Mare Crisium March 30, 2021 12:09 AM

Mare Crisium (Sea of Crises) is one of the Moon's great "seas", a vast impact basin that later filled with lava. It formed from a collision between the Moon and an asteroid between 4.55 and 3.66 billion years ago. Its diameter is 345 miles, roughly the distance between Bridgeport and Dauphin Island.

 

Mare Crisium is visible to the human eye in near the Northeastern edge of the Moon. It is prominent in photographs. In this image, it is soon to be engulfed in the lunar night.

 

Mare Crisium will soon be visited by small unmanned landers as part of NASA's CLPS (Commercial Lunar Payload Services) program. A contract has been awarded to Firefly Aerospace for a 2023 landing.
