Soyuz TM-18

Soyuz TM-18 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 Soyuz TM-18 rather than just read about it. In short: Soyuz TM-18 was launched from Baikonur Cosmodrome and landed 112 km north of Arkalyk. TM-18 was a two-day solo flight that docked with the Mir space station on January 10, 1994.

Key takeaways

Soyuz TM-18 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Soyuz TM-18 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Soyuz TM-18 from memory before moving on to harder problems.

Reference excerpt

Soyuz TM-18 was launched from Baikonur Cosmodrome and landed 112 km north of Arkalyk. TM-18 was a two-day solo flight that docked with the Mir space station on January 10, 1994. The three cosmonauts became the 15th resident crew on board Mir. The crew did research work in space flight medicine, primarily by cosmonaut Valeri Polyakov during his long-term flight, and accomplished 25 different experiments.

Crew

Mission highlights 18th expedition to Mir. Afanasyev and Usachev spent 179 days on Mir. Dr. Polyakov was slated to return to Earth on Soyuz-TM 20 in March 1995, after more than 420 days on Mir.

Worked examples

Example 1 — a first encounter with Soyuz TM-18

Start with the simplest possible case. Write down what Soyuz TM-18 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 Soyuz TM-18 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 Soyuz TM-18 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 Soyuz TM-18

In research: Soyuz TM-18 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 Soyuz TM-18 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: Soyuz TM-18 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Crewed Soyuz missions, Human spaceflights to Mir, Spacecraft launched in 1994, so understanding it makes those chapters shorter.
In everyday life: Look for Soyuz TM-18 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.
