Lichtenberg (crater)

Lichtenberg (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 Lichtenberg (crater) rather than just read about it. In short: Lichtenberg is an isolated lunar impact crater located in the western part of the Oceanus Procellarum. The nearest crater of note is Briggs to the south.

Key takeaways

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

Reference excerpt

Lichtenberg is an isolated lunar impact crater located in the western part of the Oceanus Procellarum. The nearest crater of note is Briggs to the south. Lichtenberg has a small system of rays, a characteristic of Copernican Period craters. The rays extend to the north and west of the crater but not elsewhere. The remaining flanks of the surface about the crater exhibit the low albedo of the lunar mare, and several mare flows have overlaid the existing rays on the east and south sides of the crater. These are thus among the youngest deposits of basaltic lava on the Moon, and are believed to be less than 1 billion years in age based on high-resolution crater statistics of the thin superposed lava flow. The most recent lunar geologic map (2020) identifies the older mare next to Lichtenberg as being as Upper Imbrian. Lunar scientist Paul Spudis advocates an unmanned sample-return mission to the young mare to obtain an absolute radiometric date that would constrain the time period of the formation of the maria on the moon. The rim of this crater is circular and sharp-edged, with negligible wear. On the inner sides the loose material has slid to the base, forming a ring of scree about the interior floor. Both the rim and the interior floor exhibit a relatively high albedo, which is usually an indication of a younger crater that has not been darkened by space weathering. Lichtenberg overlies a larger, ring-shaped ghost crater to the northwest, which has a low central rise. This feature is covered by ray material. Lichtenberg has been noted in the past for occurrences of transient lunar phenomenon. These typically take the form of a temporary, red-hued patch.

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 Lichtenberg.

The following craters have been renamed by the IAU.

Worked examples

Example 1 — a first encounter with Lichtenberg (crater)

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

In research
Lichtenberg (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 Lichtenberg (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
Lichtenberg (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Georg Christoph Lichtenberg, Impact craters on the Moon, LQ03 quadrangle, so understanding it makes those chapters shorter.
In everyday life
Look for Lichtenberg (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.
