Kosmos 36

Kosmos 36 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 36 rather than just read about it. In short: Kosmos 36 (Russian: Космос 36 meaning Cosmos 36), also known as DS-P1-Yu #1, was a satellite which was used for use in calibrating the Dnestr space surveillance and as a radar calibration target, for tests of anti-ballistic missiles. It was launched by the Soviet Union in 1964 as part of the Dnepropetrovsk Sputnik programme.

Key takeaways

Kosmos 36 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 36 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kosmos 36 from memory before moving on to harder problems.

Reference excerpt

Kosmos 36 (Russian: Космос 36 meaning Cosmos 36), also known as DS-P1-Yu #1, was a satellite which was used for use in calibrating the Dnestr space surveillance and as a radar calibration target, for tests of anti-ballistic missiles. It was launched by the Soviet Union in 1964 as part of the Dnepropetrovsk Sputnik programme. It was built by the Yuzhnoye Design Bureau. Kosmos 36 was launched using a Kosmos-2I 63S1 carrier rocket, which flew from Mayak-2 at Kapustin Yar. The launch occurred at 03:36 GMT on 30 July 1964. After separating from its carrier rocket, Kosmos 36 was in a low Earth orbit with a perigee of 261 kilometres (162 mi), an apogee of 477 kilometres (296 mi), 49.0° of inclination, and an orbital period of 91.9 minutes. It decayed from orbit on 28 February 1965. Kosmos 36 was the first of seventy nine DS-P1-Yu satellites to be launched, of which all but seven were successful. The next launch of a DS-P1-Yu satellite, the DS-P1-Yu #2 will be on 12 February 1965, failed due to a second stage malfunction.

Worked examples

Example 1 — a first encounter with Kosmos 36

Start with the simplest possible case. Write down what Kosmos 36 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 36 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 36 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 36

In research: Kosmos 36 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 36 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 36 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1964 in spaceflight, 1964 in the Soviet Union, Dnepropetrovsk Sputnik program, so understanding it makes those chapters shorter.
In everyday life: Look for Kosmos 36 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 36 in simple terms?

Why does Kosmos 36 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 36?

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.
