The purpose of the Space Systems Challenge team is to explore the use of MBSE in Space Systems and provide real world cases and examples of MBSE for Space Systems. This applies to both Systems that Fly in Space as well as the ground systems that control and communicate with space assets.

While much of the early MBSE initiative centered around SysML, this teams vision has conformed with the MBSE initiative of realizing MBSE with SysML being an enabler. Thus another aspect of the purpose of this team is helping define a path to MBSE that incorporates the newer technologies in terms of languages with existing methods and modeling techniques.

The Charge of the Challenge Team is changing its focus. Given the successes of FireSAT and other challenge teams and pilots done within NASA, our challenge now is to reach out further to practitioners and develop case studies for the results that MBSE achieves with used in actual projects.

Measure of Success

  • Represent Space Systems with Systems Models
  • Generate Systems Engineering Products from Models
    • * Documents and Reports
    • * Analysis of Models
  • Identify Limitations and Areas of Improvement for MBSE Methods, languages and Techniques
  • Systems Models as Integration with other Engineering disciplines
    • * relationship between sophisticated domain models and simulation and SE products
    • * increase fidelity and integrity of SE products
    • * understand impacts of change
  • Show benefits of MBSE in space systems projects
    • * Greater consistency of work products
    • * Reduced re-work effort
    • * Earlier identification of defects
    • * Better technical information support to operators

Topic Overview / Description

The Space Systems Challenge Team began with the Space Mission Analysis and Design text book as a source of broad industry knowledge and consensus. The FireSAT models are open and sharable in terms of ITAR and export issues.
