McCool Hill

McCool Hill 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 McCool Hill rather than just read about it. In short: McCool Hill is the tallest of the Columbia Hills in Gusev crater, Mars. It was named in honor of William C.

Key takeaways

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

Reference excerpt

McCool Hill is the tallest of the Columbia Hills in Gusev crater, Mars. It was named in honor of William C. McCool, an astronaut of the Space Shuttle Columbia during its final mission where it disintegrated during atmospheric reentry (see Space Shuttle Columbia disaster).

Spirit Rover The hill was to be Spirit rover's next target. She was expected to reach significant north-facing slopes on the hill in mid-April 2006, and spend her second winter on Mars there. However, on the way to the slopes on "McCool Hill" between outcrops nicknamed "Oberth" and "Korolev," Spirit ran into an impassable sandy area. To increase solar power output, Spirit's handlers redirected the rover to a closer north-facing slope in an area known as "Low Ridge" or "Low Ridge Haven," about 20 meters away from the rover's position on sol 802 (April 5, 2006). Spirit spent the rest of the Martian winter here, operating from a fixed position for long periods of time, attempting to observe very small changes that would not be noticeable otherwise because the rover was moving much more often. Mission directors were undecided on where to go in the spring, either to re-attempt the climb of McCool Hill, go back to Home Plate, or elsewhere. In the end they decided to go to Low Ridge Haven. Husband Hill was originally thought to be the highest of the Columbia Hills as seen from Columbia Memorial Station until surveying by Spirit updated elevation levels, placing McCool as the highest.

Worked examples

Example 1 — a first encounter with McCool Hill

Start with the simplest possible case. Write down what McCool Hill 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 McCool Hill 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 McCool Hill 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 McCool Hill

In research: McCool Hill 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 McCool Hill 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: McCool Hill is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aeolis quadrangle, Hills on Mars, so understanding it makes those chapters shorter.
In everyday life: Look for McCool Hill 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.

Frequently asked questions

What is McCool Hill in simple terms?

McCool Hill is the tallest of the Columbia Hills in Gusev crater, Mars. It was named in honor of William C.

Why does McCool Hill matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study McCool Hill?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
