Rank and method. A program briefing, not the architecture of record (SCHEMA, "Workshop slides"), older than Rev B and Rev C, and older than the March 2026 restructuring of Artemis. It shows the Artemis campaign as planned in February 2024; its content goes in "In the February 2024 workshop briefing" lines. All 18 slides were read in the text layer; the images of slides 1 (text-poor), 2, 3, 4, 13 and 16 were viewed. The text has no "Moon Base", "CUI" or "Pre-Decisional" (searched).
Summary. The Moon to Mars Program Office: what it does and how it is organized; the Artemis missions I to V with their "firsts", "new elements" and "common elements"; Artemis II and III milestone charts and hardware photos. It is the February 2025 Program Office deck a year earlier: the mission slides match it closely (what differs). Two things are in neither that deck nor the ADD: an example of how an architecture use case flows down to program requirements (slide 4), and the HLS uncrewed mission milestones on the Artemis III chart (slide 13).

The Program Office (slide 2)¶
"The Program Office":
- "Helps ensure that NASA successfully establishes a long-term lunar presence needed to prepare for humanity's next giant leap to the Red Planet"
- "Focuses on hardware development, mission integration, and risk management functions for programs critical to the agency's exploration approach that uses Artemis missions at the Moon to open a new era of scientific discovery and prepare for human missions to Mars"
- "Leads planning and analysis for long-lead developments to support human Mars missions"
"Artemis Programs under the Program Office": a "Transportation System Theme: Orion, Space Launch System, Exploration Ground Systems" and a "Lunar System Development Theme: Gateway, Extravehicular Activity and Human Surface Mobility Program (EHP), Human Landing System (HLS), Mars Campaign Office (MCO)".
The organization chart, read from the image: under the "Office of the Associate Administrator", the "Strategy and Architecture Office", the "Moon to Mars Program Office" and the "ESDMD Business Office" (all HQ); below them the Mars Campaign Office, the Safety and Mission Assurance Office, the "Systems Engineering and Integration Office" and the Program Planning and Control Office (all HQ), and Exploration Operations (JSC); and six programs: EVA and Human Surface Mobility (JSC), Exploration Ground Systems (KSC), Gateway (JSC), Human Landing System (MSFC), Orion (JSC), Space Launch System (MSFC). "*Strategy and Architecture and SE&I have direct integration with SMD and STMD."
The chart puts the Strategy and Architecture Office, which leads the architecture, beside the Program Office, not under it; the element initiation breakout says "SAO leads architecture and strategy until acquisition strategy", then "M2MPO leads implementation and mission execution" (the pairing is the wiki's).
Requirements flow-down (slide 4)¶
"Implementing the Architecture"; "Requirements Flow Down for Use Case 001: Crew and supporting system(s) transit from Earth to cislunar space". Four columns joined by lines, read from the image, right to left: "ESDMD-001 Use Case", "ESDMD-001 Functions", "ACD-50007 ConOps Capabilities", "Requirements". ESDMD-001 is the ADD's document number (ADD Rev C); the deck doesn't expand "ACD-50007", "ACD-R" or "CESD-R", and the wiki doesn't either.
| ESDMD-001 function (as printed) | ACD-50007 ConOps capability | Requirements |
|---|---|---|
| F-004-L Enable vehicle launch(es) | A.1.3 Enable Vehicle Launch | CESD-R-31 Day/Night Operations; CESD-R-34 Launch Azimuth; CESD-R-35 Liftoff Clearance; CESD-R-30 Pad Stay Time |
| F-003-L Manage consumables and propellant | A.3.10 Manage Consumables and Propellant | CESD-R-24 Orion Propellant Tank Loading; CESD-R-33 Prelaunch Stable Replenish Hold Time |
| F-006-L Enable abort(s) to safety | A.6.2 Provide Aborts | ACD-R-9 Cis-lunar Aborts Capability; ACD-R-22 Loss of Crew; CESD-R-16 Loss of Crew; CESD-R-40 Mission Abort |
| F-001-L Provide ground services | A.1.1 Provide Ground Services | ACD-R-32 Systems as Space Launch System Co-Manifested Payload |
| F-005-L Allow multiple launch attempts | A.6.1 Provide Multiple Launch Attempts | CESD-R-32 Launch Attempts; CESD-R-15 Launch Rate; CESD-R-30 Pad Stay Time |
| F-002-L Stack and integrate system(s) | A.1.2 Stack and Integrate | ACD-R-32 Systems as Space Launch System Co-Manifested Payload; CESD-R-26 Block 1B and Block 2B Co-Manifested Payload Volume; CESD-R-12 Payload Fairings |
| F-007-L Transport crew and crew system(s) from Earth to cislunar space | A.2.1 Provide Flight Performance | ACD-R-20 Crewed Lunar Orbit Destinations; ACD-R-34 Solar Electric Propulsion; CESD-R-28 Cislunar Element Delivery; CESD-R-11 Lift Capability; CESD-R-37 Low Earth Orbit (LEO) Loiter; CESD-R-13 Orbital Insertion Accuracy; CESD-R-5 Orion Control Mass; CESD-R-25 SLS TLI Capability |
All seven functions feed "UC-001-L Crew and supporting system(s) transit from Earth to cislunar space". The IDs
are plain three-digit numbers with "-L", like the Rev A function IDs a February 2025 briefing prints, though that
briefing writes "FN-018-L" where this slide writes "F-004-L"
(logistics briefing, 2025; the wiki's comparison).
