Moon Places #13: Mare Imbrium
Mare Imbrium
Description: Mare Imbrium, the Sea of Showers, is one of the largest lunar maria, spanning 1,123 kilometers in diameter, formed in a massive impact basin about 3.9 billion years ago and filled with basaltic lava. Its smooth plain is bordered by mountain ranges like the Apennines and Alps, with features like wrinkle ridges and rilles. The region hosts diverse geology, including young lava flows and impact craters, and was explored by Apollo 15. It provides crucial data on the Moon's impact and volcanic history.
How I Got My Name: "Mare Imbrium" means "Sea of Showers" in Latin, named by early astronomers who linked lunar features to earthly weather patterns.
Interesting Fact: Contains the Montes Apenninus; visited by Lunokhod 1 in 1970 and Apollo 15 in 1971. The rover traversed the area, and Apollo astronauts collected samples that dated the basin to 3.9 billion years, revealing the Late Heavy Bombardment period.
Location: Centered at 32.8° N, 15.6° W, 1123 km diameter.
