NASA | Counting Craters on the Moon

NASA scientists use the Lunar Reconnaissance Orbiter's Laser Altimeter to create a comprehensive catalog of large craters on the moon. By analyzing LOLA elevation data, they identify craters larger than 20 kilometers in diameter. The study reveals that in the moon's early history, there was a higher proportion of large impact craters compared to smaller ones, suggesting more significant impacts occurred. This research provides insights into the chaotic early days of the inner solar system, including Earth's history.
