*********************************
There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract
As low-cost rocket launch technologies and space resource utilization systems emerge, human space exploration is attracting increasing interest from industry, government, and academia. To extend the domain of human activity beyond the low-Earth orbit and maintain a long-term human presence in cislunar space and eventually Mars, there are three fundamental questions to answer regarding space logistics:
These questions relate to broad fields in space system engineering, including space vehicle design, space transportation, space resource utilization, and related supporting technologies. A series of interdisciplinary design and optimization frameworks and tools are critical to performing large-scale space mission planning, optimizing spacecraft and space infrastructure designs, and stimulating space commercialization. The objective of this research is to fulfill the demands of human space exploration by developing integrated space logistics frameworks, focusing on space vehicle design, space transportation scheduling, space infrastructure design, and space commercialization by leveraging state-of-the-art in space logistics and space system engineering.
These frameworks are developed based on a network-based space logistics optimization model, which considers the space mission planning problem as a multi-commodity network flow problem. The network-based space logistics approach is a common and fundamental model for the proposed frameworks. However, depending on the specific application and the problem, they investigate different perspectives of space logistics and focus on resolving different challenges. For space vehicle design, a piecewise linear approximation method is proposed to consider nonlinear spacecraft design models. For large-scale space transportation scheduling, a partially periodic time expended network is introduced leveraging the repeating nature of regular transportation missions. For space infrastructure design, a new space infrastructure design concept is developed that considers infrastructure subsystems’ internal interactions and their external synergistic effects with space logistics simultaneously. For space commercialization, space mission planning optimization is considered under a multi-player decision-making environment.
