At NASA’s MAX POWER aerospace expo at Kennedy Space Center on Saturday, NASA Administrator Jared Isaacman stood before a crowd of contractors, engineers, and policy watchers and announced something the agency had never before attached real dollars to: a binding procurement framework for the Moon Base, complete with named vendors, specific contracts, and a machine already on the floor at JPL waiting to be adapted for a destination 240,000 miles away.

The centerpiece of the announcement was a contract awarding Blue Origin $94 million — with a $140 million performance option that could raise the total to $234 million — to carry the PROMISE rover to the lunar south pole. PROMISE stands for Polar Rover for Observation, Mapping, and In-Situ Exploration. It is a six-wheeled science rover being assembled at NASA’s Jet Propulsion Laboratory from engineering test models and spare flight components left over from the Curiosity and Perseverance Mars missions. And unlike any other rover NASA has ever sent to the Moon, it carries an onboard nuclear generator.

Wrapped around that headline mission is the Commercial Lunar Payload Services 2 contract — CLPS 2 — a 10-year, $10 billion ceiling indefinite-delivery, indefinite-quantity vehicle naming eight companies as approved Moon Base cargo carriers: Blue Origin, Firefly Aerospace, Intuitive Machines, ispace-US, Lockheed Martin Space, Northrop Grumman Space Systems, SpaceX, and Voyager Technologies. Also announced: approximately $1.3 billion in venture-class transportation task orders, a new cislunar communications demonstration mission for SpaceX’s Starship, and an infrastructure contract for a modular power and comms tower that will serve as the first permanent fixture at the Moon Base site.

“We are building the Moon Base mission by mission,” Isaacman said in a statement released alongside the announcement. “Today’s announcements expand nearly every part of that campaign, using the playbook that carried NASA through its greatest eras: fly often, learn, apply those lessons, and get more capable with every mission. When our astronauts return to the Moon, they will arrive with the first elements of the Moon Base already waiting for them on the surface.”

What Is CLPS 2 — and What Does $10 Billion Actually Mean?

The first thing to understand about CLPS 2 is what it is not: it is not a promise to spend $10 billion. It is an indefinite-delivery, indefinite-quantity vehicle — an IDIQ — a legal structure that creates a pre-qualified vendor pool from which NASA can competitively award specific task orders over the contract’s lifetime. The ceiling is a cap, not a commitment. The eight companies named today have not each received a check; they have each received the right to compete for task orders as NASA determines what it needs and when.

This is by design, and it reflects the philosophy Isaacman laid out in his pre-confirmation “Project Athena” blueprint — a 62-page document he published in November 2025 advocating for NASA to shift from cost-plus development contracts toward the kind of commercial service purchasing that CLPS 1.0 piloted. The original CLPS program, launched in 2018, originally carried a $2.6 billion ceiling. NASA raised that ceiling to $4.2 billion earlier this year, with deliveries running through November 2033.

CLPS 2 is the successor: a larger pool, a longer runway, and a broader mission scope explicitly designed to serve the Moon Base program rather than individual science payload delivery. The eight vendors are not all building identical landers. They include legacy defense primes (Lockheed Martin, Northrop Grumman), New Space heavyweights (SpaceX, Blue Origin), specialist lander companies (Intuitive Machines, Firefly, ispace-US), and Voyager Technologies — the company that acquired Astrobotic in July 2026 and inherited its Pittsburgh-built Griffin-class landers.

The CLPS model has had a mixed record. Astrobotic’s Peregrine Mission 1 was lost to a propellant leak in January 2024. Intuitive Machines’ Odysseus reached the lunar surface in February 2024 but tipped on its side, partially limiting science operations. That said, Odysseus was the first American soft landing in 52 years, and NASA’s deliberate policy of accepting commercial mission risk — paying for deliveries rather than development — means the agency does not write off failed missions the way a cost-plus development program would. The CLPS 2 structure carries that philosophy forward at scale.

The PROMISE Rover: Mars Engineering, Lunar Mission

The PROMISE rover is the most technically singular element of today’s announcement and deserves careful attention.

JPL has maintained engineering test models — also called engineering development units (EDUs) — of both Curiosity and Perseverance as ground-truth replicas of the rovers on Mars. When engineers need to test a software fix or a new hardware procedure before uploading it to the actual Mars rovers, they run it on these Earth-bound twins first. PROMISE will be assembled from those models and from spare flight components that were built for the Mars missions but never flown. The result is a rover that is mechanically proven — not a new design that has never touched Martian terrain.

