Kosmos 133

Kosmos 133 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 133 rather than just read about it. In short: Kosmos 133 (Russian: Космос 133, meaning "Kosmos 133"), Soyuz 7K-OK No.2, was the first uncrewed test flight of the Soyuz spacecraft, and first mission of the Soyuz programme, as part of the Soviet space programme. Launch Launched from the Baikonur Cosmodrome aboard the maiden flight of the Soyuz 11A511 s/n U15000-02 launch vehicle.

Key takeaways

Kosmos 133 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 133 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kosmos 133 from memory before moving on to harder problems.

Reference excerpt

Kosmos 133 (Russian: Космос 133, meaning "Kosmos 133"), Soyuz 7K-OK No.2, was the first uncrewed test flight of the Soyuz spacecraft, and first mission of the Soyuz programme, as part of the Soviet space programme.

Launch Launched from the Baikonur Cosmodrome aboard the maiden flight of the Soyuz 11A511 s/n U15000-02 launch vehicle. Kosmos 133 was planned "all up" test, to include an automated docking with a second Soyuz spacecraft (Soyuz 7K-OK No.1), which was scheduled for launch the day after Kosmos 133.

Mission Kosmos 133 was operated in a low Earth orbit, on 28 November 1966, it had a perigee of 171.0 km (106.3 mi), an apogee of 223.0 km (138.6 mi), an inclination of 51.9°, and an orbital period of 88.4 minutes.

Return Problems found during ground testing of the second spacecraft resulted in its launch being delayed, and it was destroyed when its launch vehicle exploded on its launch pad following a scrubbed launch attempt in December 1966. Before this, the attitude control system (ACS) of Kosmos 133 malfunctioned, resulting in rapid consumption of orientation fuel, leaving it spinning at 2 rpm. After large efforts by ground control and 5 attempts at retrofire over two days, the craft was finally coming down for a landing. Due to the inaccuracy of the reentry burn, it was determined that the capsule would land in China. The self-destruct command was given and the satellite exploded on the 30th of November 1966 at 10:21 GMT. The fireball passed over west Japan and was recorded by photos and a sketch. Kōichirō Tomita identified that it was the Kosmos 133 spacecraft (30 November 1966).

Worked examples

Example 1 — a first encounter with Kosmos 133

Start with the simplest possible case. Write down what Kosmos 133 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 133 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 133 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 133

In research: Kosmos 133 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 133 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 133 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1966 in the Soviet Union, Kosmos satellites, Soyuz uncrewed test flights, so understanding it makes those chapters shorter.
In everyday life: Look for Kosmos 133 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.
