Experience gained on applied MBSE at Spaceship FR

The implementation of Model-based Systems Engineering (MBSE) approaches to support systems engineering activities for the design and analysis of space systems is one of the top priorities for many actors in the space sector, such as Space Agencies, Privates Companies, Research Entities, and Small and Medium-sized Enterprises (SMEs). As a result, various organizations have launched initiatives to support the development of knowledge and experience on MBSE practices in a collaborative framework to ensure coordination, even if each actor uses different tools and methods. The French Space Agency (CNES) supports such initiatives by collaboratively and internally working on multiple aspects of MBSE implementation, such as coordinating workshops and discussions around the subject and actively working on technical projects. This short paper summarizes the results and lessons learned from using Capella and the Arcadia Method to perform the Operational Analysis of an Inflatable Lunar Habitat. The Spaceship FR Team at CNES performed this work to understand more about the benefits of MBSE in practice and evaluate its use when working on a collaborative project. In this case, the direct collaborator was a start-up that provided the topic and followed up on the progress of the MBSE activities
