History


Foundation

After World War II, many European scientists left Western Europe in order to work with the United States. Although the 1950s boom made it possible for Western European countries to invest in research and specifically in space-related activities, Western European scientists realised solely national projects would not be able to compete with the two main superpowers. In 1958, only months after the Sputnik crisis, Sputnik shock, Edoardo Amaldi (Italy) and Pierre Victor Auger, Pierre Auger (France), two prominent members of the Western European scientific community, met to discuss the foundation of a common Western European space agency. The meeting was attended by scientific representatives from eight countries, including Harrie Massey (United Kingdom). The Western European nations decided to have two agencies: one concerned with developing a launch system, European Launcher Development Organization, ELDO (European Launch Development Organization), and the other the precursor of the European Space Agency, ESRO (European Space Research Organisation). The latter was established on 20 March 1964 by an agreement signed on 14 June 1962. From 1968 to 1972, ESRO launched seven research satellites. ESA in its current form was founded with the ESA Convention in 1975, when ESRO was merged with ELDO. ESA had ten founding member states: Belgium, Denmark, France, West Germany, Italy, the Netherlands, Spain, Sweden, Switzerland, and the United Kingdom. These signed the ESA Convention in 1975 and deposited the instruments of ratification by 1980, when the convention came into force. During this interval the agency functioned in a de facto fashion. ESA launched its first major scientific mission in 1975, Cos-B, a space probe monitoring Gamma-ray astronomy, gamma-ray emissions in the universe, which was first worked on by ESRO.


Later activities

ESA collaborated with
NASA The National Aeronautics and Space Administration (NASA; ) is an independent agencies of the United States government, independent agency of the Federal government of the United States, U.S. federal government responsible for the civilian Li ...
on the International Ultraviolet Explorer (IUE), the world's first high-orbit telescope, which was launched in 1978 and operated successfully for 18 years. A number of successful Earth-orbit projects followed, and in 1986 ESA began Giotto mission, Giotto, its first deep-space mission, to study the comets Comet Halley, Halley and 26P/Grigg–Skjellerup, Grigg–Skjellerup. Hipparcos, a star-mapping mission, was launched in 1989 and in the 1990s Solar and Heliospheric Observatory, SOHO, ''Ulysses probe, Ulysses'' and the Hubble Space Telescope were all jointly carried out with NASA. Later scientific missions in cooperation with NASA include the ''Cassini–Huygens'' space probe, to which ESA contributed by building the Titan (moon), Titan landing module ''Huygens (spacecraft), Huygens''. As the successor of European Launcher Development Organisation, ELDO, ESA has also constructed rockets for scientific and commercial payloads. Ariane 1, launched in 1979, carried mostly commercial payloads into orbit from 1984 onward. The next two versions of the Ariane rocket were intermediate stages in the development of a more advanced launch system, the Ariane 4, which operated between 1988 and 2003 and established ESA as the world leader in commercial space launches in the 1990s. Although the succeeding Ariane 5 experienced a failure on its first flight, it has since firmly established itself within the heavily competitive commercial space launch market with 82 successful launches until 2018. The successor launch vehicle of Ariane 5, the Ariane 6, is under development and is envisioned to enter service in the 2020s. The beginning of the new millennium saw ESA become, along with agencies like NASA, JAXA, ISRO, the Canadian Space Agency, CSA and Roscosmos, one of the major participants in scientific Space science, space research. Although ESA had relied on co-operation with NASA in previous decades, especially the 1990s, changed circumstances (such as tough legal restrictions on information sharing by the Military of the United States, United States military) led to decisions to rely more on itself and on co-operation with Russia. A 2011 press issue thus stated: Notable ESA programmes include SMART-1, a probe testing cutting-edge space propulsion technology, the ''Mars Express'' and ''Venus Express'' missions, as well as the development of the Ariane 5 rocket and its role in the International Space Station, ISS partnership. ESA maintains its scientific and research projects mainly for astronomy-space missions such as Corot (space mission), Corot, launched on 27 December 2006, a milestone in the search for exoplanets. On 21 January 2019, ArianeGroup and Arianespace announced a one-year contract with ESA to study and prepare for a mission to mine the Moon for lunar regolith.


