STS-61-H

STS-61-H 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-H rather than just read about it. In short: STS-61-H was a NASA Space Shuttle mission planned to launch on 24 June 1986 using Columbia. However, it was canceled after the Challenger disaster.

Key takeaways

STS-61-H 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-H to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of STS-61-H from memory before moving on to harder problems.

Crew

Backup crew

Crew notes Before Buchli was assigned to STS-61-H, Norman E. Thagard was the potential Mission Specialist 3 for this flight.

Mission objectives The main task of the mission was to bring two commercial satellites into orbit – Palapa B3 and Westar-6S, and military communication satellite - Skynet-4A, The British Skynet and the Indonesian Palapa were supposed to be accompanied by an astronaut from the two countries. After the Challenger disaster, the deployment of commercial satellites by the Space Shuttle was stopped, and for several years no international astronauts were nominated. Thus, neither the British nor the Indonesian payload specialists got a second chance for a spaceflight. The NASA crew however stayed together and participated in a 56-hour-long simulated mission known as STS-61-M(T) in 1987. The crew finally flew on STS-29, with Anna L. Fisher being replaced by James P. Bagian. Skynet 4A was launched on 1 January 1990 with a Titan III, Westar-6S was renamed Galaxy-6 and launched on 12 October 1992 by an Ariane 44L. Palapa-B3 was renamed to Palapa B2P and was launched on 20 March 1987 with a Delta-3920.

Worked examples

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

Start with the simplest possible case. Write down what STS-61-H 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-H 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-H 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-H

In research: STS-61-H 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-H 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-H 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-H 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-H in simple terms?

STS-61-H was a NASA Space Shuttle mission planned to launch on 24 June 1986 using Columbia. However, it was canceled after the Challenger disaster.

Why does STS-61-H 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-H?

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.
