Europe’s largest place for space is little visited, but hugely influential: this October you get the chance to see for yourself. ESA’s technical centre ESTEC is opening its doors to the public – a must for all space enthusiasts. <br /> <br />Mark your calendar: this year’s ESTEC Open Day will take place on Sunday 4 October – the 58th anniversary of the launch of Sputnik-1 – as part of the Netherlands’ national Weekend of Science and World Space Week. <br /> <br />This is your chance to meet astronauts and space experts, tour key facilities and examine actual space hardware in close-up. This year’s event will focus on our longer-term space future, highlighting new technologies being developed to change the space industry state-of-the-art, and the new destinations being opened up in the process.
