Composante Spatiale Optique
Composante Spatiale Optique (CSO; English: Optical Space Component) is a French military Earth observation satellite program of third generation. It replaces the Helios 2 satellites. It is sometimes referred to as the MUltinational Space-based Imaging System for Surveillance, Reconnaissance and Observation (MUSIS program). Program history Since the launch of Helios 1A in 1995, France has developed a series of military Earth observation programs. Due to the limited lifetime of satellites, a program was launched to replace the currently operational Helios 2 satellites. This program started as a French contribution to the larger pan-European MUSIS program, and eventually became a mostly French program.

Ensemble De Lancement Soyouz
The Ensemble de Lancement Soyouz (ELS) (in English ''Soyuz Launch Complex'') is a launch complex at the Guiana Space Centre in Kourou/ Sinnamary, French Guiana. It is used by Soyuz-ST rockets: modified versions of the Soyuz-2 optimised for launch from Kourou under Soyuz at the Guiana Space Centre programme. History The first launch to use the complex occurred on 21 October 2011, when a Soyuz ST-B launched the first two Galileo In Orbit Validation spacecraft. The site's equatorial latitude allows a greater payload mass to be delivered into geosynchronous transfer orbit compared to existing Soyuz launch facilities at the Baikonur Cosmodrome in Kazakhstan. ELS is fifteen kilometres north-west of the launch facilities used by Ariane rockets. It consists of a single launch pad, with a horizontal assembly and processing facility, or MIK, located 700 metres away. As with the Soyuz launch complexes at Baikonur and Plesetsk, the pad is connected to the MIK by means of a wide gauge rai ...

Reconnaissance
In military operations, reconnaissance or scouting is the exploration of an area by military forces to obtain information about enemy forces, terrain, and other activities. Examples of reconnaissance include patrolling by troops ( skirmishers, long-range reconnaissance patrol, U.S. Army Rangers, cavalry scouts, or military intelligence specialists), ships or submarines, crewed or uncrewed reconnaissance aircraft, satellites, or by setting up observation posts. Espionage is usually considered to be different from reconnaissance, as it is performed by non-uniformed personnel operating behind enemy lines. Often called recce (British, Canadian and Australian English) or recon (American English), the word for this activity has at its root the associated verb ''reconnoitre'' or ''reconnoiter''. Etymology The word from the Middle French ''reconoissance''. Overview Reconnaissance conducted by ground forces includes special reconnaissance, armored reconnaissance, amph ...

MUSIS
The MUltinational Space-based Imaging System for Surveillance, Reconnaissance and Observation (MUSIS) is an international program including France, Italy, Belgium, Germany, Greece, and Spain, aimed at allowing the six nations to share imagery from various military satellites through a common, generic user ground segment (UGS) according to agreed rules and quota. Overview Similar to many category B projects of European Defence Agency (EDA), it is managed by OCCAR. MUSIS was intended to provide access to a number of missions intended for the 2015 timeframe: * the successor of French Hélios 2 called Composante Spatiale Optique (CSO) * the successor of German SAR-Lupe called SARah * the successor of Italian COSMO-SkyMed called COSMO Second Generation (CSG) * the Spanish wide area optical satellite SEOSat-Ingenio (formerly known as Seosat) The two systems mentioned first are entirely military whilst the two latter systems are dual-use. History MUSIS was approved in 2006 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spacecraft Launched In 2020
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] |

Ground Segment
A ground segment consists of all the ground-based elements of a space system used by operators and support personnel, as opposed to the space segment and user segment. The ground segment enables management of a spacecraft, and distribution of payload data and telemetry among interested parties on the ground. The primary elements of a ground segment are: * Ground (or Earth) stations, which provide radio interfaces with spacecraft * Mission control (or operations) centers, from which spacecraft are managed * Remote terminals, used by support personnel * Spacecraft integration and test facilities * Launch facilities * Ground networks, which allow for communication between the other ground elements These elements are present in nearly all space missions, whether commercial, military, or scientific. They may be located together or separated geographically, and they may be operated by different parties. Some elements may support multiple spacecraft simultaneously. Elements Gr ...

Pleiades (satellite)
The Pleiades (), also known as The Seven Sisters, Messier 45 and other names by different cultures, is an asterism and an open star cluster containing middle-aged, hot B-type stars in the north-west of the constellation Taurus. At a distance of about 444 light years, it is among the nearest star clusters to Earth. It is the nearest Messier object to Earth, and is the most obvious cluster to the naked eye in the night sky. It is also observed to house the reflection nebula NGC 1432, an HII Ionized region. The cluster is dominated by hot blue luminous stars that have formed within the last 100 million years. Reflection nebulae around the brightest stars were once thought to be left over material from their formation, but are now considered likely to be an unrelated dust cloud in the interstellar medium through which the stars are currently passing. This dust cloud is estimated to be moving at a speed of approximately 18 km/s relative to the stars in the cluster. Computer sim ...

SPOT (satellite)
SPOT (french: Satellite Pour l’Observation de la Terre, lit. "Satellite for observation of Earth") is a commercial high-resolution optical Earth imaging satellite system operating from space. It is run by Spot Image, based in Toulouse, France. It was initiated by the CNES (''Centre national d'études spatiales'' – the French space agency) in the 1970s and was developed in association with the SSTC (Belgian scientific, technical and cultural services) and the Swedish National Space Board (SNSB). It has been designed to improve the knowledge and management of the Earth by exploring the Earth's resources, detecting and forecasting phenomena involving climatology and oceanography, and monitoring human activities and natural phenomena. The SPOT system includes a series of satellites and ground control resources for satellite control and programming, image production, and distribution. Earlier satellites were launched using the European Space Agency's Ariane 2, 3, and 4 rocket ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellite Bus
A satellite bus (or spacecraft bus) is the main body and structural component of a satellite or spacecraft, in which the payload and all scientific instruments are held. Bus-derived satellites are opposed to specially produced satellites. Bus-derived satellites are usually customized to customer requirements, for example with specialized sensors or transponders, in order to achieve a specific mission. They are commonly used for geosynchronous satellites, particularly communications satellites, but are also used in spacecraft which occupy lower orbits, occasionally including low Earth orbit missions. Examples Some satellite bus examples include: * Boeing DS&S 702 * Lockheed Martin Space Systems A2100 * Alphabus * INVAP ARSAT-3K * Airbus D&S Eurostar * ISRO's I-1K, I-2K, I-3K, I-4K, I-6K, and Indian Mini Satellite bus * NASA Ames MCSB * SSL 1300 * Orbital ATK GEOStar * Mitsubishi Electric DS2000 * Spacecraft bus of the James Webb Space Telescope * SP ...
