 and was discovered while scientists were checking detailed lunar imagery.
How Large Is It?
The crater is about 222 meters (728 feet) across and up to 43 meters deep. NASA says it is one of the largest recent lunar impacts detected with this level of detail.
Why It Was Hard to Spot
The impact was not immediately noticed by Earth- or space-based telescopes. Scientists later compared high-resolution Lunar Reconnaissance Orbiter images and found the fresh disturbance in the Moon's surface.
What the Impact Tells Scientists
Fresh craters give researchers a way to study how quickly the lunar surface changes. The surrounding disturbed area also provides evidence about how impacts redistribute lunar soil and can help improve models used to protect future lunar infrastructure.
Why It Matters for Future Moon Bases
As planned lunar exploration moves toward longer stays, understanding the impact environment is increasingly important. Even rare events can affect equipment, surface operations and the way scientists interpret the age of lunar terrain.
