Click on the boxes below for mission summaries, links and meetup details. You can filter by:
- Domain – This is the broad category that the mission falls under. OpenAir domains include R&D (making things and citizen science), Advocacy (CDR policy development and activism), Activist Business Development, or ‘Biz Dev’ (supporting CDR projects, companies and general sector development), Knowledge (shows, content and activities that are educational), and Culture Making (Creative work inspired by CDR subjects).
- Status – This tells you what stage the mission is at. Concept missions are at a planning stage of development, usually with a few people involved who are looking for co-founders and core members. In Progress missions are, well, in progress – already meeting up regularly and implementing their core activities. Completed missions have either achieved their end or are on hiatus and are not currently active.
