X-15 Flight 87

X-15 Flight 87 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 X-15 Flight 87 rather than just read about it. In short: Flight 87 of the North American X-15 was a sub-orbital spaceflight conducted by NASA and the US Air Force on 27 June 1963. The X-15 was piloted by astronaut Robert A.

Key takeaways

X-15 Flight 87 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect X-15 Flight 87 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of X-15 Flight 87 from memory before moving on to harder problems.

Reference excerpt

Flight 87 of the North American X-15 was a sub-orbital spaceflight conducted by NASA and the US Air Force on 27 June 1963. The X-15 was piloted by astronaut Robert A. Rushworth to an altitude of 86.7 km (53.9 mi) surpassing the U.S. definition of space. The X-15 was NASA's first space vehicle (the Mercury capsule flew into space first, but the X-15 was airborne before Big Joe 1). The Flight landed at Edwards Air Force Base. With this Rushworth was qualifying for his astronaut wings.

Worked examples

Example 1 — a first encounter with X-15 Flight 87

Start with the simplest possible case. Write down what X-15 Flight 87 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 X-15 Flight 87 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 X-15 Flight 87 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 X-15 Flight 87

In research: X-15 Flight 87 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 X-15 Flight 87 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: X-15 Flight 87 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1963 in spaceflight, X-15 flights, so understanding it makes those chapters shorter.
In everyday life: Look for X-15 Flight 87 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.
