Hadley Rille meteorite

Hadley Rille meteorite 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 Hadley Rille meteorite rather than just read about it. In short: The Hadley Rille meteorite was a meteorite discovered on the Moon at coordinates 26° 26' 0" N, 3° 39' 20" E, or Station 9A, during the Apollo 15 mission in 1971. It was the second meteorite to be discovered on a Solar System body other than the Earth.

Key takeaways

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

Reference excerpt

The Hadley Rille meteorite was a meteorite discovered on the Moon at coordinates 26° 26' 0" N, 3° 39' 20" E, or Station 9A, during the Apollo 15 mission in 1971. It was the second meteorite to be discovered on a Solar System body other than the Earth. The first was the Bench Crater meteorite, discovered in 1969 during the Apollo 12 mission.

Characteristics Within the soil sample 15602,29 collected near Hadley Rille was found an object in the 1–2 millimetres (0.039–0.079 in) size. The Hadley Rille meteorite massed about 3 milligrams (0.046 gr) and contained enstatite, kamacite, niningerite, silica, schreibersite, troilite, albite, and daubréelite. It is classed as an enstatite chondrite (EH) by the Meteoritical Society.

This photo was taken after the rake sample was collected. The Hadley Rille Meteorite was one of many samples collected with the rake from this location.

Worked examples

Example 1 — a first encounter with Hadley Rille meteorite

Start with the simplest possible case. Write down what Hadley Rille meteorite 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 Hadley Rille meteorite 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 Hadley Rille meteorite 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 Hadley Rille meteorite

In research
Hadley Rille meteorite 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 Hadley Rille meteorite 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
Hadley Rille meteorite is common in secondary-school and first-year university syllabi. It links to neighbouring topics Apollo 15, Chondrite meteorites, David Scott, so understanding it makes those chapters shorter.
In everyday life
Look for Hadley Rille meteorite 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.
