You've heard of earthquakes, now get ready for moonquakes! 🫨 Researchers using LRO data and rocks collected by Apollo 17 astronauts have developed a method to estimate the frequency of moonquakes along possibly active faults. Moonquakes are much rarer and weaker than earthquakes, but can last for hours. Understanding the Moon's fault lines and quakes will be important as the NASA Artemis program prepares to send astronauts back to the Moon. | NASA’s Goddard Space Flight Center
