Kosmos 2452

Kosmos 2452 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 2452 rather than just read about it. In short: Kosmos 2452 is a Russian military communications satellite. It was launched July 6, 2009, at 1:26 UTC.

Key takeaways

Kosmos 2452 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 2452 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kosmos 2452 from memory before moving on to harder problems.

Reference excerpt

Kosmos 2452 is a Russian military communications satellite. It was launched July 6, 2009, at 1:26 UTC. It was launched by a Rokot launch vehicle from the Plesetsk Cosmodrome to a 1,400 km circular orbit and a high inclination (~82 degrees). It was the second Strela 3M satellite and was launched with two other satellites. Strela-3M (also known as Rodnik-S) is an improved version of the Strela-3 military communications satellite. Satellites of this type record digital information and then forward the stored data when the satellite is in view of a receiving antenna. This approach is used for communications in remote area lacking more traditional ground-based communications channels.

Worked examples

Example 1 — a first encounter with Kosmos 2452

Start with the simplest possible case. Write down what Kosmos 2452 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 2452 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 2452 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 2452

In research: Kosmos 2452 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 2452 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 2452 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2009 in Russia, Communications satellites of Russia, Kosmos satellites, so understanding it makes those chapters shorter.
In everyday life: Look for Kosmos 2452 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.
