The invention discloses a high-functional-density micro-nano satellite for monitoring low-orbit space debris. The satellite is composed of a turn-back type optical integrated structure, an expandable double-layer film sensor, a satellite-borne real-time processing system, a solar panel and a modular CubeSat component. The turn-back type optical structure comprises a satellite 3U main frame and an optical system and forms a main body structure of the satellite, one third of the main body structure is the turn-back type optical structure, the design ensures that the proportion of the optical system is maximized in a limited volume, and a large field angle and high optical observation capacity are achieved; the expandable thin film sensor is stored in a cubic satellite body, after a satellite enters an orbit, the expandable thin film sensor is released, expanded and used for monitoring space tiny dust, the folding-unfolding ratio is large, and the expandable thin film sensor is suitable for the limited space of a micro-nano satellite; the satellite-borne real-time processing system is composed of a core processor and a peripheral circuit and has real-time image processing and data downloading capabilities; and the other components jointly maintain the attitude stability and normal operation of the satellite.
