Kosmos 1484

Kosmos 1484 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 1484 rather than just read about it. In short: Kosmos 1484 (Russian: Космос 1484 meaning Cosmos 1484), also known as Resurs-OE No.3-2 was a Soviet prototype Earth imaging satellite, launched in 1983 as part of the Resurs programme. It was a prototype of the Meteor-derived Resurs-O1 spacecraft, which paved the way for the first Resurs-O1 to fly in October 1985.

Key takeaways

Kosmos 1484 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 1484 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kosmos 1484 from memory before moving on to harder problems.

Reference excerpt

Kosmos 1484 (Russian: Космос 1484 meaning Cosmos 1484), also known as Resurs-OE No.3-2 was a Soviet prototype Earth imaging satellite, launched in 1983 as part of the Resurs programme. It was a prototype of the Meteor-derived Resurs-O1 spacecraft, which paved the way for the first Resurs-O1 to fly in October 1985. Kosmos 1484 was launched at 05:30:37 UTC on July 24, 1983. A Vostok-2M carrier rocket was used to place the satellite into low Earth orbit. The launch was conducted from Site 31/6 at the Baikonur Cosmodrome. Following the successful launch, the satellite was assigned its Kosmos designation, and was also given the International Designator 1983-075A, and the Satellite Catalog Number 14207. Following the completion of its mission, Kosmos 1484 remained in orbit for several years as [[space debris]|a derelict satellite]]. It suffered a fragmentation event - possibly due to a battery explosion - on October 18, 1993; however, the spacecraft remained relatively intact. Its orbit decayed and the main component of it reentered Earth's atmosphere on January 28, 2013. The American Meteor Society reported that its re-entry fireball was witnessed over the eastern United States, with sightings from New York state to Georgia. Most of the rest of Kosmos 1484 has also decayed but as of 2023, at least one fragment - 1983-075BG - remains.

Worked examples

Example 1 — a first encounter with Kosmos 1484

Start with the simplest possible case. Write down what Kosmos 1484 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 1484 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 1484 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 1484

In research: Kosmos 1484 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 1484 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 1484 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Kosmos satellites, Soviet spacecraft stubs, Spacecraft launched in 1983, so understanding it makes those chapters shorter.
In everyday life: Look for Kosmos 1484 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.
