Did you know that the Moon quakes? During the Apollo missions, astronauts placed seismometers on the lunar surface that recorded thousands of vibrations from moonquakes. Though rare and weaker than powerful quakes on Earth, moonquakes can rumble on for hours — long enough to shift boulders, tip over structures, destabilize lunar landers, or interrupt surface operations. Today, scientists are using boulder samples collected by Apollo crews and high-resolution images from NASA’s Lunar Reconnaissance Orbiter to study how often these quakes strike and where they might happen next. This will help NASA prepare for future lunar missions, ensuring that when Artemis astronauts set foot at the Moon’s South Pole for the first time, landers, technology, and equipment on the lunar surface can be placed and protected with even greater confidence.