The six-wheel rocker-bogie suspension system that lets Curiosity and Perseverance navigate rocks up to 50 centimeters (19.7 inches) tall and slopes up to 30 degrees will work identically on the Moon. The NASA HPSC (High-Performance Spaceflight Computing) processor, a rad-tolerant computing platform for autonomous navigation in GPS-free environments, will allow the rover to traverse the edge of permanently shadowed craters without real-time human guidance — essential when Earth-to-Moon signal delay makes split-second commands impossible.

What makes PROMISE different from every other rover NASA has ever sent to the Moon is its power source. Rather than solar panels, PROMISE carries a Multi-Mission Radioisotope Thermoelectric Generator — an MMRTG — that converts the heat from decaying plutonium-238 into electricity through a process called the Seebeck effect. When two dissimilar conductors are joined and one end is heated while the other remains cold, a voltage appears across the junction proportional to the temperature differential. Repeat that across hundreds of thermoelectric couples connected in series, and you get a compact, highly reliable electrical source with no moving parts.

The MMRTG on Curiosity has been running for more than 14 years on Mars. Beginning-of-life output is approximately 110 watts of electrical power, declining roughly 1.6 percent per year as the plutonium-238 decays. For PROMISE, the cold side of that temperature differential will be helped enormously by the lunar south-pole environment: permanently shadowed craters reach temperatures as low as 25 K (−248°C / −414°F) — among the coldest naturally occurring places in the solar system. The greater the temperature differential across the thermoelectric couples, the more efficient the conversion. PROMISE will draw power in conditions that would kill a solar-powered rover before it took its first sample.

The science instrument stack includes a drill capable of extracting regolith from approximately 1 meter (3.3 feet) below the surface — deeper than any previous lunar surface mission — plus spectrometers to analyze volatile content in the extracted material, cameras for navigation and science context, and temperature and radiation sensors to characterize the permanently shadowed region environment for future human-rated system design.

Target deployment: 2028, with an 18-month surface mission. The delivery vehicle is Blue Origin’s Mark 1 lander, launched on a Blue Origin rocket to be identified closer to the mission date.

Why the South Pole — and Why This Rover’s Drill Results Matter More Than You Think

The lunar south pole has been NASA’s target since the LCROSS impactor mission in 2009 confirmed water ice in the debris plume from Cabeus crater. Subsequent data from Chandrayaan-1’s Mini-RF radar and NASA’s Lunar Reconnaissance Orbiter have identified widespread surface-ice deposits across the south pole’s permanently shadowed regions. Estimates from the scientific literature put total polar ice reserves in the hundreds of billions of tons.

But those estimates come from orbital and surface-impact observations. What they cannot tell scientists — and what Moon Base planners urgently need to know — is what the ice looks like at depth. Is it concentrated pure ice or sparsely mixed through regolith? Is there more of it one meter down than at the surface, or less? How much energy would it take to extract and purify it? No mission has yet drilled into the ice.

This is where PROMISE’s scientific role becomes structurally central, not merely interesting. The Moon Base’s sustainability model assumes in-situ resource utilization — ISRU — in which south-pole water ice is extracted, electrolyzed into hydrogen and oxygen, and used as rocket propellant and life-support oxygen, reducing or eventually eliminating dependence on Earth-launched consumables. But no ISRU system has been designed to a confirmed ice-concentration specification, because that specification does not yet exist.

PROMISE’s drill is the instrument that will produce it. Spectrometer data from subsurface samples at multiple permanently shadowed region sites will give engineers the first ground-truth numbers: the concentration, the form (pure ice versus ice-bound regolith), and the thermal properties of the resource the entire Moon Base propellant economy depends on. If those numbers are favorable, they validate the architecture. If they are not, they tell engineers exactly what the architecture needs to change.

“In the eight months since Ignition, we’ve made incredible strides in accomplishing the near impossible: establishing a permanent outpost on the lunar surface,” said Carlos García-Galán, Moon Base Program Manager. “We’ve consolidated numerous efforts into a streamlined program, evolving our human exploration architecture into an iterative and sustained campaign for Moon Base technology development and implementation. Most importantly, we’ve taken action, awarding new contracts and forging new partnerships to accelerate development.”

Who Got What: A Full CLPS 2 Roster Breakdown

Blue Origin carries the highest-profile mission — PROMISE delivery at $94 million base, $234 million maximum — but also holds a significant share of the VADR transportation awards described below.

