Day 105, orbit 1629 \u2014 This accelerated video shows the installation of MatISS-4, a French experiment that aims to collect and study the biocontamination of the air inside the European Columbus module. Biocontamination \u2013 such as small skin cells, droplets from sneezes or saliva, and bacteria \u2013 is unavoidable, so we make sure to clean surfaces every week (I\u2019ll publish a housekeeping timelapse soon!), but some areas are particularly hard to reach\u2026<\/p>\n
Over 10 years, MatISS has shown that the Station\u2019s systems are very efficient; after several months of exposure, the contamination level inside the MatISS cases remains low. MatISS-4 features a new design, which will allow the contaminated membranes to be analysed at the European Synchrotron in Grenoble using an X-ray nano-imaging instrument. Go science! <\/p>\n
MatISS has also enabled researchers to identify surfaces that are more resistant to biocontamination, opening up many applications on Earth: in public transportation, where thousands of people touch the same surfaces every day, in places where limiting contamination is key, such as hospitals, cruise ships, and submarines, and even in livestock farming. Less biocontamination = less cleaning with chemical products! <\/p>\n

Jour 105, orbite 1629 \u2013 Cette vid\u00e9o acc\u00e9l\u00e9r\u00e9e montre l\u2019installation de MatISS\u20114, une exp\u00e9rience fran\u00e7aise qui vise \u00e0 collecter et \u00e9tudier la biocontamination de l\u2019air \u00e0 l\u2019int\u00e9rieur du module europ\u00e9en Columbus. La biocontamination \u2013 cellules de peau, \u00e9ternuements, postillons, bact\u00e9ries \u2013 est in\u00e9vitable. Nous nettoyons les surfaces chaque semaine (je publierai bient\u00f4t un timelapse de m\u00e9nage\u202f!), mais certaines zones sont particuli\u00e8rement difficiles d\u2019acc\u00e8s\u2026<\/p>\n
Depuis plus de 10 ans, MatISS d\u00e9montre que les syst\u00e8mes de la Station sont tr\u00e8s efficaces ; apr\u00e8s plusieurs mois d\u2019exposition, le niveau de contamination \u00e0 l\u2019int\u00e9rieur des bo\u00eetiers reste faible. MatISS\u20114 pr\u00e9sente un nouveau design, qui permettra d\u2019analyser les membranes contamin\u00e9es \u00e0 l\u2019aide d\u2019un instrument de nano-imagerie X du synchrotron europ\u00e9en de Grenoble. Vive la science\u202f!<\/p>\n
MatISS a \u00e9galement permis aux chercheurs d\u2019identifier des surfaces plus r\u00e9sistantes \u00e0 la biocontamination, ouvrant la voie \u00e0 de nombreuses applications sur Terre\u202f: dans les transports publics, o\u00f9 des milliers de personnes touchent les m\u00eames surfaces chaque jour\u202f, dans les lieux o\u00f9 limiter la contamination est essentiel, tels que les h\u00f4pitaux, les navires de croisi\u00e8re et les sous\u2011marins, et m\u00eame dans les \u00e9levages. Moins de biocontamination = moins de nettoyage avec des produits chimiques !<\/p>\n
