Earth from space - Claude Nicollier's keynote at the 29th Dies academicus

Professor Claude Nicollier, the first and so far only Swiss astronaut to travel to space, was interviewed by Giovanni Pellegri, Head of L'ideatorio at USI, during the 29th Dies academicus. Their conversation was intense and insightful, as they recounted the key moments of Nicollier's life and career, blending science, emotions, and reflection.

From his early childhood dreams - fuelled by his grandfather's telescope - Claude Nicollier recounted how his passion for astronomy led him to an extraordinary personal and professional journey. He shared with the audience his feelings and the lessons he learned during his missions in space, discussing the view of Earth from orbit, the importance of international collaboration, and how this unique perspective influenced his understanding of the world.

A central moment of the interview was devoted to the link between space and USI. Nicollier highlighted that the space industry provides professional opportunities across various fields, including informatics, medicine, and communications. He underscored USI's commitment to promoting these careers through its collaboration with Space Exchange Switzerland (SXS). Additionally, he mentioned the significance of IRSOL and USI's three planetariums, which serve as venues where science and education unite to inspire new generations.

He explained that observing the sky is not only a scientific endeavour but also a deeply meaningful human experience. In a particularly moving moment, he shared what it means to watch the sky with his grandchild today. This act encourages us to reflect on our place in the universe and reminds us of our responsibility to care for our planet.

To close the interview, Nicollier shared a message of hope from the book co-written with Abbé Dominique Rimaz and cartoonist Derib, inviting the younger generations to follow their passions and seek their place in the world with curiosity, courage and awareness.
