Lunar Utility Rover

Summary. An uncrewed, unpressurized rover that moves "a moderate amount of cargo (thousands of kg)" and payloads, supports EVAs and utilization, and can run under astronaut control, teleoperation from Earth, or semi- or full autonomy (ADD Rev C, p. 61). It could scout landing sites and traverses, do science with its arm, relay data, and maintain other assets. It is a Mobility Systems element, new in Rev C, in the Foundational Exploration segment. NASA added it at the 2025 Architecture Concept Review because of "previously identified needs for additional autonomous lunar surface mobility capabilities" (2025 Architecture Update, p. 5). Four of its six functions are on the Moon Base Phase 1 list of functional gaps (the wiki's join, below).

All page numbers are ADD Rev C unless noted.

NASA's description

"The lunar utility rover is an uncrewed, unpressurized rover that provides cargo and payload mobility, EVA support, and utilization support. It can also transport a moderate amount of cargo (thousands of kg) and will provide power and data interfaces for transported cargo and payloads. It supports multiple operational modes, including local astronaut control, teleoperated (from Earth), semi-autonomous, and full autonomous control. During crewed expeditions, the rover will support longer traverses and increase available science targets by carrying support cargo.

It could explore the lunar South Pole; scout future human and cargo landing sites and traverse paths; and gather data to support utilization objectives. The rover could conduct science activities directly (through operation of its manipulator arm and onboard payloads), and indirectly (through crew support). It could collect, store, and locally distribute data; facilitate communication and utilization data exchange between assets; and capture surface imagery. The rover could also support continuous presence on the lunar surface with capabilities to perform maintenance, repair, and servicing of other assets." (p. 61)

Unlike the Lunar Terrain Vehicle, it carries no crew. Many of its roles are "could" roles in the description, not committed capabilities.

The 2025 Architecture Update

The 2025 Architecture Update (Dec 2025, released with Rev C) gives the rover a page of its own (p. 5). Page numbers in this section are the Update's unless marked ADD.

Why it was added. "The addition of this element at the 2025 Architecture Concept Review responds to previously identified needs for additional autonomous lunar surface mobility capabilities. (See the 2024 Moon to Mars Architecture white paper, 'Lunar Logistics and Mobility,' for more details.) The rover will improve NASA's ability to conduct operations and utilization activities between and during crewed missions" (p. 5). No source file carries that white paper's title (source page), and NASA's White Papers page lists no paper by that name. The 2024 paper on the same subject is "Lunar Mobility Drivers and Needs". It found the LTV and Pressurized Rover "primarily for crew transportation, with limited cargo mobility functions", put the LTV's uncrewed cargo at 800 kg, and called for autonomy "to operate throughout the year" (PDF pp. 1, 3–4). The wiki doesn't treat it as the paper the Update means (open question 30; Mobility Systems).

The need as NASA stated it in 2024. In August 2024 NASA's solicitation for industry studies, NextSTEP-2 Appendix R, said NASA "has identified two gaps in its lunar architecture: an integrated surface logistics architecture and uncrewed surface mobility systems for lunar surface assets", and pointed to the 2024 "Lunar Surface Cargo" and "Lunar Mobility Drivers and Needs" papers and the 2023 "Lunar Logistics Drivers and Needs" paper. It names no paper "Lunar Logistics and Mobility" (Appendix R page, "Solicitation Overview"). Its "uncrewed surface mobility systems" and the Update's "previously identified needs for additional autonomous lunar surface mobility capabilities" share a subject; setting them side by side is the wiki's comparison. No source says the rover came from Appendix R or its studies, whose $24 million in contracts went to nine companies in January 2025 (RT-2).

How its description differs from the ADD's. The Update describes the same rover. Its wording differs from the one-pager in three ways:

• It says the rover provides "utilization opportunities", where the ADD says "utilization support".
• It drops the ADD's sentence on longer traverses and its list of scouting tasks ("explore the lunar South Pole; scout future human and cargo landing sites and traverse paths").
• Where the ADD says the rover "could conduct science activities directly", the Update says that during crewed expeditions it "enables utilization directly through operation of its manipulator arm and onboard payloads, and indirectly by supporting crews" (p. 5).

