Kosmos 440

Kosmos 440 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 440 rather than just read about it. In short: Kosmos 440 (Russian: Космос 440 meaning Cosmos 440), also known as DS-P1-I No.10 was a satellite which was used as a radar target for anti-ballistic missile tests. It was launched by the Soviet Union in 1971 as part of the Dnepropetrovsk Sputnik programme.

Key takeaways

Kosmos 440 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 440 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kosmos 440 from memory before moving on to harder problems.

Reference excerpt

Kosmos 440 (Russian: Космос 440 meaning Cosmos 440), also known as DS-P1-I No.10 was a satellite which was used as a radar target for anti-ballistic missile tests. It was launched by the Soviet Union in 1971 as part of the Dnepropetrovsk Sputnik programme.

Launch It was launched aboard a Kosmos-2I 63SM rocket, from Site 133/1 at Plesetsk. The launch occurred at 10:30:00 UTC on 24 September 1971.

Orbit Kosmos 440 was placed into a low Earth orbit with a perigee of 272 kilometres (169 mi), an apogee of 788 kilometres (490 mi), 70.9 degrees of inclination, and an orbital period of 95.2 minutes. It decayed from orbit on 29 October 1972. Kosmos 440 was the eleventh of nineteen DS-P1-I satellites to be launched. Of these, all reached orbit successfully except the seventh.

Worked examples

Example 1 — a first encounter with Kosmos 440

Start with the simplest possible case. Write down what Kosmos 440 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 440 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 440 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 440

In research: Kosmos 440 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 440 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 440 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1971 in spaceflight, 1971 in the Soviet Union, Dnepropetrovsk Sputnik program, so understanding it makes those chapters shorter.
In everyday life: Look for Kosmos 440 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 440 in simple terms?

Why does Kosmos 440 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 440?

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.
