Diamant
The Diamant rocket (French for "diamond") was the first exclusively French expendable launch system and at the same time the first satellite launcher not built by either the United States or USSR. As such, it has been referred to as being a key predecessor for all subsequent European launcher projects. During 1962, development of the Diamant commenced as the inaugural spacecraft project of France's space agency, the Centre National d'Études Spatiales (CNES). As a project, it was derived from the military program ''Pierres précieuses'' (fr.: gemstones) that included the five prototypes Agate, Topaze, Emeraude, Rubis and Saphir (Agate, Topaz, Emerald, Ruby and Sapphire), and drew heavily upon the knowledge and technologies that had been previously developed. On 26 November 1965, the Diamant A performed its maiden flight. Out of a total of 12 launch attempts to be performed between 1965 and 1975, 9 of these were successful. Most notably, on 26 November 1965, the Diamant was u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centre Interarmées D'essais D'engins Spéciaux
The Interarmy Special Vehicles Test Centre (CIEES) (French language, French: Centre Interarmées d'Essais d'Engins Spéciaux) was France's first space launch and ballistic missile testing facility. Outside France, the facility is often referred to by the name of the nearest town, Hammaguir (also called Hammaguira). It was established on 24 April 1947, by ministerial decree as the Special Weapons Test Center (CEES, ''Centre d'essais d'engins spéciaux'') for use by the French Army. In 1948, it was turned over to the French Air Force, who renamed it CIEES. Its remote location in the middle of the Saharan Desert and its relative closeness to the Equator (compared with Metropolitan France) made it an attractive launch site for missiles and orbital rockets. History The origins of CIEES and the French missile and space program date to the end of the Second World War. On 12 June 1945, less than a month after V-E Day, the War Department ordered the study of self-propelled projectiles (rock ...

25143 Itokawa
25143 Itokawa (provisional designation ) is a sub-kilometer near-Earth object of the Apollo group and a potentially hazardous asteroid. It was discovered by the LINEAR program in 1998 and later named after Japanese rocket engineer Hideo Itokawa. The peanut-shaped S-type asteroid has a rotation period of 12.1 hours and measures approximately in diameter. Due to its low density and high porosity, Itokawa is considered to be a rubble pile, consisting of numerous boulders of different sizes rather than of a single solid body. It was the first asteroid to be the target of a sample return mission, the Japanese space probe ''Hayabusa'', which collected more than 1500 regolith dust particles from the asteroid's surface in 2005. After its return to Earth in 2010, the mineralogy, petrography, chemistry, and isotope ratios of these particles have been studied in detail, providing insights into the evolution of the Solar System. Itokawa was the smallest asteroid to be photographed and vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astérix (satellite)
''Astérix'' or A-1 (initially conceptualized as FR.2 or FR-2) is the first French satellite. It was launched on 26 November 1965 by a Diamant A rocket from the CIEES launch site at Hammaguir, Algeria. With ''Astérix'', France became the sixth country to have an artificial satellite and the third country to launch a satellite on its own rocket. Its main purpose was to test the Diamant launcher, though it was also designed to study the ionosphere. ''Astérix'' continues to orbit Earth as of 2022 and is expected to remain in orbit for centuries. Background The French space agencies Centre national d'études spatiales (CNES) and Centre national d'études des télécommunications (CNET) were developing ''Astérix'' concurrent with FR-1, another satellite, as early as 1963. FR-1 was the first step of an ambitious French plan to launch six FR-series satellites, each meant to study a different aspect of the Earth's atmosphere. FR-1 was generally designed to study the Earth's magnet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Launch Site
A spaceport or cosmodrome is a site for launching or receiving spacecraft, by analogy to a seaport for ships or an airport for aircraft. The word ''spaceport'', and even more so ''cosmodrome'', has traditionally been used for sites capable of launching spacecraft into orbit around Earth or on interplanetary trajectories. However, rocket launch sites for purely sub-orbital flights are sometimes called spaceports, as in recent years new and proposed sites for suborbital human flights have been frequently referred to or named "spaceports". Space stations and proposed future bases on the Moon are sometimes called spaceports, in particular if intended as a base for further journeys. The term rocket launch site is used for any facility from which rockets are launched. It may contain one or more launch pads or suitable sites to mount a transportable launch pad. It is typically surrounded by a large safety area, often called a rocket range or missile range. The range includes the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Provinces Of Algeria
Algeria, since December 18, 2019, is divided into 58 wilaya, wilayas (province, provinces). Prior to December 18, 2019, there were 48 provinces.

Satellite Geodesy
Satellite geodesy is geodesy by means of artificial satellites—the measurement of the form and dimensions of Earth, the location of objects on its surface and the figure of the Earth's gravity field by means of artificial satellite techniques. It belongs to the broader field of space geodesy. Traditional astronomical geodesy is ''not'' commonly considered a part of satellite geodesy, although there is considerable overlap between the techniques. The main goals of satellite geodesy are: # Determination of the figure of the Earth, positioning, and navigation (geometric satellite geodesy) # Determination of geoid, Earth's gravity field and its temporal variations (dynamical satellite geodesy or satellite physical geodesy) # Measurement of geodynamical phenomena, such as crustal dynamics and polar motion Satellite geodetic data and methods can be applied to diverse fields such as navigation, hydrography, oceanography and geophysics. Satellite geodesy relies heavily on orbital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
