Progress M-2

Progress M-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 Progress M-2 rather than just read about it. In short: Progress M-2 (Russian: Прогресс М-2), was a Soviet uncrewed cargo spacecraft which was launched in 1989 to resupply the Mir space station. The nineteenth of sixty four Progress spacecraft to visit Mir, it used the Progress-M 11F615A55 configuration, and had the serial number 202.

Key takeaways

  • Progress M-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 Progress M-2 to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Progress M-2 from memory before moving on to harder problems.

Reference excerpt

Progress M-2 (Russian: Прогресс М-2), was a Soviet uncrewed cargo spacecraft which was launched in 1989 to resupply the Mir space station. The nineteenth of sixty four Progress spacecraft to visit Mir, it used the Progress-M 11F615A55 configuration, and had the serial number 202. It carried supplies including food, water and oxygen for the EO-5 crew aboard Mir, as well as equipment for conducting scientific research, and fuel for adjusting the station's orbit and performing manoeuvres. Progress M-2 was launched at 03:30:50 GMT on 20 December 1989, atop a Soyuz-U2 carrier rocket flying from Site 1/5 at the Baikonur Cosmodrome. It docked with the aft port of the Kvant-1 module of Mir at 05:41:21 GMT on 22 December. During the time it was docked, Mir was in an orbit of around 390 by 393 kilometres (211 by 212 nmi). Progress M-2 remained docked with Mir for forty eight days before undocking at 02:33:07 GMT on 9 February 1990 to make way for the Soyuz TM-9 spacecraft, carrying the EO-6 crew to the station. Progress M-2 was deorbited at 07:07:00 GMT, a few hours after it had undocked. It burned up in the atmosphere over the Pacific Ocean, with any remaining debris landing in the ocean at around 07:56 GMT.

Worked examples

Example 1 — a first encounter with Progress M-2

Start with the simplest possible case. Write down what Progress M-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 Progress M-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 Progress M-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 Progress M-2

In research
Progress M-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 Progress M-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
Progress M-2 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1989 in the Soviet Union, 1990 in spaceflight, Cargo spaceflights to Mir, so understanding it makes those chapters shorter.
In everyday life
Look for Progress M-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.

Frequently asked questions

What is Progress M-2 in simple terms?

Progress M-2 (Russian: Прогресс М-2), was a Soviet uncrewed cargo spacecraft which was launched in 1989 to resupply the Mir space station. The nineteenth of sixty four Progress spacecraft to visit Mir, it used the Progress-M 11F615A55 configuration, and had the serial number 202.

Why does Progress M-2 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 M-2?

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.
