Kosmos 772

Kosmos 772 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 Kosmos 772 rather than just read about it. In short: Kosmos 772 (Russian: Космос 772 meaning Cosmos 772) was an uncrewed military Soyuz 7K-S test. It was an unsuccessful mission as only one transmitter worked.

Key takeaways

Kosmos 772 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Kosmos 772 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kosmos 772 from memory before moving on to harder problems.

Reference excerpt

Kosmos 772 (Russian: Космос 772 meaning Cosmos 772) was an uncrewed military Soyuz 7K-S test. It was an unsuccessful mission as only one transmitter worked. Only the 166 MHz frequency transmitter operated, all of the other normal Soyuz wavelengths transmitters failed. The experience from these flights were used in the development of the successor program Soyuz spacecraft the Soyuz 7K-ST.

Mission parameters Spacecraft: Soyuz 7K-S Mass: 6750 kg Crew: None Launched: September 29, 1975 Landed: October 3, 1975 4:10 UTC Perigee: 154 km Apogee: 245 km Inclination: 51.8 deg Duration: 3.99 days

Maneuver Summary 193 km X 270 km orbit to 195 km X 300 km orbit. Delta V: 8 m/s. 196 km X 300 km orbit to 196 km X 328 km orbit. Delta V: 8 m/s. Total Delta V: 16 m/s.

Worked examples

Example 1 — a first encounter with Kosmos 772

Start with the simplest possible case. Write down what Kosmos 772 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 Kosmos 772 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 Kosmos 772 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 Kosmos 772

In research: Kosmos 772 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 Kosmos 772 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: Kosmos 772 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1975 in the Soviet Union, Kosmos satellites, Soviet military spacecraft, so understanding it makes those chapters shorter.
In everyday life: Look for Kosmos 772 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 Kosmos 772 in simple terms?

Kosmos 772 (Russian: Космос 772 meaning Cosmos 772) was an uncrewed military Soyuz 7K-S test. It was an unsuccessful mission as only one transmitter worked.

Why does Kosmos 772 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 Kosmos 772?

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.
