Trans-Global Mission Architectures
Mission operations include the utilization of both space and ground resources to achieve mission objectives. Future architectures will make the spacecraft a node on a distributed system, thus expanding the scope of missions beyond the global scale. The history and evolution of planetary mission operations are outlined, together with the current global involvement in planetary missions. The modular nature and reuse of the supporting ground data systems, and the inclusion of automation and dedicated software in space missions, are discussed. A trans-global mission architecture is presented, and consists of an extension of a layered reusable mission operations architecture to create an open ground/space operations system. Concurrent mission engineering with such trans-global structures is discussed.
