STS-61-E

STS-61-E is a biology 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 STS-61-E rather than just read about it. In short: STS-61-E was a NASA Space Shuttle mission planned to launch on 6 March 1986 using Columbia. It was canceled after the Challenger disaster.

Key takeaways

STS-61-E belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect STS-61-E to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of STS-61-E from memory before moving on to harder problems.

Reference excerpt

STS-61-E was a NASA Space Shuttle mission planned to launch on 6 March 1986 using Columbia. It was canceled after the Challenger disaster.

Crew

Backup crew

Mission objectives Columbia was to carry the ASTRO-1 observatory, which would be used to make astronomical observations including observations of Halley's Comet. ASTRO-1 consisted of three ultraviolet telescopes mounted on two Spacelab pallets, controlled by the Instrument Pointing System (IPS) which was first tested on STS-51-F. After the Challenger disaster, the flight was remanifested as STS-35 and several crew members were replaced. Both Richards and Leestma were reassigned to STS-28 while McBride left NASA in 1989. Vance D. Brand replaced McBride as the commander while Guy S. Gardner and John M. Lounge replaced Richards and Leestma, respectively.

Worked examples

Example 1 — a first encounter with STS-61-E

Start with the simplest possible case. Write down what STS-61-E claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 STS-61-E 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 STS-61-E 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 STS-61-E

In research: STS-61-E appears in biology 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 STS-61-E 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: STS-61-E is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cancelled Space Shuttle missions, so understanding it makes those chapters shorter.
In everyday life: Look for STS-61-E 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 STS-61-E in simple terms?

STS-61-E was a NASA Space Shuttle mission planned to launch on 6 March 1986 using Columbia. It was canceled after the Challenger disaster.

Why does STS-61-E matter?

Because it connects several biology 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 STS-61-E?

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.
