European Space Research Organisation


The European Space Research Organisation was an international organisation founded by 10 European nations with the intention of jointly pursuing scientific research in space. It was founded in 1964. As an organisation ESRO was based on a previously existing international scientific institution, CERN. The ESRO convention, the organisations founding document outlines it as an entity exclusively devoted to scientific pursuits. This was the case for most of its lifetime but in the final years before the formation of ESA, the European Space Agency, ESRO began a programme in the field of telecommunications. Consequently, ESA is not a mainly pure science focused entity but concentrates on telecommunications, earth observation and other application motivated activities. ESRO was merged with ELDO in 1975 to form the European Space Agency.

Foundation

European Preparatory Commission for Space Research

The origins of a joint European space effort are generally traced back to a number of initiatives taken in 1959 and 1960 by a small group of scientists and science administrators, catalysed by two friends, physicists and scientific statesmen, the Italian Edoardo Amaldi and the Frenchman Pierre Victor Auger. Neither Amaldi nor Auger was a stranger to the cause of scientific collaboration on a European scale. Indeed, it was they who, in the early 1950s, were key actors in the process which led to the setting up of CERN, the European Organization for Nuclear Research.
Now, as the decade drew to a close, they turned their attention to space. Success was rapid. Within a year of the first formal discussions being held amongst scientists, European governments had set up a preparatory commission in order to explore the possibilities for a joint space research effort.
The European Preparatory Commission for Space Research held its first session in Paris on 13 and 14 March 1961. Its first task was to create the organs needed to define the scientific programme and the necessary infrastructure of the envisaged organisation, to draw up its budget, and to prepare a Convention for signature by those member state governments who wished to join it. To this end the meeting first elected its "bureau": chairman Harrie Massey, vice-chairmen, Luigi Broglio and Hendrik van de Hulst, and executive secretary Pierre Auger, all men who had played an important role in the debates in 1960 and, Auger apart, still active and eminent European space scientists. It then established two working groups.
The first was the Interim Scientific and Technical Working Group and its task was to prepare the scientific programme for the future space organisation, paying particular attention to the technical and financial implications of its proposals. Lamek Hulthén, from the Royal Institute of Technology in Stockholm, was nominated chairman of this group; Reimar Lüst from the Max Planck Institute for Physics in Garching, Germany was appointed its coordinating secretary.
The second was the Legal, Administrative and Financial Working Group. Its chairman was initially left open, though it was recommended that he be someone from the German Federal Republic. Alexander Hocker, a senior bureaucrat from Bad-Godesberg who was the chairman of the CERN Finance Committee at the time, took on this task. All Member States were to be represented on both working groups, which were empowered to set up subgroups to facilitate their work.

The Blue Book

By the third meeting of COPERS on 24 and 25 October 1961 in Munich, the Interim Scientific and Technical Working Group had prepared a 77-page document outlining the future European Space Research Organisation. The so-called "Blue Book" was divided into five parts, each devoted to one of the following subjects:
  1. a general outline of ESRO
  2. ESRO's scientific programme
  3. its technology centre
  4. data handling
  5. ranges and vehicles
The Blue Book foresaw the firing of some 435 sounding rockets and the successful development and launching of 17 satellites in the 8 years covered by the ESRO Convention, namely 11 small satellites, 4 space probes, and 2 large satellites. It was assumed that 2 launchings would be required to orbit one successful spacecraft, so the number of satellite and space probes launchings budgeted for was doubled. The total cost of the satellite programme was estimated at 733.5 million ₣, of which 450 million ₣ was for launchers and launch operations and 283.5 million ₣ for spacecraft development.
The Blue Book was more a manifesto of interests and expectations than a concrete working hypothesis. It only reflected the intentions and hopes of important sectors of the European scientific community while ignoring their lack of capacity to fulfill these intentions. The fact that transforming the manifesto into a true operational programme would be a long and laborious process and the results sometimes disappointing.

