Mare Spumans

Mare Spumans is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Mare Spumans rather than just read about it. In short: Mare Spumans (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.

Key takeaways

Mare Spumans belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Mare Spumans to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Mare Spumans from memory before moving on to harder problems.

Reference excerpt

Mare Spumans (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 Nectarian epoch, while the mare basalt being of the Upper Imbrian epoch. The crater Petit (formerly Apollonius W) is located on the western rim of the mare. This crater is white and surrounded by a well-defined ray system.

Apollo Landmark 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. Collins referred to this crater as KAMP, after his three children and wife (Kate, Ann, Michael, and Patricia).

Worked examples

Example 1 — a first encounter with Mare Spumans

Start with the simplest possible case. Write down what Mare Spumans claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mare Spumans before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mare Spumans ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mare Spumans

In research: Mare Spumans appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Mare Spumans in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Mare Spumans is common in secondary-school and first-year university syllabi. It links to neighbouring topics Imbrian, LQ13 quadrangle, Maria on the Moon, so understanding it makes those chapters shorter.
In everyday life: Look for Mare Spumans outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