Mission

The treaty establishing the European Space Agency reads:Article II, Purpose, Convention of establishment of a European Space Agency, SP-1271(E) from 2003 . ESA is responsible for setting a unified space and related industrial policy, recommending space objectives to the member states, and integrating national programs like satellite development, into the European program as much as possible. Jean-Jacques Dordain – ESA's Director General (2003–2015) – outlined the European Space Agency's mission in a 2003 interview:


Activities and programmes

ESA describes its work in two overlapping ways: * For the general public, the various fields of work are described as Activities. * Budgets are organized as Programmes ''(British spelling retained because it is a term of official documents).'' These are either Mandatory or Optional.

Member states, funding and budget


Membership and contribution to ESA

By 2015, ESA was an intergovernmental organisation of 22 member states. Member states participate to varying degrees in the mandatory (25% of total expenditures in 2008) and optional space programmes (75% of total expenditures in 2008). The 2008 budget amounted to €3.0 billion whilst the 2009 budget amounted to €3.6 billion. The total budget amounted to about €3.7 billion in 2010, €3.99 billion in 2011, €4.02 billion in 2012, €4.28 billion in 2013, €4.10 billion in 2014 and €4.33 billion in 2015. English is the main language within ESA. Additionally, official documents are also provided in German and documents regarding the Spacelab are also provided in Italian. If found appropriate, the agency may conduct its correspondence in any language of a member state. The following table lists all the member states and adjunct members, their ESA convention ratification dates, and their contributions in 2020:


Non-full member states


Slovenia

Since 2016, Slovenia has been an associated member of the ESA.


Latvia

Latvia became the second current associated member on 30 June 2020, when the Association Agreement was signed by ESA Director Jan Wörner and the Ministry of Education and Science (Latvia), Minister of Education and Science of Latvia, Ilga Šuplinska in Riga. The Saeima ratified it on July 27. Previously associated members were Austria, Norway and Finland, all of which later joined ESA as full members.


Canada

Since 1 January 1979, Canada has had the special status of a Cooperating State within ESA. By virtue of this accord, the Canadian Space Agency takes part in ESA's deliberative bodies and decision-making and also in ESA's programmes and activities. Canadian firms can bid for and receive contracts to work on programmes. The accord has a provision ensuring a fair industrial return to Canada. The most recent Cooperation Agreement was signed on 15 December 2010 with a term extending to 2020. For 2014, Canada's annual assessed contribution to the ESA general budget was €6,059,449 (Canadian dollar, CAD$8,559,050). For 2017, Canada has increased its annual contribution to €21,600,000 (Canadian dollar, CAD$30,000,000).


Budget appropriation and allocation

ESA is funded from annual contributions by national governments as well as from an annual contribution by the European Union (EU). The budget of ESA was €5.250 billion in 2016. Every 3–4 years, ESA member states agree on a budget plan for several years at an ESA member states conference. This plan can be amended in future years, however provides the major guideline for ESA for several years. The 2016 budget allocations for major areas of ESA activity are shown in the chart on the right. Countries typically have their own space programmes that differ in how they operate organisationally and financially with ESA. For example, the French space agency CNES has a total budget of €2015 million, of which €755 million is paid as direct financial contribution to ESA. Several space-related projects are joint projects between national space agencies and ESA (e.g. COROT). Also, ESA is not the only European governmental space organisation (for example European Union Satellite Centre).


