Kwangmyŏngsŏng-1
Kwangmyŏngsŏng-1 or Gwangmyeongseong-1 ( ko, 광명성 1호, Hanja: , meaning Bright Star 1) was a satellite allegedly launched by North Korea on 31 August 1998. While the North Korean government claimed that the launch was successful, no objects were ever tracked in orbit from the launch, and outside North Korea it is considered to have been a failure. It was the first satellite to be launched as part of the Kwangmyŏngsŏng program, and the first satellite that North Korea attempted to launch. It was launched from Musudan-ri using a Paektusan rocket, at 03:07 GMT on 31 August 1998, a few days before the 50th anniversary of North Korea's independence from Japan. On 4 September, the Korean Central News Agency announced that the satellite had successfully been placed into low Earth orbit. The China National Space Administration was involved in the development of Kwangmyŏngsŏng-1, which had a 72-faced polyhedral shape, similar to Dong Fang Hong I, the first Chinese satellit ...

Kwangmyŏngsŏng Program
The Kwangmyŏngsŏng program is a class of experimental satellites developed by North Korea. The name Kwangmyŏngsŏng ("bright star", "brilliant star" or "constellation" in Korean) is from a poem written by Kim Il-sung. The first class of satellites built by North Korea, the program started in the mid-1980s. There have been five launches so far, of which two have been successful. Background According to North Korea Academy of Science's Academician Kwon Tong-hwa, the SLV was developed in the 1980s when late leader Kim Il-sung announced the decision to launch a North Korean satellite. The decision to send a North Korean satellite was precipitated by the successful launching of South Korea's first satellite, Uribyol-1, on 10 August 1992 and its second satellite, Uribyol 2, on 26 September 1993, both by a European Ariane 4 SLV. In a late-1993 meeting of the Korean Workers' Party Central Committee, Kim Il-sung expressed his desire to quickly place a satellite into orbit, leadin ...

Korean Committee Of Space Technology
The Korean Committee of Space Technology (KCST; , Hanja: 朝鮮宇宙空間技術委員會) was the agency of the government of the Democratic People's Republic of Korea (North Korea) responsible for the country's space program. The agency was terminated and succeeded by the National Aerospace Development Administration in 2013 after the Law on Space Development was passed in the 7th session of the 12th Supreme People's Assembly. History Very little information on it is publicly available. It is known to have been founded sometime in the 1980s, and most likely is connected to the Artillery Guidance Bureau of the Korean People's Army. Operations The KCST was responsible for all operations concerning space exploration and construction of satellites. On 12 March 2009, North Korea signed the Outer Space Treaty and the Registration Convention, after a previous declaration of preparations for a new satellite launch. Facilities The KCST operated the Tonghae Satellite Launching Ground ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Musudan-ri
The Tonghae Satellite Launching Ground, also known as Musudan-ri (), is a rocket launching site in North Korea. Location It lies in southern Hwadae County, North Hamgyong Province, near Musu Dan, the cape marking the northern end of the East Korea Bay. The area was formerly known as Taep'o-dong (대포동) during the period when Korea was occupied by Japan, and the Taepodong rockets take their name from this. This single loose-surface road is susceptible to seasonal flooding. The site is 45 km northeast of port city of Kimchaek and 45 kilometers (28 miles) from the town of Kilju (길주읍). There is a small wharf located at the fishing village of Tongha-dong but can only accommodate vessels smaller than 40 meters in length. History By the early 80s, North Korea needed a flight-test facility for its program to reverse-engineer and produce copies of the Scud-B which it acquired from the Soviet Union in the late 60s. Previously, North Korea used a facility at Hwajin-ri ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paektusan (rocket)
Taepodong-1 ( ko, 대포동-1) was a three-stage technology demonstrator developed by North Korea, a development step toward an intermediate-range ballistic missile. The missile was derived originally from the Scud rocket and was tested once in 1998 as a space launch vehicle. As a space launch vehicle, it was sometimes called the Paektusan 1. History On August 31, 1998, North Korea announced that they had used this rocket to launch their first satellite Kwangmyŏngsŏng-1 from a pad on the Musudan-ri peninsula. However, the satellite failed to achieve orbit; outside observers conjecture that the additional third stage either failed to fire or malfunctioned. This is contrary to official statements of the North Korean state media, which stated that the satellite achieved orbit about 5 minutes after launch. On this single launch, the main two-stage booster flew for 1,646 km without any significant problems. The rocket was launched eastward, passing over Japan at an altitude ...

Launch Window
In the context of spaceflight, launch period is the collection of days and launch window is the time period on a given day during which a particular rocket must be launched in order to reach its intended target. If the rocket is not launched within a given window, it has to wait for the window on the next day of the period. Launch periods and launch windows are very dependent on both the rocket's capability and the orbit to which it is going. A launch period refers to the days that the rocket can launch to reach its intended orbit. A mission could have a period of 365 days in a year, a few weeks each month, a few weeks every 26 months (e.g. Mars launch periods), or a short period time that won't be repeated. A launch window indicates the time frame on a given day in the launch period that the rocket can launch to reach its intended orbit. This can be as short as a second (referred to as an instantaneous window) or even the entire day. For operational reasons, the window almost ...

