Progress M-01M

Progress M-01M 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-01M rather than just read about it. In short: Progress M-01M (Russian: Прогресс М-01М), identified by NASA as Progress 31P, was a Progress spacecraft used to resupply the International Space Station. It was the first flight of the Progress-M 11F615A60, which featured a TsVM-101 digital flight computer and MBITS digital telemetry system, in place of the earlier analogue systems.

Key takeaways

Progress M-01M 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-01M to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Progress M-01M from memory before moving on to harder problems.

Reference excerpt

Progress M-01M (Russian: Прогресс М-01М), identified by NASA as Progress 31P, was a Progress spacecraft used to resupply the International Space Station. It was the first flight of the Progress-M 11F615A60, which featured a TsVM-101 digital flight computer and MBITS digital telemetry system, in place of the earlier analogue systems. It was the first Progress-M 11F615A60 spacecraft, and had the serial number 401.

Launch It was launched at 12:38 UTC on 26 November 2008 from Site 1/5 at the Baikonur Cosmodrome in Kazakhstan, atop a Soyuz-U carrier rocket. Following a four-day free flight, it docked with Pirs module of the ISS at 12:28 UTC on 30 November 2008.

Antenna problem Immediately after launch, an antenna used by the spacecraft's Kurs docking system failed to deploy. The antenna was successfully deployed about three hours later after flight controllers resent the deployment command, however the spacecraft was docked using the backup TORU system, controlled by cosmonaut Yury Lonchakov, as a precaution.

Docking It remained docked until 6 February 2009, when it undocked at 04:10 UTC. It subsequently spent two days in free flight, before being deorbited, and burning up in the atmosphere at 08:19 UTC on 8 February 2009.

Cargo Progress M-01M carried 2,423 kilograms (5,342 lb) of cargo, consisting of which 820 kilograms (1,810 lb) of fuel, 210 kilograms (460 lb) of water, and 1,343 kilograms (2,961 lb) of dry cargo. The dry cargo included Japanese food for Koichi Wakata, who arrived aboard the station in March 2009 as part of Expedition 18.

Worked examples

Example 1 — a first encounter with Progress M-01M

Start with the simplest possible case. Write down what Progress M-01M 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-01M 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-01M 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-01M

In research: Progress M-01M 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-01M 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-01M is common in secondary-school and first-year university syllabi. It links to neighbouring topics Progress (spacecraft) missions, Spacecraft launched by Soyuz-U rockets, Spacecraft launched in 2008, so understanding it makes those chapters shorter.
In everyday life: Look for Progress M-01M 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.
