Space-based systems were a significant portion of the early literature on solar geoengineering, but space-based methods have been all-but ignored in the last decade as geoengineering research grew. We convened an informal meeting to consider this topic at Harvard on November 25th, 2019. The attendees were scientists, scholars, writers and entrepreneurs primarily from the US and Europe, with interests in both the development of space and solar geoengineering. The aim was to discuss the two communities’ priors on this subject: that space-based approaches aren’t plausible (solar geoengineering) and that geoengineering is not an interesting application of space-based industry (space development). The goal was to say, on re-examination, whether those priors were justified and, to the extent that they might not be, to ask what level of discussion and what sort of research agenda might usefully follow.
