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, exceeding that of HughesNet EchoStar XIX, which 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.

Ariane 5
Ariane 5 is a retired European heavy-lift space launch vehicle operated by Arianespace for the European Space Agency (ESA). It was launched from the Guiana Space Centre (CSG) in French Guiana. It was used to deliver payloads into geostationary transfer orbit (GTO), low Earth orbit (LEO) or further into space. 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, first launched in 2024. The system was designed as an expendable launch vehicle 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 was classified as part of the Ariane rocket family. Aérospatiale, and later ArianeGroup, was the prime contractor for the manufacturing of the vehicles, leading a multi-country consortium of other European con ...

2017 In Spaceflight
Notable spaceflight activities in 2017 included the maiden flight, maiden orbital 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 (rocket engine), Rutherford engine which feeds propellants via Electric pump-fed engine, 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 S-Series (rocket family)#SS-520-4, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ( ...

Satellites Using The BSS-702 Bus
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. Becau ...

Satellite Internet Access
Satellite Internet access is Internet access provided through communication satellites; if it can sustain high-speed Internet, high speeds, it is termed satellite broadband. 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 the to achieve downstream data speeds up to 506 Data-rate units#Megabit per second, Mbit/s. In addition, new satellite internet constellations are being developed in Low Earth orbit, low-earth orbit to enable Network delay, 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, Telstar 1, built by Bell Labs and launched in July 1962. The idea of a geosynchronous satellite—one that could orbit the Earth ...

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 ...

Spacecraft Launched In 2017
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] |
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 orbit, circular geosynchronous orbit in altitude above Earth's equator, in radius from Earth's center, and following the retrograde and prograde motion, direction of Earth's rotation. An object in such an orbit has an orbital period equal to Earth's rotational period, one sidereal time, 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 dish, satellite antennas do not have to rotate to track t ...
