Ariane 5 is a retired European heavy-lift space launch vehicle developed and operated by Arianespace for the European Space Agency (ESA). It was launched from the Centre Spatial Guyanais (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, is in development.
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.
The Guiana Space Centre, also called Europe's Spaceport, is a European spaceport to the northwest of Kourou in French Guiana, a region of France in South America. Kourou is located approximately 310 mi (500 km) north of the equator at a latitude of 5°. In operation since 1968, it is a suitable location for a spaceport because of its equatorial location and open sea to the east.
Vega is an expendable launch system in use by Arianespace jointly developed by the Italian Space Agency (ASI) and the European Space Agency (ESA). Development began in 1998 and the first launch took place from the Centre Spatial Guyanais on 13 February 2012.
Launch Services Alliance is a "back-up" launch service provider. It is a joint venture between the multinational aerospace company Arianespace and Japanese conglomerate Mitsubishi Heavy Industries; initially, the American aerospace firm Boeing Launch Services was involved as well.
HYLAS is a British satellite in geostationary orbit. HYLAS, which is an acronym for Highly Adaptable Satellite, is a communications satellite and was launched by the European Ariane 5 launch vehicle from the Guyana Space Centre at Kourou in French Guiana. It is located at the orbital location of 33.5 degrees west and will provide new and innovative services including High Definition Television (HDTV) and interactive satellite delivered broadband services. The satellite will help address the issue of poor broadband coverage in many parts of Europe which have less developed ground infrastructure.
This comparison of orbital launch systems lists the attributes of all individual rocket configurations designed to reach orbit. A first list contains rockets that are operational or in development as of 2023; a second list includes all upcoming rockets and a third list includes all retired rockets For the simple list of all conventional launcher families, see: Comparison of orbital launchers families. For the list of predominantly solid-fueled orbital launch systems, see: Comparison of solid-fueled orbital launch systems.
This article documents notable spaceflight events during the year 2018. For the first time since 1990, more than 100 orbital launches were performed globally.
Ariane 6 is a European expendable launch system under development since the early 2010s by ArianeGroup on behalf of the European Space Agency (ESA). It replaces the Ariane 5, as part of the Ariane launch vehicle family. The stated motivation for Ariane 6 was to halve the cost compared to Ariane 5, and increase the capacity for the number of launches per year.
Space launch market competition is the manifestation of market forces in the launch service provider business. In particular it is the trend of competitive dynamics among payload transport capabilities at diverse prices having a greater influence on launch purchasing than the traditional political considerations of country of manufacture or the national entity using, regulating or licensing the launch service.
ArianeGroup is an aerospace company based in France. A joint venture between Airbus and Safran, the company was founded in 2015 and is headquartered in Issy-les-Moulineaux. It consists of three core groups: aerospace, defence and security. ArianeGroup is developing its next-generation two-stage Ariane 6 launch vehicle, intended to succeed the Ariane 5 rocket, which has had more than 110 launches. The new vehicle will be offered in two variants that will be capable of carrying between 10,350 and 21,650 kilograms. The first launch of Ariane 6 is expected to occur in 2024.
The JSAT constellation is a communication and broadcasting satellite constellation formerly operated by JSAT Corporation and currently by SKY Perfect JSAT Group. It has become the most important commercial constellation in Japan, and fifth in the world. It has practically amalgamated all private satellite operators in Japan, with only B-SAT left as a local competitor.
ViaSat-3 is a planned global constellation of three geostationary Ka-band communications satellites, the first of which was launched in 2023 by Viasat, Inc. The satellites are intended to provide broadband connectivity with speeds of 100-plus megabits per second to homes, business and enterprise internet users, commercial, government and business aircraft, as well as government and defense markets, maritime and oceanic enterprises in the Americas, Europe, the Middle East, Africa and Asia-Pacific.