Sea Of Japan
The Sea of Japan is the marginal sea between the Japanese archipelago, Sakhalin, the Korean Peninsula, and the mainland of the Russian Far East. The Japanese archipelago separates the sea from the Pacific Ocean. Like the Mediterranean Sea, it has almost no tides due to its nearly complete enclosure from the Pacific Ocean. This isolation also affects faunal diversity and salinity, both of which are lower than in the open ocean. The sea has no large islands, bays or capes. Its water balance is mostly determined by the inflow and outflow through the straits connecting it to the neighboring seas and the Pacific Ocean. Few rivers discharge into the sea and their total contribution to the water exchange is within 1%. The seawater has an elevated concentration of dissolved oxygen that results in high biological productivity. Therefore, fishing is the dominant economic activity in the region. The intensity of shipments across the sea has been moderate owing to political issues, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Korean People's Navy
The Korean People's Army Naval Force (KPANF; Korean: 조선인민군 해군; Hanja: 朝鮮人民軍 海軍; ''Chosŏn-inmingun Haegun''; ) or the Korean People's Navy (KPN), is the naval service branch of the Korean People's Army, which contains each branch of the North Korean armed forces. There are some 780 vessels including 70 midget submarines (including the Yono-class submarine and Sang-O-class submarine), 20 Romeo-class submarines, and about 140 air cushioned landing craft. The North Korean navy is considered a brown-water (or riverine) navy and operates mainly within the 50 kilometer exclusion zone. The fleet consists of east and west coast squadrons, which cannot support each other in the event of war with South Korea. The limited range of its vessels means that, even in peacetime, it is virtually impossible for a ship on one coast to visit the other coast. History The KPN was established on 5 June 1946.

Telstar 1
Telstar 1 was a communications satellite launched by NASA on July 10, 1962. It was the satellite that allowed the first live broadcast of television images between the United States and Europe. Telstar 1 remained active for only 7 months before it prematurely failed due to Starfish Prime, a high-altitude nuclear test conducted by the United States. Although the satellite is no longer operational, it remains in Earth orbit. History The idea of transmitting information by means of satellites was hardly new. As early as October 1945, the mathematician and visionary Arthur C. Clarke published an article talking about it in the specialized magazine Wireless World. His idea was to take advantage of the immensity of space to transmit information, using a satellite system for this purpose. During the Cold War, the shock caused by the successful launch of the first artificial satellite, Sputnik 1, by the Soviets increased the United States' interest in aerospace research. Soon thereafter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dangun
Dangun (; ) or Dangun Wanggeom (; ) was the legendary founder and god-king of Gojoseon, the first Korean kingdom, around present-day Liaoning province in Northeast China and the northern part of the Korean Peninsula. He is said to be the "grandson of heaven" and "son of a bear", and to have founded the kingdom in 2333 BC. The earliest recorded version of the Dangun legend appears in the 13th-century ''Samguk Yusa'', which cites China's ''Book of Wei'' and Korea's lost historical record ''Gogi (lit. 'Ancient Record')'' (고기, ). However, it has been confirmed that there is no relevant record in the China's'' Book of Wei''. There are around seventeen religious groups that focus on the worship of Dangun. Koreans regard the day when Dangun founded Gojoseon, Korea's first dynasty, as a national holiday and call it Gaecheonjeol (개천절; 開天節). The Gaecheonjeol is 3 October. It is a religious anniversary started by Daejonggyo (대종교; 大倧教) worshipping Dangun. Gae ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China Academy Of Launch Vehicle Technology
The China Academy of Launch Vehicle Technology (CALT) is a major state-owned civilian and military space launch vehicle manufacturer in China and one of the major launch service providers in the world. CALT is a subsidiary of the larger China Aerospace Science and Technology Corporation (CASC). It was established in 1957 by Dr. Xue-Sen Qian and is headquartered in Fengtai District, Beijing. Its major contribution to China's civilian and military launch capability has been the manufacture of the Long March family of rockets. CALT has 31,600 employees and at least 13 research facilities. The current Chief Designer is Long Lehao (). CALT is also planning two spaceplanes. They would both be single-stage to space sub-orbital rocketplanes. One would be a 10-ton 4-passenger plane that would fly to 100 km at Mach 6. The other would be a 100-ton 20-passenger plane that would fly to 130 km at Mach 8. They would be equipped with liquid methane/liquid oxygen rocket engines. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intercontinental Ballistic Missile
An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than , primarily designed for nuclear weapons delivery (delivering one or more thermonuclear warheads). Conventional, chemical, and biological weapons can also be delivered with varying effectiveness, but have never been deployed on ICBMs. Most modern designs support multiple independently targetable reentry vehicles (MIRVs), allowing a single missile to carry several warheads, each of which can strike a different target. Russia, the United States, China, France, India, the United Kingdom, and North Korea are the only countries known to have operational ICBMs. Early ICBMs had limited precision, which made them suitable for use only against the largest targets, such as cities. They were seen as a "safe" basing option, one that would keep the deterrent force close to home where it would be difficult to attack. Attacks against military targets (especially hardened ones) still demande ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
