3. CSAGI (Comité Spécial de l'Anneé Géophysique Internationale). International collaboration in science had been fostered during the twentieth century by the growth of International Scientific Unions. When CSAGI was established there were 16 of these unions effectively covering nearly all scientific disciplines. Although there had been political exclusions in 1952 any nation with scientific activities of any significance had been without question an adhering member with the national scientific organizations (in the UK this was the Royal Society) providing the financial support for the work of the international body.
4. ‘A steerable radio telescope’ a collection of papers describing the proposal written by B. Lovell J. A. Clegg and J. G. Davies (the ‘Blue Book’) deposited in the University of Manchester John Rylands Library.
5. Dr John P. Hagen the radio-physicist in the Naval Research Laboratory who was appointed director of the Vanguard project subsequently described some of the unbelievable difficulties that the project faced. The most revealing of these was that the Army turned down his request to be allowed to use its rocket testing pads at Cape Canaveral on the grounds that this would interfere with their missile test programme. The Vanguard team therefore had to build its own launch complex and blockhouse for which no funds had been provided. This construction work took one and a half years.
