“…Taking stock of the effort devoted at ESOC over the last years to the advancement of test automation capabilities, the Automated Regression Testing (ART) [2,3] Framework has been deployed in the E2E GSRF and further advanced to support the automation of tests targeted to assemblies of systems and true replication of user actions performed via system GUI controls [4] to perform Man-Machine Interface Testing (MMIT). This is a real breakthrough towards tests representativeness.…”

The Ground Segment for Mission Operations is a complex System of Systems, including a significant variety of complex elements, often generic and reused across missions, following adaptation to meet mission or family of missions specific requirements and configuration. For such Systems of Systems, the availability of a reference environment where individual ground segment components can be deployed and tested throughout their lifecycle, both at subsystem level and in integrated test chains up to a complete End-to-End Ground Segment, is critical. Also the representativeness of such an environment is critical, in particular the representativeness of the test scenarios with respect to the end-user use cases. At the European Space Operations Centre, the End-to-End Ground Segment Reference Facility has been established as the one-stop environment where the System level Integration and Testing of the Mission Operations Infrastructure takes place. This paper provides an insight into the technical aspects of the End-to-End Ground Segment Reference Facility, the latest achievements, an overview of the remaining challenges and the outlook of its intended evolution.

“…They were not meant to push the state of the art, but only to help satisfy the needs of the MSL EDL systems engineering team while performing V&V. However, researching these topics ex post facto, instances of related solutions published in previous work have been found. Examples of requirements manage ment tools, including the concepts of distributed and concun-ent users and information databasing, have shown up in a wide array of aerospace applications, from the development of helicopters [4] to the planned construction of an international space station [5], Examples of test automation and automated data reduction/analysis are also spread widely throughout the aerospace community, from spacecraft integration and test [6] and automated regression testing of spacecraft mission operations systems [7], to processing of test information during the development of the Boeing 737-300 flight management computer [8] and flight test of naval cruise missiles [9]. This paper summarizes solutions that have been constructed from the same concepts, introduces some new extensions to these ideas, and describes how these solutions were used to enable the successful completion of the MSL EDL V&V program.…”

The Mars Science Laboratory Entry, Descent, and Landing systems engineering team was presented with many challenges in its verification and validation campaign. These challenges arose from both the general complexity of the system architecture and the schedule and resource limitations of the test program. As a result, the team had to accommodate a complex set of requirements, test venues, test objectives, and analysis products. Discussed within are logistical problems faced by the team related to managing these complexities in a portion of Entry, Descent, and Landing verification and validation scope known as the flight system domain. The flight system domain encompassed software-software interactions and system-level software-hardware interactions that happened during the Entry, Descent, and Landing phase of the mission and necessitated the use of flight software and/or flight-equivalent hardware for final verification. The following application-specific solutions were developed to mitigate the complexity-driven problems: methods for functional and priority categorization of verification items (requirements); use of the commercial JIRA software bug-tracking tool for verification item management and closure tracking; development of an automated, configuration-controlled test execution framework; and development of tools for semiautomated test analysis and report management. A list of lessons learned was also developed. Both the solutions and lessons learned can be generalized to other space missions and formidable systems engineering problems, especially those with similar resource-limited constraints.
