Detailed Report
1. Strategic Vision, Context, and Program Architecture
NASA's Moon Base initiative is framed as a transformative leap for the United States and humanity, establishing the first outpost on another celestial world. The lunar South Pole was selected for its near-continuous sunlight and proximity to water ice, both critical for life support and fuel production. The program marks a strategic pivot away from a Gateway-centric model, instead prioritizing direct, modular surface operations through a phased, iterative approach. This structure is designed to maximize operational learning, reduce risk, and accelerate the timeline for sustained human presence. The Moon Base is positioned as a platform for scientific discovery, economic development, technological innovation, and as a proving ground for future Mars missions.
2. Phase One (Now–2029): Learn, Test, Build
Phase One is characterized by a rapid cadence of up to 25 missions, including 21 landings, the delivery of four tons of payload, deployment of crewed and autonomous rovers, four MoonFall drones, communications relay and observation satellites, and demonstrations of power, navigation, communications, and nuclear radioisotope heater technologies designed to endure the long lunar night.
2A. Moon Base I, II, And III
Moon Base I: Targeted for launch no earlier than fall 2026, this mission utilizes Blue Origin's Blue Moon Mark 1 Endurance lander. It will deliver the Stereo Cameras for Lunar Plume-Surface Studies (high-resolution cameras capturing imagery of the lander's engine plume interacting with the lunar surface during descent) and the Laser Retroreflective Array (enabling orbiting spacecraft to determine more precise positioning using reflected laser light). The landing site is the Shackleton Connecting Ridge—a topographically elevated ridge extending from Shackleton crater at the lunar South Pole and renowned for near-continuous sunlight—chosen to demonstrate landing precision and reduce risk for crewed Artemis missions in 2028.
Moon Base II: Planned for launch later this year, this mission will deliver over 1,100 pounds of cargo via Astrobotic's Griffin lander, including Astrolab's FLEX Lunar Innovation Platform (FLIP) rover. The FLIP rover will mature mobility systems and components to inform future lunar terrain vehicle (LTV) operations.
Moon Base III: Also targeted for this year, this mission will fly the first payload selected through NASA's Payloads and Research Investigations on the Surface of the Moon (PRISM) initiative. The anchor investigation, Lunar Vertex (managed by Johns Hopkins Applied Physics Laboratory), will study lunar swirls—naturally occurring light spots on the lunar surface—to improve understanding of surface evolution and material behavior under extreme conditions, including the origins of magnetic anomalies. Launched on Intuitive Machines' Nova-C Trinity lander, the mission includes payloads from ESA and KASI, reflecting international participation. These three missions are the first of more than a dozen to be announced this year, each designed to generate operational data and reduce risk ahead of crewed Artemis surface activities.
2B. Key Missions
VIPER: The Volatiles Investigating Polar Exploration Rover is scheduled for delivery to the lunar surface in late 2027 via NASA's CLPS initiative aboard a second Blue Moon MK1 lander from Blue Origin. VIPER is a mobile robotic explorer equipped with multiple science instruments and a 1-meter drill, capable of analyzing lunar soil at various depths and temperatures to detect volatiles. It can enter permanently shadowed craters—among the coldest locations in the solar system—where water ice may have been preserved for billions of years. VIPER is expected to become the first resource mapping mission on another celestial body, directly informing site planning, resource strategies, and the long-term sustainability of the Moon Base.
CLPS Role: NASA's Commercial Lunar Payload Services (CLPS) initiative is the backbone of Phase One delivery infrastructure, with CLPS 1.0 contracts awarded to Blue Origin, Astrobotic, Intuitive Machines, and Firefly Aerospace. Griffin-1 (Astrobotic) will target landing at Nobile Crater near the South Pole, carrying payloads from NASA, ESA, Venturi Astrolab, and Astrobotic—including Astrolab's FLIP rover with 10 additional payloads, four developed with NASA. Intuitive Machines' IM-3 mission will deliver science and technology demonstrations, including Lunar Vertex and international partner payloads, to the Moon's Reiner Gamma swirl.
