Overview: NASA's Moon to Mars Architecture

Summary. The Moon to Mars Architecture is NASA's framework for turning its long-term exploration objectives into the systems needed to meet them. NASA works backwards from ten goals to use cases, functions and elements, then lists what is still missing: functions no element performs, technology gaps, data gaps and open definition tasks. The current baseline is the Architecture Definition Document (ADD) Rev C (December 2025) with its gap and decomposition spreadsheets. The Moon Base, announced in March 2026, attaches to it through the April 2026 Moon Base Users Guide. The guide picks out 31 functional gaps for Phase 1, and names 19 tech gaps and the 19 lunar data gaps as challenges for "near-term Moon Base development" (the wiki's label: "named in the Moon Base Users Guide (near-term)"). Each section below links to the page that holds the detail.

What the architecture is

  • NASA's definition. "The architecture offers a high-level, unifying structure for the Moon to Mars endeavor. It provides rules, guidelines, and constraints that define a cohesive and coherent framework" (ADD Rev C, p. 9). The document "establishes the process of objective decomposition, outlines the architecture's constituent parts, and provides insight into the ongoing evolution of the architecture" (p. 9). See Architecture framework.
  • What it is not. "This is not a manifest or requirements document. Rather, it is a tool for those seeking to understand or engage with the architecture" (p. 9). It also says it is not "procurement direction", "a budget request" or "a policy document": "Architecture products communicate needs; they do not presuppose solutions" (p. 13).
  • What it reflects. "the approved baseline for programs of record, contracts, partnerships, and funding". Changes appear "after formal approval of and adoption by the U.S. government" (p. 9). So plans announced in 2026 are not yet in it (below).
  • How often it changes. NASA updates the ADD once a year, after its Architecture Concept Review (ACR; ACR24 and ACR25 name the 2024 and 2025 reviews). Rev C was released 12/12/2025, after the initial release (April 2023), Rev A (January 2024) and Rev B (December 2024) (pp. 3–4, 9). See Architecture definition process and the ADD source page.

The current documents.

The 2022–2024 documents are context. They are the objectives, the 2023 strategy document, two executive overviews, and the ACR24 white papers and mapping tables. All are listed on the index.

Two more groups of source are newer than Rev C, or speak alongside it:

  • The Moon Base and Ignition material (March–September 2026). "Ignition" is the name of NASA's event of 24 March 2026, at which it announced the Moon Base and its other new initiatives. The Ignition page links the event's release, six fact sheets dated 24 March 2026, and six presentation decks: five listed on 26 March 2026 and a "NASA Inspires" recap with no date (dates as the page prints them). With them come NASA's Moon Base web pages and releases to September 2026. They record the plans announced since Rev C (below).
  • The workshop slides (February 2024 to February 2026). NASA's briefings to industry, academia and international partners, with eight partner posters from Rome. They are briefings, not the architecture of record, and rank below Rev C (below).

How it is built: from objectives to elements

NASA calls the method "architect from the right and execute from the left": "beginning with long-term goals (farthest to the right on a timeline) and working backwards to establish the capabilities required to achieve them" (ADD Rev C, p. 13). See Objective decomposition.

Layer What the sources hold Wiki pages
Goals and objectives Ten goals and 63 objectives, each marked lunar (L), Martian (M) or both (LM), set in September 2022 (Moon to Mars Objectives). Rev C's goals and the December 2025 lunar workbook print the same wording. Objectives: the ten goals; Lunar objectives; Mars objectives
Characteristics and needs The layer between objectives and use cases. Only NASA's 2024 mapping tables print it: 133 lunar, 115 Mars (lunar and Mars tables) Lunar and Mars characteristics and needs
Use cases and functions 163 lunar use cases and 208 lunar functions; 148 Mars use cases and 263 Mars functions (ADD Rev C, Appendix B.2, pp. 110–147). IDs such as FN-P-101 L are what gaps and the Moon Base guide cite. Use cases and functions and the four list pages
Elements 15 elements, the "major systems and hardware that enable exploration". The ADD "only includes funded elements that the agency has formally committed to developing" (p. 45). Appendix B.3 maps each one's lunar functions. Elements and one page per element
Recurring tenets Nine cross-cutting principles, from international collaboration to commerce; "The ordering of recurring tenets does not imply prioritization" (p. 84) Recurring tenets

The framework: segments and sub-architectures

Segments. The architecture is split into four segments, "broad phases of exploration" (ADD Rev C, pp. 21–23). "Although these segments appear in sequential order, they are not exclusively serialized … NASA pursues parallel development of architecture segment capabilities" (p. 22).

