O-ZONE Team was born from a group of students from Padua. They participate at the REXUS/BEXUS project (http://rexusbexus.net) of SNSA (Sweden National Space Agency) and DLR (German Space Agency) in close collaboration with ESA (European Space Agency). Thanks to a balloon (BEXUS), the students will be able to launch their device for the sampling of air pollutants at a height of 30,000 meters. In addition to being about space activities (interesting argument), the project aims to develop sensitivity and intervention to the problem of air pollution and its serious repercussions, more topical than ever.
