ConeXpress
ConeXpress was a concept orbital life extension vehicle project that was co-funded by ESA and Orbital Recovery Ltd. The Ariane-5 interface cone structure would be the basis. ConeExpress satellites would travel to the Geostationary orbit, lock on to satellites that have run out of fuel and extend their lives. It was conceived to provide the operators of geostationary communications satellites with an opportunity to extend the revenue-earning life of select space assets by up to 10 years. Docking The onboard docking equipment consisted of a capture tool that inserts a probe into the throat of the apogee motor of the Client satellite, locks itself to the throat by expanding the crown of the probe, and pulls the Client satellite back towards it by retracting the probe. This process is reversed for undocking. ConeXpress was sized to work with dock with satellites weighing up to .

Con Express
''Con Express'' is a 2002 direct-to-video action film with a political edge, starring by Arnold Vosloo, Sean Patrick Flanery, and Tim Thomerson. It was written by Paul A. Birkett and Terry Cunningham and directed by Cunningham. The movie uses film footage from Runaway Train (1985) and Cliffhanger (1993). Plot US Customs agent Alex Brooks uncovers the plot of Russian arms dealers who planned to smuggle nerve gas into the U.S. In order to avoid publicity, the boss of the small customs station in Alaska decides that the dangerous barrels should be sent to a safe compound by train. Meanwhile, a Russian General turned terrorist who is responsible for the smuggling, Simeonov, is being delivered via plane to Washington until a group of his henchmen rescue him. Brooks and the Russian agent Natalya are the only people capable of stopping Simeonov and his group of terrorists from keeping control of the train carrying the deadly nerve gas.

Geostationary
A geostationary orbit, also referred to as a geosynchronous equatorial orbit''Geostationary orbit'' and ''Geosynchronous (equatorial) orbit'' are used somewhat interchangeably in sources. (GEO), is a circular geosynchronous orbit in altitude above Earth's equator ( in radius from Earth's center) and following the direction of Earth's rotation. An object in such an orbit has an orbital period equal to Earth's rotational period, one sidereal day, and so to ground observers it appears motionless, in a fixed position in the sky. The concept of a geostationary orbit was popularised by the science fiction writer Arthur C. Clarke in the 1940s as a way to revolutionise telecommunications, and the first satellite to be placed in this kind of orbit was launched in 1963. Communications satellites are often placed in a geostationary orbit so that Earth-based satellite antennas do not have to rotate to track them but can be pointed permanently at the position in the sky where the sate ...

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 ...

Solar Panels
A solar cell panel, solar electric panel, photo-voltaic (PV) module, PV panel or solar panel is an assembly of photovoltaic solar cells mounted in a (usually rectangular) frame, and a neatly organised collection of PV panels is called a photovoltaic system or solar array. Solar panels capture sunlight as a source of radiant energy, which is converted into electric energy in the form of direct current (DC) electricity. Arrays of a photovoltaic system can be used to generate solar electricity that supplies electrical equipment directly, or feeds power back into an alternate current (AC) grid via an inverter system. History In 1839, the ability of some materials to create an electrical charge from light exposure was first observed by the French physicist Edmond Becquerel. Though these initial solar panels were too inefficient for even simple electric devices, they were used as an instrument to measure light. The observation by Becquerel was not replicated again until 1873 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arianespace
Arianespace SA is a French company founded in 1980 as the world's first commercial launch service provider. It undertakes the operation and marketing of the Ariane programme. The company offers a number of different launch vehicles: the heavy-lift Ariane 5 for dual launches to geostationary transfer orbit, the Soyuz-2 as a medium-lift alternative, and the solid-fueled Vega for lighter payloads. , Arianespace had launched more than 850 satellites in 287 launches over 41 years. The first commercial flight managed by the new entity was Spacenet F1 launched on 23 May 1984. Arianespace uses the Guiana Space Centre in French Guiana as its main launch site. Through shareholding in Starsem, it can also offer commercial Soyuz launches from the Baikonur spaceport in Kazakhstan. It has its headquarters in Évry-Courcouronnes, Essonne, France. History The formation of Arianespace SA is closely associated with the desire of several European nations to pursue joint collaboration in ...
