Long March (rocket Family)
The Long March rockets are a family of expendable launch system rockets operated by the China Aerospace Science and Technology Corporation. The rockets are named after the Chinese Red Army's 1934–35 Long March military retreat during the Chinese Civil War. The Long March series has performed more than 350 launches, including missions to low-Earth orbit, sun-synchronous orbit, geostationary transfer orbit, and Earth-moon transfer orbit. The new-generation carrier rockets, Long March 5, Long March 6, Long March 7, Long March 11, and Long March 8, have made their maiden flights. Among them, the Long March 5 has a low-Earth orbit carrying capacity of 25,000 kilograms, and a geosynchronous transfer orbit carrying capacity of 14,000 kilograms. History China used the Long March 1 rocket to launch its first satellite, Dong Fang Hong I, Dong Fang Hong 1 (lit. "The East is Red 1"), into low Earth orbit on 24 April 1970, becoming the fifth nation to achieve independent launch capabi ...

Space Program Of The People's Republic Of China
The space program of the People's Republic of China is directed by the China National Space Administration (CNSA). China's space program has overseen the development and launch of ballistic missiles, thousands of artificial satellites, manned spaceflight, an indigenous space station, and has stated plans to explore the Moon, Mars, and the broader Solar System. The technological roots of the Chinese space program trace back to the 1950s, when, with the help of the newly-allied Soviet Union, China began development of its first ballistic missile and rocket programs in response to the perceived American (and, later, Soviet) threats.DF-1 GlobalSecurity.org.

Reconnaissance Satellite
A reconnaissance satellite or intelligence satellite (commonly, although unofficially, referred to as a spy satellite) is an Earth observation satellite or communications satellite deployed for military or intelligence applications. The first generation type (i.e., Corona and Zenit) took photographs, then ejected canisters of photographic film which would descend back down into Earth's atmosphere. Corona capsules were retrieved in mid-air as they floated down on parachutes. Later, spacecraft had digital imaging systems and downloaded the images via encrypted radio links. In the United States, most information available about reconnaissance satellites is on programs that existed up to 1972, as this information has been declassified due to its age. Some information about programs before that time is still classified information, and a small amount of information is available on subsequent missions. A few up-to-date reconnaissance satellite images have been declassified o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fanhui Shi Weixing-0
The Fanhui Shi Weixing () series of satellites was China's first reconnaissance satellite program. The satellites were used for military reconnaissance and civilian imagery tasks and completed 23 missions between November 1974 and April 2016. There were four generations of the Fanhui Shi Weixing (FSW) satellites: FSW-0 from 1974 to 1987; FSW-1 from 1987 to 1993; FSW-2 from 1992 to 1996; and FSW-3 from 2003 to 2005. Two derivative models, the Shijian-8 (SJ-8) and Shijian-10 (SJ-10), were developed and launched as 'seed satellites' conducting bioastronautic experiments for the Chinese Ministry of Agriculture. All FSW-series satellites were launched into orbit using Long March rockets from the Jiuquan Satellite Launch Center ( JSLC). The successful recovery of the an FSW-0 recoverable satellite in 1974 established China as the third nation to launch and recover a satellite following the United States and Soviet Union. This success served as the basis for the second Chinese crewe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long March 2
Long March 2 rocket family or Chang Zheng 2 rocket family as in Chinese pinyin is an expendable launch system operated by the People's Republic of China. The rockets use the abbreviations LM-2 family for export, and CZ-2 family within China, as "Chang Zheng" means "Long March" in Chinese pinyin. They are part of the larger Long March rocket family. Development and design falls mostly under the auspices of the China Academy of Launch Vehicle Technology (CALT). History Long March 2 was the original model in the Long March 2 rocket family, which was derived from China's first ICBM, the DF-5. The development work began in 1970. The first rocket was launched on November 5, 1974, but the launch failed. After the failed first launch of Long March 2, its design was slightly modified and designated as Long March 2A. Long March 2A was successfully launched in 1975. The production of the Long March 2A ended in 1979. Long March 2C and Long March 2D's first launches occurred ...

STEM Fields
Science, technology, engineering, and mathematics (STEM) is an umbrella term used to group together the distinct but related technical disciplines of science, technology, engineering, and mathematics. The term is typically used in the context of education policy or curriculum choices in schools. It has implications for workforce development, national security concerns (as a shortage of STEM-educated citizens can reduce effectiveness in this area) and immigration policy. There is no universal agreement on which disciplines are included in STEM; in particular whether or not the ''science'' in STEM includes social sciences, such as psychology, sociology, economics, and political science. In the United States, these are typically included by organizations such as the National Science Foundation (NSF), which deals with all matters concerning science and new discoveries in science as it affects development, research, and innovations, the Department of Labor's O*Net online database for ...

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. In this regar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Technology
Technology is the application of knowledge to reach practical goals in a specifiable and reproducible way. The word ''technology'' may also mean the product of such an endeavor. The use of technology is widely prevalent in medicine, science, industry, communication, transportation, and daily life. Technologies include physical objects like utensils or machines and intangible tools such as software. Many technological advancements have led to societal changes. The earliest known technology is the stone tool, used in the prehistoric era, followed by fire use, which contributed to the growth of the human brain and the development of language in the Ice Age. The invention of the wheel in the Bronze Age enabled wider travel and the creation of more complex machines. Recent technological developments, including the printing press, the telephone, and the Internet have lowered communication barriers and ushered in the knowledge economy. While technology contributes to econom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low Earth Orbit
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth. The term ''LEO region'' is also 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, are carefully tracked since they present a collision risk to the many LEO satellites. All crewed space stations to date have been within LEO. From 1968 to 1972, the Apollo program's lunar missions sent humans beyond LEO. Since the end of the Apollo program, no human spaceflights have been beyond LEO. Defining characteristics A wide variety of sources define LEO in terms of altitude. The altitude of an object in an elliptic orbit can vary significantly along the orbit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dong Fang Hong 1
''Dong Fang Hong 1'' (), in the western world also known as China 1 or PRC 1, was the first space satellite of the People's Republic of China (PRC), launched successfully on 24 April 1970 as part of the PRC's Dongfanghong space satellite program. It was a part of the " Two Bombs, One Satellite" program. At , it was heavier than the first satellites of other countries. The satellite carried a radio transmitter which broadcast the ''de facto'' national anthem of the same name. The broadcast lasted for 20 days while in orbit. It was developed under the direction of Qian Xuesen, dean of the China Academy of Space Technology (CAST). At the time, a total of five identical satellites were created. The first satellite launched successfully. The academy formulated a "Three-Satellite Plan" consisting of ''Dongfanghong 1'', re-entry satellites, and geosynchronous orbit communications satellites.
