Progress MS-14

Progress MS-14 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 MS-14 rather than just read about it. In short: Progress MS-14 (Russian: Прогресс МC-14), Russian production No.448, identified by NASA as Progress 75P, was a Progress spaceflight operated by Roscosmos to resupply the International Space Station (ISS). This was the 166th flight of a Progress spacecraft.

Key takeaways

Progress MS-14 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 MS-14 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Progress MS-14 from memory before moving on to harder problems.

Reference excerpt

Progress MS-14 (Russian: Прогресс МC-14), Russian production No.448, identified by NASA as Progress 75P, was a Progress spaceflight operated by Roscosmos to resupply the International Space Station (ISS). This was the 166th flight of a Progress spacecraft.

History The Progress-MS was an uncrewed freighter based on the Progress-M featuring improved avionics. This improved variant first launched on 21 December 2015. It has the following improvements:

New external compartment that enables it to deploy satellites. Each compartment can hold up to four launch containers. First time installed on Progress MS-03. Enhanced redundancy thanks to the addition of a backup system of electrical motors for the docking and sealing mechanism. Improved Micrometeoroid (MMOD) protection with additional panels in the cargo compartment. Luch Russian relay satellites link capabilities enable telemetry and control even when not in direct view of ground radio stations. GNSS autonomous navigation enables real time determination of the status vector and orbital parameters dispensing with the need of ground station orbit determination. Real time relative navigation thanks to direct radio data exchange capabilities with the space station. New digital radio that enables enhanced TV camera view for the docking operations. The Ukrainian Chezara Kvant-V on board radio system and antenna/feeder system has been replaced with a Unified Command Telemetry System (UCTS). Replacement of the Kurs A with Kurs NA digital system.

Spacecraft This flight was dedicated to the 75th anniversary of Victory: the Ribbon of Saint George and the orders of the Second World War were put on board the Soyuz. In order to prevent the Progress MS-14 coronavirus from entering the station, it underwent additional disinfection before launch before being sent. First of all, disinfection of the internal surfaces and equipment, as well as the external surfaces of the goods delivered was carried out with the selection of control samples. After refueling the vessel and upgrading the equipment, additional disinfection was carried out to prevent the virus from entering the ISS.

Launch The Soyuz-2.1a used to launch Progress MS-14, dubbed the "Victory Rocket" was decorated with the number "75" on its payload fairing to mark the 75th anniversary of the meeting of U.S. and Soviet troops on the Elbe River in Germany in the final days of World War II in Europe. The number has a double significance because the cargo mission is the 75th Progress resupply flight to the International Space Station since 2000. Progress MS-14 was launched at 01:51:41 UTC from Baikonur Site 31/6 on a fast-track trajectory. Following a nominal launch, Progress MS-14 docked with Zvezda on the ISS at 05:11:56 UTC.

Docking 3 hours and 20 minutes after launch, Progress MS-14 successfully docked automatically to the rear port of Zvezda at 05:11:56 UTC on 25 April 2020, where it remained until 27 April 2021.

Cargo The Progress MS-14 spacecraft delivered 2528 kg of cargo, with 1358 kg of this being dry cargo. The following is a breakdown of cargo bound for the ISS:

Dry cargo: 1358 kg Fuel: 700 kg Oxygen: 50 kg Water: 420 kg

Undocking and decay After its mission was completed, Progress MS-14 undocked from the station on 27 April 2021 filled with disposable trash. It re-entered the Earth's atmosphere for destruction over the South Pacific Ocean at 00:42 UTC, on 29 April 2021.

Worked examples

Example 1 — a first encounter with Progress MS-14

Start with the simplest possible case. Write down what Progress MS-14 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 MS-14 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 MS-14 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 MS-14

In research: Progress MS-14 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 MS-14 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 MS-14 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2020 in Russia, Progress (spacecraft) missions, Spacecraft launched by Soyuz-2 rockets, so understanding it makes those chapters shorter.
In everyday life: Look for Progress MS-14 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.
