Progress M-20M

Progress M-20M 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-20M rather than just read about it. In short: Progress M-20M (Russian: Прогресс М-20М), identified by NASA as Progress 52P, is a Progress spacecraft used by Roskosmos to resupply the International Space Station (ISS) during 2013. Progress M-20M was built by RKK Energia.

Key takeaways

Progress M-20M 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-20M to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Progress M-20M from memory before moving on to harder problems.

Reference excerpt

Progress M-20M (Russian: Прогресс М-20М), identified by NASA as Progress 52P, is a Progress spacecraft used by Roskosmos to resupply the International Space Station (ISS) during 2013. Progress M-20M was built by RKK Energia. Progress M-20M was launched on a 6-hours rendezvous profile towards the ISS. The 20th Progress-M 11F615A60 spacecraft to be launched, it had the serial number 420 and was built by RKK Energia.

Launch The spacecraft was launched on 27 July 2013 at 20:45 UTC from the Baikonur Cosmodrome in Kazakhstan. The launch was the first out of Baikonur since a disastrous Proton-M failure on 2 July 2013.

Docking Progress M-20M docked with the Pirs docking compartment on 28 July 2013 at 02:26 UTC, less than six hours after launch.

Cargo Some last minute items were added to the Progress to assist the station astronauts with figuring out why the cooling system on one of the American spacesuits sprung a leak and caused a spacewalk to be aborted the previous week.

Undocking and reentry Progress M-20M undocked from the ISS on 3 February 2014.

Worked examples

Example 1 — a first encounter with Progress M-20M

Start with the simplest possible case. Write down what Progress M-20M 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-20M 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-20M 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-20M

In research: Progress M-20M 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-20M 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-20M is common in secondary-school and first-year university syllabi. It links to neighbouring topics Progress (spacecraft) missions, Russian spacecraft stubs, Spacecraft launched by Soyuz-U rockets, so understanding it makes those chapters shorter.
In everyday life: Look for Progress M-20M 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.
