Sunday 8 October is when ESA opened the doors of its largest establishment this year, letting visitors meet astronauts and space experts, talk to the teams behind Europe’s space missions and inspect a unique concentration of space simulation and test facilities.
This is the centre’s seventh annual Open Day, set to be the biggest yet, with the theme of Bringing Space To Earth. A record eight astronauts will be speaking and signing autographs: Jean-Jacques Favier and ClAudie Haigneré of France, Michael Foale of the UK, Dirk Frimout of Belgium, Ulf Merbold and Ernst Messerschmid of Germany, Dumitru-Dorin Prunariu of Romania, and André Kuipers of the Netherlands.
