Korabl-Sputnik 4

Korabl-Sputnik 4 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 Korabl-Sputnik 4 rather than just read about it. In short: Korabl-Sputnik 4 (Russian: Корабль-Спутник 4 meaning Ship-Satellite 4) or Vostok-3KA No.1, also known as Sputnik 9 in the West, was a Soviet spacecraft which was launched on 9 March 1961. Carrying the mannequin Ivan Ivanovich, a dog named Chernushka, some mice and the first guinea pig in space, it was a test flight of the Vostok spacecraft.

Key takeaways

Korabl-Sputnik 4 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Korabl-Sputnik 4 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Korabl-Sputnik 4 from memory before moving on to harder problems.

Reference excerpt

Korabl-Sputnik 4 (Russian: Корабль-Спутник 4 meaning Ship-Satellite 4) or Vostok-3KA No.1, also known as Sputnik 9 in the West, was a Soviet spacecraft which was launched on 9 March 1961. Carrying the mannequin Ivan Ivanovich, a dog named Chernushka, some mice and the first guinea pig in space, it was a test flight of the Vostok spacecraft.

Korabl-Sputnik 4 was launched at 06:29:00 UTC on 9 March 1961, atop a Vostok-K carrier rocket flying from Site 1/5 at the Baikonur Cosmodrome. It was successfully placed into low Earth orbit. The spacecraft was only intended to complete a single orbit, so it was deorbited shortly after launch, and reentered on its first pass over the Soviet Union. It landed at 08:09:54 UTC, and was successfully recovered. During the descent, the mannequin was ejected from the spacecraft in a test of its ejection seat, and descended separately under its own parachute.

Worked examples

Example 1 — a first encounter with Korabl-Sputnik 4

Start with the simplest possible case. Write down what Korabl-Sputnik 4 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 Korabl-Sputnik 4 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 Korabl-Sputnik 4 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 Korabl-Sputnik 4

In research: Korabl-Sputnik 4 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 Korabl-Sputnik 4 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: Korabl-Sputnik 4 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1961 in the Soviet Union, March 1961, Spacecraft launched in 1961, so understanding it makes those chapters shorter.
In everyday life: Look for Korabl-Sputnik 4 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.
