Soyuz TMA-M

Soyuz TMA-M 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 Soyuz TMA-M rather than just read about it. In short: The Soyuz TMA-M was a spacecraft developed by Energia and operated by Roscosmos for human spaceflight. Introduced in 2010, it was a revision of the Soyuz spacecraft with modernizations (the '-M' in the name) over its predecessor, the Soyuz TMA, primarily to the main flight computer and avionics.

Key takeaways

Soyuz TMA-M belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Soyuz TMA-M to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Soyuz TMA-M from memory before moving on to harder problems.

Reference excerpt

The Soyuz TMA-M was a spacecraft developed by Energia and operated by Roscosmos for human spaceflight. Introduced in 2010, it was a revision of the Soyuz spacecraft with modernizations (the '-M' in the name) over its predecessor, the Soyuz TMA, primarily to the main flight computer and avionics. It flew a total of 20 missions from 2010 to 2016, all carrying astronauts to the International Space Station (ISS). It was replaced by the Soyuz MS, which introduced further modernized systems.

Design The primary difference between the Soyuz TMA-M and the earlier Soyuz TMA was the removal of several pieces of outdated equipment, many of which were no longer in production. These included the 70-kilogram (150 lb) main digital computer, called Argon, and its analogue avionics. They were replaced with a new digital computer, the TsVM-101 and digital avionics. There were also changes to the spacecraft's structure, such as replacing the magnesium alloy used in the instrument module frame with an aluminium alloy, for easier manufacture. In combination, the changes reduced the vehicle's total mass by 70 kilograms (150 lb). Additionally, power consumption was reduced throughout the ship, improving its overall efficiency.

Flights

Two development flights were launched: Soyuz TMA-01M on Oct 7, 2010 and Soyuz TMA-02M on Jun 7, 2011. NASA astronaut Scott Kelly, who flew on TMA-01M, praised the spacecraft's new digital displays, noting that they made flying easier and less demanding. The third mission, Soyuz TMA-03M, launched on 21 December 2011 and was used for qualification tests. In addition to verifying the nominal operation of the spaceship, the testing included verification of off-nominal modes, such as manual attitude control, issuing of orbital manoeuvring pulses using four berthing and attitude thrusters, and flying around the ISS in manual control mode. Thereafter the TMA-M entered regular service, where it was used for supply and crew rotation flights to the ISS. The TMA-M variant flew another 20 missions from 2012-16, at a cadence of four times a year, all to the ISS. At that time, the Soyuz TMA-M was the only spacecraft in service that was capable of flying humans to the ISS, so ride-share agreements were in place with other space agencies. All launches carried three astronauts – there were always one or two Russians (from Roscosmos) and one American (from NASA). Half the launches included one astronaut from Europe (ESA), Canada (CSA) or Japan (JAXA).

Replacement Further development of the Soyuz capsule design led to the introduction of the Soyuz MS in 2016, which replaced the Soyuz TMA-M.

Worked examples

Example 1 — a first encounter with Soyuz TMA-M

Start with the simplest possible case. Write down what Soyuz TMA-M 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 Soyuz TMA-M 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 Soyuz TMA-M 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 Soyuz TMA-M

In research: Soyuz TMA-M 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 Soyuz TMA-M 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: Soyuz TMA-M is common in secondary-school and first-year university syllabi. It links to neighbouring topics Crewed spacecraft, Soyuz programme, Vehicles introduced in 2002, so understanding it makes those chapters shorter.
In everyday life: Look for Soyuz TMA-M 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.
