Kwangmyŏngsŏng-3 (reflight)
Kwangmyŏngsŏng-3 () was a North Korean Earth observation satellite which, according to the DPRK, was for weather forecast purposes, and whose launch was widely portrayed in the West to be a veiled ballistic missile test. The satellite was launched on 13 April 2012 at 07:39 Korean Standard Time, KST aboard the Unha, Unha-3 carrier rocket from Sohae Satellite Launching Station. The rocket exploded 90 seconds after launch near the end of the firing of the Multistage rocket, first stage of the rocket. The launch was planned to mark the centenary of the birth of Kim Il Sung, the founder of the republic. On 1 December 2012 North Korea announced that Kwangmyŏngsŏng-3 (reflight), a replacement satellite would be launched between 10 and 22 December 2012. After a delay and extending the launch window to 29 December, Kwangmyŏngsŏng-3 Unit 2, the rocket was launched on 12 December 2012 (39026, 280km x 280km, 97 (2023).).

Earth Observation
Earth observation (EO) is the gathering of information about the physical, chemical, and biosphere, biological systems of the planet Earth. It can be performed via remote sensing, remote-sensing technologies (Earth observation satellites) or through direct-contact sensors in ground-based or airborne platforms (such as weather stations and weather balloons, for example). According to the Group on Earth Observations (GEO), the concept encompasses both "space-based or remotely-sensed data, as well as ground-based or In situ#Earth and atmospheric sciences, in situ data". Earth observation is used to monitor and assess the status of and changes in natural environment, natural and built environments. Terminology In Europe, ''Earth observation'' has often been used to refer to satellite-based remote sensing, but the term is also used to refer to any form of observations of the Earth system, including in situ and airborne observations, for example. The GEO, which has over 100 member coun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multistage Rocket
A multistage rocket or step rocket is a launch vehicle that uses two or more rocket ''stages'', each of which contains its own engines and propellant. A ''tandem'' or ''serial'' stage is mounted on top of another stage; a ''parallel'' stage is attached alongside another stage. The result is effectively two or more rockets stacked on top of or attached next to each other. Two-stage rockets are quite common, but rockets with as many as five separate stages have been successfully launched. By jettisoning stages when they run out of propellant, the mass of the remaining rocket is decreased. Each successive stage can also be optimized for its specific operating conditions, such as decreased atmospheric pressure at higher altitudes. This ''staging'' allows the thrust of the remaining stages to more easily accelerate the rocket to its final velocity and height. In serial or tandem staging schemes, the first stage is at the bottom and is usually the largest, the second stage and subse ...

Celestial Navigation
Celestial navigation, also known as astronavigation, is the practice of position fixing using stars and other celestial bodies that enables a navigator to accurately determine their actual current physical position in space or on the surface of the Earth without relying solely on estimated positional calculations, commonly known as dead reckoning. Celestial navigation is performed without using satellite navigation or other similar modern electronic or digital positioning means. Celestial navigation uses "sights," or timed angular measurements, taken typically between a celestial body (e.g., the Sun, the Moon, a planet, or a star) and the visible horizon. Celestial navigation can also take advantage of measurements between celestial bodies without reference to the Earth's horizon, such as when the Moon and other selected bodies are used in the practice called "lunars" or the Lunar distance (navigation), lunar distance method, used for determining precise time when time is u ...

Mount Paektu
Paektu Mountain or Baekdu Mountain () is an active stratovolcano on the Chinese–North Korean border. In China, it is known as Changbai Mountain (). At , it is the tallest mountain in North Korea and Northeast China and the tallest mountain of the Baekdu-daegan and Changbai mountain ranges. The highest peak, called Janggun Peak, belongs to North Korea. The mountain notably has a caldera that contains a large crater lake called Heaven Lake, and is also the source of the Songhua, Tumen, and Yalu rivers. Korean and Manchu people assign a mythical quality to the mountain and its lake, and consider the mountain to be their ancestral homeland. The mountain's caldera was formed by an eruption in 946 that released about of tephra. The eruption was among the largest and most powerful eruptions on Earth in the last 5,000 years. The volcano last erupted in 1903, and is expected to erupt around every hundred years. In the 2010s, concerns over an upcoming eruption prompted sev ...

Russian Far East
The Russian Far East ( rus, Дальний Восток России, p=ˈdalʲnʲɪj vɐˈstok rɐˈsʲiɪ) is a region in North Asia. It is the easternmost part of Russia and the Asia, Asian continent, and is coextensive with the Far Eastern Federal District, which encompasses the area between Lake Baikal and the Pacific Ocean. The area's largest city is Khabarovsk, followed by Vladivostok. The region shares land borders with the countries of Mongolia, China, and North Korea to its south, as well as maritime boundary, maritime boundaries with Japan to its southeast, and with the United States along the Bering Strait to its northeast. Although the Russian Far East is often considered as a part of Siberia abroad, it has been historically categorized separately from Siberia in Russian regional schemes (and previously during the history of the Soviet Union, Soviet era when it was called the Soviet Far East).

Kim Family Cult
The North Korean cult of personality surrounding the Kim family has existed in North Korea for decades and can be found in many examples of North Korean culture. Although not acknowledged by the North Korean government, many defectors and Western visitors state there are often stiff penalties for those who criticize or do not show "proper" respect for the former leaders of the country, Kim Il Sung and Kim Jong Il, officially referred to as " eternal leaders of Korea". The personality cult began soon after Kim Il Sung took power in 1948, and was greatly expanded after his death in 1994. While other countries have had cults of personality to various degrees, the pervasiveness and extreme nature of North Korea's personality cult surpasses that of both its original influences, Joseph Stalin and Mao Zedong. The cult is also marked by the intensity of the people's feelings for and devotion to their leaders, and the key role played by a Confucianized ideology of familism both in main ...

North Korean Nationalism
Korean nationalism can be viewed in two different contexts. One encompasses various movements throughout history to maintain a Korean cultural identity, history, and ethnicity (or "race"). This ethnic nationalism was mainly forged in opposition to foreign incursion and rule. The second context encompasses how Korean nationalism changed after the partition in 1945. Today, the former tends to predominate. History Historically, Korean nationalism, or its earliest concept can be found as early as Silla, who expressed its unification as a unification of Samhan. Other examples of this would be Goryeo, whose name signifies that it is a direct descendant of Goguryeo, as they took its exact name as its own. The same goes for Joseon, who took its name from Gojoseon. However, the current concept of Korean nationalism came to be emphasized in order to resist Japanese influence during Japanese Occupation. The central objectives of Korea's nationalist movement were the advancement and pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kwangmyŏngsŏng-3 Unit 2
Kwangmyŏngsŏng-3 Unit 2 () was the first satellite successfully launched from North Korea, an Earth observation spacecraft that was launched on 12 December 2012, 00:49 UTC, in order to replace the original Kwangmyŏngsŏng-3, which failed to reach orbit on 13 April 2012. The United Nations Security Council condemned the satellite launch, regarding it as a violation of the ban on North Korean ballistic missile tests, as the rocket technology is the same. The launch came during the period when the DPRK was commemorating the first anniversary of the death of former leader Kim Jong Il and just before the first South Korean domestic launch of a satellite and the South Korean presidential election on 19 December 2012. The successful launch makes the DPRK the tenth space power capable of putting satellites in orbit using its own launch vehicles. North Korea declared the launch successful, and the South Korean military and North American Aerospace Defense Command (NORAD) reporte ...
