“This event shows that our technology can transmit not only scientific data, but also human art over long distances,” said ESA Director General, Josef Aschbacher. “It’s a powerful moment that reflects how music – much like space – connects all of humanity.”

Famously used in Stanley Kubrick’s 2001: A Space Odyssey to accompany a spacecraft docking sequence, The Blue Danube has become synonymous with humanity’s exploration of space. With this symbolic mission, ESA honours both a rich cultural heritage and an enduring aspiration: a Viennese waltz echoing endlessly through the Universe.

“The successful realisation of the WALTZ INTO SPACE mission is a testament to Vienna’s unique ability to blend tradition with innovation,” said Norbert Kettner, CEO of the Vienna Tourist Board. “We are proud to have collaborated with the European Space Agency, whose willingness to support this exceptional project is an honour and far from a given. Our sincere gratitude goes to all partners and supporters who made this cosmic celebration of Vienna’s cultural heritage possible.”
