Mare Spumans/ˈspjuːmənz/ (Latin spūmāns, the "foaming sea") is a lunar mare located just south of Mare Undarum on the lunar near side. It is one of the many elevated lakes contained in the Crisium basin, surrounding Mare Crisium. The surrounding basin material is of the Nectarianepoch, while the mare basalt being of the Upper Imbrian epoch. The craterPetit (formerly Apollonius W) is located on the western rim of the mare. This crater is white and surrounded by a well-defined ray system.
A small, bright-rayed crater located in northern Mare Spumans was known as landmark A-1/11 (1.7981° N, 65.0741° E). Astronaut Michael Collins tracked this landmark on revolution 4 of Apollo 11. Tracking the crater with a sextant and feeding the information into the onboard computer enhanced orbital information.[2] Collins referred to this crater as KAMP, after his three children and wife (Kate, Ann, Michael, and Patricia).[3]
