Artemis (satellite)
Artemis was a geostationary earth orbit satellite (GEOS) for telecommunications, built by Alenia Spazio for European Space Agency, ESA. The Artemis satellite operated at the 21.5E orbital position until 2016, when it was moved to 123E to cover the L-Band spectrum rights for Indonesia's Ministry of Defense. In November 2017, Artemis was retired and replaced to a graveyard orbit. The mission was planned for many years, with launch initially intended for 1995 and slipping; it was intended for launch on Ariane 5 but at one point there were suggestions that a Japanese H-II, H-II rocket might be used. Launched by an Ariane 5 rocket on 12 July 2001, it originally reached an orbit much lower than planned (590 km x 17487 km) due to a malfunction in the launch vehicle's upper stage. It was remotely reconfigured to reach its intended station by means of a novel procedure. First, over the course of about a week, most of its chemical fuel was used to put it in a 31,000 km cir ...

Spacecraft Launched In 2001
A spacecraft is a vehicle that is designed to fly and operate in outer space. 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 research are space pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellite Launch Anomalies
A satellite or an artificial satellite is an object, typically a spacecraft, placed into orbit around a celestial body. They have a variety of uses, including communication relay, weather forecasting, navigation ( GPS), broadcasting, scientific research, and Earth observation. Additional military uses are reconnaissance, early warning, signals intelligence and, potentially, weapon delivery. Other satellites include the final rocket stages that place satellites in orbit and formerly useful satellites that later become defunct. 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 are small CubeSats. Similar satellites can work together as groups, forming constellations. Bec ...

Communications Satellites In Geostationary Orbit
Communication is commonly defined as the transmission of information. Its precise definition is disputed and there are disagreements about whether unintentional or failed transmissions are included and whether communication not only transmits meaning but also creates it. Models of communication are simplified overviews of its main components and their interactions. Many models include the idea that a source uses a coding system to express information in the form of a message. The message is sent through a channel to a receiver who has to decode it to understand it. The main field of inquiry investigating communication is called communication studies. A common way to classify communication is by whether information is exchanged between humans, members of other species, or non-living entities such as computers. For human communication, a central contrast is between verbal and non-verbal communication. Verbal communication involves the exchange of messages in linguistic form ...

London Court Of International Arbitration
The London Court of International Arbitration (LCIA) is the oldest arbitral body in the world dealing with international disputes. It was founded as a British private company limited by guarantee with a head office in London. It offers dispute resolution through arbitration and mediation. History The City of London Chamber of Arbitration was established in 1892, not long after the Arbitration Act of 1889 became law. It consisted of members of the City of London Corporation and the London Chamber of Commerce & Industry, and had its seat at the Guildhall in London. The '' Law Quarterly Review'' said of it at the time: "it is to be expeditious where the law is slow. Hitesh Singh from Navi Mumbai being one of the famous Directors of the institution". The name was changed to "London Court of Arbitration" in 1903, and to the present name in 1981.

European Data Relay Satellite
The European Data Relay System (EDRS) system is a European constellation of GEO satellites that relay information and data between satellites, spacecraft, UAVs, and ground stations. The first components (a payload and dedicated GEO satellite) were launched in 2016 and 2019. Purpose and context The designers intend the system to provide almost full-time communication, even with satellites in low Earth orbit that often have reduced visibility from ground stations. It makes on-demand data available to, for example, rescue workers who want near-real-time satellite data of a crisis region. There are a number of key services that will benefit from this system's infrastructure: * Earth Observation applications in support of time-critical and/or data-intensive services; e.g., change detection, environmental monitoring. * Government and security services that need images from key European space systems such as Global Monitoring for Environment and Security. * Emergency response and cris ...

Jules Verne ATV
The ''Jules Verne'' ATV, or Automated Transfer Vehicle 1 (ATV-1), was a robotic cargo spacecraft launched by the European Space Agency (ESA). The ATV was named after the 19th-century French science-fiction author Jules Verne. It was launched on 9 March 2008 on a mission to supply the International Space Station (ISS) with propellant, water, air, and dry cargo. ''Jules Verne'' was the first of five Automated Transfer Vehicle spacecraft to be launched. Because it was the first ATV to be launched, ''Jules Verne'' underwent three weeks of orbital testing before beginning its final rendezvous with the ISS. The spacecraft docked to the ISS on 3 April 2008 to deliver its cargo. On 25 April 2008, ''Jules Verne'' used its thrusters to reboost the station into a higher orbit. After spending just over five months docked at the station, ''Jules Verne'' undocked on 5 September 2008 and made a destructive re-entry over the Pacific Ocean on 29 September. Development ...
