Sohae Satellite Launching Station

Sohae Satellite Launching Station is a physics 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 Sohae Satellite Launching Station rather than just read about it. In short: Sohae Satellite Launching Station (Korean: 서해위성발사장; MR: Sŏhae Wisŏng Palsajang, also known as Tongch'ang-dong Space Launch Center and Pongdong-ri) is a rocket launching site in Tongch'ang-ri, Cholsan County, North Pyongan Province, North Korea. The base is located among hills close to the northern border with China.

Key takeaways

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

Reference excerpt

Sohae Satellite Launching Station (Korean: 서해위성발사장; MR: Sŏhae Wisŏng Palsajang, also known as Tongch'ang-dong Space Launch Center and Pongdong-ri) is a rocket launching site in Tongch'ang-ri, Cholsan County, North Pyongan Province, North Korea. The base is located among hills close to the northern border with China. The spaceport was built on the site of the village Pongdong-ri which was displaced during construction. It was the site for the 13 April 2012 launch of the North Korean satellite Kwangmyŏngsŏng-3, which was launched to celebrate the 100th anniversary of the birth of Kim Il Sung. The rocket launch failed, but on 12 December of the same year Kwangmyŏngsŏng-3 Unit 2 was successfully launched and brought into Earth orbit. The launches were controversial as they were dismissed by the US as tests of ballistic missile technology and hence of breach of an agreement made between North Korea and the US in February 2012. During the 2018 North Korea–United States summit, Kim Jong Un promised that North Korea would destroy a missile engine test stand soon. The site was not initially named but was later identified to be the Sohae Satellite Launching Ground by US officials. This pledge was made official as part of the Pyongyang Declaration which Kim and South Korean leader Moon Jae-in signed at the September 2018 inter-Korean summit. On 31 October 2018, South Korean officials visited the site and confirmed it was being dismantled and ready for an upcoming inspection. But in early 2019, after a summit between North Korea and the U.S. ended without an agreement, North Korea began rebuilding of the site. A test took place in December 2019, which confirmed that the site was once again operational.

Worked examples

Example 1 — a first encounter with Sohae Satellite Launching Station

Start with the simplest possible case. Write down what Sohae Satellite Launching Station claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Sohae Satellite Launching Station 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 Sohae Satellite Launching Station 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 Sohae Satellite Launching Station

In research: Sohae Satellite Launching Station appears in physics 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 Sohae Satellite Launching Station 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: Sohae Satellite Launching Station is common in secondary-school and first-year university syllabi. It links to neighbouring topics Military installations of North Korea, Nuclear program of North Korea, Rocket launch sites in North Korea, so understanding it makes those chapters shorter.
In everyday life: Look for Sohae Satellite Launching Station 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.
