Parsons (crater)

Parsons (crater) 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 Parsons (crater) rather than just read about it. In short: Parsons is an impact crater on the battered far side of the Moon. It is located to the west-northwest of the crater Krylov, and to the east of Moore.

Key takeaways

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

Reference excerpt

Parsons is an impact crater on the battered far side of the Moon. It is located to the west-northwest of the crater Krylov, and to the east of Moore. Parsons is roughly circular in shape and the rim has undergone some erosion. There is a smaller, cup-shaped crater laid across the southeastern rim, and small craterlets along the northeastern and western rim edges. The interior is relatively featureless, with a floor that is about half the diameter of the crater. The International Astronomical Union named this crater in 1972 after the rocket engineer and occultist Jack Parsons, an important participant at the Jet Propulsion Laboratory in Pasadena, California.

Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Parsons.

Worked examples

Example 1 — a first encounter with Parsons (crater)

Start with the simplest possible case. Write down what Parsons (crater) 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 Parsons (crater) 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 Parsons (crater) 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 Parsons (crater)

In research: Parsons (crater) 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 Parsons (crater) 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: Parsons (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ02 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Parsons (crater) 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.
