Lunar Terrain Vehicles

Program Framework and Procurement

NASA structured the LTVS procurement in three phases. Phase 1 comprises approximately 12-month feasibility studies intended to bring competing designs to preliminary design review (PDR) level maturity. Phase 2 is a demonstration mission: NASA will issue a request for task order proposals to eligible providers who will develop, deliver, and demonstrate an LTV on the Moon, validating performance and safety ahead of the first crewed use on Artemis V. NASA anticipated awarding only one provider for the demonstration task order. Follow-on annual service task orders will support unpressurized rover capabilities for moonwalking and science through approximately 2039. The contract also includes on-ramp provisions allowing additional companies to compete in later phases.

On 3 April 2024, NASA selected Intuitive Machines, Lunar Outpost, and Venturi Astrolab for Phase 1 feasibility task orders. Each company received a 12-month award to mature its rover design. Testing of all three commercially owned and developed LTVs subsequently began at Johnson Space Center, focusing on mobility, control, and integration with NASA extravehicular activity (EVA) operations in a terrestrial analogue setting.

NASA has not publicly issued a single fixed engineering specification sheet common to all vendors. Instead, it specifies performance and safety requirements — including crewed and autonomous operation, advanced power management for the low-sunlight polar environment, autonomous navigation and hazard avoidance, and state-of-the-art communications — and each company proposes a rover design meeting or exceeding those thresholds. The overarching operational requirement is that LTVs must function both with astronauts aboard and independently, enabling continuous exploration of the lunar south pole between crewed visits.

Rover Specifications: Pegasus and CLV-1

Both Phase 1 rovers share a common NASA-driven performance envelope. Each has a mass of a little less than one metric ton, is stowed in a folded configuration to fit within Blue Origin's Blue Moon Mark 1 lander (which can carry up to approximately 3,000 kg to the lunar surface), and is designed to carry up to two suited astronauts. Nominal crewed traverses cover approximately 10 km at speeds up to about 10 km/h (roughly 6 mph). In uncrewed or autonomous mode, both rovers are designed for excursions of up to approximately 200 km from their delivery point. The south polar operating environment demands that rovers handle permanently shadowed regions, rugged terrain, regolith dust, and extreme thermal conditions.

The Pegasus rover, under contract to Lunar Outpost, is described by NASA as designed to operate for up to a year on the lunar surface. It supports manual, autonomous, and teleoperated driving modes and is capable of speeds exceeding 9 mph (approximately 14–15 km/h). Pegasus draws on Apollo-heritage design concepts and on prototype and flight experience from Lunar Outpost's earlier Eagle rover and MAPP robotic platform family. Its design features a flight deck-forward configuration for improved terrain visibility, a reconfigurable cargo bed, and a robotic arm. A key thermal technology allows Pegasus to operate — not merely survive — during the approximately two-week lunar night, when surface temperatures fall to around –173 °C (–280 °F), extending operational life from days to potentially many years.

Venturi Astrolab's CLV-1 is similarly rated for crewed traverses of approximately 10 km and autonomous excursions of up to about 200 km. It supports remote teleoperation from Earth and autonomous navigation. One CLV-1 variant is configured with an Interlune imaging system intended to search for helium-3 deposits during robotic sorties. NASA characterizes the Artemis-era LTV class as a combination of Apollo-style crewed mobility and Mars-rover-like autonomy and endurance.

Blue Origin: Delivery Architecture

Blue Origin is not constructing an LTV; its role is to deliver the Lunar Outpost and Venturi Astrolab rovers to the lunar surface. The delivery vehicle is the Blue Moon Mark 1, an autonomous cargo lander approximately 8.05 m tall and 3.08 m in diameter, with a fueled mass of about 21,350 kg. Its single BE-7 engine burns liquid oxygen and liquid hydrogen, producing up to approximately 44 kN of thrust. Launched in the fairing of Blue Origin's New Glenn rocket, the Mark 1 can deliver up to approximately 3,000 kg of cargo anywhere on the lunar surface, sufficient to accommodate both LTVs (each under one metric ton) along with associated equipment.