Functional mapping. The Update prints the six functions the rover is mapped to in the Foundational Exploration segment (p. 5). They match ADD Appendix B.3.11.1 (ADD Rev C, p. 160, checked):

ID	Function (p. 5)	Moon Base Phase 1 functional gap?
FN-M-501 L	Reposition a limited amount of cargo (100s of kg) in the south pole region on the lunar surface	yes, robotics group
FN-M-503 L	Reposition a moderate amount of cargo (1000s of kg) at the south pole region on the lunar surface	no
FN-M-701 L	Operate mobility system(s) in uncrewed mode between crew surface missions	no
FN-A-104 L	Perform robotic manipulation of payloads, logistics, and/or equipment on the lunar surface	yes, robotics group
FN-A-105 L	Interface robotic system(s) with logistics carriers on the lunar surface	yes, robotics group
FN-A-302 L	Provide safeguards for automated asset(s) operating near crew	yes, robotics group

The last column comes from the Users Guide's list (Phase 1 functional gaps); joining the two lists is the wiki's work. Three of the six functions carry the letter A, though the rover is a Mobility Systems element.

In the rest of Appendix B:

• Shared and unique functions. The rover shares FN-M-501 L, FN-A-104 L and FN-A-302 L with the Lunar Terrain Vehicle (p. 159), and FN-M-701 L with the LTV and the Pressurized Rover. It is the only element mapped to FN-M-503 L (1000s of kg) and FN-A-105 L.
• FN-A-105 L is also listed as unallocated. B.5 lists it under UC-A-103 L, "Robotic support of logistic operations on the lunar surface as necessary" (p. 168), the only use case it serves. B.3 maps it to this rover, and so does the lunar spreadsheet, which doesn't mark it Unallocated. The ADD doesn't explain this (open question 64).

Gaps that mention it

None by name (search of both spreadsheets). Gaps on the same tasks include #0805 Autonomous Surface Mobility and Navigation, #0806 Payload Offloading, Handling, and Manipulation and #0501 Robotic Inspection, Maintenance, and Repair. The pairing is the wiki's; the gaps don't name the rover.

By function ID (the wiki's join): one of the rover's six functions, FN-A-302 L, appears in the traceability of three gaps, #1002 Autonomous Monitoring, #1004 Trustworthy Autonomy and #1005 Safe Human-Robot Interaction and Teaming (UC-A-301 L -- FN-A-302 L). The other five don't appear in the tech-gap spreadsheet (search of its text).

Changes since Rev C

None: no source newer than Rev C says anything new about this element. Searched by name across all the wiki's sources, it appears after December 2025 only in the text of the thumbnails of ADD Rev C pages on the 2026 workshops' "Product Revitalization" slide (January 2026 deck, slide 6; February 2026 deck, slides 6 and 22). CSA's "Lunar Utility Vehicle" in the Ignition release is not matched to it (below).

Moon Base relevance

Not established by the sources so far. No source names this rover for a Moon Base phase.

Shared function IDs (the wiki's join). Four of the rover's six functions are on the Users Guide's list of Phase 1 functional gaps. All four sit in its "Autonomous systems and robotics" group: FN-A-104 L, FN-A-105 L, FN-A-302 L and FN-M-501 L (Users Guide, p. 8; 2025 Architecture Update, p. 5). The guide defines functional gaps as "architecture functions that are either currently unallocated to any existing elements, or functions that need additional performance to be fully satisfied" (Users Guide, p. 9). These four are allocated to the rover, but the guide doesn't say which half of its definition applies to them. That group's capability target is "Demonstration of capabilities to unload and manipulate cargo (10kg) on the surface" (Users Guide, p. 8). Neither source makes this link (open question 11). One of the four, FN-A-105 L, is also in the ADD's list of unallocated functions (B.5, p. 168; above; open question 65).

Not matched. The Users Guide's Phase 1 mobility target, "Deployment of small utility rovers and hoppers to conduct science, reconnaissance, and resource discovery" (Users Guide, p. 9), doesn't name this element. It says "small", while this rover carries "thousands of kg" (p. 61), so the wiki doesn't treat them as the same.

Not matched either: CSA's "Lunar Utility Vehicle". The Ignition release names it as a Phase Three contribution from the Canadian Space Agency, with no description (Ignition release, "Building the Moon Base"). This rover's implementing program is NASA's EVA and Human Surface Mobility Program (p. 61), and no source relates the two, so the wiki doesn't.
