Soyuz MS-24

Soyuz MS-24 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 MS-24 rather than just read about it. In short: Soyuz MS-24, Russian production No. 755 and identified by NASA as Soyuz 70S, was a Russian crewed Soyuz spaceflight launched from Baikonur on 15 September 2023 to the International Space Station. Crew The crew was originally assigned to Soyuz MS-23, but they were moved to MS-24 due to a coolant leak on Soyuz MS-22 that required MS-23 to be launched uncrewed as its replacement and returned to Earth uncrewed.

Key takeaways

Soyuz MS-24 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 MS-24 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Soyuz MS-24 from memory before moving on to harder problems.

Reference excerpt

Soyuz MS-24, Russian production No. 755 and identified by NASA as Soyuz 70S, was a Russian crewed Soyuz spaceflight launched from Baikonur on 15 September 2023 to the International Space Station.

Crew The crew was originally assigned to Soyuz MS-23, but they were moved to MS-24 due to a coolant leak on Soyuz MS-22 that required MS-23 to be launched uncrewed as its replacement and returned to Earth uncrewed. Oleg Kononenko was assigned for a one year long mission with his MS-24 crewmate Nikolai Chub that started on September 15, 2023. As the mission lasted 374 days, Kononenko spent a total of 1,111 days in space. He exceeded the previous record of 878 days held by Gennady Padalka on 4 February 2024. He later became the first person to stay 900, 1,000, and 1,100 days in space on 25 February 2024, 4 June 2024, and 12 September 2024 respectively.

Undocking and Return At the end of Expedition 70, O'Hara returned to Earth on Soyuz MS-24 with Roscosmos cosmonaut Oleg Novitsky and Belarusian spaceflight participant Marina Vasilevskaya (both on ISS EP-21) on 6 April 2024. On the other hand, Kononenko and Chub remained onboard the orbital laboratory for a year and returned to Earth with NASA astronaut Tracy Caldwell-Dyson on Soyuz MS-25. As the mission lasted 374 days, Kononenko spent a total of 1,111 days in space by the time he returned to Earth. He broke the world record of 878 days in space held by Gennady Padalka on February 4, 2024 at 07:30:08 UTC. He later became the first person to stay 900, 1,000, and 1,100 days in space on 25 February 2024, 4 June 2024, and 12 September 2024 respectively.

Worked examples

Example 1 — a first encounter with Soyuz MS-24

Start with the simplest possible case. Write down what Soyuz MS-24 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 MS-24 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 MS-24 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 MS-24

In research: Soyuz MS-24 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 MS-24 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 MS-24 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2023 in Russia, Crewed Soyuz missions, Human spaceflights to the International Space Station, so understanding it makes those chapters shorter.
In everyday life: Look for Soyuz MS-24 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.