Rev C's IDs carry a sub-architecture letter and a numbered group (FN-T-107 L;
Use cases and functions). Rev C has a function "Enable crew
habitation during transit from Earth to cislunar space" (FN-T-107 L), but the wiki hasn't matched UC-001-L or
F-001-L to F-007-L to Rev C IDs. The slide is the only source the wiki holds that shows the step below the ADD's
functions: Rev C's decomposition figure draws "Design Reference Missions / ConOps" and "Elements / Requirements"
at "Program Level" (Objective decomposition).
Artemis I to V as planned in February 2024¶
As printed (slides 7, 12, 16, 18).
| Mission | "Artemis firsts" | "New elements" | "Common elements" |

Artemis II also lists "ENSURING CREW SAFETY: Addressing a battery issue and a circuitry component responsible for air ventilation and temperature control in Orion, and investigating root cause of char loss from the Artemis I heat shield" (slide 7). No slide gives a year for Artemis III, IV or V.
Against the February 2025 deck¶
The wiki's comparison with the February 2025 Program Office deck. The plan held for a year; the wording moved:
- Artemis II. 2025 adds "Active Orion Launch Abort System (LAS)" and "Proximity operations demonstrations" to the firsts; 2024's common element is "Mobile Launcher 1 and upgraded ground systems", 2025's "Mobile Launcher 1".
- Artemis III. 2024 names providers for both new elements, "SpaceX Starship human landing system" and "Axiom advanced spacesuits"; 2025 has "Starship human landing system" and "Advanced spacesuits". 2025 adds "and return" to the South Pole landing.
- Artemis IV. Identical new elements, including "SpaceX Sustaining Starship HLS" and the Gateway modules. 2024's "Deep Space Logistics flight to Gateway" is a "Precursor" flight in 2025; "Gateway space station" became "Gateway".
- Artemis V. Identical firsts and new elements; 2024 lists two more common elements (Gateway and Deep Space Logistics; science and technology "in orbit and on the surface").
Both plans are superseded: NASA's March 2026 fact sheet made Artemis III an Earth-orbit test in 2027 and moved the first landing to Artemis IV, "early 2028" (Going back to the Moon). The topic page is Human Lunar Return.
The Artemis III milestones (slide 13)¶
"Rev. H - As of 2/15/2024", read from the image: about 50 milestone boxes, the first nine checked (among them "ICPS-3 Engine Delivery to ULA", "Motor Segments Complete" and "Orion Crew Module Adapter Complete"), from "NASA Docking System (NDS) Complete" to "Roll to Pad for Launch". Blue boxes are keyed "New milestones for Artemis III": among them "xEVAS Primary Life Support System Complete", "xEVAS Pressure Garment System Complete", "xEVAS HITL Vacuum Test Complete", "EHP – xEVAS Ready for Integration", "HLS Lunar Lander Launch" and "HLS Lunar Orbit Checkout Review (LOCR) Mission Ready". A row headed "HLS Uncrewed Mission Milestones": "HLS - Starship/Super Heavy Flight Test Complete" (checked), "Propellant Transfer Flight Test Complete", "Long Duration Flight Test Complete", "LC-39A Updates", "HLS Uncrewed Lunar Landing Demo Launch Complete", "Science Instrument(s) Delivery for HLS Integration".
The HLS uncrewed landing demonstration and the propellant transfer flight test are in no other source the wiki holds (a search of all source texts across line breaks; the only other "uncrewed lunar landing" is Blue Origin's Blue Moon Mark 1 on the Moon Base Phases page, a different mission). See Human Landing System.
Oddities¶
As printed, images checked:
- "Charlie Blackw ellThompson" and "countdow n" in the text layer (slide 11); the image is correct.
- "Mobile Launcher 1" and "Mobile Launcher 2" listed among "new" and "common elements", as in 2025.
- The Artemis IV slide runs SLS Block 1B and Mobile Launcher 2 into one bullet (slide 16, image).
- "Block 1B and Block 2B Co-Manifested Payload Volume" (slide 4): Rev C's SLS variants are Block 1, 1B and 2, with crew and cargo forms (SLS); "Block 2B" is in no other source text (searched).
