Mare Imbrium - Archimedes

Mare Imbrium (Latin for "Sea of Showers" or "Sea of Rains"), is a vast lunar mare filling a basin on Earth's Moon. One of the larger craters in the Solar System, Mare Imbrium was created when lava flooded the giant crater formed when a very large object hit the Moon long ago. Estimates of its age range from 3 billion to 4.5 billion years.

In 1971 the crewed Apollo 15 mission landed in the southeastern region of Mare Imbrium, near the Apennine Mountains.
