Goddard (crater)

Goddard (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 Goddard (crater) rather than just read about it. In short: Goddard is a lunar impact crater that is located along the eastern limb of the Moon, and so is visible from the edge from Earth. It is best viewed during favorable librations when the orientation of the Moon brings it further into sight.

Key takeaways

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

Reference excerpt

Goddard is a lunar impact crater that is located along the eastern limb of the Moon, and so is visible from the edge from Earth. It is best viewed during favorable librations when the orientation of the Moon brings it further into sight. The crater is located in the Mare Marginis, to the northeast of the prominent crater Neper. Ibn Yunus, a crater remnant, is attached to the southeastern rim and is partly overlaid by Goddard. To the northeast is Al-Biruni. The rim of Goddard has nearly been destroyed along the southern edge, and the interior floor is connected to the surrounding mare through gaps in this section of the wall. The remainder of the rim is significantly eroded and worn, leaving only a ring of rugged ground surrounding the inner floor. The floor of the crater has been resurfaced in the past by lava floods, leaving the interior nearly flat and featureless. There is no central peak, and only a few tiny craterlets mark the surface. The most prominent of these is a matched pair of small craterlets in the south-southwest part of the floor. This feature is named after the pioneering American rocket scientist Robert H. Goddard (1882–1945).

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 Goddard.

Worked examples

Example 1 — a first encounter with Goddard (crater)

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

In research: Goddard (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 Goddard (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: Goddard (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ13 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Goddard (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.
