Istrebitel Sputnikov

Istrebitel Sputnikov 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 Istrebitel Sputnikov rather than just read about it. In short: Istrebitel Sputnikov, or IS (Russian: Истребитель спутников, ИС, meaning "destroyer of satellites"), was a Soviet anti-satellite weapons programme which led to the deployment of the IS-A or I2P system during the 1970s and 1980s. IS satellites were originally intended to launch on UR-200 rockets, but following the cancellation of the UR-200, the Polyot, Tsyklon-2A and Tsyklon-2 rockets were used instead.

Key takeaways

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

Reference excerpt

Istrebitel Sputnikov, or IS (Russian: Истребитель спутников, ИС, meaning "destroyer of satellites"), was a Soviet anti-satellite weapons programme which led to the deployment of the IS-A or I2P system during the 1970s and 1980s. IS satellites were originally intended to launch on UR-200 rockets, but following the cancellation of the UR-200, the Polyot, Tsyklon-2A and Tsyklon-2 rockets were used instead.

History The first test flights of the IS spacecraft used the I1P configuration, and served to demonstrate the propulsion and control systems of the spacecraft. Both were launched by Polyot rockets, and were designated Polyot 1 and Polyot 2. They were launched on 1 November 1963 and 12 April 1964 respectively. Following this, IS-A or I2P interceptors and IS-P or I2M targets were launched. Only four IS-P targets were launched before the type was replaced by the cheaper DS-P1-M satellite, launched as part of the Dnepropetrovsk Sputnik programme. Later IS-A tests intercepted DS-P1-M satellites, or the Lira satellites that succeeded them.

Kosmos 248 intercept In November 1968, 4 years after Polyot 1 and 2 were tested for a potential Satellite intercept, Kosmos 248 was successfully destroyed by Kosmos 252 which came within the 5km 'kill radius' and destroyed Kosmos 248 by detonating its warhead.

Worked examples

Example 1 — a first encounter with Istrebitel Sputnikov

Start with the simplest possible case. Write down what Istrebitel Sputnikov 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 Istrebitel Sputnikov 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 Istrebitel Sputnikov 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 Istrebitel Sputnikov

In research: Istrebitel Sputnikov 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 Istrebitel Sputnikov 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: Istrebitel Sputnikov is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1963 in spaceflight, 1982 in spaceflight, Abandoned military projects of the Soviet Union, so understanding it makes those chapters shorter.
In everyday life: Look for Istrebitel Sputnikov 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.
