The tether sampling method is a new minor-body sampling method proposed by the authors. It consists of three phases; 1) shooting a corer to penetrate the surface of a minor-body, 2) pulling up the corer with tether using a reel mechanism, 3) recovering the corer into a storage box. In this paper, the recovery phase is focused on, and its feasibility under micro-gravity is examined using parabolic flights. The experimental setup and parameters are described in this paper, and the experimental results indicate that the retrieval phase in tethered sampling method is feasible to work under micro-gravity.
