Sociedad Anónima
The abbreviation S.A. or SA designates a type of limited company in certain countries, most of which have a Romance languages, Romance language as their official language and operate a derivative of the 1804, Napoleonic, civil law (legal system), civil law. Originally, shareholders could be anonymous and collect dividends by surrendering coupon (finance), coupons attached to their stock certificate, share certificates. Dividends were paid to whomever held the certificate. Since share certificates could be transferred privately, corporate management would not necessarily know who owned its shares – nor did anyone but the holders. As with bearer bonds, anonymous unregistered share ownership and dividend collection enabled money laundering, tax evasion, and concealed business transactions in general, so governments passed laws to audit the practice. Nowadays, shareholders of S.A.s are not anonymous, though shares can still be held by a holding company to obscure the benefici ...

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.

Communications Satellite Operators
Communication is commonly defined as the transmission of information. Its precise definition is disputed and there are disagreements about whether Intention, unintentional or failed transmissions are included and whether communication not only transmits semantics, 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 code, coding system to express information in the form of a message. The message is sent through a Communication channel, 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 communication, verbal and non-verbal communication. Verba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vega (rocket)
Vega (, , ) was a European expendable small-lift launch vehicle developed by Avio and operated by Arianespace for the European Space Agency (ESA) and the Italian Space Agency (ASI). Designed to carry payloads between into low Earth and polar orbits, Vega served primarily scientific and Earth observation missions. Development of Vega began in 1998, with its maiden flight launched from the Guiana Space Centre on 13February 2012. Over the next decade, it became the eighth most launched small-lift launch vehicle history, though it struggled to compete in the commercial launch market. After initial success, two in-flight failures and rising competition from SpaceX's rideshare programs, which offered lower prices, relegated Vega to primarily serving European government agencies willing to pay more to support independent space access. The rocket took its name from Vega, the brightest star in the constellation Lyra. It featured a single-body design without strap-on boosters, con ...
