Voskhod (rocket)

Voskhod (rocket) 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 Voskhod (rocket) rather than just read about it. In short: Voskhod (Russian: Восход, lit. 'ascent/dawn', GRAU index: 11A57, Sheldon: A-2, DoD: SL-4) was Soviet medium-lift launch vehicle, a derivative of the R-7, an ICBM. The Voskhod rocket was designed for the human spaceflight programme but later used for launching Zenit reconnaissance satellites.

Key takeaways

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

Reference excerpt

Voskhod (Russian: Восход, lit. 'ascent/dawn', GRAU index: 11A57, Sheldon: A-2, DoD: SL-4) was Soviet medium-lift launch vehicle, a derivative of the R-7, an ICBM. The Voskhod rocket was designed for the human spaceflight programme but later used for launching Zenit reconnaissance satellites. It was essentially an 8K78/8K78M minus the Blok L stage and spec-wise was a halfway between the two boosters, with the former's older, lower-spec engines and the latter's improved Blok I design. Its first flight was on 16 November 1963 when it successfully launched a Zenit satellite from LC-1/5 at Baikonur. Boosters used in the Voskhod program had a man-rated version of the RD-0107 engine; this version was known as the RD-0108. Starting in 1966, the 11A57 adopted the standardized 11A511 core with the more powerful 8D74M first stage engines, however the Blok I stage continued using the RD-0107 engine rather than the RD-0110. Around 300 were flown from Baikonur and Plesetsk through 1976, almost all of them used to launch Zenit reconnaissance satellites (one exception was the Intercosmos 6 satellite in 1973). The newer 11A511U core had been introduced in 1973, but the existing stock of 11A57s took another three years to use up. The rocket had a streak of 86 consecutive successful launches between 11 September 1967 and 9 July 1970.

Worked examples

Example 1 — a first encounter with Voskhod (rocket)

Start with the simplest possible case. Write down what Voskhod (rocket) 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 Voskhod (rocket) 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 Voskhod (rocket) 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 Voskhod (rocket)

In research: Voskhod (rocket) 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 Voskhod (rocket) 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: Voskhod (rocket) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1963 in spaceflight, 1964 in spaceflight, 1965 in spaceflight, so understanding it makes those chapters shorter.
In everyday life: Look for Voskhod (rocket) 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.
