CERN to house, I’ve always chased big questions: Sławosz Uznański

From being a particle physicist with a deep-rooted profession at CERN (European Organization for Nuclear Research) to making ready for a journey to the International Space Station (ISS), Polish engineer and ESA astronaut Sławosz Uznański-Wiśniewski embodies the fusion of science and exploration. Now set to fly on the Axiom-4 mission, he brings expertise from CERN to the challenges of human spaceflight. As Poland’s first consultant on the ISS, very like India’s Shubhanshu Shukla, his mission is not only scientific—it’s symbolic. In an unique interview to TOI, he displays on the intersections between particle physics and house exploration, the calls for of astronaut coaching, and extra.Excerpts:How do you see particle physics and house exploration intersecting sooner or later?With my expertise at CERN, I’ve witnessed how particle physics can drive house exploration. Both fields handle profound questions: what’s the universe manufactured from, how did it start, and what’s its destiny? A key instance is CERN’s Alpha Magnetic Spectrometer (AMS) aboard the ISS, a significant experiment probing cosmic origins. Technologies developed for particle accelerators—particularly in radiation physics—are important for astronaut security on long-duration missions. Materials examined underneath excessive situations at CERN are enhancing spacecraft sturdiness, whereas autonomous techniques developed for advanced experiments are revolutionising distant mission operations. These advances additionally profit Earth—enhancing medical remedies and sustainable know-how. It’s an exhilarating time as innovation flows between science and house.What excites you most about being in ESA’s astronaut reserve & how has it ready you?The most fun half is being on the slicing fringe of house science, collaborating with good minds throughout Europe. My engineering background, mixed with coaching from ESA and scientific work at CERN, has ready me properly for the Ax-4 mission. Every aspect—from analysis to operations—has outfitted me for human spaceflight. It’s a privilege to contribute to such a mission and assist form the way forward for exploration.How do you transition from distant Earth expeditions to challenges in house?Outdoor exploration has taught me resilience, adaptability, and preparation—abilities important for spaceflight. Whether mountaineering or conducting zero-gravity experiments, it’s about staying centered and solution-driven. The endurance constructed on Earth helps me embrace the calls for of house. The drive behind my scientific and exploratory pursuits is identical: a ardour for the unknown. I’ve always chased the big questions.What second impressed your path towards the ISS?One pivotal second was working at CERN on the LHC’s powering techniques, and later, as an Engineer in Charge. Operating the world’s most advanced scientific machine for a worldwide group of researchers was profoundly motivating. Moving into house analysis and ISS collaboration felt like a pure subsequent step. The Ax-4 mission is a continuation of that journey—utilizing science to unlock common mysteries and contribute to one thing bigger than myself.How will your Ax-4 mission affect Poland’s function in house analysis?Poland is steadily gaining momentum in house analysis, and the Ax-4 mission is a milestone. It showcases our scientific potential and evokes funding in STEM. By conducting space-based research, we spotlight Poland’s contributions to worldwide exploration. This mission isn’t nearly science—it’s about inspiring future generations and positioning Poland as a severe house participant. I’m proud to characterize my nation in its first mission to the ISS.
