sources/raw/slides/2025-02-2025-ia-workshop-wp-architecture-driven-technology-gaps/. Slides 4 and 5 were read
from the images (the tables). Slide 1, the only text-poor slide, is the title slide; its text gives title and
presenter, and its image was not viewed. No "Moon Base", "CUI" or "Pre-Decisional" in the text (searched).
What it is. A briefing of the 2024 white paper Architecture-Driven Technology Gaps, given at the industry and academia workshop in February 2025, before ADD Rev C. The partners' workshop had the same slides under another presenter (international copy). It is older than Rev C: the reference for today's gaps is the December 2025 spreadsheet and ADD Rev C Appendix D (gaps index).
What it adds to the paper. One thing of weight: Revision B's whole prioritized list, all 56 gaps with their ranking and bin (slide 5). The paper printed only the five highest, unnumbered. The list is transcribed below, and compared with Rev C on the gaps index. Slide 4 also prints #0301's Rev B table as its example. The rest repeats the paper.
Slides¶
| Slide | Title, as printed | What it holds |
|---|---|---|
| 1 | Technology Gaps: Definition and Prioritization | Title and presenter |
| 2 | NASA Architecture-Driven Technology Gaps (Why and What) | The decomposition chain from "Objectives and Goals" through "Characteristics and Needs" and "Use Cases and Functions" to "Tech Gap", "Decisions" and "Tech Dev"; four bullets; a link to the white paper |
| 3 | NASA Architecture-Driven Technology Gaps: Annual Definition and Prioritization Process (How) | "Annual processes using systems engineering tools governed by strict principles to enable rigorous, repeatable results"; the paper's figure caption |
| 4 | NASA Technology Gaps (in ADD Rev B, Appendix C): Communicating Details (Example Gap Shown) | What each field holds and who supplies it; #0301's Rev B table |
| 5 | NASA Technology Gaps Priority Bin Results (in ADD Rev B, Appendix C) | All 56 gaps with ranking and bin |
| 6 | NASA Architecture-Driven Technology Gaps: Looking Forward and Summary Overview | Annual updates; what, where, when, why, how |
What the gap is, as briefed (slides 2, 3, 6)¶
- Four bullets (slide 2): "Demand signal used globally to inform technology investments that align to NASA's Moon to Mars Architecture"; "Derived from needed capability in the architecture but solution-agnostic"; "Included in Shortfalls list, providing technology pull from the architecture for Moon to Mars missions"; "Updated annually as architecture evolves and technology development close gaps". The paper says the same in prose (2024 paper, pp. 1–2).
- Slide 3's caption is the paper's Figure 2 caption: "NASA identifies technology and capability gaps in the Moon to Mars Architecture through the objective decomposition process. NASA prioritizes and documents gaps in the Architecture Definition Document and relies on technology development to close them."
- Looking forward (slide 6): "Updates to gap definition and priorities occur annually in our strategic analysis cycle", "As architecture evolves (new functions, decisions, priorities)", "As technologies are developed (gap closure)", "Coordinated with NASA Civil Space Shortfalls". Then: "What: Prioritized technology development demand signal from architecture. Where: Architecture Definition Document. When: 2024 → Annually revised. Why: Focus resources to enable critical technologies for Moon to Mars exploration. How: Rigorous systems engineering processes and stakeholder integration."
Who supplies each field (slide 4)¶
The slide's "Gap Details" list says where each part of a gap table comes from. ADD Rev C says only that "Input from the architecture teams ensures the gap data is fully aligned with the current state of the architecture" (ADD Rev C, p. 77); it doesn't name technology domain experts as the source of the state of the art (the wiki's comparison):
- "Gap number, title, and description"
- "Architecture impact and benefits from architecture teams"
- "Current state-of-the art metrics sourced from technology development domain experts"
- "Target performance metrics sourced from architecture teams"
- "Traceability to sub-architectures, segments, UC/Fs and decisions"
- "Priority bin based on Gap Overall Prioritization Rating sourced from architecture teams"
- "Related Child Gaps are more specific"
(Bold as printed.) "UC/Fs" is use cases and functions.
