    12. Plasma Kristall-4: la matière dans tous ses états

      Publishing date:

      July 1, 2021

      Du 20 au 26 juin 2021, une partie de l’équipe d’ingénieurs du CADMOS, centre opérationnel du CNES dédié aux activités en micropesanteur, a travaillé 24h/24 aux opérations de l’expérience Plasma Kristall-4. Issue d’une collaboration ESA – Roscosmos, cette expérience de physique fondamentale permet de mettre en évidence le comportement des plasmas complexes en micropesanteur et de valider des modèles physiques sur Terre. De nombreuses applications existent dans les domaines de l'automobile, de l'industrie ou encore de la santé.
