Soyuz 2

Soyuz 2 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 Soyuz 2 rather than just read about it. In short: Soyuz 2 (Russian: Союз 2, Union 2) was an uncrewed spacecraft (capsule number 7K-OK-P No. 11) in the Soyuz family, intended to be the target of a docking maneuver by the crewed Soyuz 3 spacecraft. It was intended to be the first docking of a crewed spacecraft in the Soviet space program.

Key takeaways

Soyuz 2 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Soyuz 2 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Soyuz 2 from memory before moving on to harder problems.

Reference excerpt

Soyuz 2 (Russian: Союз 2, Union 2) was an uncrewed spacecraft (capsule number 7K-OK-P No. 11) in the Soyuz family, intended to be the target of a docking maneuver by the crewed Soyuz 3 spacecraft. It was intended to be the first docking of a crewed spacecraft in the Soviet space program. Although the two craft approached closely, the docking did not take place and the first successful Soviet docking of crewed spacecraft took place in the joint Soyuz 4 and Soyuz 5 mission. It served for the radio search and as a target vehicle for docking by the crewed Soyuz 3. Soyuz 2 soft-landed in a predetermined area of the Soviet Union, near the village of Maiburnak, southwest of the city of Karaganda.

Mission parameters Mass: 6,520 kg (14,370 lb) Perigee: 196.0 km (121.8 mi) Apogee: 200.0 km (124.3 mi) Inclination: 51.65° Period: 88.50 minutes

"Crew" hoax Conceptual artist Joan Fontcuberta claimed in 1997 that Soyuz 2 was crewed by Ivan Istochnikov and a dog named Kloka, who disappeared on 26 October 1968, with signs of having been hit by a meteorite. According to Fontcuberta, Soviet officials deleted Istochnikov from official Soviet history to avoid embarrassment; however, the "Sputnik Foundation" discovered Istochnikov's "voice transcriptions, videos, original annotations, some of his personal effects, and photographs taken throughout his lifetime". The exhibition of artifacts (e.g., photographs) related to "Soyuz 2" was shown in many countries, including Spain, France, Portugal, Italy, Mexico, Japan, and the United States. Among other reactions to the exhibition, a Russian ambassador "got extremely angry because [Fontcuberta] was insulting the glorious Russian past and threatened to present a diplomatic complaint". Several lines of evidence available since the first "Sputnik Foundation" exhibition in 1997 in Madrid revealed that the story and artifacts form an elaborate hoax:

The name "Ivan Istochnikov" is a Russian translation of Joan Fontcuberta's name; in specific, "Joan" and "Ivan" both translate to "John" and "Fontcuberta" and "Istochnikov" both mean "hidden fountain". The photographs of Istochnikov show Fontcuberta's face. Pages of the official website of the Madrid exhibition contain the words "PURE FICTION" toward the top of each page in light red text on a dark red background or light pink text on a white background. The front and rear endpapers of the catalog accompanying the Madrid exhibition have the words "it's all fiction" in Russian and Spanish printed on them using glow-in-the-dark ink. At the website of Spanish newspaper El Mundo, the third of three pages concerning the Madrid exhibition states that "the report which we published on the previous pages is a product of his [Fontcuberta's] imagination".

Worked examples

Example 1 — a first encounter with Soyuz 2

Start with the simplest possible case. Write down what Soyuz 2 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 Soyuz 2 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 Soyuz 2 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 Soyuz 2

In research: Soyuz 2 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 Soyuz 2 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: Soyuz 2 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1968 in the Soviet Union, Soyuz uncrewed test flights, Spacecraft launched in 1968, so understanding it makes those chapters shorter.
In everyday life: Look for Soyuz 2 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.
