PROJECT DESCRIPTION

This project presents the design of a sample acquisition device for a potential future mission to 16 Psyche. The work focuses only on the acquisition system: a mechanism that can collect and securely store surface samples in an extreme space environment. The final design uses a piezoelectrically actuated drill on a robotic arm to core surface material. Hollow coring bits retain the sample inside the bit, reducing handling and lowering the risk of loss or contamination. Each bit attaches electromagnetically to the drill for simple exchange, then is placed into an individual storage compartment. Upper and lower grommets hold drill bits securely, protect collected samples, and reduce dust intrusion. Structural and fatigue analyses showed that the design can withstand expected loading and vibration while maintaining sample security. Overall, the system provides a compact and practical solution for sample acquisition and storage on 16 Psyche.
