ESA Historical Timeline


24-25 October 1961: At its third session in Munich, the Commission Préparatoire Européenne de Recherche Spatiale (COPERS) approves the Blue Book, a  77-page report specifying  the main features of a future European space research organisation.  The main facility should be an engineering centre responsible for the engineering of satellites and large scientific payloads. These activities were to be undertaken by what was initially called a Payload Engineering Unit and, later, the European Space Research and Technology Centre (ESTEC). It was also suggested that a central  data analysis centre should be established, in addition to the tracking and data facilities which would be required.  
The European Launcher Development Organisation (ELDO) and the European Space Research Organisation (ESRO) are established (the charters of the two organisations will be two years later, in 1964). These two organisations were the predecessors to ESA.
29 February 1964: ELDO Convention enters into force
20 March 1964: ESRO Convention enters into force
June 1964: The first formal steps towards placing senior scientific staff in ESLAB are taken. At this time, the plans for the sounding rocket programme and the payloads for the first two small satellites, ESRO I and ESRO II, are well under way. NASA offered to launch these first two satellites with a Scout rocket free of charge as a "christening gift" for ESRO.
19 February 1965: Redu, located in the heart of the Belgian Ardennes, is selected to be one of the four ground stations of the ESTRACK network to track ESA satellites
29 May 1967: The ESRO II launch, at the Western Test Range,  fails.
6 June 1967: France and Germany agree to jointly develop the experimental communications satellite Symphonie.
11 July 1967: The second ESC takes place in Rome. Creation of the Causse Committee to work out a coherent European space programme. ESRO is requested to design a television-relay satellite meeting the needs of the European Broadcasting Union (EBU)
31 December 1967: The Redu station is declared operational
The European Broadcasting Union (EBU) approves Eurafrica satellite. It represented an important step forward in relation to previous American satellites as well as to Symphonie.  It sophisticated three-axis stabilisation to keep the satellite firmly oriented towards the Earth, but its solar cell array was not designed to track the Sun. The Eurafrica design, on the contrary, adopted "four-axis" stabilisation, namely three-axis stabilisation of the body of the satellite and Sun-pointing solar array.820 Other characteristics, like a longer operational life (5 years), a higher power output, and a less expensive earth station, made Eurafrica a kind of prototype of an operational satellite designed to meet the requirements of a well-defined client.
17 May 1968:  ESRO II, first satellite tracked from Redu Station.
29 May 1969: As a part of the Aerosat programme, an ad hoc air traffic control expert group is set up by ESRO, with the goal of establishing an air traffic control system based on geostationary satellites by the end of the decade.
November 1969: The European Space Conference is held in Bad Godesberg (DE) during which it was proposed forming a single European organisation with ELDO, ESRO, and Conference CETS.
November  1971: The Memo of Understanding between NASA and ESRO is signed. It concerns deployment of a four-satellite system for air traffic management, two over the Atlantic ocean, two over the Pacific.
December 1971: Agreement on the First Package Deal, with three applications programmes to be executed in parallel:
  • Communications Satellite Programme
  • Aeronautical Satellite Programme
  • Meteorological Satellite Programme
As part of this, the Support Technology Programme (STP) is the first dedicated to telecoms satellites. This programme was succeeded by ASTP.
31 October 1972: first meeting of ESRO's Aero Programme Board, in Neuilly.
November 1972: The Programme Board for Telecommunications (PB-TEL)  adopts the OTS concept, which is based on a new satellite development.
April 1973: Delegates from Belgium, Denmark, France, Germany, Sweden and Switzerland, and the UK confirm readiness to participate in the Telecommunications Programme. Italy joined in September. Its objectives are: To design, develop, construct, and set up the experimental and pre-operational space segment of a  space communications system matching the objectives of the users, and to make reliable operational satellites available to the users on the completion of the programme.
12 and 31 July 1973: In the Second Package Deal, the Marine Orbital Test Satellite(Marots) programme is approved. This which will result in the development of an experimental satellite for maritime communications based on the OTS platform, with launch planned 1977.
12 September 1973: First meeting of new Interim Maritime Satellite Programme Board, Neuilly. Belgium, Denmark, France, Germany, Italy, the Netherlands, Spain, Sweden, and the UK.
The Telecommunications office is established at ESA.
15 April 1975: At the final ESC meeting in Brussels, a convention is adopted to set up the European Space Agency (ESA), effectively merging ESRO and ELDO, and broadening the scope of the agency’s remit to include operational space applications systems such as telecommunications satellites.
30 May 1975: Belgium, Denmark, France, Germany (the Federal Republic), Italy, the Netherlands, Spain, Sweden, Switzerland and the United Kingdom sign the Convention establishing ESA.

14-15 February 1976: ESA Council meeting in Paris at ministerial level passes inter alia a Declaration to undertake an overall communications satellite programme and a resolution creating the Earthnet programme.
March 1976: Agreement among ESA and a number of national PTTs whereby the latter would set up a network of 20 to 25 earth stations to provide trunks for international telephony and for Eurovision.
As part of the a Telecommunications Package Deal, the follow-up to the STP, the Advanced Systems and Technology Programme (ASTP) is  inaugurated. The ESC extension and H-Sat are also agreed upon. ASTP was later merged into the ARTES programme, mostly in ARTES 5.

16 July 1979: International Maritime Satellite Organization (Inmarsat), a not-for-profit international organization, set up at the behest of the International Maritime Organization (IMO), a UN body, for the purpose of establishing a satellite communications network for the maritime industry. It was converted into a private company in 1999.
24 September - 6 December 1979: First World Administrative Radio Conference takes place in Geneva, Switzerland. Representatives of ITU Member countries adopted the new Radio Regulations. Of the approximately 15,000 proposals put forth 12,000 concerned frequency allocation. The resulting Final Acts of the conference comprised of a volume of more than 1,000 pages.

Skybridge is planning to begin construction of its 80-satellite system in late-1999 with the signing of construction and launch contracts worth US$4.8 billion. Once in full production, the system will cost US$150 million per month. Skybridge would launch services in 2002, providing over 200 Gbits/sec of overall system capacity.
