Special opening – Hommage Jubilaire à Pierre Auger | ESA Archives Portal
While we celebrate 50 years of ESA in 1975, the real ‘genesis moment’ for European space can be traced back to 1959, and the initial conversations between two celebrated physicists with a shared vision. This special opening of proceedings from a symposium in honour of one of them - Pierre Auger - sheds new light on these beginnings, on the careers, networks and cooperation of these pioneers and on the fulfilment of their work, which would eventually lead to the creation of ESA.
