Lunar Surface Cargo (ACR24 white paper)

Document: Lunar Surface Cargo, a six-page white paper headed "2024 Moon to Mars Architecture" and footed "2024 Moon to Mars Architecture Concept Review". No date is printed beyond the year; the download path is 2024/06. Files: text sources/text/docs/2024-06-acr24-lunar-surface-cargo.txt; raw sources/raw/docs/2024-06-acr24-lunar-surface-cargo.pdf (fetched 2026-10-01T07:22:46Z from https://www.nasa.gov/wp-content/uploads/2024/06/acr24-lunar-surface-cargo.pdf, per sources/manifest.csv). Page numbers: the printed numbers (1–6) match the PDF pages and the text file's [page N] markers. All six pages were checked against the PDF.

Which paper this is. NASA's White Papers web page lists it under "2024 Architecture Concept Review": "Analyzes projected needs and capability gaps for transportation of cargo to the lunar surface" (White Papers page, fetched 2026-10-01). It was published "concurrently" with Lunar Mobility Drivers and Needs (p. 2). It cites ADD Revision A and says a cargo reference mission "will be added to the ADD in revision B" (p. 1), so it was written before Rev B (Dec 2024). It is 2024 context, not the current architecture.

Summary. NASA set a sample of planned and potential surface cargo against the landers it had, and found "a gap in cargo lander delivery … between 500 kg and 12,000 kg, for which significant demand exists" (p. 3). Demand is forecast at 2,500 to 10,000 kg a year in Foundational Exploration, with single items up to 15,000 kg (p. 2). The paper's answer is a "mixed cargo lander fleet" from industry and international partners, for "dissimilar redundancy" (p. 3). Its content is on Transportation Systems.

What the PDF shows that the text layer loses

• Figure 1 (p. 2), "Planned and potential cargo to the lunar surface." Titled "lunar surface cargo needs". A mass axis from 500 to 16,000 kg, banded "Small", "Mid-Size" and "Large", under a banner reading "Human Lunar Return", "Foundational Exploration" and "Sustained Lunar Evolution" from left to right. The text explains: "each item is represented by a potential mass range and its notional alignment within an exploration campaign segment defined in the ADD" (p. 2). Items, as labeled: "Lunar Terrain Vehicle", "Vertical Solar Array Technologies", "Lunar Surface Relay - Mobile", "IP Mobility System", "Endurance Rover", "Sample Return Freezer", "Fission Surface Power", "Pressurized Rover", "Initial Surface Habitation", "Surface Habitats", "Logistics for 2 Crew with Pressurized Rover" and "Logistics for 4 Crew with Pressurized Rover and Habitat" (each at 7, 14, 21 and 28 days), "In-Situ Resource Utilization Pilot Plant" and "logistics". The bars for the Pressurized Rover, Initial Surface Habitation and Surface Habitats reach the "Large" band. Its note: "While contracts are in place for some cargo identified, this figure does not represent agency decisions to fly any item, nor does it reflect the order of flights for any of the items represented." "IP" is not expanded. The wiki reads no bar values off the chart.
• Figure 2 (p. 3), "Planned lander capability compared with lunar surface cargo demand." The same chart with three labeled boxes: "HDL Lander Capability" across the top of the "Large" band, "Current CLPS Task Order Capability" along the bottom, and "Demand Gap Opportunity" between them. The text gives the gap as 500 to 12,000 kg (p. 3).
• Figure 3 (p. 4), "Relative scale of potential landing regions and the Washington, D.C., area." Printed sideways. Eight labeled regions laid over a map of the Washington–Baltimore area: "De Gerlache Rim 2", "De Gerlache Rim 1", "Connecting Ridge Extension", "Connecting Ridge", "Haworth", "Malapert Massif", "Peak Near Shackleton" and "Faustini Rim A". The text calls them "potential landing and exploration regions" in "the lunar South Pole region" (p. 3).

• Table 1 (p. 3), "Planned and Potential Cargo Landers":

  Lander type	Mass delivery capability (kg)	Provider
  CLPS – Current Task Orders	70 – 475	U.S.
  HDL Cargo Lander	0 – 12,000 or 15,000	U.S.
  ESA Argonaut Lander*	Up to 2,100	International
  JAXA Cargo Lander Capability	Under Study	International

  "*Note: Delivered mass represents cargo platform element + payload." The text layer splits the table into single cells.

• Emphasis. Two sentences on p. 2 are bold in the PDF: "NASA forecasts a cargo demand range of 2,500 to 10,000 kg per year", and "These cargo deliveries are necessary to meet a variety of exploration, science, and technology development objectives and a robust future cargo delivery demand drives considerable cargo lander capability needs."

Key takeaways (p. 6)

• "Foundational Exploration and Sustained Lunar Exploration segment goals require significant transportation of cargo to the lunar surface."
• "HDL is the only lander currently expressed in the architecture that can deliver beyond 500 kg to the lunar surface."
• "NASA anticipates an aggregate demand for lunar surface cargo on the order of 2,000 to 10,000 kg per year."
• "To mitigate this capability gap, strategic considerations include engaging multiple providers across both international partners and industry over time, offering dissimilar redundancy."
• "Communication of cargo demand to the exploration community helps enable industry and international engagement."