Segment NASA's tagline (pp. 22–23) Elements mapped Tech gaps listing it Data gaps listing it
Human Lunar Return "Initial capabilities necessary to re-establish human presence on and around the Moon." 8, plus the Gateway Logistics Element none: its technology is funded by "the current programs" (p. 79) 17
Foundational Exploration "Expansion of lunar capabilities supporting complex orbital, surface, and Mars precursor missions." all 15, plus the Gateway Logistics Element 32 2
Sustained Lunar Evolution "Growing capabilities to enable economic opportunity, global access, and regular human presence." none yet. "This segment is an open canvas" (p. 33). 46 0
Humans to Mars "Initial capabilities necessary to establish a human presence on Mars." none yet: "forward work" (p. 38) 44, 11 of them listing only this segment 6

Gap counts are from the segment columns of the tech gaps and data gaps spreadsheets. A gap can list more than one segment (Segments).

Sub-architectures. There are 12, "tightly coupled elements, functions, and capabilities that perform together", each with a letter used in function IDs (pp. 18, 40). Elements fall in only seven of them. Autonomous Systems and Robotics, Data Systems and Management, Human Systems, In-Situ Resource Utilization (ISRU) and Utilization have none (Sub-architectures; Elements).

What the architecture says it still needs

The ADD publishes four kinds of need. NASA calls the gap lists a "demand signal" to industry, academia and partners (ADD Rev C, pp. 78, 80–81).

  1. Functions no element performs. Appendix B.5 lists them by use case (pp. 167–184). For Foundational Exploration that is 77 functions. Among them are all 15 ISRU functions, propellant storage and surface transfer, power and positioning, navigation and timing (PNT) away from the South Pole, and month-plus habitation. For Human Lunar Return it is one, the lunar time scale. See Lunar function allocation and Foundational Exploration. Mars functions have no element mapping yet.

  2. Technology gaps: 57, ranked. A gap is where new technology is needed. "If a new project or program can meet an architectural need using existing technology, then that area is not a technology gap" (Users Guide, p. 11). NASA ranks them 1 to 57 in six bins on four weighted metrics: criticality, urgency, breadth and depth. Cost is left out (ADD pp. 77–78). The first list, with 56 gaps, came with Rev B (2024 technology gaps white paper, pp. 1, 4). Rev C added #0504 and #0505 and turned #0602 into five data gaps (2025 Architecture Update, p. 14). The top six:

    See the gaps index and the tech gaps spreadsheet.

    #1107 rose the most at the top. Rev B ranked cryogenic fluid transfer 11th, in bin 2; Rev C rates it 4th, in bin 1. It is one of three gaps that moved up a bin between the two lists, and none moved down. The comparison is the wiki's, between Rev B's list as printed in a February 2025 workshop briefing and the Rev C spreadsheet (technology gaps briefing, slide 5; gaps index).

  3. Data gaps: 25, unranked. They are new in Rev C: 19 lunar and 6 Mars. "While the current data gaps are not listed in priority order, they all represent near-term, high-priority needs", and "even partially addressing the defined data gap is valuable to the architecture" (ADD p. 81). Most ask for measurements on the surface. See the data gaps index.

  4. Open definition tasks. These are questions the architecture must settle before it can be designed further. Appendix C's table holds 71 key definition tasks, 67 of them open, all Mars or destination-neutral (pp. 194–197). See Key definition tasks.

