Such a base will require a supply chain to keep the occupants alive and well. This project explores the structure of such a supply chain using a tool built for the task called SpaceNet. Introduction On January 14, 2004, President George W. Bush announced a new vision for NASA and the human exploration and development of space. In an address to NASA Headquarters in Washington, DC, the President stated that the "new course for America's space program" would give NASA a new focus and clear objectives for the future. "We do not know where this journey will end," said Bush, "yet we know this: Human beings are headed into the cosmos." The goals Bush set for NASA in the coming decades included the following: Complete construction of the International Space Station (ISS) and retire the Space Shuttle by 2010. Develop a Crew Exploration Vehicle (CEV) to replace the Space Shuttle as the new workhorse for the Human Exploration and Development of Space (HEDS). Develop a Lunar Surface Access Module (LSAM) for human lunar exploration. Return American astronauts to the moon by 2020 to explore and exploit the potential of its resources for long term permanent human presence. To explore supply chain management for this goal, NASA commissioned the Massachusetts Institute of Technology (MIT) to develop SpaceNet. This modest, first generation freeware program models interplanetary supply chains. SpaceNet uses MATLAB and Excel together as its calculation backbone. It has a graphical user interface and allows the user to select elements and nodes and to specify end demands. It sets up, but does not solve, optimization problems. It requires external packages such as CPLEX or SYMPHONY to execute actual optimizations.

SpaceNet relies on an Internet Supply Chain Management (ISCM) flowchart page that includes the following information and diagram: The SpaceNet software is a simulation and optimization tool that captures the concepts and ideas related to interplanetary supply chain management and logistics architectures. The software models interplanetary space logistics as a network, allowing the user to input scenarios, simulate them, and generate measures of effectiveness. Optimization can be used to find the best logistics