Enlargement

After the decision of the ESA Council of 21/22 March 2001, the procedure for accession of the European states was detailed as described the document titled "The Plan for European Co-operating States (PECS)". Nations that want to become a full member of ESA do so in 3 stages. First a Cooperation Agreement is signed between the country and ESA. In this stage, the country has very limited financial responsibilities. If a country wants to co-operate more fully with ESA, it signs a European Cooperating State (ECS) Agreement. The ECS Agreement makes companies based in the country eligible for participation in ESA procurements. The country can also participate in all ESA programmes, except for the Basic Technology Research Programme. While the financial contribution of the country concerned increases, it is still much lower than that of a full member state. The agreement is normally followed by a Plan For European Cooperating State (or PECS Charter). This is a 5-year programme of basic research and development activities aimed at improving the nation's space industry capacity. At the end of the 5-year period, the country can either begin negotiations to become a full member state or an associated state or sign a new PECS Charter. Many countries, most of which joined the EU in both 2004 and 2007, have started to co-operate with ESA on various levels: During the Ministerial Meeting in December 2014, ESA ministers approved a resolution calling for discussions to begin with Israel, Australia and South Africa on future association agreements. The ministers noted that "concrete cooperation is at an advanced stage" with these nations and that "prospects for mutual benefits are existing". A separate space exploration strategy resolution calls for further co-operation with the United States, Russia and China on "LEO exploration, including a continuation of ISS cooperation and the development of a robust plan for the coordinated use of space transportation vehicles and systems for exploration purposes, participation in robotic missions for the exploration of the Moon, the robotic exploration of Mars, leading to a broad Mars Sample Return mission in which Europe should be involved as a full partner, and human missions beyond LEO in the longer term."


Relationship with the European Union

The political perspective of the European Union (EU) was to make ESA an Agency of the European Union, agency of the EU by 2014, although this date was not met. The EU member states provide most of ESA's funding, and they are all either full ESA members or observers.


Launch vehicle fleet

ESA has a fleet of different launch vehicles in service with which it competes in all sectors of the launch market. ESA's fleet consists of three major rocket designs: Ariane 5, Soyuz-2 (rocket), Soyuz-2 and Vega (launcher), Vega. Rocket launches are carried out by Arianespace, which has 23 shareholders representing the industry that manufactures the Ariane 5 as well as CNES, at ESA's Guiana Space Centre. Because many communication satellites have equatorial orbits, launches from French Guiana are able to take larger payloads into space than from spaceports at higher latitudes. In addition, equatorial launches give spacecraft an extra 'push' of nearly 500 m/s due to the higher rotational velocity of the Earth at the equator compared to near the Earth's poles where rotational velocity approaches zero.


Ariane 5

The Ariane 5 rocket is ESA's primary launcher. It has been in service since 1997 and replaced Ariane 4. Two different Ariane 5#Variants, variants are currently in use. The heaviest and most used version, the , delivers two communications satellites of up to 10 tonnes into Geostationary transfer orbit, GTO. It failed during its first test flight in 2002, but has since made 82 consecutive successful Ariane 5#Ariane 5 flights, flights until a partial failure in January 2018. The other version, , was used to launch the Automated Transfer Vehicle (ATV) to the (ISS) and will be used to launch four Galileo (satellite navigation), Galileo navigational satellites at a time. In November 2012, ESA agreed to build an upgraded variant called Ariane 5#Ariane 5 ME, (Mid-life Evolution) which would increase payload capacity to 11.5 tonnes to GTO and feature a restartable second stage to allow more complex missions. Ariane 5 ME was scheduled to fly in 2018, but the whole project was scrapped in favor of Ariane 6, planned to replace Ariane 5 in the 2020s. ESA's Ariane 1, Ariane 2, 2, Ariane 3, 3 and Ariane 4, 4 launchers (the last of which was ESA's long-time workhorse) have been retired.


