List of human spaceflights

List of human spaceflights 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 List of human spaceflights rather than just read about it. In short: This is a list of all crewed spaceflights throughout history. Beginning in 1961 with the flight of Yuri Gagarin aboard Vostok 1, crewed spaceflight occurs when a human crew flies a spacecraft into outer space.

Key takeaways

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

Reference excerpt

This is a list of all crewed spaceflights throughout history. Beginning in 1961 with the flight of Yuri Gagarin aboard Vostok 1, crewed spaceflight occurs when a human crew flies a spacecraft into outer space. Human spaceflight is distinguished from spaceflight generally, which entails both crewed and uncrewed spacecraft. There are two definitions of spaceflight. The Fédération Aéronautique Internationale (FAI), an international record-keeping body, defines the boundary between Earth's atmosphere and outer space at 100 kilometres (62 mi) above sea level. This boundary is known as the Kármán line. The United States awards astronaut wings to qualified personnel who pilot a spaceflight above an altitude of 50 miles (80 km). As of the launch of Soyuz MS-29 on 14 July 2026, there have been 415 human spaceflights.

Three of these were launched without crew but returned crew to Earth after damage to the crew's original vehicle. These were Soyuz 34, Soyuz MS-23 and Shenzhou 22. Two missions did not cross either the Kármán line or the U.S. definition of space and therefore do not qualify as spaceflights. These were the fatal STS-51-L (Challenger disaster), and the non-fatal aborted Soyuz mission T-10a. Two non-fatal aborted missions crossed either the Kármán line or the U.S. definition of space. One was the Soyuz mission MS-10, which did not reach the Kármán line but did pass the 80 km (50 mi) line. The other was the Soyuz mission 18a, which crossed the Kármán line. Four missions successfully achieved human spaceflight, yet ended as fatal failures as their crews died during the return. These were Soyuz 1, X-15 flight 191, Soyuz 11, and STS-107 (Columbia disaster). Twenty four flights in total reached an apogee beyond 80 kilometres (50 mi), but failed to go beyond 100 kilometres (62 mi), so therefore do not qualify as spaceflights under the FAI definition.

Summary Since 1961, three countries (China, Russia, and the United States) and one former country (Soviet Union) have conducted human spaceflight using seventeen different spacecraft series, or: "programs", "projects".

Human spaceflights The Salyut series, Skylab, Mir, ISS, and Tiangong series space stations, with which many of these flights docked in orbit, are not listed separately here. See the detailed lists (links below) for information.

Missions which were intended to reach space but which failed to do so are listed in bold. Missions with a maximum altitude between 50 miles (80.45 km) and 100 kilometers (62 mi), which satisfy the US Military definition of space (50 mi), but not the internationally recognized FAI and NASA definition of the Kármán Line (100 km), are listed in italics. Fatal missions are marked with a dagger (†) symbol.

Notes

External links Spacefacts Compare with the present article. The Spacefacts list includes most flights listed here, but omits twelve: The three failed launches of STS-51-L, Soyuz T-10a and Soyuz MS-10, none of which achieved human spaceflight, the uncrewed launch of Soyuz 34 (which nevertheless returned a crew to Earth), and the eight sub-orbital human spaceflights: Mercury-Redstone 3 and 4, X-15 flights 90 and 91, SpaceShipOne flights 15P, 16P and 17P, and Soyuz 18a. Astronautix Similarly, see the list for "Manned Spaceflight" given at Astronautix, which includes other related categories.

Worked examples

Example 1 — a first encounter with List of human spaceflights

Start with the simplest possible case. Write down what List of human spaceflights 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 List of human spaceflights 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 List of human spaceflights 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 List of human spaceflights

In research
List of human spaceflights 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 List of human spaceflights 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
List of human spaceflights is common in secondary-school and first-year university syllabi. It links to neighbouring topics Human spaceflight, Lists of human spaceflights, Spaceflight timelines, so understanding it makes those chapters shorter.
In everyday life
Look for List of human spaceflights 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.
