Chŏllima 1
Chollima-1 () is a North Korean launch vehicle. It will be used by North Korea to launch satellites into orbit. The rocket is launched from a coastal launch platform in the Sohae Satellite Launching Station. The rocket has been developed to compete with the South Korean Nuri rocket. Description Chollima-1 is a three-stage rocket. This new rocket, based on images released by North Korea, appears to be a different launcher from those of the previous Unha family. It appears to be abandoning the Scud heritage and take a design based on the recent Hwasong-15 and 17 ICBMs with advanced rocket engines based on the suspiciously acquired Soviet RD-250. According to 38 North, the Chollima-1's first stage is based on the Hwasong-17. Although the capabilities of the launch vehicle are not public, Chollima-1 appears to be a medium-lift launch vehicle for launching small satellites into low Earth orbit, and the payload mass for its maiden flight was estimated to be around to . Similarly, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stakhanovite Movement
The Stakhanovite movement was a mass cultural movement for workers established by the Communist Party in the 1930s Soviet Union. Its promoters encouraged the rationalization of workplace processes—i.e., increased production goals—while promoting socialist emulation. The Stakhanovites modeled themselves after the mythic productivity of the Russian coal miner Alexei Stakhanov. As frontline workers they took pride in their aspirations to work harder and more efficiently than was required by ad hoc norms; thereby they saw themselves as contributing to the common good and strengthening the socialist state. The Party started the 'movement' in the coal industry and then applied it to other industries across the Soviet Union. Initially popular, it eventually encountered resistance as the pressures for greater productivity placed increased and unrealistic demands on workers. History The Stakhanovite movement was established and developed by the Soviet Communist Party; it was s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Indian Express
''The Indian Express'' is an English-language Indian daily newspaper founded in 1932 by P. Varadarajulu Naidu. It is headquartered in Noida, owned by the ''Indian Express Group''.

Low Earth Orbit
A low Earth orbit (LEO) is an geocentric orbit, orbit around Earth with a orbital period, period of 128 minutes or less (making at least 11.25 orbits per day) and an orbital eccentricity, eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, peaking in number at an altitude around , while the farthest in LEO, before medium Earth orbit (MEO), have an altitude of 2,000 km, about one-third of the Earth radius, radius of Earth and near the beginning of the Van Allen radiation belt#Inner belt, inner Van Allen radiation belt. The term ''LEO region'' is used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital spaceflight, sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. No human spaceflights other than the lunar missions of the Apollo program (1968-1972) have gone beyond L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Small Satellite
A small satellite, miniaturized satellite, or smallsat is a satellite of low mass and size, usually under . While all such satellites can be referred to as "small", different classifications are used to categorize them based on mass. Satellites can be built small to reduce the large economic cost of launch vehicles and the costs associated with construction. Miniature satellites, especially in large numbers, may be more useful than fewer, larger ones for some purposes – for example, gathering of scientific data and radio relay. Technical challenges in the construction of small satellites may include the lack of sufficient power storage or of room for a propulsion system. Rationales One rationale for miniaturizing satellites is to reduce the cost; heavier satellites require larger rockets with greater thrust that also have greater cost to finance. In contrast, smaller and lighter satellites require smaller and cheaper launch vehicles and can sometimes be launched in mult ...

RD-250
The RD-250 (, GRAU index: 8D518) is the base version of a dual-nozzle family of liquid-fuel rocket engines, burning a hypergolic mixture of unsymmetrical dimethylhydrazine (UDMH) fuel with dinitrogen tetroxide () oxidizer in a gas-generator open cycle. The RD-250 was developed by OKB-456 for Yangel's PA Yuzhmash ICBM, the R-36 (8K67). Its variations were also used on the Tsyklon-2 and Tsyklon-3 launch vehicles. It was supposed to be used on the Tsyklon-4, but since the cancellation of the project it should be considered as out of production. Versions The engine has seen different versions made: * RD-250 (GRAU index: 8D518): Base engine of the family. Used on the R-36. A bundle of three RD-250 form the RD-251 cluster. * RD-250P (GRAU index: 8D518P): Improved version of the RD-250. Used on the R-36P.

Hwasong-15
The Hwasong-15 () is an intercontinental ballistic missile developed by North Korea. It had its maiden flight on 28 November 2017, around 3 a.m. local time. It is the first ballistic missile developed by North Korea that is theoretically capable of reaching all of the United States' mainland. Design Missile Judged from images released by North Korea, the Hwasong-15 is in length, wide and has a body mass of about . Based on its trajectory and distance, the missile would have a range of more than – more than enough to reach Washington D.C. and the rest of the United States, albeit, according to the Union of Concerned Scientists, probably with a reduced payload. Several important US allies, including the United Kingdom, France and Australia, also lie within the missile's theoretical range, which covers most of Earth's land masses except South America, the Caribbean, and the majority of Antarctica. However, in the first flight, North Korea fired Hwasong-15 using lofted traject ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