Soyuz

Soyuz-2 (rocket), Soyuz-2 (also called the Soyuz-ST or Soyuz-STK) is a Russian medium payload launcher (ca. 3 metric tons to Geostationary transfer orbit, GTO) which was brought into ESA service in October 2011. ESA entered into a €340 million joint venture with the Russian Federal Space Agency over the use of the Soyuz launcher. Under the agreement, the Russian agency manufactures Soyuz rocket parts for ESA, which are then shipped to French Guiana for assembly. ESA benefits because it gains a medium payload launcher, complementing its fleet while saving on development costs. In addition, the Soyuz rocket—which has been the Russian's space launch workhorse for more than 50 years—is proven technology with a very good safety record. Russia benefits in that it gets access to the Kourou launch site. Due to its proximity to the equator, launching from Kourou rather than Baikonur Cosmodrome, Baikonur nearly doubles Soyuz's payload to Geostationary transfer orbit, GTO (3.0 tonnes vs. 1.7 tonnes). Soyuz first launched from Kourou on 21 October 2011, and successfully placed two Galileo (satellite navigation), Galileo satellites into orbit 23,222 kilometres above Earth.


Vega

Vega is ESA's carrier for small satellites. Developed by seven ESA members led by Italian Space Agency, Italy, it is capable of carrying a payload with a mass of between 300 and 1500 kg to an altitude of 700 km, for low polar orbit. Its maiden launch from Guiana Space Centre, Kourou was on 13 February 2012. Vega began full commercial exploitation in December 2015. The rocket has three solid propulsion stages and a liquid rocket, liquid propulsion upper stage (the AVUM) for accurate orbital insertion and the ability to place multiple Payload (air and space craft), payloads into different orbits. A larger version of the Vega launcher, Vega (rocket)#Vega-C and Vega-E, Vega-C is in development and the first flight is expected in June 2021. The new evolution of the rocket incorporates a larger first stage booster, the P120 (rocket stage), P120C replacing the P80 (rocket stage), P80, an upgraded Zefiro (rocket stage) second stage, and the AVUM+ upper stage. This new variant enables larger single payloads, dual payloads, return missions, and orbital transfer capabilities.


Ariane launch vehicle development funding

Historically, the Ariane family rockets have been funded primarily "with money contributed by ESA governments seeking to participate in the program rather than through competitive industry bids. This [has meant that] governments commit multiyear funding to the development with the expectation of a roughly 90% return on investment in the form of industrial workshare." ESA is proposing changes to this scheme by moving to competition (economics), competitive bids for the development of the Ariane 6.


Human space flight


History

At the time ESA was formed, its main goals did not encompass human space flight; rather it considered itself to be primarily a scientific research organisation for uncrewed space exploration in contrast to its American and Soviet counterparts. It is therefore not surprising that the first non-Soviet European in space was not an ESA astronaut on a European space craft; it was Czechoslovak Vladimír Remek who in 1978 became the first non-Soviet or American in space (the first man in space being Yuri Gagarin of the Soviet Union) – on a Soviet space programme, Soviet Soyuz spacecraft, followed by the Poles, Pole Mirosław Hermaszewski and East German Sigmund Jähn in the same year. This Soviet co-operation programme, known as Intercosmos, primarily involved the participation of Eastern bloc countries. In 1982, however, Jean-Loup Chrétien became the first Western Bloc, non-Communist Bloc astronaut on a flight to the Soviet Salyut 7 space station. Because Chrétien did not officially fly into space as an ESA astronaut, but rather as a member of the French CNES astronaut corps, the German Ulf Merbold is considered the first ESA astronaut to fly into space. He participated in the STS-9 Space Shuttle mission that included the first use of the European-built Spacelab in 1983. STS-9 marked the beginning of an extensive ESA/NASA joint partnership that included dozens of space flights of ESA astronauts in the following years. Some of these missions with Spacelab were fully funded and organizationally and scientifically controlled by ESA (such as two missions by Germany and one by Japan) with European astronauts as full crew members rather than guests on board. Beside paying for Spacelab flights and seats on the shuttles, ESA continued its human space flight co-operation with the Soviet Union and later Russia, including numerous visits to Mir. During the latter half of the 1980s, European human space flights changed from being the exception to routine and therefore, in 1990, the European Astronaut Centre in Cologne, Germany was established. It selects and trains prospective astronauts and is responsible for the co-ordination with international partners, especially with regard to the . As of 2006, the ESA astronaut corps officially included twelve members, including nationals from most large European countries except the United Kingdom. In the summer of 2008, ESA started to recruit new astronauts so that final selection would be due in spring 2009. Almost 10,000 people registered as astronaut candidates before registration ended in June 2008. 8,413 fulfilled the initial application criteria. Of the applicants, 918 were chosen to take part in the first stage of psychological testing, which narrowed down the field to 192. After two-stage psychological tests and medical evaluation in early 2009, as well as formal interviews, six new members of the European Astronaut Corps were selected – five men and one woman.

