Item Advancements in Logistics Reduction for Exploration Missions(2023 International Conference on Environmental Systems, 2023-07-16) McKinley, Melissa; Ewert, Michael; Borrego, Melissa; Orndoff, Evelyn; Fink, Patrick; Sepka, Steven; Richardson, Justine; Hill, CurtisManagement of logistics on exploration missions includes both looking for ways to minimize the quantities, mass and volume of various consumables, supplies, spares and equipment as well as ways to minimize the crew time needed for locating and handling those items. Also included are ways to minimize the waste, handling and resultant products from the processes of maintaining a crew on these missions. The Logistics Reduction project encompasses technologies for management of waste, trash, autonomous logistics, and clothing. This paper provides a status of work in these areas including recent accomplishments and challenges encountered. Future objectives will also be covered along with the work currently in progress. Specifically, the paper will cover technologies in waste management, namely, the Universal Waste Management System (UWMS) or exploration toilet and work on an alternative waste collection container, the Alternate Fecal Canister. Trash management technologies work on the Trash Compaction and Processing System (TCPS) and Trash to Gas (TtG) is summarized with progress to date as well as information on how Jettison as an option is related. Progress and summary of recent accomplishment on the RFID (Radio Frequency ID) Enabled Autonomous Logistics Management (REALM) and the Autonomous Logistics (AL) technologies is detailed. Advanced Clothing System (ACS) and work in the area of Systems Engineering and Integration (SE&I) is also included. Status of the technologies, accomplishments and how the focus areas inform program decisions will be addressed.Item Development Status of Logistics Reduction Technologies for Exploration Missions(2020 International Conference on Environmental Systems, 2020-07-31) Broyan, James; Ewert, Michael; McKinley, Melissa; Fink, Patrick; Badger, Julia; Lee, JeffreyTechnologies that reduce logistical mass, volume, and the crew time dedicated to logistics management are important for both lunar focused Artemis missions and future Mars transit missions. NASA’s Advanced Exploration Systems’ Logistics Reduction project is developing technologies that can benefit a wide range of exploration missions. Logistics reduction technologies include improvements to compact toilets for efficient waste collection and trash compaction with stabilization which will maintain hygienic habitable volumes as consumables are converted to waste products. Gateway and Artemis missions will both consist of periodic crewed periods separated by substantial periods of dormancy. Assembly of a Mars transit vehicle also consist of periodic crewed and longer uncrewed mission phases. Radio Frequency Identification (RFID) autonomous tracking and localization will relieve the crew of inventory management duties, especially important during the time critical crew periods, and ensure the correct items are transferred between visiting elements, especially those destined for disposal. Inventory tracking combined with the ability to robotically manipulate cargo enables beneficial scenarios of configuring exploration habitats before the crew arrives, or after they depart, thereby allowing increased focus on science and other mission objectives. Robotic cargo manipulation is also extensible to wider habitat maintenance applications. This paper provides a status of the technologies being developed, maps them to exploration mission technology gaps and enhancements, and explains where they will be validated.Item Logistics Reduction Advancements and Future Plans for NASA’s Exploration Missions(2024 International Conference on Environmnetal Systems, 2024-07-21) McKinley, Melissa K.; Ewert, Michael K.; Borrego, Melissa A.; Fink, Patrick; Sepka, Steven; Richardson, Tra-My Justine; Pitts, Ray; Meier,Anne; Hill,CurtisManagement of logistics on exploration missions includes both looking for ways to minimize the quantities, mass and volume of various consumables, supplies, spares, and equipment as well as ways to minimize the crew time needed for locating and handling those items.

The Logistics Reduction project encompasses technologies for management of waste, trash, autonomous logistics, and clothing. This paper provides a status of work from 2023 in these areas including recent accomplishments and challenges encountered. Future objectives and plans for 2024 will also be covered along with the work currently in progress.
