How to Architect Family of Complex Space Systems and Networks?

  1. 1. Systems Architecture Products Capturing SCaN Legacy Networks in Architecture Diagrams and Documents Constellation Orion-to-ISS Mission NASA Lunar Mission and Communication Networks SCaN Future Architecture “Architecture is a creative art, even if it is based on an existing legacy system. It is not only for engineering or construction guidance, but it also has to provide insight, intent, and vision, so that it can guide the system in moving forward through continual evolution.” Dr. Yan Zhao; CGI Federal Director for Enterprise and Solutions Architecture 1
