Last (crater)

Last (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 Last (crater) rather than just read about it. In short: Last is a feature on Earth's Moon, a crater in the Hadley–Apennine region. Astronauts David Scott and James Irwin landed the Lunar Module Falcon on the northern edge of it in 1971, on the Apollo 15 mission.

Key takeaways

  • Last (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 Last (crater) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Last (crater) from memory before moving on to harder problems.

Reference excerpt

Last is a feature on Earth's Moon, a crater in the Hadley–Apennine region. Astronauts David Scott and James Irwin landed the Lunar Module Falcon on the northern edge of it in 1971, on the Apollo 15 mission. Last crater is located approximately 2 km east of Hadley Rille and approximately 1 km northwest of Index, the intended landing point. The name of the crater was formally adopted by the IAU in 1973.

Worked examples

Example 1 — a first encounter with Last (crater)

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

In research
Last (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 Last (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
Last (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ12 quadrangle, so understanding it makes those chapters shorter.
In everyday life
Look for Last (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.
