FB-1
The Feng Bao 1 (), also known as FB-1, was a Chinese carrier rocket launched between 1972 and 1981. It was replaced by the nearly identical Long March 2, which had been developed at the same time for political reasons related to China's Cultural Revolution. The Feng Bao was derived from the DF-5 missile. Eleven were launched, of which four failed. Launches occurred from LA-2B at the Jiuquan Satellite Launch Centre Jiuquan Satellite Launch Center (JSLC; also known as Shuangchengzi Missile Test Center; Launch Complex B2; formally Northwest Comprehensive Missile Testing Facility (); Base 20; 63600 Unit) is a Chinese space vehicle launch facility (spac ....

Jiuquan Satellite Launch Center
Jiuquan Satellite Launch Center (JSLC; also known as Shuangchengzi Missile Test Center; Launch Complex B2; formally Northwest Comprehensive Missile Testing Facility (); Base 20; 63600 Unit) is a Chinese space vehicle launch facility (spaceport) located in the Gobi Desert, Inner Mongolia. It is part of the Dongfeng Aerospace City (Base 10). Although the facility is geographically located within Ejin Banner of Inner Mongolia's Alxa League, it is named after the nearest city, Jiuquan in Gansu Province. The launch center straddles both sides of the Ruo Shui river. History It was founded in 1958, the first of China's four spaceports. As with all Chinese launch facilities, it is remote and generally closed to foreigners. The Satellite Launch Center is a part of Dongfeng Space City (), also known as ''Base 10'' () or ''Dongfeng base'' (). The Dongfeng site also includes People's Liberation Army Air Force (PLAAF) test flight facilities, a space museum and a so-called marty ...

Carrier Rocket
A launch vehicle or carrier rocket is a rocket designed to carry a payload (spacecraft or satellites) from the Earth's surface to outer space. Most launch vehicles operate from a launch pad, launch pads, supported by a missile launch control center, launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to large operating costs. An orbital spaceflight, orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital spaceflight, Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles are multistage rockets which use chemical propellants such as Solid-propellant rocket, solid fuel, liquid hydrogen, kerosene, liquid oxygen, or Hypergolic propellants.

DF-5
The Dongfeng 5 () or DF-5 is a second-generation two stage Chinese intercontinental ballistic missile. It has a length of 32.6 m and a diameter of 3.35 m. It weighs in at 183,000 kilograms and it has an estimated range of 12,000 to 15,000 kilometers. The DF-5 had its first flight in 1971 and was in operational service 10 years later. One of the limitations of the missile is that it takes between 30 and 60 minutes to fuel. The DF-5 is due to be replaced by the solid-fuelled DF-41. Around 2015, the newest variant DF-5B force are believed to have received a MIRV upgrade; according to ''Business Insider'', with DF-5B: "China has the ability to deliver nuclear warheads nearly anywhere on earth (outside of South America, at least)". History The DF-5 was designed under the leadership of Tu Shou'e 守锷 at the China Academy of Launch Technology (CALT); Li Xu'e 绪鄂served as deputy chief designer. The missile was produced at the China's Factory 211 (Capital Astronautics Co. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shijian
Shijian (, abbr. "SJ") is a series of satellites built and operated by the People's Republic of China. Some Shijian-series satellites have drawn significant concerns from the United States government and space observers who cite unannounced launches, undisclosed sub-satellites deployed in orbit, unusual orbital maneuvers, and demonstrated rendezvous proximity operations (RPO) including the close inspection and towing of other satellites. Little is known about the series and what differentiates it from other experimental satellite series launched by China such as the Chuangxin () series or Shiyan () series. The China Aerospace Studies Institute of the United States Air Force asserts that Shiyan-series satellites play an earlier role in the systems development process testing various new technologies on a single bus while Shijan-series satellites are used to develop operational best practices and optimize the technologies previously tested on Shiyan-series satellites.

Apogee
An apsis (; ) is the farthest or nearest point in the orbit of a planetary body about its primary body. For example, the apsides of the Earth are called the aphelion and perihelion. General description There are two apsides in any elliptic orbit. The name for each apsis is created from the prefixes ''ap-'', ''apo-'' (), or ''peri-'' (), each referring to the farthest and closest point to the primary body the affixing necessary suffix that describes the primary body in the orbit. In this case, the suffix for Earth is ''-gee'', so the apsides' names are ''apogee'' and ''perigee''. For the Sun, its suffix is ''-helion'', so the names are ''aphelion'' and ''perihelion''. According to Newton's laws of motion, all periodic orbits are ellipses. The barycenter of the two bodies may lie well within the bigger body—e.g., the Earth–Moon barycenter is about 75% of the way from Earth's center to its surface. If, compared to the larger mass, the smaller mass is negligible (e.g., f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suborbital
A sub-orbital spaceflight is a spaceflight in which the spacecraft reaches outer space, but its trajectory intersects the atmosphere or surface of the gravitating body from which it was launched, so that it will not complete one orbital revolution (it does not become an artificial satellite) or reach escape velocity. For example, the path of an object launched from Earth that reaches the Kármán line (at ) above sea level), and then falls back to Earth, is considered a sub-orbital spaceflight. Some sub-orbital flights have been undertaken to test spacecraft and launch vehicles later intended for orbital spaceflight. Other vehicles are specifically designed only for sub-orbital flight; examples include crewed vehicles, such as the X-15 and SpaceShipOne, and uncrewed ones, such as ICBMs and sounding rockets. Flights which attain sufficient velocity to go into low Earth orbit, and then de-orbit before completing their first full orbit, are not considered sub-orbital. Exam ...
