Chollima-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 ...

Malligyong-1
Malligyong-1 () is a type of North Korean reconnaissance satellite. The mission's first two launch attempts failed, with the third one succeeding on 21 November 2023. This was also the first successful flight of North Korea's new launch vehicle, the Chollima-1. Description Malligyong-1 is North Korea's first spy satellite. It is in a sun-synchronous orbit at about altitude, and will provide a global optical imaging surveillance capability of several countries. The resolution of the imaging capability is not generally known, but according to Daily NK, Malligyong-1's imagery resolution is lower than the resolution of Google's satellite imagery. Daily NK also stated that the satellite used a Japanese camera, but it was alleged to be not capable of providing meaningful military surveillance data. History First attempt The first launch attempt occurred on 31 May 2023. The second stage of the launch vehicle, Chollima-1, ignited too early into the mission, causing the mission to ...

Hwasong-17
The Hwasong-17 () is a North Korean two-stage intercontinental ballistic missile, first unveiled on 10 October 2020, at the 75th anniversary of the founding of the Workers' Party of Korea parade. The Japanese Ministry of Defence estimates its operational range at or more. Unlike its predecessors, the Hwasong-17 may be capable of carrying multiple warheads. North Korea claimed the first Hwasong-17 was successfully launched on 24 March 2022. Some western analysts instead believe the 24 March launch was an earlier missile design, and a later test that took place on 18 November 2022 was the first successful test launch. Description The Hwasong-17 is assumed to be a two-stage, Liquid-propellant rocket, liquid-fueled road-mobile ICBM carried by a 22-wheeled transporter erector launcher (TEL) vehicle. The first stage uses two RD-250-based engines. Based on images released by North Korea, the missile's mass, length and diameter itself are judged to be about , and respectively. The ...

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 ...

Chollima Movement
The Chollima Movement () was a state-sponsored Stakhanovite movement in North Korea intended to promote rapid economic development. Launched in 1956 or 1958, the movement emphasized "ideological incentives to work harder" and the personal guidance of Kim Il Sung rather than rational modes of economic management. Origin The term Chollima originates from the Chinese mythological flying horse. The word Chollima can be translated as "thousand-li horse," referring to its ability to travel 1,000 li (500 kilometers or 310 miles) in a single day. It also was said that no mortal man could ride it. It is known for accomplishing the most difficult tasks and having led heroes to victory. This idea of Chollima was used by Kim Il Sung to energize the workers in North Korea to bring the country out of the rubble of the Korean War to obtain a better life and a more prosperous country in a short amount of time. Kim Il Sung first introduced the term Chollima in December 1956,Jefferies, "North ...

Unha
The Unha (, "Galaxy") is a North Korean expendable launch system, expendable launch vehicle, carrier rocket, which partially utilizes the same delivery system as the Taepodong-2 orbital launch system. History North Korea's first orbital space launch attempt occurred on 31 August 1998, and was unsuccessful. This launch attempt was performed by a Paektusan (rocket), Paektusan-1 rocket, which used a solid motor third stage, a Scud missile, Scud-missile-based second stage, and a Hwasong-7 (Nodong-1) based first stage. Hwasong-7 was a North Korean-developed stage thought to be a scale-up of the old Soviet Scud missile. The Paektusan-1 stood tall, was in diameter, and weighed about 21 tonnes. Vehicle description The Unha's first stage consists of four clustered Nodong motors, which themselves are enlarged Scud motors. The second stage was initially thought to be based on the SS-N-6, although it, too, is now believed to be based on Scud technology. The third and last stage might ...

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 ...

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 ...

Nuri (rocket)
Nuri (; , meaning 'world' in native Korean language, Korean), also known as KSLV-II (Korean Space Launch Vehicle-II), is a Multistage rocket, three-stage launch vehicle, the second one developed by South Korea and the successor to Naro-1 (KSLV-1). It is developed by Korea Aerospace Research Institute (KARI). All three stages use indigenously developed launch vehicle engines, making Nuri the first indigenously developed South Korean orbital launch vehicle (the Naro-1 launch vehicle used a Russian-made first stage). History The South Korean government has striving to develop relatively cheap and reliable rockets competitive enough for the commercial launch market. On 21 October 2021, Nuri made its initial orbital launch attempt at 08:00 UTC and it launched a dummy satellite payload into what was planned to be a Sun-synchronous orbit (SSO). However, despite the payload reaching the targeted apogee (700 km), the third stage shut down about 46 seconds earlier than planned a ...

Medium-lift Launch Vehicle
A medium-lift launch vehicle (MLV) is a rocket launch vehicle that is capable of lifting between by NASA classification or between by Russian classification of payload into low Earth orbit (LEO).50t payloads" An MLV is between a small-lift launch vehicle and a heavy-lift launch vehicle. Medium-lift vehicles comprise the majority of orbital launches , with both the Soyuz and Falcon 9 having launched several hundred times. History Soviet Union and Russia The Soviet R-7 family was based on the world's first intercontinental ballistic missile (ICBM). Sputnik was a small-lift derivative that carried the first satellite into orbit, and the R-7 design quickly grew in capacity, with Luna launching in 1958. The 1960s saw the R-7 series continue to develop, with Vostok 1 carrying the first human into space, Voskhod carrying multiple crew members, and the first Soyuz. , Soyuz variants are still operational and have launched over 1,100 times. The R-7 family has launched more times ...
