Industry Space Days (ISD) are organised by ESA to bring together the main European players in the space sector. Their main purpose is to increase the involvement of SMEs in space activities and to foster cross-fertilisation between the different actors in the entire space sector.

To this end, a series of measures are taken to facilitate networking and the establishing of new business contacts. These include: pre-arranged face-to-face meetings, exhibitions highlighting the innovations and expertise of selected SMEs, briefings on business opportunities by large groups and institutional organisations, and conferences on space perspectives and market trends.
