Space Missions: Near-Earth Objects, Samples

Scientific paper

Recent studies suggested that even relatively small asteroids preserve considerable amount of regolith. Yet it is still not possible to fully understand their surface conditions only from ground observation. Thus we have developed a single sampling device that suits from metal-silicate hard surfaces to regolith layers for MUSES-C, the world's first sample return mission to a near Earth object. We report its mechanism and sampling sequence, together with results of sampling efficiency tests for 1G and micro-G gravity levels. In the vacuum micro-G environment, each sampling with this device promises several hundred mg to several g of target material fragments collected.