Voyager Technologies received $298 million in task orders across two separate south-pole delivery missions, the largest single-day dollar milestone in its history. Voyager, which completed its acquisition of Astrobotic in July 2026, now operates as the prime for Griffin-class landers; their JPL integration work was confirmed in prior TechTimes coverage as recently completed.

ispace-US joins CLPS 2 as a prime contractor after spending its previous NASA relationship as a subcontractor to Draper on the terminated CP-12 task order. That Draper/ispace-US mission — a south-pole delivery — was cancelled when Draper failed to secure a qualified lander. ispace-US now brings its own micro-lander heritage to the table as a named CLPS 2 vendor.

Intuitive Machines holds three communications relay missions under its CLPS 2 task orders — a sensible fit for a company whose Odysseus lander demonstrated the ability to reach the surface and operate, and whose IM-2 Athena lander touched down at the lunar south pole in March 2025, reaching the southernmost lunar landing on record, though the craft tipped on contact.

Firefly Aerospace was awarded three south-pole delivery missions under its task orders, continuing the momentum from its Blue Ghost Mission 1 success in early 2025.

Lockheed Martin Space was awarded a south-pole landing pad preparation mission — an engineering task that prioritizes surface stability assessment over payload delivery, appropriate for the prime that knows ablative re-entry and deep-space systems better than almost anyone.

Northrop Grumman Space Systems holds a south-pole delivery mission consistent with its prior Cygnus-heritage cargo experience.

SpaceX received a Specialized Delivery Mission that will deploy Starship as a cislunar communications demonstration in 2028 — an orbital-scale mission rather than a surface delivery, keeping SpaceX in the CLPS 2 family while leveraging Starship’s size for a task that suits it.

VADR: Building the Cislunar Transportation Economy

Separate from CLPS 2 surface deliveries, NASA awarded six task orders totaling approximately $1.3 billion under the Venture-Class Acquisition of Dedicated and Rideshare (VADR) program to Arrow Science and Technology, Blue Origin, and Impulse Space. These missions are not about landing payloads — they are about building the logistics network that connects Earth orbit to the Moon.

VADR missions fall into three types. Type 1 missions verify navigation and communications on the Earth-to-Moon transit corridor and include CAPSTONE 02, a successor to the 2022 CAPSTONE mission that first demonstrated the Near Rectilinear Halo Orbit intended for the Gateway station. Type 2 missions deploy MoonFall drones — small aerial vehicles that survey south-pole terrain from above, providing site characterization data at scales ground rovers cannot achieve. Type 3 missions demonstrate refuelable, reusable orbit transfer vehicles operating in cislunar space — the tugs and ferry stages that would move cargo between Earth orbit, Gateway, and the lunar surface without requiring a new rocket for each trip.

Launch vehicles for VADR missions include Blue Origin’s New Glenn and Relativity Space’s Terran R for Earth-to-Moon transit legs, with in-space propulsion from Blue Origin, Firefly, Impulse Space, and Quantum Space platforms.

SpaceX Gets a Cislunar Communications Role

SpaceX’s CLPS 2 task order is structurally different from the others. Rather than delivering surface payloads, SpaceX will fly a Starship as a Specialized Delivery Mission in 2028 to demonstrate cislunar communications — a mission that places an orbital relay asset in a configuration that could support both the Moon Base and deep-space missions beyond it.

This is worth noting alongside SpaceX’s Human Landing System contract: SpaceX is simultaneously developing Starship for Artemis III crewed surface landings under a separate Human Landing System contract while also serving as a CLPS 2 vendor for a different mission type. The two programs use the same vehicle family but have different NASA contract lines, different mission parameters, and separate funding streams.

miniCAST: The First Permanent Fixture at the Moon Base Site

Before any lander touches down at the Moon Base site, something needs to be there: power, communications, and a surface reference. That role falls to miniCAST — the Mini-Communications and Solar Tower — a modular infrastructure system built by a team of three companies, each responsible for one functional layer.

Blue Origin’s Honeybee Robotics subsidiary provides the energy storage system. Redwire provides the power generation architecture. Yank Technologies provides the wireless power transfer capability — the ability to beam electrical power across the surface to rovers, landers, or equipment caches without physical connections.

The wireless power transfer element is the least familiar of the three. Yank Technologies’ system uses resonant inductive coupling or radio-frequency energy transfer — the same physical principles behind wireless phone charging, scaled up and adapted for a vacuum environment with no atmosphere to interfere with the transfer medium. At the south pole, where shadowed and illuminated terrain may be interleaved at fine scales, the ability to deliver power to a rover in darkness from a tower in sunlight without running cables across regolith is a meaningful operational advantage.

miniCAST will be the first permanent infrastructure deployed at the Moon Base site. Its operational status will be the prerequisite for most subsequent CLPS 2 surface missions, which will depend on its power relay and communications uplink.