2C. Technology
MoonFall Drones: Four drones developed by NASA's Jet Propulsion Laboratory, built on the legacy of NASA's Ingenuity Mars Helicopter. Firefly Aerospace has been selected to build the spacecraft transporting the drones from Earth orbit to the Moon, with launch targeted for 2028. Once deployed, each drone operates independently over a single lunar day (approximately 14 Earth days), making multiple propulsive hops to scout steep terrain, permanently shadowed regions, and hard-to-reach locations that may contain water ice. Equipped with high-definition optical cameras and other instruments, the drones survey terrain and gather imagery for site selection and risk reduction. After each drone's final flight, a survive-the-night payload continues operating for several months, marking a sustained U.S. presence at the lunar South Pole.
Lunar Terrain Vehicles (LTVs): NASA has awarded Astrolab $219 million and Lunar Outpost $220 million under Phase 1 High Achievability Mission task orders of the Lunar Terrain Vehicle Services contract to develop and deliver the first phase of LTVs by 2028 via the CLPS initiative. Astrolab's CLV1 (Crewed Lunar Vehicle 1) is designed to transport astronauts, carry supplies, and support remote operations. Lunar Outpost's Pegasus, a mission-ready evolution of its Eagle rover incorporating Apollo-heritage technologies, is capable of manual, autonomous, or teleoperated operation, with a minimum one-year operational lifespan. Blue Origin received $188 million with an option period worth $280.4 million to deliver these rovers to the Moon's South Pole region.
Radioisotope Heating Units (RHUs): NASA will deploy RHUs to maintain electronics, batteries, instruments, and mechanical systems within safe operating temperatures during the lunar night and in permanently shadowed regions. Unlike Earth, the Moon's lack of atmosphere allows temperatures in shadowed regions to plunge to extreme lows. RHUs use the natural heat released by decaying radioisotope material to provide continuous thermal control independent of sunlight, enabling extended operations in some of the Moon's most extreme environments.
Communications and Navigation: NASA plans to deploy an initial orbital relay constellation followed by a provider-developed constellation to expand capabilities, providing high-bandwidth communications between Earth, cislunar space, and the lunar surface. Early demonstrations will advance LunaNet, NASA's developing lunar communications and navigation architecture designed to enable interoperability standards across systems and providers. These capabilities lay the groundwork for the reliable connectivity needed to support growing science, exploration, and operational demands.
3. Phase Two (2029–2032): Early Habitation and Infrastructure
By 2029, the Moon Base program transitions from exploration and demonstration to the assembly of semi-permanent infrastructure and the initiation of early habitation and logistics operations. Phase Two will involve up to 24 landings delivering as much as 60 tons of cargo using low-, medium-, and heavy-class landers. Key capabilities include expanded solar power systems, initial nuclear surface power, upgraded rovers, enhanced surface-to-orbit communications, and early habitation elements.
3A. Key Missions and Infrastructure
Cargo And Logistics: Up to 60 tons of cargo will be delivered through as many as 24 landings using a mix of low-, medium-, and heavy-class cargo landers. This supports the assembly of early habitation elements, logistics infrastructure, and site preparation. Site preparation and logistics rovers—including NASA's LTV Gen 2 and additional industry and international partner rovers—will support cargo transport, regolith excavation, soil compaction, and terrain preparation near the South Pole.
3B. Technology
JAXA/Toyota Pressurized Rover: Supplied by JAXA, the pressurized rover will serve as a mobile habitat and laboratory, supporting two astronauts in a shirt-sleeve environment for up to 30 days. Designed for an approximate 10-year operational lifespan, the rover can traverse slopes of up to 15 degrees, survive as many as 150 hours in shadow, and reach speeds of up to 2 miles (3.5 km) per hour. It enables moonwalks from remote locations, extending exploration range to geographically diverse regions and resource-rich terrain otherwise inaccessible from fixed habitats.
Nuclear Surface Power (RTGs): Phase Two will deploy radioisotope thermoelectric generators (RTGs) capable of producing hundreds of watts of power, supporting lunar surface systems, lunar night survival, and exploration within permanently shadowed regions. These demonstrations will advance thermal management approaches, operational concepts, and processes intended to inform future large-scale nuclear fission power systems for sustained lunar and Mars exploration.