Crew vehicles

In the 1980s, France pressed for an independent European crew launch vehicle. Around 1978, it was decided to pursue a reusable spacecraft model and starting in November 1987 a project to create a mini-shuttle by the name of Hermes (shuttle), Hermes was introduced. The craft was comparable to early proposals for the Space Shuttle and consisted of a small reusable spaceship that would carry 3 to 5 astronauts and 3 to 4 metric tons of payload for scientific experiments. With a total maximum weight of 21 metric tons it would have been launched on the Ariane 5 rocket, which was being developed at that time. It was planned solely for use in low Earth orbit space flights. The planning and pre-development phase concluded in 1991; the production phase was never fully implemented because at that time the political landscape had changed significantly. With the fall of the Soviet Union ESA looked forward to co-operation with Russia to build a next-generation space vehicle. Thus the Hermes programme was cancelled in 1995 after about 3 billion dollars had been spent. The Columbus Man-Tended Free Flyer, Columbus space station programme had a similar fate. In the 21st century, ESA started new programmes in order to create its own crew vehicles, most notable among its various projects and proposals is Hopper (spacecraft), Hopper, whose prototype by Airbus, EADS, called EADS Phoenix, Phoenix, has already been tested. While projects such as Hopper (spacecraft), Hopper are neither concrete nor to be realised within the next decade, other possibilities for human spaceflight in co-operation with the Russian Space Agency have emerged. Following talks with the Russian Space Agency in 2004 and June 2005, a co-operation between ESA and the Russian Space Agency was announced to jointly work on the Russian-designed Kliper, a reusable spacecraft that would be available for space travel beyond LEO (e.g. the moon or even Mars). It was speculated that Europe would finance part of it. A €50 million participation study for Kliper, which was expected to be approved in December 2005, was finally not approved by the ESA member states. The Russian state tender for the project was subsequently cancelled in 2006. In June 2006, ESA member states granted 15 million to the CSTS, Crew Space Transportation System (CSTS) study, a two-year study to design a spacecraft capable of going beyond Low-Earth orbit based on the current Soyuz spacecraft, Soyuz design. This project was pursued with Roskosmos instead of the cancelled Kliper proposal. A decision on the actual implementation and construction of the CSTS spacecraft was contemplated for 2008. In mid-2009 EADS Astrium was awarded a €21 million study into designing a crew vehicle based on the European ATV which is believed to now be the basis of the Advanced Crew Transportation System design. In November 2012, ESA decided to join NASA's Orion (spacecraft), Orion programme. The ATV would form the basis of a propulsion unit for NASA's new crewed spacecraft. ESA may also seek to work with NASA on Orion's launch system as well in order to secure a seat on the spacecraft for its own astronauts. In September 2014, ESA signed an agreement with Sierra Nevada Corporation for co-operation in Dream Chaser project. Further studies on the Dream Chaser for European Utilization or DC4EU project were funded, including the feasibility of launching a Europeanized Dream Chaser onboard Ariane 5.


