Moon to Mars Architecture
NASA’s Moon to Mars architecture represents the hardware and operations needed for human missions to the Moon and Mars, and how they function together as a system. The architecture is not a mission, a manifest, or a set of requirements, but it does define the elements — rockets, spacecraft, rovers, spacesuits, communications relays, and more — that will be incrementally developed and delivered to the Moon and Mars for long-term, human-led scientific discovery in deep space.
NASA is evolving its architecture development approach by moving toward a process that applies a systems engineering method to distill the Moon to Mars Objectives into architectural elements. This process incorporates analysis across all of NASA and important contributions from U.S. industry and international space agencies.
Architecture Concept Review
NASA’s Exploration Systems Development Mission Directorate (ESDMD) is responsible for defining and managing systems development for programs critical to NASA’s Artemis program and planning for NASA’s Moon to Mars exploration approach. ESDMD manages development for human-led lunar orbital, lunar surface, and Mars exploration, works with NASA’s Space Operations, Science, Space Technology, and Aeronautics mission directorates to integrate the science and robotic components, and coordinates with many other internal and external partners to develop the architecture.
ESDMD conducted its first Architecture Concept Review (ACR22) in January 2023 to review the 2022 architecture analysis work. The purpose of the ACR is to help unify the agency, promote advocacy for the architecture, and document the previous year’s architecture analysis. Throughout the year, NASA architecture teams analyze the Moon to Mars Objectives and distill them into mission elements and how they function together to accomplish human missions to the Moon to Mars. Future ACRs will take place annually in November.
The focus of ACR22 was to gain concurrence on the evolutionary process, and to review the architectural analysis conducted in 2022. The resources listed below document the Moon to Mars Strategy and Objectives, overall ACR process, and results of ACR22. These resources are made publicly available to foster open communication with current and future partners that have ambitions to work with NASA and contribute to the architecture.
NASA’s process answers a call from Vice President Harris, as Chair of the National Space Council, to develop a plan for an initial lunar surface architecture which includes commercial and international partnerships.

Architecture Definition Document
This Technical Publication is a snapshot of NASA’s current Moon to Mars architecture. The ADD will be updated following future annual ACRs. This is for highly technical readers who wish to dive into the Moon to Mars exploration strategy campaign segments, the architecture elements and functional allocations, and crewed and uncrewed reference missions for each element. (PDF, 150 pages)
- Objectives Mapping Table
This Excel file, extracted from the ADD, is provided for ease of importing into relevant systems or databases. - NASA’s Moon to Mars Architecture: A Summary of the 2022 Architecture Concept Review
This document is a high-level summary of the Architecture Definition Document, written for technically informed audiences who want to become more familiar with NASA’s Moon to Mars architecture, elements of the architecture and their functional descriptions. (PDF, 18 pages)
Architecture Concept Review 2022 White Papers
These white papers were developed to address topics of frequent discussion in short format. Each is 4-6 pages long. The topics are:
- Systems Analysis of Architecture Drivers
- Why NRHO: The Artemis Orbit
- Why Artemis will Focus on the Lunar South Polar Region
- Gateway: The Cislunar Springboard for International and Sustainable Human Deep Space Exploration
- Mars-Forward Capabilities to be Tested at the Moon
- Mars Transportation
Engagement
NASA has a long, successful history of working with a diverse community of partners to advance common space exploration and science objectives. The agency is committed to building on and broadening these global partnerships.
