Kosmos 1629

Kosmos 1629 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 1629 rather than just read about it. In short: Kosmos 1629 (Russian: Космос 1629 meaning Cosmos 1629) is a Soviet US-KS missile early warning satellite which was launched in 1985 as part of the Oko programme. The satellite is designed to identify missile launches using optical telescopes and infrared sensors.

Key takeaways

Kosmos 1629 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 1629 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kosmos 1629 from memory before moving on to harder problems.

Reference excerpt

Kosmos 1629 (Russian: Космос 1629 meaning Cosmos 1629) is a Soviet US-KS missile early warning satellite which was launched in 1985 as part of the Oko programme. The satellite is designed to identify missile launches using optical telescopes and infrared sensors. Kosmos 1629 was launched from Site 200/39 at Baikonur Cosmodrome in the Kazakh SSR. A Proton-K carrier rocket with a DM upper stage was used to perform the launch, which took place at 07:57 UTC on 21 February 1985. The launch successfully placed the satellite into geostationary orbit. It subsequently received its Kosmos designation, and the international designator 1985-016A. The United States Space Command assigned it the Satellite Catalog Number 15574. It was operational for about 2 years.

Worked examples

Example 1 — a first encounter with Kosmos 1629

Start with the simplest possible case. Write down what Kosmos 1629 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 1629 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 1629 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 1629

In research: Kosmos 1629 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 1629 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 1629 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1985 in spaceflight, 1985 in the Soviet Union, Kosmos satellites, so understanding it makes those chapters shorter.
In everyday life: Look for Kosmos 1629 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.