Decisions already taken (pp. 74–76):

  • Seven legacy decisions, among them:
    • the South Pole as the initial crewed landing region
    • Gateway in lunar orbit, and a near rectilinear halo orbit (NRHO) for crewed lunar orbital operations
    • up to four crew per integrated mission
    • surface stays of up to 33 days
  • Seven completed key definition tasks:
    • lunar power augmentation trades, a hybrid lunar logistics strategy, and "Space-to-Space Communications Systems, WiFi 6, and 3GPP (5G)" for lunar surface communications
    • fission as the primary Mars surface power (2024)
    • a down-select of the first Mars target state, a Mars loss-of-crew risk method, and at least four crew to the Mars surface (2025)

Several of the lunar decisions are touched by the 2026 changes below.

The Moon Base

NASA announced the Moon Base on 24 March 2026: "the United States would establish a Moon Base in the lunar South Pole region, using a phased iterative approach". Its end goal is "a continuous human presence on the lunar surface" (Users Guide, pp. 2–3). There are three phases:

  • Phase 1, Now–2029: access, experiment, learn
  • Phase 2, 2029–2032: build and expand
  • Phase 3, 2032 and beyond: live and work on the Moon

(Moon Base Phases). The Users Guide links the Moon Base to the ADD through three resources: unallocated functions, technology gaps and data gaps (p. 3).

What the sources say the Moon Base needs (Needs, by phase):

  • Phase 1 in detail. 31 ADD functions, in seven groups with capability targets, "must close to enable the first phase" (pp. 8–10).
    • Seven have no element in the ADD's Foundational Exploration tables: month-plus habitation and countermeasures, waste, water and gas transfer, resource identification, and one power function (the wiki's join).
    • The tech-gap sheet's own traceability ties 17 gaps to these functions. The guide's challenges cite only 4 of the 17 (tech gaps spreadsheet; Users Guide, pp. 12–13).
  • Tech and data gaps: near-term work for later phases. The guide names 19 tech gaps and all 19 lunar data gaps, labeled on the wiki "named in the Moon Base Users Guide (near-term)". It calls them challenges "associated with near-term Moon Base development efforts", with Phase 1 missions maturing technologies "to enable essential phase two and phase three capabilities" (p. 11).
  • Flight tests in Phase 1. "Technology readiness" is one of the two "key strategic factors" the guide gives for the phased approach, beside market enablers. In Phase 1 it looks to flights on Commercial Lunar Payload Services (CLPS) landers: "While many Moon Base–enabling technologies already exist on Earth, NASA must mature these capabilities through flight test missions. Near-term flights aboard CLPS landers and other commercial missions during phase one will prove these technologies in space and create opportunities for iteration and advancement, all while buying down risk for subsequent Moon Base phases" (Users Guide, p. 6; Phases; Priorities).

  • Phase 1 missions on the same subjects as data gaps (the wiki's matching). NASA's phases page says what four Phase 1 missions will measure (Moon Base Phases):

    • the Stereo Cameras for Lunar Plume-Surface Studies (SCALPSS) on Blue Moon MK1 will study "how rocket engine plumes interact with the lunar surface": plume effects, DN-017 L and DN-018 L
    • the Lunar Dust Level Sensor and Effects on Surfaces (LDES) on Griffin-1 and IM-3 will "measure how lunar dust accumulates on spacecraft and surface systems": DN-019 L
    • the Volatiles Investigating Polar Exploration Rover (VIPER) will sample soil "at different depths and temperatures, searching for water ice and other volatiles": DN-007 L and DN-013 L
    • the MoonFall hoppers will create "terrain maps of potential landing sites" and "measure radiation levels": DN-002 L, DN-012 L and DN-007 L

    No source says these missions address these data gaps. The only link a source makes is DN-017 L's own row, which names SCALPSS for an earlier flight on Blue Ghost. Most fits are partial: one lander type at one site, where the plume gaps ask for "different sites" and "different plume conditions (i.e. lander types)"; dust accumulation, where DN-019 L also asks for particle charge. The table, with the fit of each, and the later CLPS payloads (four landings in late 2028, three PRISM suites) are on the data gaps index.

