Heinlein (crater)

Heinlein (crater) is a earth 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 Heinlein (crater) rather than just read about it. In short: Heinlein is a crater in Promethei Terra, in the southeast end of the Hellas quadrangle of Mars. Centered at 65.2 degrees south, 114.64 degrees west, it is 85.34 km in diameter.

Key takeaways

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

Reference excerpt

Heinlein is a crater in Promethei Terra, in the southeast end of the Hellas quadrangle of Mars. Centered at 65.2 degrees south, 114.64 degrees west, it is 85.34 km in diameter. It is named after Robert A. Heinlein, a leading science fiction author. Heinlein helped to narrate the Moon landing with Walter Cronkite on CBS in 1969. He was involved in the planning of the Star Wars Defense program in the 1980s. Several of his novels involve Mars, especially Stranger in a Strange Land, Red Planet, Podkayne of Mars and Double Star. Many NASA officials say that his works inspired them to enter the space industry.

Worked examples

Example 1 — a first encounter with Heinlein (crater)

Start with the simplest possible case. Write down what Heinlein (crater) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth 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 Heinlein (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 Heinlein (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 Heinlein (crater)

In research: Heinlein (crater) appears in earth 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 Heinlein (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: Heinlein (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astrogeology stubs, Hellas quadrangle, Impact craters on Mars, so understanding it makes those chapters shorter.
In everyday life: Look for Heinlein (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.
