The future proposed Mars Sample Return Campaign aims to retrieve sample tubes with Martian rock and regolith samples from the Mars 2020 Perseverance Rover and return them to Earth for scientific study. The Sample Receiving Project (SRP) is responsible for receiving and curating the Martian samples. Key technologies were developed to handle the sample tubes and safely remove the samples from the sample tubes within the SRP Sample Receiving Facility (SRF). A preliminary storyboard was defined to deintegrate the Earth Entry System (EES), deintegrate the Orbiting Sample (OS), and remove the sample tubes from the OS. Conceptual designs for a Secondary Outer Containment Case (SOCC), Sample Tube Isolation Container (STIC), Mechanized Puncture Assembly (MPA), Tube Machining System, Chipless Rotary Inline Severer, Linear Actuation Sample Transfer (LAST) mechanism, and remote manipulation Handling System were developed. Prototypes are under development with initial tests performed to determine the leak rate of potential sealing approaches for the SOCC and characterize the forces required for tube puncture, tube cutting, and sample transfer from the sample tube to a Core Dissection Tray Container (CDTC). A model-based systems engineering (MBSE) approach and system architecture framework were established to document and integrate the overall structure and decomposition of system products, functions, requirements, data, I&T flows, and analysis flows.