#0301 in Rev B (slide 4, read from the image)¶
The example table is #0301, "Systems to Survive and Operate through Extended Periods of Lunar Shadow", in the layout of ADD Rev C's Appendix D tables. The wiki's comparison with the December 2025 row (Tech gaps spreadsheet, ESDMD #0301):
| Field | Rev B, as briefed | Rev C |
|---|---|---|
| Title, description, impact and benefits, current state of the art | as Rev C | as Rev B, word for word |
| Child gaps | 0301-01 to 0301-04, as Rev C | the same four |
| Use cases and functions | "UC-H-105 L -- FN-H-201 L" | the same |
| Key decision | blank | "✓LD-03-L Lunar Landing Region Selection" |
| Performance target | "Survive continuous shadow for 150 (TBR) hours or more several times a year for 10 years." | "Survive continuous shadow for 350 hours or more several times a year for 10 years." |
| Sub-architectures | three icons: Habitation Systems, Mobility Systems, Autonomous Systems and Robotics | the same three |
| Segments | two icons: Foundational Exploration, Sustained Lunar Evolution | the same two |
| Priority | a shaded scale marked "Higher Priority" with a "!" at the top; no number | bin 1, rating 3 |
The target more than doubled and lost its "(TBR)". No source read says why. Slide 5 ranks #0301 second in Rev B (below).
Rev B's prioritized list (slide 5)¶
Titled "NASA Technology Gaps Priority Bin Results (in ADD Rev B, Appendix C)", with the banner "Prioritized technology gaps are grouped in bins by similar levels of preference according to the Moon to Mars Architecture perspective". Two tables: 27 gaps in bins 1–3 and 29 in bins 4–6, 56 in all, the count the 2024 paper gives ("The initial list included 56 total gaps"). Bins were read from the image, where each bin is one merged cell. Titles as printed; the text layer splits some words ("D ust", "Diag nosis"), the image doesn't.

Ties as printed: 37 three times (then 40), and 53 twice (then 55). Rev C prints no ties.
Bins: 1 (ranks 1–5, five gaps), 2 (6–15, ten), 3 (16–27, twelve), 4 (28–33, six), 5 (34–46, thirteen), 6 (47–56, ten).
The paper's Table 1 follows this order. The 2024 paper's five gaps, in the PDF's row order, are #0801, #0301,
0103, #1104, #0201 (2024 paper, Table 1):¶
ranks 1 to 5 here. The wiki reads the table's rows as Rev B's top five in rank order.
"Appendix C". Both slide titles put the gaps in Rev B's Appendix C. That fits the February 2025 Architecture Updates deck, which lists Rev B's appendices with C for technology gaps (Architecture Updates deck); Rev C prints them in Appendix D.
Rev B titles that differ from the December 2025 sheet (the wiki's comparison, beyond hyphens):
| Gap | Rev B, as printed | December 2025 sheet |
|---|---|---|
| #0101 | Lunar Surface Position, Navigation, and Timing Systems for Extreme Temperature, Radiation, Dust | Positioning, Navigation, and Timing for Lunar Surface Extreme Environments |
| #0304 | Habitat Environmental Monitors Capable of Supporting Deep Space Missions | Habitat Environmental Monitors and Capabilities to Support Deep Space Missions |
| #0305 | Food and Nutrition Capabilities for Missions with Long-duration Storage | Food and Nutrition Capabilities for Long-Duration Missions |
| #0307 | Radiation Monitoring and Modeling | Radiation Monitoring and Forecasting |
| #0501 | Robotic and Human-Robot Inspection, Maintenance, and Repair | Robotic Inspection, Maintenance, and Repair |
| #0701 | Packaging, Transport, and Use of Conditioned Supplies and Commodities | Packing, Transport, and Use of Conditioned Supplies and Commodities |
| #0803 | … Suit System Capabilities for Mars Missions | … Suit System and Capabilities for Mars Missions |
| #0804 | Robotic and Mobility Systems in Extreme Cold Environments | … Extreme Cold Environments on the Lunar Surface |
0101's Rev B title is also not the one the 2024 executive overview printed ("Lunar Surface Positioning,¶
Navigation, and Timing Systems for Extreme Temperature, Radiation, and Dust"; #0101). #0602's title is the one the 2025 Architecture Update gives for the gap Rev C removed (gaps index).
Oddities¶
- "State-of-the art" (slide 4), as printed.
- "technology development close gaps" (slide 2), as printed.