What changed by Rev C

These comparisons are the wiki's. The paper predates Revisions B and C.

• A reference mission, then an element. The paper says "NASA has developed a conceptual reference mission for cargo lander delivery that will be added to the ADD in revision B" (p. 1). ADD Rev C's revision history says Revision B "Added the following elements and their functional mappings: initial surface habitat and lunar surface cargo lander" (ADD Rev C, p. 3). Rev C's seven Foundational Exploration reference missions include none for cargo delivery (Foundational Exploration). The paper's mission wording is close to Rev C's one-pagers. The paper's lander "Provides all services necessary to maintain cargo from in-space transit through landing on the lunar surface until the cargo is either offloaded from the lander or in an operational state" (p. 1). The Lunar Surface Cargo Lander "provides all the services necessary to maintain its cargo from launch vehicle integration through landing on the lunar surface and until cargo offloading or independent operations" (ADD Rev C, p. 59). The wiki doesn't say the reference mission became that element (open question 45).
• No mass for the new lander. Rev C gives the Lunar Surface Cargo Lander "moderate amounts of cargo" and no figure (p. 59). The paper's 500–12,000 kg gap is not a specification for it, and the wiki doesn't size the element from it.
• Capacities in Table 1 are not in Rev C. Rev C's HDL and CLPS one-pagers give no mass (HDL; CLPS). Rev C doesn't mention Argonaut (search of the text).
• Cargo return. The paper says "the capacity needed to achieve stated objectives greatly exceeds the return capability offered by existing elements" (p. 3). One of Rev C's ten Foundational Exploration areas of future work is "Increasing cargo mass delivered to and returned from the lunar surface" (ADD Rev C, p. 32).
• Gateway Logistics Element. The paper leaves Gateway deliveries out, pointing to "Table 3-6 of ADD Revision A" for its functions (p. 1). Rev C still lists the element (Gateway).

Cited by a later paper

The 2025 white paper "Why Moon and Mars?" cites this paper (its reference 31) for: "NASA projects annual logistics needs of 5,000 to 6,000 kgs for four crew members operating on the lunar surface for approximately 30 days" (Why Moon and Mars?, p. 5). This paper's text doesn't contain that figure (search of the text). Its demand figures are 2,500 to 10,000 kg a year (p. 2) and 2,000 to 10,000 kg a year (p. 6), and its Figure 1 plots "Logistics for 4 Crew" by duration with no printed values. The nearest wording is in the companion mobility paper: "four crew members operating on the lunar surface for approximately 30 days", with logistics of "2,000 to 6,000 kg per crewed surface mission" (Lunar Mobility Drivers and Needs, PDF p. 3). The wiki doesn't decide where the 5,000–6,000 kg comes from (open question 45). The 2025 Architecture Update also points to this paper, on lunar logistics (Update, p. 9).

References that are other architecture documents

The paper cites nine references (p. 6). As printed:

Ref.	Title, as printed	Among the wiki's sources?
1	ESDMD-001 Rev. A, Moon to Mars Architecture Definition Document (ADD)	no; the wiki's ADD is Rev C
2	Lunar Logistics Drivers and Needs, 2023 Moon to Mars Architecture White Paper	no
3	Lunar Mobility Drivers and Needs, 2024 Moon to Mars Architecture White Paper	yes, source page

The others are NASA's CLPS, HLS and HDL web pages, ESA's Argonaut page, a JAXA briefing at the 2024 Humans to Mars Summit, and "International Space Station Lessons Learned for Space Exploration, September 2014". "No" means no file in sources/manifest.csv or sources/text/pages/ has a matching name.

Oddities

Recorded as printed, PDF checked (open question 45):

• Two demand figures. "2,500 to 10,000 kg per year" in the body (p. 2) and "2,000 to 10,000 kg per year" in the takeaways (p. 6).
• Swapped reference numbers. The text cites the mobility paper as [2] and the logistics paper as [3] (p. 2), but the list has 2 = "Lunar Logistics Drivers and Needs" and 3 = "Lunar Mobility Drivers and Needs" (p. 6). The quotation "food, water, air, spare parts, and other similar products …" is footnoted [3], the mobility paper by the list.
• Two links for the logistics paper. Reference 2 here links a compiled volume, acr23-white-papers-compiled-v10.pdf. The mobility paper links the same title as lunar-logistics-drivers-and-needs.pdf.
• "Sustained Lunar Exploration" in the first takeaway (p. 6). The banner on Figures 1 and 2 reads "Sustained Lunar Evolution", the ADD's segment name. Two of the ADD's own gap tables make the same slip (open question 21).
• Promised papers. The paper promises an ACR24 paper on cargo return "later this year" (p. 3) and "white papers on NASA's lunar surface strategy and cargo return needs" (p. 5). NASA's White Papers page lists neither title.
• As printed: "Services may be needed from landing to until the cargo is fully operational" and "a landers' vicinity" (p. 1).
