\nOn 21 October 1974, the new European Space Operations Centre, or ESOC, for the first time invited the public inside to see first-hand what was happening at Darmstadt\u2019s mission control centre.\n<\/p>\n
\nAt the time, the centre was part of the European Space Research Organisation, which would, in 1975, be combined with the European Launcher Development Organisation to form ESA<\/a>.\n<\/p>\n \nThe official report in the Bulletin magazine for November 1974 noted:\n<\/p>\n \n\u201cThe interest shown greatly exceeded expectations, as evidenced by the fact that more than 10 000 visitors were catered for between 10.00 and 17.00 hours. With competent staff members acting as guides, tours were arranged through the Operation Control Centre, including the Real-Time and Conversion areas, the Computer Building, and a 210 m2 hall housing life-size models of some of the ESRO satellites and a photo exhibition.\u201d\n<\/p>\n \nWriting in How to Survive in Space<\/a> some 20 years later, author Madeleine Sch\u00e4fer, who worked at the centre until the 1990s, gave the background to what happened:\n<\/p>\n \n\u201c\u2026 over 10 000 visitors from Darmstadt and surroundings descended upon ESOC like a cloud of locusts, avidly devouring everything in their path and leaving a trail of waste and destruction in their wake.\n<\/p>\n \n\u201cDistracted secretaries arriving the following Monday found cupboards, which had been inadvertently left ajar, deplete of everything bearing the ESOC insignia; programmers, who had been foolish enough to leave their programs to run overnight, dejectedly collected the remnants together (the visitors \u2013 not satisfied with the standard PR material \u2013 had selected punch cards at random as souvenirs).\n<\/p>\n \n\u201cDespite competitions, a space quiz, a balloon contest, special playrooms for the children and cinema shows, the Darmst\u00e4dter visitors still found ample opportunity to display a healthy curiosity in all facets of space technology \u2013 by pressing all available knobs and buttons and effectively halting the mainframe computer and all on-going operations.\u201d\n<\/p>\n \n\u201cAll in all, the first Open Day was pronounced by all participants to be a wonderful success.\u201d\n<\/p>\n \nThe next open day at ESOC, \u201cLong Night of the Stars\u201d<\/a>, is set for 8 September 2017, to celebrate the centre’s 50th anniversary.\n<\/p>\n \nMore information<\/b>\n<\/p>\n \nhttp:\/\/www.esa.int\/esoc50<\/a>\n<\/p>\n \nMore images via Flickr<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" \nOn 21 October 1974, the new European Space Operations Centre, or ESOC, for the first time invited the public inside to see first-hand what was happening at Darmstadt’s mission control centre.\n<\/p>\n \nAt the time, the centre was part of the European Space Research Organisation, which would, in 1975, be combined with the European Launcher Development Organisation to form ESA<\/a>.\n<\/p>\n \nThe official report in the Bulletin magazine for November 1974 noted:\n<\/p>\n \n“The interest shown greatly exceeded expectations, as evidenced by the fact that more than 10 000 visitors were catered for between 10.00 and 17.00 hours.
