The crew left Earth on 25 June for the International Space Station (ISS) aboard the same spacecraft that returned them safely to terra firma. During his ESA (European Space Agency) mission Ignis, Sławosz conducted 13 experiments proposed by Polish companies and institutions and developed in collaboration with ESA, along with three additional ESA-led experiments. These covered a broad range of areas including human research, materials science, biology, biotechnology and technology demonstrations. While in the ISS, Sławosz also tested a CERN technology, the SpaceRadMon-NG (SRM), a radiation monitoring device, developed in 2024 in collaboration with the Polish start-up SigmaLabs. We are delighted that Sławosz is back with us – congratulations on a very successful mission! We wish him all the best for his return home and hope to see him at CERN soon. CERN’s Hardronic Festival: wouldn’t miss it for the world! On 12 July, CERN’s legendary Hardronic Music Festival took place on the terrasse of Restaurant 3, in Prévessin. Created in 1989, the festival is an opportunity for CERN people, friends and families to come to the site and enjoy live music and delicious food. Nobody – nobody – wants to miss this event, and being on board the ISS didn't deter Sławosz:
