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, consisting of three solid rocket stages, the P80FW, Zefiro 23, and Zefiro 9, topped by a liquid-fueled AVUM upper stage.
Italy led the Vega program, contributing 65% of its funding, with support from France, Spain, Belgium, the Netherlands, Switzerland, Sweden, and others. Vega was succeeded by the more powerful Vega C, which entered service in 2022. The original Vega made its final flight on 5September 2024.
Development Background During the mid-1990s, French firms Aérospatiale and SEP, along with Italian firm Bombrini-Parodi-Delfino (BPD), commenced discussions on the development of a proposed Ariane Complementary Launcher (ACL). Around the same time, Italy began to champion the concept of a new solid-propellant satellite launcher. This proposed launcher, dubbed Vega, was promoted as functioning to expand the range of European launch capabilities; Vega would be capable of launching a payload into a polar orbit. From the onset, the first of three stages would be based on the solid booster of the existing Ariane 5 expendable launch system while the second and third stages would make use of the in-development Zefiro rocket motor.Moxon, Julian; "ESA plan emphasises launchers" Flight International 8 April 1998
However, it was recognised to be a costly project and thus difficult for Italy alone to finance; accordingly, international partners were sought early on in order to proceed with development."Launcher proposals" Flight International 18 December 1996 In April 1998, it was publicly stated that the Vega programme was dependent upon the securing of roughly ECU70 million of industrial investment, as well as the availability of around ECU350 million of funding that had been requested from interested member states of the European Space Agency (ESA), led by France and Italy."Italy leads ESA interest in Vega K development" Flight International 29 April 1998 During June 1998, it was announced that ministers from European Space Agency (ESA) member states had agreed to proceed with the first phase of the development programme for Vega; the participating members were France, Belgium, the Netherlands, Spain and Italy – the latter had assumed 55% of the burden for financing the programme."ESA to develop small satellite launcher" Flight International 1 July 1998Furniss, Tim; "A late entry" Flight International 15 July 1998
By September 1998, it was projected that, if fully funded, Vega would perform its first launch during 2002.Furniss, Tim; "New European launcher awaits full funding" Flight International 8 September 1998 However, by early 1998, France was publicly showing displeasure in the programme, leading to disputes in its funding."Second test for Vega's Zefiro" Flight International 7 July 1999Furniss, Tim; "Finding a Role" Flight International 28 July 1999 A new, higher-performance version of the Vega was proposed, but this failed to sufficiently satisfy France. In September 1999, France decided to withdraw from the Vega programme entirely, leading to fears for the future of the launcher."ESA ponders Vega's future after France withdraws" Flight International 15 September 1999 In November 1999, European Space Agency (ESA) formally dropped Vega as an endorsed programme, a decision which was largely attributed to France's withdrawal; Italy declared that it would proceed regardless, and threatened to re-direct its allocated contributions for the further development of the Ariane 5 to meet the shortfall.Moxon, Julian and Andy Nativi; "French withdrawal prompts ESA to drop Vega project" Flight International 3 November 1999"ESA budgets for Ariane 5 updates" Flight International 1 February 2000
Around 2000, an alternative use for the Vega was explored as a medium-class booster rocket to be used in conjunction with an improved, up-rated model of the Ariane 5 heavy launcher.Furniss, Tim; "Arianespace adds Eurokot to satellite launcher range" Flight International 6 June 2000 In October 2000, it was announced that France and Italy had settled their year-long dispute over the Vega programme; France and Italy agreed to provide 35% and 52%, respectively, of the financing towards the all-composite P80 booster for the Ariane 5 — work which would be included in the Vega programme.Moxon, Julian and Giorgio di Barnado; "Vega agreement paves way for P80 booster for Ariane 5" Flight International 31 October 2000 In March 2001, FiatAvio and the Italian Space Agency (ASI) formed a new company, European Launch Vehicle (ELV), to assume responsibility for the majority of development work on the Vega programme.Nativi, Andy; "Italians form launcher company" Flight International 6 March 2001 By 2003, there was concerns that European Space Agency (ESA)'s recent adoption of the Russian Soyuz launcher would directly compete with the in-development Vega; demands for such launchers had declined with a downturn in the mobile telecommunications satellite market and doubts over the European Galileo satellite navigation system.Furniss, Tim; "Face the facts with Jean-Yves Le Gall" Flight International 15 June 2003
Programme launch In March 2003, contracts for development of the Vega launcher were signed by European Space Agency (ESA) and Centre national d'études spatiales (CNES), the French space agency; Italy provided 65% of funding while six additional nations contributed the remainder.Furniss, Tim; "Europe starts Vega development" Flight International 4 March 2003 In May 2004, it was reported that a contract was signed between commercial operator Arianespace and prime contractor ELV to perform vehicle integration at Kourou, French Guiana."Vega nears maiden flight" Flight International 25 May 2004 In November 2004, construction commenced upon a new dedicated launch pad for the Vega launcher at Kourou, this included a bunker and a self-propelled structure to assist assembly of the stages; this site was built over the original launch pad for the retired Ariane 1 launcher."Vega launch pad taking shape" Flight International 23 November 2004Coppinger, Rob; "Bigger Stage" Flight International 8 November 2005 In September 2005, the successful completion of key tests on the Vega's solid rocket motor igniters, a key milestone, was reported.Bentley, Ross; "Key tests for Vega igniters" Flight International 21 September 2005
In November 2005, European Space Agency (ESA) declared its desire for the development and deployment of an electric propulsion-powered module to work in conjunction with the Vega launcher; this envisioned module would transfer payloads between low Earth orbit (LEO) and a geostationary orbit (GEO)."ESA wants electronic module for Vega vehicle" Flight International 22 November 2005 During November 2005, it was reported that both Israel and India had shown formal interest in the Vega programme."Israel and India show interest in ESA's Vega" Flight International 29 November 2005 In December 2005, the Vega launcher, along with the Ariane and Soyuz launchers, were endorsed as the recognised "first choice" platforms for ESA payloads.Coppinger, Rob; "ESA boosts science, delays Kliper" Flight International 13 December 2005 On 19 December 2005, the first test firing of the Vega's third stage was completed successfully at Salto di Quirra, Sardinia."Vega fires up on third-stage test" Flight International 3 January 2006 For several years, further tests would be conducted at the Sardinia site."Vega launcher rocket engine tests progress with Sardinian trial firing" Flight International 4 July 2006Coppinger, Rob; "Rocket propulsion sees triple success" Flight International 3 April 2008 Progress on Vega was delayed by the failure of one such test of the third stage on 28 March 2007."Vega third stage engine fails" Flight International 30 March 2007Coppinger, Rob; "Italian Space Agency plans its relaunch" Flight International 31 October 2008
