“…Various architectures for OS capture systems were proposed and studied over the past 20 years. [68][69][70][71][72] An early concept for the COM is shown in Therefore, a level of autonomy is required for the COM to achieve its goals while operating independent of ground control. This autonomy could be in the form of pre-planned sets of instructions transmitted to the spacecraft and executed by the CCRS Command and Data Handling (C&DH) system.…”

This study compares the types and quantities of knowledge that are captured by a model-based systems engineering (MBSE) approach and a traditional architecting approach to measure the benefits of the MBSE approach in managing the complexity of a robotic space system. The MBSE approach was implemented with Cameo Systems Modeler using Systems Modeling Language (SysML) and applied to architecting an orbiting sample Capture and Orient Module (COM) system concept for a Capture, Containment, and Return System payload concept for potential Mars Sample Return.An architecture framework was established, covering system, subsystem, and assembly levels, along with structure, behavior, data, and requirements perspectives. The COM system architecture was captured in parallel using both the MBSE and non-MBSE approaches in order to provide a side-by-side comparison of the approaches.The approaches were evaluated based on how well each represented the information content of the COM system architecture. A total of 4389 knowledge elements were classified using the Revised Bloom's Taxonomy knowledge dimension and used to quantitatively compare the two approaches. The MBSE approach more completely captured architectural knowledge than the non-MBSE approach. Limitations to the SysML-based MBSE approach were also identified, including its ability to fully represent certain high-level conceptual, procedural, and metacognitive knowledge such as design principles, design approaches and rationales, risks, development strategies and rationales, organizational core competencies, and requirement verification methods.The overall results demonstrate the benefits of MBSE in managing the complexity of robotic space systems and strengthen the case for adopting MBSE within the systems engineering community.

“…This work examines the relevant dynamic metrics of an FPI designed to capture a notional spherical orbiting sample cache (OS) that is a maximum of 12.5 kg [21]. For this proposed flux-pinning application, 12 magnets were mounted on the surface of the orbiting sample evenly on the perimeter of the 20.3 cm diameter sphere.…”

Flux-pinned interfaces for spacecraft leverage the physics of superconductor interactions with electromagnetism to govern the dynamics between two bodies in close-proximity. Several unique advantages over traditional mechanical capture systems include robustness to control failures, contactless reorientation of the capture target, and collision mitigation. This study describes a series of experiments performed in a microgravity environment during a parabolic-flight campaign to measure the dynamic behavior of a flux-pinned interface in a flight-traceable environment. This paper presents the performance of a flux-pinned interface in the full six degrees of freedom in terms of several quantifiable metrics: success of capture at various energetic states, momentum change, system damping, and interface stiffness of the two spacecraft bodies.
