description Mare Imbrium Basin Overview
Mare Imbrium Basin is a massive, ancient impact basin located on the Moon’s nearside. It represents one of the largest lunar maria, formed by a colossal collision event approximately 3.85 billion years ago. This vast expanse of basaltic lava flows makes it a significant area for scientific study regarding early solar system impacts and volcanic activity on the Moon. Geologists and planetary scientists investigate Mare Imbrium to understand the processes shaping our celestial neighbor.
help Mare Imbrium Basin FAQ
Where is the Mare Imbrium Basin located?
The Mare Imbrium Basin is a massive impact crater located on the nearside of Earth's Moon. It forms the right "eye" of the famous "Man in the Moon" face that is visible from Earth with the naked eye.
How old is the Mare Imbrium Basin?
Geological analysis of rocks brought back by the Apollo missions indicates the Mare Imbrium Basin was formed approximately 3.85 billion years ago. The impact occurred during the Late Heavy Bombardment period, a time when the inner solar system was frequently struck by massive asteroids.
What spacecraft have landed in the Mare Imbrium Basin?
In 1970, the Soviet Union's Luna 17 lander successfully delivered the Lunokhod 1 rover to the Sea of Rains, making it the first remote-controlled rover to explore another celestial body. China's Chang'e 3 lander and its Yutu rover also touched down in the northern part of the basin in 2013.
Why is the Mare Imbrium Basin filled with dark, flat rock?
Following the massive asteroid impact that carved out the basin, the crater filled with massive, basaltic lava flows roughly 3 to 4 billion years ago. When this ancient molten rock cooled, it formed the dark, relatively smooth plains that characterize the moon's "maria" (seas) today.