Cooperation with other countries and organisations

ESA has signed co-operation agreements with the following states that currently neither plan to integrate as tightly with ESA institutions as Canada, nor envision future membership of ESA: Argentina, Brazil, China, India (for the Chandrayan mission), Russia and Turkey. Additionally, ESA has joint projects with the European Union,

of the United States and is participating in the together with the United States (NASA), Russia and Japan (JAXA).


European Union

ESA is not an agency or body of the European Union (EU), and has non-EU countries (Norway, Switzerland, and the United Kingdom) as members. There are however ties between the two, with various agreements in place and being worked on, to define the legal status of ESA with regard to the EU. There are common goals between ESA and the EU. ESA has an EU liaison office in Brussels. On certain projects, the EU and ESA co-operate, such as the upcoming Galileo (satellite navigation), Galileo satellite navigation system. Space policy has since December 2009 been an area for voting in the European Council. Under the European Space Policy, European Space Policy of 2007, the EU, ESA and its Member States committed themselves to increasing co-ordination of their activities and programmes and to organising their respective roles relating to space. The Lisbon Treaty of 2009 reinforces the case for space in Europe and strengthens the role of ESA as an R&D space agency. Article 189 of the Treaty gives the EU a mandate to elaborate a European space policy and take related measures, and provides that the EU should establish appropriate relations with ESA. Former Italian astronaut Umberto Guidoni, during his tenure as a Member of the European Parliament from 2004 to 2009, stressed the importance of the European Union as a driving force for space exploration, "since other players are coming up such as India and China it is becoming ever more important that Europeans can have an independent access to space. We have to invest more into space research and technology in order to have an industry capable of competing with other international players." The first EU-ESA International Conference on Human Space Exploration took place in Prague on 22 and 23 October 2009. A road map which would lead to a common vision and strategic planning in the area of space exploration was discussed. Ministers from all 29 EU and ESA members as well as members of parliament were in attendance.

In the 1980s and 1990s, the Spacelab programme was an ESA-NASA joint research programme that had ESA develop and manufacture orbital labs for the Space Shuttle for several flights on which ESA participate with astronauts in experiments. In robotic science mission and exploration missions, NASA has been ESA's main partner. ''Cassini–Huygens'' was a joint NASA-ESA mission, along with the Infrared Space Observatory, INTEGRAL, Solar and Heliospheric Observatory, SOHO, and others. Also, the Hubble Space Telescope is a joint project of NASA and ESA. Future ESA-NASA joint projects include the James Webb Space Telescope and the proposed Laser Interferometer Space Antenna. NASA has supported ESA's MarcoPolo-R mission which landed on asteroid Bennu in October 2020 and is scheduled to return a sample to Earth for further analysis in 2023. NASA and ESA will also likely join together for a Mars sample-return mission. In October 2020 the ESA entered into a memorandum of understanding (MOU) with NASA to work together on the Artemis program, which will provide an orbiting Lunar Gateway and also accomplish the first manned lunar landing in 50 years, whose team will include the first woman on the Moon. Astronaut selection announcements are expected within two years of the 2024 scheduled launch date.


Cooperation with other space agencies

Since China has started to invest more money into space activities, the Chinese Space Agency has sought international partnerships. ESA is, beside the Russian Space Agency, one of its most important partners. Two space agencies cooperated in the development of the Double Star Mission. In 2017, ESA sent two astronauts to China for two weeks sea survival training with Chinese astronauts in Yantai, Shandong. ESA entered into a major joint venture with Russia in the form of the CSTS, the preparation of

spaceport for launches of Soyuz-2 (rocket), Soyuz-2 rockets and other projects. With India, ESA agreed to send instruments into space aboard the ISRO's Chandrayaan-1 in 2008. ESA is also co-operating with Japan, the most notable current project in collaboration with JAXA is the ''BepiColombo'' mission to Mercury (planet), Mercury. Speaking to reporters at an air show near Moscow in August 2011, ESA head Jean-Jacques Dordain said ESA and Russia's Roskosmos space agency would "carry out the first flight to Mars together."


