ViaSat-2
ViaSat-2 is a commercial communications satellite launched June 1, 2017 and went live late February 2018. It was advertised to be the world's highest capacity communications satellite with a throughput of 300 Gbit/s, succeeding HughesNet EchoStar XIX launched in December 2016. It is the second Ka-band satellite launched by ViaSat after ViaSat-1. The satellite provides internet service through ViaSat (Exede prior to rebranding) to North America, parts of South America, including Mexico and the Caribbean, and to air and maritime routes across the Atlantic Ocean to Europe. History In May 2013, ViaSat gave the construction contract of the satellite to Boeing. On May 1, 2014 ViaSat sold capacity on the satellite to Xplornet Communications. In January 2015, ViaSat gave the launch contract to SpaceX in an uncontested auction. After SpaceX CRS-7 exploded after launch in June 2015, concerns arose that the investigation may affect the mission's launch window. On February 9, 2016 Arianesp ...

Ariane 5
Ariane 5 is a European heavy-lift space launch vehicle developed and operated by Arianespace for the European Space Agency (ESA). It is launched from the Centre Spatial Guyanais (CSG) in French Guiana. It has been used to deliver payloads into geostationary transfer orbit (GTO) or low Earth orbit (LEO). The launch vehicle had a streak of 82 consecutive successful launches between 9 April 2003 and 12 December 2017. Since 2014, Ariane 6, a direct successor system, is in development. The system was designed as an expendable launch system by the ''Centre national d'études spatiales'' (CNES), the French government's space agency, in cooperation with various European partners. Despite not being a direct derivative of its predecessor launch vehicle program, it is classified as part of the Ariane rocket family. ArianeGroup is the prime contractor for the manufacturing of the vehicles, leading a multi-country consortium of other European contractors. Ariane 5 was originally intende ...

2017 In Spaceflight
Notable spaceflight activities in 2017 included the maiden flight of India's Geosynchronous Satellite Launch Vehicle Mark III (also called LVM3) on 5 June and the first suborbital test of Rocket Lab's Electron rocket, inaugurating the Mahia spaceport in New Zealand. The rocket is named for its innovative Rutherford engine which feeds propellants via battery-powered electric motors instead of the usual gas generator and turbopumps. Overview China launched its new missile-derived Kaituozhe-2 variant on 2 March. The Japanese SS-520, a suborbital sounding rocket modified for orbital flight, failed to reach orbit in January. If successful, it would have become the smallest and lightest vehicle to ever put an object in orbit. The venerable Russian Soyuz-U workhorse was retired after its 786th mission on 22 February. On 30 March, the SES-10 mission was launched with a previously flown Falcon 9 first stage, achieving a key milestone in the SpaceX reusable launch system developm ...

2017 Social Unrest In French Guiana
The 2017 social unrest in French Guiana was a series of protests and strikes led by the "Collective of 500 Brothers" to highlight the issues of insecurity and infrastructure in French Guiana, France. It began on March 20, 2017 in Kourou, and spread all over French Guiana within a few days. Several international rocket and satellite launches were postponed, and March 28 saw the largest demonstration ever held in French Guiana. The protesters asked for more resources, and demanded an investment in infrastructure from the mainland government of €1 billion. The mainland government turned down and offered a government pledge of €1 million in infrastructure. Labor union leaders and three local politicians occupied the Guiana Space Centre on April 4–5, 2017. Supermarkets no longer sold fresh products due to road blocks in April 2017. The strikes became an issue in the 2017 French presidential election. Context French Guiana is fraught with tensions between different communities (in ...

Satellites Using The BSS-702 Bus
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 propulsion, ...

Satellite Internet Access
Satellite Internet access is Internet access provided through communication satellites. Modern consumer grade satellite Internet service is typically provided to individual users through geostationary satellites that can offer relatively high data speeds, with newer satellites using to achieve downstream data speeds up to 506 Mbit/s. In addition, new satellite internet constellations are being developed in low-earth orbit to enable low-latency internet access from space. History Following the launch of the first satellite, Sputnik 1, by the Soviet Union in October 1957, the US successfully launched the Explorer 1 satellite in 1958. The first commercial communications satellite was Telstar 1, built by Bell Labs and launched in July 1962. The idea of a geosynchronous satellite—one that could orbit the Earth above the equator and remain fixed by following the Earth's rotation—was first proposed by Herman Potočnik in 1928 and popularised by the science fiction author Art ...

Communications Satellites In Geostationary Orbit
Communication (from la, communicare, meaning "to share" or "to be in relation with") is usually defined as the transmission of information. The term may also refer to the message communicated through such transmissions or the field of inquiry studying them. There are many disagreements about its precise definition. John Peters argues that the difficulty of defining communication emerges from the fact that communication is both a universal phenomenon and a specific discipline of institutional academic study. One definitional strategy involves limiting what can be included in the category of communication (for example, requiring a "conscious intent" to persuade). By this logic, one possible definition of communication is the act of developing meaning among entities or groups through the use of sufficiently mutually understood signs, symbols, and semiotic conventions. An important distinction is between verbal communication, which happens through the use of a language, and non ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spacecraft Launched In 2017
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] |
Geostationary Orbit
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 sat ...
