| Prehistoric Scratchpad|
By this time, all the lava flow in the Ocean had ceased in this ocean. The moon looked more or less the same as it does now from the naked eye. The moon was closer to the Earth though.
- 3.5 Billion years ago, the ocean was formed.
- The oldest lava flow in the area is estimated to be 1.2 Billion Years per crater counts.
- The Copernicus Crater was created in the middle of the sea about 800 Million Years ago.
- By the Warring States period, this ocean was identified as a Rabbit by the Chinese, and later the Japanese.
- In 1964, the impact probe Ranger 7 targeted this ocean after the conclusion of its picture-taking mission, and the sea landed in was named "Mare Cognito" (Known Sea).
- In 1966, Luna 9 landed southwest of Galilaei crater, Luna 13 southeast of Seleucus crater, and Surveyor 1 north of Flamsteed crater.
- In 1967, NASA's Surveyor 3 landed in Mare Cognito. Two years later, Apollo 12 landed at that same sight, called Statio Cognitum.
- In 1970, NASA cancelled Apollo 20, which might have explored Copernicus Crater.
