Progress M-17

Progress M-17 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-17 rather than just read about it. In short: Progress M-17 (Russian: Прогресс М-17) was a Russian uncrewed cargo spacecraft which was launched in 1993 to resupply the Mir space station. The thirty-fifth of sixty-four Progress spacecraft to visit Mir, it used the Progress-M 11F615A55 configuration, and had the serial number 217.

Key takeaways

Progress M-17 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-17 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Progress M-17 from memory before moving on to harder problems.

Reference excerpt

Progress M-17 (Russian: Прогресс М-17) was a Russian uncrewed cargo spacecraft which was launched in 1993 to resupply the Mir space station. The thirty-fifth of sixty-four Progress spacecraft to visit Mir, it used the Progress-M 11F615A55 configuration, and had the serial number 217. In addition to delivering cargo, Progress M-17 was also used to demonstrate extended duration Progress missions; remaining in orbit for almost a year with a docked phase lasting 132 days.

Launch and docking Progress M-17 was launched at 03:34:13 GMT on 31 March 1993, 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 at 05:16:18 GMT on 1 April, less than 26 hours after launch. The rocket had the serial number N15000-069. The spacecraft carried supplies including food, water and oxygen for the EO-13 and EO-14 crews aboard Mir, as well as equipment for conducting scientific research, and fuel for adjusting the station's orbit and performing manoeuvres. In all, Progress M-17 delivered 2,604 kilograms (5,741 lb) of cargo to Mir. It carried the seventh VBK-Raduga recoverable capsule, however due to the extended duration mission this was returned by Progress M-18.

Extended mission Progress M-17 was originally scheduled to conduct a normal length mission, however it remained docked with Mir for 132 days because of a longer than usual gap between missions requiring its docking port. Soyuz TM-16 had docked with the Kristall module in order to test the APAS-89 docking system ahead of its use in the Shuttle-Mir programme, leaving the forward port free for Progress M-18, whose docking marked the first time two Progress spacecraft had been docked to a station simultaneously. It undocked from Mir at 15:36:42 GMT on 11 August. Due to its extended mission, the spacecraft did not have sufficient fuel remaining to deorbit, and it was therefore kept in orbit for 205 days of free flight, until its orbit had decayed sufficiently for a deorbit burn to be conducted with what fuel remained. During this time, Progress M-17 was used for further tests of the spacecraft's longevity. After being manoeuvred into an orbit away from the station, its systems were deactivated and it was kept in a low-power configuration. On 2 March the spacecraft was reactivated and successfully completed a series of manoeuvres to prove that it could still operate after having been in orbit for so long. The next day, Progress M-17 was deorbited and reentered the atmosphere over the South America, breaking up at around 03:28 GMT.

Worked examples

Example 1 — a first encounter with Progress M-17

Start with the simplest possible case. Write down what Progress M-17 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-17 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-17 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-17

In research: Progress M-17 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-17 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-17 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1994 in spaceflight, Cargo spaceflights to Mir, Progress (spacecraft) missions, so understanding it makes those chapters shorter.
In everyday life: Look for Progress M-17 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.