Organisation and functioning

The ''Auger years'' (1964–67)

The ESRO Convention entered into force on 20 March 1964. The ten founding states were Belgium, Denmark, France, Germany, Italy, Netherlands, Spain, Sweden, Switzerland and the
United Kingdom. Two other countries which had participated in the early COPERS activities, Austria and Norway, decided not to join the new organisation but retained an observer status. The first
meeting of the Council opened in Paris three days later with Harrie Massey in the chair. Pierre Auger was appointed ESRO's first Director General.

Legislative arm

At the decision making level, the supreme governing body was the council, made of delegations from its Member States. Each member state had one vote in the council, where it could be represented by not more than two delegates, one of whom was generally a scientist, the other an important national science administrator. One or more advisers were usually included national delegations. The main tasks of the council were to determine the Organisation's scientific, technical and administrative policy; to approve its programme and annual work plans; and to determine its level of resources both annually, and every third year for the subsequent three-year period. The council was advised by two subordinate bodies, the Administrative and Finance Committee and the Scientific and Technical Committee.

Executive arm

At the executive level, ESRO was managed by a Directorate based in Paris, including the Director General assisted by a Scientific Director, a Technical Director and a Head of Administration. The directors of ESRIN, ESDAC and ESLAB reported to the Scientific Director; the director of ESTEC, who had also responsibility for ESRANGE and ESTRACK, reported to the Technical Director. The "Executive", as it was eventually called, was responsible for the implementation of approved programmes within the established financial envelope and under general control from the Scientific and Technical Committee. It was also called to perform feasibility studies of space missions proposals coming from the scientific community and recommended by the STC, in view of their eventual adoption in the programme.

The ''Bannier report'' and its consequences

Only two years after the formation of ESRO, problems with its structure became painfully obvious. By mid-1966 it had climbed to 50%, placing enormous pressure on the operational programme. For this reason the Council set up a group of experts led by J.H. Bannier to investigate and solve the problem. Bannier quickly relieved the pressure on the AFC by raising the limit below which the Executive could award contracts without having to seek committee approval. He further increased the role of the Executive by transferring certain competencies from the Legislative to the Directorate. But this was only a stop-gap measure.
Bannier realised that the entire structure of ESOC had to be changed. Firstly, they were emphatic that the executive function of the organisation should be clearly separated from the policy and the planning function. Secondly, as far as the scientific programme was concerned, they recommended that there be a clear institutional distinction drawn between spacecraft development and spacecraft operation after launch. To achieve these objectives, the Bannier group suggested that ESRO's top management structure be completely changed. The dichotomy between scientific and technical directorates was, in Bannier's view, wrong in principle for an organisation like ESRO. To overcome it, he suggested that the two posts be abolished. In its stead a new structure was proposed. It comprised the Director General plus four directors, two of whom were essentially responsible for policy-making and two for policy execution. A new post was to be created in the first category, a so-called Director of Programmes and Planning, whose task it would be to prepare draft programmes of the Organisation, based on the scientific, technical, financial and time implications of the different proposals. The second member of the directorate concerned with forward planning would be the Director of Administration whose task it would be to prepare policy on the future needs of personnel, finance and contracts, and to organise and implement the necessary procedures to maintain an a posteriori control over the Organisation's functioning. The two posts in the Directorate having executive authority would be filled by the director of ESTEC and of ESDAC, which was to be renamed ESOC, the European Space Operations Centre. As for ESRIN, the Bannier group judged its research to be marginal to the major activities of the Organisation. Its director, they felt, should not be a member of the directorate but should rather report directly to the DG.

Facilities and establishments

European Space Research and Technology Centre

The European Space Research and Technology Centre was to be a facility at the very core of ESRO. Its responsibilities included the engineering and testing of satellites and their payloads, the integration of scientific instruments in these payloads, and making arrangements for their launch. In some cases member states were to produce the scientific instruments for ESRO or produce them as part of their own national effort and compensate ESTEC for its service. In practise, national organisations simply used ESTEC as a service organisation and left it to pay for their efforts from the ESRO budget.
After the Bannier Report the facility gained overall executive authority for spacecraft development and was merged with ESLAB. The satellite control centre was also moved to ESOC. ESTEC was originally to be located in Delft but because of unforeseen difficulties, Noordwijk was chosen instead.
