We consider the problem of downloading observa-tions for a next-generation agile Earth-observing satellite. The goal is to schedule file downloads during ground re-ception station visibility windows while minimizing infor-mation age and promoting the fair sharing of the satellite between users. It is a complex scheduling problem with constraints ranging from unsharable resources to time-dependent processing times. Usually, planning and sche-duling are done on the ground but in our case, data vo-lumes are unpredictable and we propose to share decision-making between the ground and the onboard software, which allows us to take decisions knowing the data vo-lume onboard while keeping a fair level of predictabi-lity on the ground. We develop several levels of flexibi-lity, a decision-making architecture and compare these ap-proaches on realistic scenarios.
