Progress 30

Progress 30 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 Progress 30 rather than just read about it. In short: Progress 30 (Russian: Прогресс 30) was a Soviet uncrewed Progress cargo spacecraft, which was launched in May 1987 to resupply the Mir space station. Launch Progress 30 launched on 19 May 1987 from the Baikonur Cosmodrome in the Kazakh SSR.

Key takeaways

Progress 30 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Progress 30 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Progress 30 from memory before moving on to harder problems.

Reference excerpt

Progress 30 (Russian: Прогресс 30) was a Soviet uncrewed Progress cargo spacecraft, which was launched in May 1987 to resupply the Mir space station.

Launch Progress 30 launched on 19 May 1987 from the Baikonur Cosmodrome in the Kazakh SSR. It used a Soyuz-U2 rocket.

Docking Progress 30 docked with the aft port of the Kvant-1 module of Mir on 21 May 1987 at 05:50:38 UTC, and was undocked on 19 July 1987 at 00:19:51 UTC.

Decay It remained in orbit until 19 July 1987, when it was deorbited. The deorbit burn occurred at 05:00:00 UTC and the mission ended at 05:42 UTC.

Worked examples

Example 1 — a first encounter with Progress 30

Start with the simplest possible case. Write down what Progress 30 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 Progress 30 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 Progress 30 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 Progress 30

In research: Progress 30 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 Progress 30 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: Progress 30 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1987 in the Soviet Union, Cargo spaceflights to Mir, Progress (spacecraft) missions, so understanding it makes those chapters shorter.
In everyday life: Look for Progress 30 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.

Frequently asked questions

What is Progress 30 in simple terms?

Progress 30 (Russian: Прогресс 30) was a Soviet uncrewed Progress cargo spacecraft, which was launched in May 1987 to resupply the Mir space station. Launch Progress 30 launched on 19 May 1987 from the Baikonur Cosmodrome in the Kazakh SSR.

Why does Progress 30 matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Progress 30?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
