Kosmos 862

Kosmos 862 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 862 rather than just read about it. In short: Kosmos 862 (Russian: Космос 862 meaning Cosmos 862) was a Soviet US-K missile early warning satellite which was launched in 1976 as part of the Soviet military's Oko programme. The satellite was designed to identify missile launches using optical telescopes and infrared sensors.

Key takeaways

Kosmos 862 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 862 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kosmos 862 from memory before moving on to harder problems.

Reference excerpt

Kosmos 862 (Russian: Космос 862 meaning Cosmos 862) was a Soviet US-K missile early warning satellite which was launched in 1976 as part of the Soviet military's Oko programme. The satellite was designed to identify missile launches using optical telescopes and infrared sensors.

Launch Kosmos 862 was launched from Site 43/4 at Plesetsk Cosmodrome in the Russian SSR. A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 09:12 UTC on 22 October 1976.

Orbit The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1976-105A. The United States Space Command assigned it the Satellite Catalog Number 9495. The satellite self-destructed on March 15, 1977, breaking into 13 pieces of which several are still on orbit.

Worked examples

Example 1 — a first encounter with Kosmos 862

Start with the simplest possible case. Write down what Kosmos 862 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 862 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 862 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 862

In research: Kosmos 862 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 862 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 862 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1976 in spaceflight, 1976 in the Soviet Union, Kosmos satellites, so understanding it makes those chapters shorter.
In everyday life: Look for Kosmos 862 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.