  • Phases 2 and 3. The guide gives goals only, for example:

    • CLPS payloads of 5 and then 8 metric tons
    • regolith manipulation and site preparation
    • uncrewed cargo return
    • "Continuous Crew Presence"

    (p. 4). The Ignition material lists what each phase brings: "improved solar and initial nuclear-based power stations" and "surface-to-orbit communications stations" in Phase 2, "An operational fission surface power station" and "Operating pressurized rovers" in Phase 3 (Building the Moon Base fact sheet, p. 1). The Moon Base Program's Ignition deck adds capability items by phase, from surface "cell towers" to "Initial surface habitats > 100 m³" (Ignition deck 2, slides 41–62). NASA's undated Moon Base Systems page takes five systems (mobility; communications and PNT; habitation; power; logistics) through the phases in much the same terms as the deck, with figures for the Phase One lunar terrain vehicles and the Phase Two pressurized rover, and with no ISRU area (Moon Base Systems; the wiki's comparison with the deck is on Phases). None of them cites a function or gap ID. Some name systems:

    • Named by the sources: CLPS, in the guide's Phase 2 and 3 goals (p. 4); and "cargo‑capable human landing systems (HLS)" in Phase Three (Ignition release, "Building the Moon Base").
    • Matched by the wiki, by name: the deck's Lunar Terrain Vehicles (LTVs) in Phase 1 (slide 11), its "Human Landing System" label on the Phase 1 render (slide 10) and JAXA's pressurized rover in Phase 2 (slides 20–22), read as the ADD's Lunar Terrain Vehicle, Human Landing System and Pressurized Rover.

    See Needs, by phase and Phases.

The Moon Base pages (hub) cover the phases, priorities, Phase 1 functional gaps, technology and knowledge challenges, site environment, missions and assets, surface technology and Mars-forward areas. Rev C's legacy decision for the South Pole region, and what the 2023 "Lunar Site Selection" paper says about choosing a site, are on Lunar site selection. No source maps ADD segments to Moon Base phases.

Mars

The Humans to Mars segment is decomposed but not designed.

  • The decomposition is done. 46 objectives, 148 use cases and 263 functions (Mars decomposition).
  • Missions and elements are not. "Mapping of elements to use cases and functions for the Humans to Mars segment is forward work" (ADD Rev C, p. 38).
  • What is decided. Fission for surface power (MD-07, p. 75), and "no fewer than four (4) crew to the surface" (MD-05, p. 76).
  • The target state. It is narrowed to three options, all with several crewed surface missions (MD-02, p. 193).
  • The gaps. Eleven tech gaps are Mars-only, by their performance targets (tech gaps spreadsheet; gaps index). The six Mars data gaps are not tied to the Moon Base (data gaps spreadsheet; Users Guide, pp. 12–13).

The Users Guide treats the Moon Base as a Mars proving ground in seven areas, among them nuclear technologies, Earth-independent operations, dust tolerance and planetary protection (Users Guide, p. 14; Mars-forward). See also Key definition tasks, Planetary protection and the Mars use-case and function pages.

What has changed since Rev C

Rev C describes the architecture as of December 2025. Since then:

  • Artemis is resequenced. Artemis III becomes a "Human landing system & EVA suit test mission in Earth orbit" (2027). Astronauts return to the surface on Artemis IV, early 2028 (Going back to the Moon, p. 2). The plan also "standardizes the SLS upper stage and mobile launcher configuration" (p. 1).
  • Artemis II has flown, in April 2026 (Users Guide, p. 11, photo caption).
  • The Moon Base was announced on 24 March 2026, with NASA's "Ignition" initiatives (Ignition release; Ignition page).
  • NASA reorganized in May 2026. Rev C is a publication of the Exploration Systems Development Mission Directorate (ESDMD). The realignment unifies ESDMD and the Space Operations Mission Directorate as the Human Spaceflight Mission Directorate (HSMD), and merges aeronautics and space technology into a Research and Technology Mission Directorate (RTMD) (realignment release, 22 May 2026). HSMD's divisions are Low Earth Orbit, Moon Base, and "Artemis … (renamed from Moon to Mars)". The Moon Base Program takes "all lunar programs outside of the Artemis program", among them CLPS, and is to "Develop an integrated lunar architecture and operations plan". Space nuclear work, under a Space Reactor Office, and Space Communications and Navigation (SCaN) go to RTMD, though Directive 6 gives the Moon Base Program authority "across all lunar missions, including SCaN" (Administrator's workforce note, 22 May 2026, Directives 6 and 7). The Moon Base Program Manager, Carlos García-Galán, said in August that after the post-Ignition request for information "our architecture team is evaluating what's needed, matching up to technology gaps", as reported (Moon Base podcast). None of these sources mentions the ADD, its Strategy and Architecture Office or the Architecture Concept Review, and none relates the program's plan to the ADD. The wiki records that as silence (Architecture definition process).
  • Gateway is paused. "the agency intends to pause Gateway in its current form and shift focus to infrastructure that enables sustained surface operations" (Ignition release). Its Power and Propulsion Element becomes the bus of Space Reactor-1 (SR-1) Freedom (the name as its mission page gives it), a nuclear electric propulsion demonstration to launch to Mars in December 2028 (Users Guide, p. 2; nuclear power fact sheet, pp. 1–2). Hardware of Gateway's Habitation and Logistics Outpost (HALO) is reused for Moon Base surface demonstrations (Moon Base update, Aug 2026). Briefed at Ignition, the current Gateway architecture is "not required to accomplish the primary objectives of landing humans on the Moon and establishing a Moon Base" (Ignition deck 2, slide 2). NASA's undated Artemis page still calls Gateway "central"; the wiki follows the dated release (Gateway; open question 79).
  • The phases have figures, money and several names. The Moon Base Program's Ignition deck prints the guide's launch, landing and mass figures with per-year tables. Read with the wiki's sums of the printed counts, the tables show the figures are per phase: Phases 2 and 3 sum to their figures, and Phase 1 to its 21 landings. One count doesn't fit: Phase 1's launches sum to 24 on the table (slide 17), where the deck's own figures box (slide 9) and the guide (p. 4) say 25. The deck gives "$10 BILLION" for each of Phases 1 and 2 and "$10 BILLION +" for Phase 3 (Ignition deck 2, slides 9, 17, 27, 36; Users Guide, p. 4). NASA's documents use five sets of phase names, and the deck's own dates differ from the web pages' (Phases; Figures per phase).
  • CLPS grows. "targeting up to 30 robotic landings starting in 2027" (Ignition release), and a follow-on, CLPS 2.0, "targeted to be capped at $6 billion" (Ignition page). See CLPS.
  • The LTV changes shape. Astrolab and Lunar Outpost were selected in May 2026, at $219 million and $220 million (May 2026 release). Briefed at Ignition, the plan moves from a "fully capable" crewed rover lasting 10 years to Phase 1's "Less complicated rovers, one-year design life" (Ignition deck 2, slides 57–58). The deck's mass and speed figures differ from the release's (open question 82; Lunar Terrain Vehicle).
  • Nuclear power: SR-1, then Lunar Reactor-1. Lunar Reactor-1 (LR-1) is to land in 2030 (Lunar Surface Technology, "Fission Surface Power"), "to keep the Moon Base operating through periods of darkness", with SR-1 flying first (nuclear power fact sheet). Directive 7 asks the Space Reactor Office to plan "SR-1 targeting launch to Mars in 2028, and LR-1 ready for launch by 2030" (workforce note). SR-1's own mission page ties SR-1 itself to the Moon Base: it will "prove fission surface power technology for NASA's Moon Base", "Targeting launch in late 2028" (SR-1 Freedom page). No source puts either in a Moon Base phase. The Moon Base Program Manager, as reported, places "those nuclear reactors in phase three, or you know, at the end of phase two", without naming one (Moon Base podcast; Lunar Nuclear Fission System; Mars-forward).

