International Day of Human Space Flight

International Day of Human Space Flight 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 International Day of Human Space Flight rather than just read about it. In short: The International Day of Human Space Flight is the annual celebration, held on 12 April, of the anniversary of the first human space flight by Yuri Gagarin (USSR). It was proclaimed at the 65th session of the United Nations General Assembly on 7 April 2011, a few days before the 50th anniversary of the flight.

Key takeaways

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

Reference excerpt

The International Day of Human Space Flight is the annual celebration, held on 12 April, of the anniversary of the first human space flight by Yuri Gagarin (USSR). It was proclaimed at the 65th session of the United Nations General Assembly on 7 April 2011, a few days before the 50th anniversary of the flight. Yuri Gagarin crewed the Vostok 1 mission in 1961, completing one orbit around Earth over 108 minutes in the Vostok 3KA spacecraft, launched on a Vostok-K rocket from Baikonur Cosmodrome in Kazakhstan, USSR. In the Soviet Union, 12 April was commemorated as Cosmonautics Day since 1963, and is still observed in Russia and some former Soviet states. Yuri's Night, also known as "World Space Party", is an international observance initiated in the United States in 2001, on the 40th anniversary of Gagarin's flight. Also commemorated on this date is the first Space Shuttle launch, STS-1 of Columbia on 12 April 1981, exactly 20 years after the first human spaceflight.

Worked examples

Example 1 — a first encounter with International Day of Human Space Flight

Start with the simplest possible case. Write down what International Day of Human Space Flight 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 International Day of Human Space Flight 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 International Day of Human Space Flight 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 International Day of Human Space Flight

In research: International Day of Human Space Flight 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 International Day of Human Space Flight 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: International Day of Human Space Flight is common in secondary-school and first-year university syllabi. It links to neighbouring topics April observances, Human spaceflight, Monuments and memorials to Yuri Gagarin, so understanding it makes those chapters shorter.
In everyday life: Look for International Day of Human Space Flight 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.