Solar Power Augmentation: Demonstrations will include deployment of solar array systems with battery energy storage and power distribution hubs. Permanent infrastructure will require generating more than 10 kilowatts of power during illuminated periods and providing up to 360 kilowatt-hours of stored energy during shadow periods.
Surface-To-Orbit Communications: Dedicated surface-to-orbit communications stations will be deployed with coverage ranges of approximately 6 miles (10 km) per node—functioning analogously to terrestrial cellular network towers—to create a more connected and resilient communications architecture across the lunar South Pole region.
4. Phase Three (2032 And Beyond): Sustained Human Presence and Industrialization
Phase Three represents the fulfillment of the Moon Base program's foundational objective—a sustained, semi-permanent human presence with routine crew rotations and continuous surface activity. This phase scales operations to support industrial-scale resource utilization, advanced logistics, and long-duration habitation, with up to 38 tons of cargo delivered annually enabled by low-cost reusable heavy-lift capabilities.
4A. Sustained Operations
Goals include routine crew rotations, continuous surface activity, and expanding the Moon Base into a functioning outpost capable of supporting multiple crews and complex scientific and industrial operations year-round. Advanced logistics networks supported by crewed and autonomous rovers will keep the base supplied and functioning continuously. These operations will serve as a proving ground for future Mars missions and a hub for scientific research and economic activity.
4B. Technology
Habitation Modules: Building on earlier habitation efforts, Phase Three will deploy larger semi-permanent habitation modules with expanded environmental control, power, and life support systems. Infrastructure plans include airlocks and module aggregation nodes designed to support interconnected habitats for longer-duration crew presence.
Operational Fission Surface Power: Advanced fission reactors will supply steady, reliable energy through the long lunar night, leveraging in-situ resource manufacturing for sustained operations. This represents the maturation of the nuclear surface power demonstrations conducted during Phase Two, scaling from hundreds of watts (RTGs) to the continuous power demands of a permanent outpost.
In-Situ Resource Utilization (ISRU): Building on Phase One and Two demonstrations, Phase Three will advance toward sustained ISRU implementation. Planned capabilities include extracting oxygen, water, and hydrogen from lunar regolith to reduce launch mass, operational costs, and dependency on Earth resupply. Additionally, techniques for converting regolith into construction and infrastructure materials will be explored, including sintering (fusing materials using heat without melting), corbelling (a structural building technique), and 3D printing, enabling in-place construction from local materials.
Uncrewed Cargo Return: Phase Three will implement substantial uncrewed cargo return capabilities from the lunar surface to Earth, building on initial Phase Two demonstrations, with systems capable of returning up to 1,102 pounds (500 kilograms) of scientific samples, research payloads, and critical hardware per mission.
Advanced Logistics: End-to-end logistics capacity will expand significantly, increasing per-mission delivery from the 0.5–1.5 metric ton range of Phase Two to as much as 8 metric tons per 28-day mission. These systems will sustain habitats and crews by delivering food, water, clothing, spare parts, science payloads, and maintenance equipment.
5. Commercial and International Partnerships
NASA's Moon Base program is underpinned by a robust network of commercial and international partnerships. Blue Origin is responsible for the Blue Moon MK1 lander delivering Moon Base I payloads and VIPER, with $188 million plus a $280.4 million option for LTV delivery. Astrobotic provides the Griffin lander for Moon Base II and Griffin-1, while Intuitive Machines supplies the Nova-C Trinity lander for Moon Base III and IM-3. Firefly Aerospace is tasked with MoonFall spacecraft transport. Astrolab ($219 million, CLV1 rover) and Lunar Outpost ($220 million, Pegasus rover) are developing advanced lunar terrain vehicles. JAXA and Toyota are supplying the Phase Two pressurized rover. ESA and KASI contribute science payloads on Griffin-1 and IM-3, and Johns Hopkins Applied Physics Laboratory manages the Lunar Vertex investigation. Venturi Astrolab is listed as a payload provider for Griffin-1. The CLPS 2.0 initiative will further expand the commercial partner pool.
