The change cannot be seen with the naked eye, but it has implications for future NASA lunar missions: Researchers have discovered that the Moon is shrinking.
To be precise, the Moon loses about 45 meters of its circumference in a hundred million years. It doesn't sound like much, but this process causes moonquakes by cracking the Earth's crust and shifting tectonic plates. NASA scientists noticed the contraction when they were searching for potential landing sites in the moon's south polar region.
Landing sites are no longer an option due to moonquakes
Thomas R. says “Our model calculations suggest that shallow lunar earthquakes in the Antarctic region could trigger strong earthquakes,” said lead author of the study from the Center for Earth and Planetary Studies at the National Air and Space Museum. Landslides and faults remove some potential landing sites from the list. However, as NASA announced, the area is of particular interest for the construction of lunar stations due to suspected icy deposits. NASA wants to continue reducing the risk of moonquakes on the entire surface of the Moon by New seismic stations.
