The nano-satellites after the end-of-life, which become the orbital debris, can be a threat to the other spacecrafts, especially in low Earth orbit (LEO). NASA, the DOD, JAXA, and other space agencies have been making action to the debris issue of the nano-satellites, i.e. requesting the developers of new nano-satellites to comply with the 25-year post-mission orbital lifetime restrictions. To enable the compliance with the restriction, the atmospheric-reentry is the most available method for the nano-satellites in LEO. In this paper, we will present the conceptual study on the de-orbit module for a 50kg-class micro-satellite. The proposed deorbit module is the light-weight panel structures with simple mechanisms, which is activated when the mission is completed, and deploys the panel structure. Then, the altitude of the satellite will get descent by the aerodynamic drag acting upon the panels.
