on-the-ground processing is inefficient and even infeasible, depending on the link constraints. Also, if actionable items extracted from raw data are not delivered in time, they may easily become useless in commercial and scientific contexts. Therefore, the recent focus of space agencies, private companies, and research entities aims at taking AI solutions to space to extract and transfer knowledge from raw HSIs acquired onboard imaging satellites.