Blue Origin holds a $188 million initial contract to ready the lander and mission integration for LTV delivery, with an option period worth a further $280.4 million for two task orders. The delivery is structured under the Commercial Lunar Payload Services (CLPS) 1.0 IDIQ framework as a CX-2 task order. The first LTV delivery is targeted ahead of Artemis IV, currently expected around 2028, so that rovers are already present on the surface for the crewed landing. The Moon Base I mission — an uncrewed demonstration using Blue Moon Mark 1 Endurance — was targeting a launch no earlier than fall 2026, with a landing at Shackleton Connecting Ridge near the lunar south pole, to reduce risk and demonstrate surface systems ahead of crewed Artemis landings.

Lunar Outpost MAPP: Robotic Prospecting Rovers

Alongside its crewed LTV program, Lunar Outpost has developed the MAPP (Mobile Autonomous Prospecting Platform), a family of small robotic rovers designed for commercial resource prospecting and payload delivery on the Moon. MAPP is positioned as a precursor and technology feeder for Lunar Outpost's human-rated LTV work.

The baseline MAPP platform (M1 MAPP) has a total mass of approximately 10 kg — a 5 kg rover carrying a 5 kg payload — with overall dimensions of roughly 45 × 38 × 40 cm sized to fit within standard CLPS lander payload volumes. Its top speed is approximately 10 cm/s. Range is up to 8 km per mission, and the rover provides up to 35 W of peak payload power across five separate payload bays. The COLD-MAPP variant is a cryogenic, long-duration rover rated for up to 20 km of driving and capable of surviving one or more lunar nights, with a platform mass of 15 kg. The PSR-MAPP variant is optimized for exploration of Permanently Shadowed Regions using cryo-capable wheel drives and advanced vision-based navigation merged with lidar point-cloud data. At the large end of the family, the HL-MAPP (Heavy-Lift MAPP) is a 300 kg rover platform providing up to 80 kg of payload accommodation, 85 W of peak payload power, a mission duration of 150 Earth days, and a range of up to 35 km from its lander.

The Lunar Voyage 1 MAPP rover reached the lunar surface aboard Intuitive Machines' IM-2 Nova-C lander. Although the lander came to rest on its side in a crater, complicating deployment, MAPP collected data and demonstrated readiness to drive. The mission achieved Lunar Technology Readiness Level (TRL 9) for key rover subsystems and for Lunar Outpost's Stargate Mission Control Software, which maintained 99.998% uptime. Separately, NASA funded development of a Lunar Vertex MAPP rover for a mission to the Reiner Gamma magnetic anomaly through its PRISM program, carrying a vector magnetometer developed by Johns Hopkins APL and a multispectral microscope to investigate lunar swirls. MAPP has also been selected to provide mobility for Nokia's LTE/4G Lunar Surface Communications System in collaboration with Intuitive Machines and NASA, aimed at establishing the first cellular network on the Moon.

Soviet Lunokhod Rovers (1970–1973)

The Soviet Union flew two Lunokhod teleoperated rovers, predating any crewed lunar rover. Both were large, heavy vehicles — approximately 756–840 kg — carried to the Moon by Luna spacecraft and driven remotely by a five-person team at the Deep Space Center near Moscow. Each had eight aluminum wire-mesh wheels of 51 cm diameter, with two-speed electric motors and independent suspension, allowing the rover to continue driving even if two wheels on each side were disabled. Lunokhod 1 could handle slopes of up to 45°. Operating speed was limited to approximately 1–2 km/h. Power came from a solar array on the underside of a hinged lid, rated at 180 W for Lunokhod 1; a polonium-210 radioisotope heater unit kept the interior warm during lunar nights when surface temperatures fell to around –150 °C.

Lunokhod 1 landed on 17 November 1970 and operated for approximately 322 days — far exceeding its planned three-lunar-day design life — covering 10.54 km and returning more than 20,000 television images and over 200 panoramas. It also carried a French-supplied laser retroreflector that has been used for Earth–Moon distance measurements via laser ranging. Lunokhod 2, which landed in January 1973, incorporated higher-resolution cameras and roughly twice the top speed of its predecessor. It traveled approximately 37 km over about four to five months of operation, a record for distance driven on another world that stood until NASA's Mars rover Opportunity surpassed it decades later. Navigation was entirely dependent on real-time video feeds; there was no onboard autonomous driving. The main advance from Lunokhod to modern rovers lies in software and autonomy rather than in basic mechanical or power design philosophy, which remains broadly similar.
