Kosmos 601

Kosmos 601 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 601 rather than just read about it. In short: Kosmos 601 (Russian: Космос 601 meaning Cosmos 601), known before launch as DS-P1-Yu No.60, was a Soviet satellite which was launched in 1973 as part of the Dnepropetrovsk Sputnik programme. It was a 400-kilogram (880 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and was used as a radar calibration target for anti-ballistic missile tests.

Key takeaways

Kosmos 601 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 601 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kosmos 601 from memory before moving on to harder problems.

Reference excerpt

Kosmos 601 (Russian: Космос 601 meaning Cosmos 601), known before launch as DS-P1-Yu No.60, was a Soviet satellite which was launched in 1973 as part of the Dnepropetrovsk Sputnik programme. It was a 400-kilogram (880 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and was used as a radar calibration target for anti-ballistic missile tests.

Launch Kosmos 601 was successfully launched into low Earth orbit at 14:00:01 UTC on 16 October 1973. The launch took place from Site 133/1 at the Plesetsk Cosmodrome, and used a Kosmos-2I 63SM carrier rocket.

Orbit Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1973-075A. The North American Aerospace Defense Command assigned it the catalogue number 06875. Kosmos 601 was the sixty-fifth of seventy nine DS-P1-Yu satellites to be launched, and the fifty-ninth of seventy two to successfully reach orbit. It was operated in an orbit with a perigee of 197 kilometres (122 mi), an apogee of 1,404 kilometres (872 mi), 81.8 degrees of inclination, and an orbital period of 100.9 minutes. It remained in orbit until it decayed and reentered the atmosphere on 15 August 1974.

Worked examples

Example 1 — a first encounter with Kosmos 601

Start with the simplest possible case. Write down what Kosmos 601 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 601 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 601 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 601

In research: Kosmos 601 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 601 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 601 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1973 in spaceflight, Dnepropetrovsk Sputnik program, Kosmos satellites, so understanding it makes those chapters shorter.
In everyday life: Look for Kosmos 601 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.
