Algeria National Space Programs
The National Space Program (PSN) horizons 2020 planned to put in place space infrastructures, space systems and increase the specialized human resources in space technologies. Among the space systems planned in the PSN are Algeria's satellites ( Alsat-2A, Alsat -2b, Alsat -3, Alsat -4, African Resource Management ''ARM'' and the communications satellite Alcomsat-1), of which a significant number should be partly or totally integrated in the Algerian center for satellite development "''CDS''". CDS offers the technological environment for national competence to develop the future Algerian satellite systems. Algeria's objectives is to make of space tools a powerful instrument in national prosperity in the fields of earth observation, meteorology and communications. CDS in the National Space Program CDS comprises: *A satellite integration hall: a clean room of 27 meters x 11 meters *A satellite environmental tests building. *Rooms and equipment for the components storage, cleaning ...

Algerian Space Agency
The Algerian Space Agency (ASAL; french: Agence spatiale algérienne, links=, lit=, translit=, label=, ar, الوكالة الفضائية الجزائرية, links=, lit=, translit=Al-Wakāla al-Faḍā’iyya al-Jazā’iriyya), was established on in Bouzareah, Algiers. The agency is in charge of the Algerian space program, and has flown five different satellites. Objectives The Algerian Space Agency wants to: * Propose to the Government the elements of a national strategy in the field of space activity and ensure their implementation * Establish a space infrastructure to strengthen national capacities * Implement the annual and multi annual programs to develop national space activities related to the various sectors concerned and to ensure the monitoring and evaluation * Propose to the Government best suited to national concerns and provide space systems, on behalf of the state, their design, implementation and operation * Provide the Government a policy of bilateral a ...

Long March 3B
The Long March 3B (, ''Chang Zheng 3B''), also known as the CZ-3B and LM-3B, is a Chinese orbital launch vehicle. Introduced in 1996, it is launched from Launch Area 2 and 3 at the Xichang Satellite Launch Center in Sichuan. A three-stage rocket with four strap-on liquid rocket boosters, it is currently the second most powerful member of the Long March (rocket family), Long March rocket family after the Long March 5 and the heaviest of the Long March 3 rocket family, and is mainly used to place communications satellites into geosynchronous orbits. An enhanced version, the Long March 3B/E or G2, was introduced in 2007 to increase the rocket's geostationary transfer orbit (GTO) cargo capacity and lift heavier geosynchronous orbit (GEO) communications satellites. The Long March 3B also served as the basis for the medium-capacity Long March 3C, which was first launched in 2008. , the Long March 3B, 3B/E and 3B/G5 have conducted 82 successful launches, plus 2 failures and 2 partial ...

Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications sate ...

Spacecraft Launched In 2017
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit (space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...