  • New solicitations since Ignition. Two NextSTEP-3 appendices (NextSTEP-3 is "Next Space Technologies for Exploration Partnerships-3"):

    • Appendix A, the Lunar Enabling Infrastructure Accelerator (LEIA): five topics, among them vertical solar arrays and oxygen production from lunar regolith, matured by "risk reduction and ground‑based testing" to technology readiness level (TRL) 5–6; final solicitation 8 September 2026. NASA ties the topics to gaps "as identified in NASA's Civil Space Shortfalls" and names no ADD gap, so the wiki doesn't match them to the technology gaps (NextSTEP-3 A page; draft-input article; Surface technology).
    • Appendix B, Moon Base Demonstrations (June 2026): HSMD asks for "concept demonstrations, risk reduction opportunities, and studies that address Moon Base architecture gaps", at "TRL 6 and beyond", "culminating in flight or lunar surface demonstrations", surface power first. It names no gap and doesn't say where the "Moon Base architecture gaps" are listed (NextSTEP-3 B page; RT-2).

  • Named missions and payloads. Moon Base I to III, four science landings in late 2028, the NavCube3-mini navigation system and three PRISM science suites: see Missions and assets.

  • Low Earth orbit (LEO). A LEO fact sheet sets out a plan anchored on the International Space Station (ISS), with a NASA core module and commercial modules, which the LEO deck calls the "alternate option" (LEO fact sheet, pp. 1–3; Ignition deck 3, slides 8, 10, 17, 18; RT-8).

Each element page has a "Changes since Rev C" section (Elements). The next ADD revision would be expected after the 2026 review, but no source gives its date, and the realignment sources don't mention the ADD (above).

What the workshop briefings add

NASA's architecture workshops brief its products to outside audiences (Architecture definition process). The slides rank below Rev C. They add history and detail, not a new architecture:

Where the sources disagree, still open

Each page shows both sides. These remain open: in most of them the two documents share a date or one is undated, so the wiki can't simply prefer the newer one. The status of questions 1–71 is in open question 72; the later ones carry their own notes.

Question What disagrees
28 Mars crew: the ADD's "no fewer than six" under consideration against the Update's "up to six"; a January 2026 slide adds a third wording, "the minimum to be up to six (6)"
5, 76 Moon Base phases: the web pages' boundary years sit in two phases each, the Moon Base Program's deck has other dates, and NASA's documents use five sets of phase names
77 "A permanent lunar outpost by 2030" (the Ignition page's summaries of two requests for information, RFIs, and the Science Mission Directorate's (SMD's) Ignition deck) against Phase Three from 2032
79 Gateway: "central" on NASA's undated Artemis page, paused in the Ignition release
82 LTV mass and speed: the Moon Base Program's March deck against the May 2026 release
97 Pressurized Rover missions: "up to 28 days" (ADD Rev C and NASA's Moon Base Phases page) or "up to 30 days" (NASA's undated Moon Base Systems page)
98 Moon Base II and III: "before the end of 2026" (the Administrator's speech of 26 May 2026) or "one this year, and multiple next year" (the Moon Base Program Manager in August 2026, as reported)
31 Mars one-way light time: up to 22 minutes (Update) or up to 24 ("Why Moon and Mars?" paper)
33 Whether the LTV and Pressurized Rover belong to Human Lunar Return (lunar power paper) or Foundational Exploration only (ADD)
37 #1107's use-case pairing, ADD against spreadsheet
38 DN-016 L's data type and one DN-007 L sentence, ADD against spreadsheet
40 The Users Guide's FN-P-102 L carries FN-P-202 L's title
60 Mars gap pairings the Mars decomposition doesn't make
64 ADD Appendix B.3 against B.5 against the lunar spreadsheet's allocation
3, 4 NASA web pages: the minimum temperature in permanently shadowed regions; IPEx's regolith capacity

How to use this wiki

Conventions:

  • Citations. Every claim cites a source page and a page number, sheet row or web-page heading. Quotations are NASA's wording.
  • Links the wiki makes. Where the wiki links two things that no source links, for example by joining function IDs across documents or matching a Moon Base asset to an ADD element, the page says so ("the wiki's join", "the wiki's match").
  • Page numbers. Where a document's printed page numbers differ from the PDF's, its source page says which is used.
  • Open questions. Anything the sources leave unclear goes to open questions. It isn't decided on a page.
