Abstract This paper provides a review of the main issues affecting satellite survivability, including a discussion on the technologies to mitigate the risks and to enhance system reliability. The feasibility of a 100-year lifespan space mission is taken as the guiding thread for the discussion. Such a mission, defined with a few preliminary requirements, could be used to deliver messages to our descendants regardless of the on-ground contingencies. After the analysis of the main threats for long endurance in space, including radiation, debris and micrometeoroids, atmospheric drag and thermal environment, the available solutions are investigated. A trade-off study analyses orbital profiles from the point of view of radiation, thermal stability and decay rate, providing best locations to maximize lifespan. Special attention is also paid to on-board power, in terms of energy harvesting and accumulation, highlighting the limitations of current assets, i.e. solar panels and batteries, and revealing possible future solutions. Furthermore, the review includes electronics, non-volatile memories and communication elements, which need extra hardening against radiation and thermal cycling if extra-long endurance is required. As a result of the analysis, a century-lifetime mission is depicted by putting together all the reviewed concepts. The satellite, equipped with reliability enhanced elements and system-level solutions such as smart hibernation policies, could provide limited but still useful performance after a 100-year flight.
