Logistics Systems (L)¶

Summary. Packaging, handling, staging and transferring the equipment, supplies and consumables a mission needs, plus trash and waste management, "including meeting planetary protection requirements" (ADD Rev C, p. 43). Logistics starts with what arrives with the crew and grows toward longer, Mars-length missions. Its one Rev C element is the Gateway Logistics Element. Seven technology gaps list it, four named in the Moon Base Users Guide (near-term). Decomposition letter: L.

NASA's description¶

"This sub-architecture includes systems and capabilities needed for packaging, handling, staging, and transferring logistics items. These items include equipment, materials, supplies, and consumables needed to meet functional needs. The sub-architecture also includes approaches and capabilities for addressing trash and waste management (including meeting planetary protection requirements).

Initially, logistics items and consumables are limited to those that arrive with crew. As time advances, the architecture introduces additional capabilities that fulfill broadening logistics needs, including supporting longer durations (e.g., for Mars missions). As the sub-architecture matures, it takes advantage of increased automation and/or in-situ sourcing of logistics resources.

The amount and types of logistics items needed, along with their interfaces with surface elements, drive the type and quantity of the logistics carriers needed. Carrier types could include those suitable for EVA transfer (e.g., carriable through a hatch or an airlock)." (ADD Rev C, p. 43)

In the segments¶

From ADD Rev C, Foundational Exploration unless marked:

The "Pressurized Mobility" reference mission includes "logistics and waste management", and added habitation, mobility, crew and sites "will create additional needs for logistics transport and stowage, trash disposal, maintenance, and other infrastructure services and support" (p. 29).
"Robotic Uncrewed Operations" includes "logistics transfers" (p. 29). "Extended Surface Habitation Operations" needs "interfaces for logistics transfers (e.g., for solid and fluid consumables, maintenance, utilization, and waste)" (p. 30).
Areas of future work: "Incorporating waste management approaches and element repurposing, recycling, and disposal for extended durations" (p. 32).
Sustained Lunar Evolution. "The addition of expanded power, logistics, and ISRU capabilities would enable more missions" (p. 34); "logistics" heads the list of areas for expanded demand signals (p. 36).
Humans to Mars systems "will represent transportation, logistics, utilization, and more" (p. 23).

Elements¶

Element	Segments	Source
Gateway Logistics Element (part of Gateway, ADD Section 2.3.4.1.4)	Human Lunar Return, Foundational Exploration	ADD Rev C, pp. 26, 31

See the elements index. It is a cargo service to Gateway in lunar orbit, not to the surface: "NASA anticipates at least one logistics services delivery for each Gateway mission of 30 days", and the Gateway Logistics Services contract is "extensible to … other destinations beyond Gateway" (p. 52). For Gateway's status since Rev C, see Gateway.

The 2025 Architecture Update¶

The companion 2025 Architecture Update treats logistics as one of three lunar "services … akin to the utilities that serve communities on Earth", with power and C&PNT (p. 9):

"Logistics encompass the many supplies that long-duration exploration requires. Logistics services deliver food, water, clothing, gases, utilization equipment, spare parts, and other essentials to the lunar surface and move them to where they will be needed. NASA is encouraging the development of commercial lunar logistics services with its Commercial Lunar Payload Services (CLPS) program, which currently delivers utilization payloads from NASA and other customers to the lunar surface aboard commercially managed missions. As exploration evolves, commercial providers will be able to deliver additional supplies in larger amounts, as well as large pieces of lunar infrastructure." (Update, p. 9)

Here the Update ties logistics to CLPS, a Transportation Systems element in the ADD. For more, it points to the "Lunar Surface Cargo" and "Lunar Logistics and Mobility" white papers (2024). The first is read on Transportation Systems: it forecast "2,500 to 10,000 kg per year for annual recurring logistics" and some larger elements in Foundational Exploration (Lunar Surface Cargo, p. 2). No paper titled "Lunar Logistics and Mobility" is among the sources; the nearest is the 2024 mobility paper, on Mobility Systems (open question 30). In August 2024 NASA had named "an integrated surface logistics architecture" one of "two gaps in its lunar architecture" (the other uncrewed surface mobility) and sought industry studies of it under NextSTEP-2 Appendix R, in seven areas from logistics carriers to trash management; nine companies won $24 million of study contracts in January 2025 (RT-2; Appendix R page, "Solicitation Overview"; "Study Contracts Awarded"). "Lunar logistics capabilities" is the first of the Update's three focus areas for 2026 (p. 18). The new Lunar Utility Rover, a Mobility Systems element, is mapped to "Interface robotic system(s) with logistics carriers on the lunar surface" (FN-A-105 L; p. 5).

In the February 2024 workshop briefing¶

Older than Rev B and Rev C, the February 2024 workshops briefed the 2023 paper "Lunar Logistics Drivers and Needs" (not held) (logistics briefing). Logistics items are "Items needed to sustain life, maintain systems, and allow for productive science and utilization activities" (slide 2), and "everything not initially delivered as part of a vehicle or element dry mass needed to support missions" (slide 8).

Six categories (slide 3): consumables; utilization (payloads and research); maintenance items; outfitting; spares; packaging, overhead and carriers, each defined on the source page.
Four drivers (slides 5, 8): "Crew size, mission duration, ECLSS sub-architecture capabilities, and planned EVA cadence are the primary drivers for the total logistics needs."
How much (slide 6): total logistics for 2 and 4 crew over 7 to 28 days on the surface, "Does not include pressurized carriers or tank mass"; read off the chart, from about 500 kg (2 crew, 7 days) to about 2,000 to 3,000 kg (4 crew, 28 days) (the wiki's approximate reading).
What it is made of (slide 7): for "a conceptual Open-loop ECLSS lunar surface mission with a significant planned cadence of EVAs", water 29%, EVA 21%, food 14%, oxygen 9%, consumables 8%, spares 7%, nitrogen 7%, utilization 5% (matched to the legend by the wiki; the paper's Figure 2 shows the same, as far as a thumbnail can be read). "Water, gases, and food dominate overall logistics needs by mass" (slide 8).
"The process for estimating logistics item needs for conceptual missions does not dictate requirements for future missions" (slide 4).

What changed by Rev C (the wiki's comparison): the chart's crews and stays sit within Rev C's legacy decisions (up to four crew, up to 33 days; Key definition tasks); Rev C prints no logistics masses of this kind. The briefing's title is the 2023 paper's, not the Update's "Lunar Logistics and Mobility" (open question 30).

Moon Base Phase 1¶

The Users Guide's "Logistics systems" group: "Systems and capabilities related to the packaging, handling, transportation, staging, storage, tracking, and transfer of items and cargo for the Moon Base" (Users Guide, p. 9). Four FN-L functional gaps: mating pressurized assets, and transferring pressurized cargo, water and gases into habitable assets. A fifth FN-L function, FN-L-301 L (waste management), sits in the guide's Habitation group. Capability target: "Demonstration of capabilities to transfer pressurized goods, water, and gases on the lunar surface." Logistics strategies are also one of the guide's Mars-forward areas (Mars-forward). Full list: Phase 1 functional gaps.