International Space Station

With regard to the (ISS) ESA is not represented by all of its member states: 10 of the 21 ESA member states currently participate in the project: Belgium, Denmark, France, Germany, Italy, Netherlands, Norway, Spain, Sweden and Switzerland. Austria, Finland and Ireland chose not to participate, because of lack of interest or concerns about the expense of the project. The United Kingdom withdrew from the International Space Station programme, preliminary agreement because of concerns about the expense of the project. Portugal, Luxembourg, Greece, the Czech Republic, Romania and Poland joined ESA after the agreement had been signed. ESA is taking part in the construction and operation of the International Space Station, ISS with contributions such as Columbus (ISS module), Columbus, a science laboratory module that was brought into orbit by NASA's STS-122 Space Shuttle mission and the Cupola (ISS module), Cupola observatory module that was completed in July 2005 by Alenia Aeronautica, Alenia Spazio for ESA. The current estimates for the ISS are approaching €100 billion in total (development, construction and 10 years of maintaining the station) of which ESA has committed to paying €8 billion. About 90% of the costs of ESA's ISS share will be contributed by Germany (41%), France (28%) and Italy (20%). German ESA astronaut Thomas Reiter was the first long-term ISS crew member. ESA has developed the Automated Transfer Vehicle for ISS resupply. Each ATV has a cargo capacity of . The first ATV, ''Jules Verne ATV, Jules Verne'', was launched on 9 March 2008 and on 3 April 2008 successfully docked with the ISS. This manoeuvre, considered a major technical feat, involved using automated systems to allow the ATV to track the ISS, moving at 27,000 km/h, and attach itself with an accuracy of 2 cm. Five vehicles were launched before the program ended with the launch of the fifth ATV, ''Georges Lemaître ATV, Georges Lemaître'', in 2014. As of 2020, the spacecraft establishing supply links to the ISS are the Russian Progress spacecraft, Progress and Soyuz spacecraft, Soyuz, Japanese H-II Transfer Vehicle, Kounotori (HTV), and the USA vehicles SpaceX Dragon 2, Cargo Dragon 2 and Cygnus (spacecraft), Cygnus stemmed from the Commercial Resupply Services program. European Life and Physical Sciences research on board the International Space Station (ISS) is mainly based on the European Programme for Life and Physical Sciences in Space programme that was initiated in 2001.

ESA and the EU institutions

The Flag of Europe is flown in space during missions (for example it was flown by ESA's Andre Kuipers during Delta mission). The European Commission, Commission is increasingly working together towards common objectives. Some 20 per cent of the funds managed by ESA now originate from the supranational budget of the European Union. In recent years the ties between ESA and the European institutions have been reinforced by the increasing role that space plays in supporting Europe's social, political and economic policies. The legal basis for the EU/ESA co-operation is provided by a Framework Agreement which entered into force in May 2004. According to this agreement, the European Commission and ESA co-ordinate their actions through the Joint Secretariat, a small team of EC's administrators and ESA executive. The Member States of the two organisations meet at ministerial level in the Space Council, which is a concomitant meeting of the EU and ESA Councils, prepared by Member States representatives in the High-level Space Policy Group (HSPG). ESA maintains a liaison office in Brussels to facilitate relations with the European institutions.


Guaranteeing European access to space

In May 2007, the 29 European countries expressed their support for the European Space Policy in a resolution of the Space Council, unifying the approach of ESA with those of the European Union and their member states. Prepared jointly by the European Commission and ESA's Director General, the European Space Policy sets out a basic vision and strategy for the space sector and addresses issues such as security and defence, access to space and exploration. Through this resolution, the EU, ESA and their Member States all commit to increasing co-ordination of their activities and programmes and their respective roles relating to space.
