Tonghae Satellite Launching Ground
The Tonghae Satellite Launching Ground(동해위성발사장), 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 1980s, 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 u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocket
A rocket (from , and so named for its shape) is a vehicle that uses jet propulsion to accelerate without using any surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Territorial Waters
Territorial waters are informally an area of water where a sovereign state has jurisdiction, including internal waters, the territorial sea, the contiguous zone, the exclusive economic zone, and potentially the extended continental shelf (these components are sometimes collectively called the maritime zones). In a narrower sense, the term is often used as a synonym for the territorial sea. Vessels have different rights and duties when passing through each area defined by the United Nations Convention on the Law of the Sea (UNCLOS), one of the most ratified treaties. States cannot exercise their jurisdiction in waters beyond the exclusive economic zone, which are known as the high seas. Baseline Normally, the baseline is the low-water line along the coast as marked on large-scale charts that the coastal state recognizes. This is either the low-water mark closest to the shore or an unlimited distance from permanently exposed land, provided that some portion of elevations ...

Sohae Satellite Launching Station
Sohae Satellite Launching Station (, 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 w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liquid Fuel
Liquid fuels are combustible or energy-generating molecules that can be harnessed to create mechanical energy, usually producing kinetic energy; they also must take the shape of their container. It is the fumes of liquid fuels that are flammable instead of the fluid. Most liquid fuels in widespread use are derived from fossil fuels; however, there are several types, such as hydrogen fuel (for automotive uses), ethanol, and biodiesel, which are also categorized as a liquid fuel. Many liquid fuels play a primary role in transportation and the economy. Liquid fuels are contrasted with solid fuels and gaseous fuels. General properties Some common properties of liquid fuels are that they are easy to transport, and can be handled with relative ease. Physical properties of liquid fuels vary by temperature, though not as greatly as for gaseous fuels. Some of these properties are: flash point, the lowest temperature at which a flammable concentration of vapor is produced; fire point, the ...

Launch Pad
A launch pad is an above-ground facility from which a rocket-powered missile or space vehicle is vertically launched. The term ''launch pad'' can be used to describe just the central launch platform (mobile launcher platform), or the entire complex (launch complex). The entire complex will include a ''launch mount'' or ''launch platform'' to physically support the vehicle, a service structure with umbilicals, and the infrastructure required to provide liquid-propellant rocket, propellants, cryogenic fluids, electrical power, communications, telemetry, rocket assembly, payload processing, storage facilities for propellants and gases, equipment, access roads, and drainage. Most launch pads include fixed service structures to provide one or more access platforms to assemble, inspect, and maintain the vehicle and to allow access to the spacecraft, including the loading of crew. The pad may contain a Flame deflector, flame deflection structure to prevent the intense heat of the roc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kwangmyŏngsŏng-2
Kwangmyŏngsŏng-2 (, meaning Bright Star-2 or Lode Star-2) was a satellite launched by North Korea on April 5, 2009. Prior to the launch, concern was raised by other nations, particularly the United States, South Korea and Japan, that the launch would test technology that could be used in the future to launch an intercontinental ballistic missile. The launch of the rocket was sharply condemned by the United States and the European Union, while the People's Republic of China and Russia urged restraint. On April 13, 2009, the United Nations Security Council issued a Presidential Statement condemning the launch as a violation of United Nations Security Council Resolution 1718 (2006). One day after, on April 14, 2009, North Korea called the Presidential Statement an infringement on a country's right for space exploration embodied in the Outer Space Treaty and withdrew from Six Party Talks. Etymology The name "Kwangmyŏngsŏng" is in reference to a lodestar. According to some, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paektusan (rocket)
Taepodong-1 () was the external designation given to 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 ...

Kwangmyŏngsŏng-1
Kwangmyŏngsŏng-1 (, 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 foundation. 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 satellite. The mass of the satellite is unclear, with estima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
