SaudiSat 5A,5B
SaudiSat 5A and 5B are two Saudi satellites were developed, manufactured and operated by the King Abdulaziz City for Science and Technology King Abdulaziz City for Science and Technology (KACST; ar, مدينة الملك عبدالعزيز للعلوم والتقنية) in Riyadh, Saudi Arabia is an organization established in 1977 as the Saudi Arabian National Center for Science & ... (KACST). The aim of these satellites is to provide high-resolution images of the planet's surface from low earth orbits which will be utilized for urban planning, monitor movements and changes on the earth's surface. The high-resolution images will also be used by government agencies for use in various fields of development. Launch SaudiSat 5A and 5B were launched on December 7, 2018, at 04:12 (UTC) by the Chinese orbital carrier rocket Long March 2D from the Jiuquan Satellite Launch Center of China.

Saudi Arabia
Saudi Arabia, officially the Kingdom of Saudi Arabia (KSA), is a country in Western Asia. It covers the bulk of the Arabian Peninsula, and has a land area of about , making it the fifth-largest country in Asia, the second-largest in the Arab world, and the largest in Western Asia and the Middle East. It is bordered by the Red Sea to the west; Jordan, Iraq, and Kuwait to the north; the Persian Gulf, Qatar and the United Arab Emirates to the east; Oman to the southeast; and Yemen to the south. Bahrain is an island country off the east coast. The Gulf of Aqaba in the northwest separates Saudi Arabia from Egypt. Saudi Arabia is the only country with a coastline along both the Red Sea and the Persian Gulf, and most of its terrain consists of arid desert, lowland, steppe, and mountains. Its capital and largest city is Riyadh. The country is home to Mecca and Medina, the two holiest cities in Islam. Pre-Islamic Arabia, the territory that constitutes modern-day Saudi Ar ...

King Abdulaziz City For Science And Technology
King Abdulaziz City for Science and Technology (KACST; ar, مدينة الملك عبدالعزيز للعلوم والتقنية) in Riyadh, Saudi Arabia is an organization established in 1977 as the Saudi Arabian National Center for Science & Technology (SANCST); in 1985, it was renamed King Abdulaziz City for Science and Technology. History In 1977, the ''Saudi Arabian National Center for Science and Technology'' (SANCST) was established, with Prof. Rida M.S. Obaid being the president. This center was created as an independent scientific organization that is responsible for the promotion of science and technology in Saudi Arabia. However, the name was later changed to ''King Abdulaziz City for Science and Technology'' (KACST). In 1987, KACST has joined the International Council for Science (ICSU) as a National Member. In 1984, Abdul Rahman Al-Athel was named as the President of the city. In 2007, Mohammed Ibrahim Al-Suwaiyel, who used to be the KACST vice president for re ...

Orbit
In celestial mechanics, an orbit is the curved trajectory of an object such as the trajectory of a planet around a star, or of a natural satellite around a planet, or of an artificial satellite around an object or position in space such as a planet, moon, asteroid, or Lagrange point. Normally, orbit refers to a regularly repeating trajectory, although it may also refer to a non-repeating trajectory. To a close approximation, planets and satellites follow elliptic orbits, with the center of mass being orbited at a focal point of the ellipse, as described by Kepler's laws of planetary motion. For most situations, orbital motion is adequately approximated by Newtonian mechanics, which explains gravity as a force obeying an inverse-square law. However, Albert Einstein's general theory of relativity, which accounts for gravity as due to curvature of spacetime, with orbits following geodesics, provides a more accurate calculation and understanding of the exact mechanics of orbi ...

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. Launch vehicles are cla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long March 2D
The Long March 2D (), also known as the Chang Zheng 2D, CZ-2D and LM-2D, is a Chinese two-stage orbital carrier rocket mainly used for launching LEO and SSO satellites. It is manufactured by the Shanghai Academy of Spaceflight Technology (SAST). It is mainly launched from areas LA-2B and LA-4 at the Jiuquan Satellite Launch Center. The Long March 2D made its maiden flight on 9 August 1992. It was initially used to launch FSW-2 and FSW-3 reconnaissance satellites. Unlike all other members of the Long March 2 rocket family, the Long March 2D is a two-stage version of the Long March 4 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 Ch ... launch vehicle.

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 ...

Satellites Of Saudi Arabia
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propuls ...

Spacecraft Launched In 2018
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] |
