For a decade, the European Space Agency (ESA) and the European Organization for Nuclear Research (CERN) have forged a remarkable partnership, achieving significant milestones in deep space exploration and particle physics research. The Euclid telescope, bolstered by critical technical contributions from CERN, has triumphantly mapped the cosmos. Together, these two organizations have also pioneered new technologies tailored to the unique demands of the space environment, bolstering missions for Earth observation and Jupiter exploration. Additionally, they have spearheaded advancements in space radiation protection technology and empowered startups to commercialize cutting-edge innovations, thereby nurturing the growth of the burgeoning space economy.