The Prior CLPS Record — Context the New Program Inherits

CLPS 1.0 launched in 2018 with original ambitions and a $2.6 billion ceiling. Its record is instructive for understanding both the promise and the risk of the CLPS 2 model.

Of the missions attempted under CLPS 1.0 through early 2025: Astrobotic’s Peregrine Mission 1 (January 2024) was lost to a propellant leak; Intuitive Machines’ Odysseus (February 2024) landed but tipped on its side; Firefly’s Blue Ghost Mission 1 (early 2025) succeeded and operated as designed. The pattern suggests that the commercial lunar delivery industry is in an early-learning phase consistent with how SpaceX’s early Falcon 9 development looked in 2010–2014 — losses are expensive but not fatal, and each mission feeds forward into the next.

NASA’s deliberate acceptance of this risk — structuring CLPS as delivery payments rather than development cost reimbursement — means the agency pays for success and absorbs mission failure risk on paper. What the government actually absorbs is the science payload investment on lost missions; the lander development cost sits on the vendor’s balance sheet.

CLPS 2 inherits this dynamic at a larger scale and with higher stakes, since several missions now target the actively chosen Moon Base site rather than demonstration locations.

What to Watch Next

PROMISE rover final assembly at JPL (2026–2027): The integration of flight-qualified RTG hardware with the rover chassis will mark the transition from engineering model to flight system. Watch for JPL press briefings on instrument integration.

Blue Origin Mark 1 lander readiness: The Mark 1 is Blue Origin’s smaller lander — different from the Blue Moon Mk2 being developed for Artemis crewed missions. Its flight history to date and schedule to PROMISE delivery certification will be the clearest indicator of whether a 2028 launch is achievable.

VADR Type 3 OTV demonstration: The in-space propulsion demonstrations by Impulse Space and Quantum Space will give the industry its first operational data on reusable cislunar tugs. If those demonstrations succeed on schedule, the Moon Base logistics model gains a critical validated node.

miniCAST deployment timeline: The first element of the Moon Base site’s permanent infrastructure. Its deployment mission has not yet been assigned a launch date; that assignment will effectively set the sequencing clock for all subsequent CLPS 2 surface missions.

CLPS 2 first competitive task order: Beyond today’s initial award to Blue Origin, the remaining $10 billion ceiling will be competed through open solicitations among the eight vendors. The first competitive task order — the design, the evaluation criteria, the award — will reveal how NASA’s procurement office operationalizes the Moon Base priority in dollar terms.

Frequently Asked Questions

What is the PROMISE rover, and what will it do on the Moon?

PROMISE (Polar Rover for Observation, Mapping, and In-Situ Exploration) is a six-wheeled science rover being assembled at NASA’s Jet Propulsion Laboratory from engineering test models and spare flight components left over from the Curiosity and Perseverance Mars missions. It will be delivered to the lunar south pole by Blue Origin around 2028 and spend 18 months operating in and around permanently shadowed craters — the ultra-cold regions that have never seen direct sunlight and preserve ancient deposits of water ice. Its primary instruments include a drill capable of extracting regolith from 1 meter (3.3 feet) below the surface, spectrometers to analyze the volatile content of those samples, and cameras and sensors to characterize the environment for future human missions.

How does a nuclear-powered rover work in a place with no sunlight?

PROMISE carries a Multi-Mission Radioisotope Thermoelectric Generator (MMRTG) — the same type of nuclear power unit that has been keeping Curiosity and Perseverance operating on Mars for over a decade. The MMRTG uses the heat from the natural decay of plutonium-238 to generate electricity through the Seebeck effect: a voltage appears wherever there is a temperature differential across a pair of dissimilar conductors. At one end: the hot radioactive fuel. At the other: the cold side, which in the Moon’s permanently shadowed craters reaches as low as 25 K (−414°F / −248°C). The greater the temperature differential, the more efficient the conversion. PROMISE will draw power more efficiently in its operational environment than Curiosity does on Mars, producing approximately 110 watts of continuous electrical power with no solar input required. This output does not vary with time of day, lunar night, shadow depth, or crater geometry — which is exactly why nuclear power is the only viable option for a rover that must operate inside craters that have been dark for billions of years.

What is CLPS 2, and why does the $10 billion figure matter?

CLPS 2 (Commercial Lunar Payload Services 2) is a 10-year indefinite-delivery, indefinite-quantity (IDIQ) contract that creates a pool of eight pre-qualified vendors who will compete for specific task orders to deliver cargo to the Moon. The $10 billion ceiling is the maximum NASA can spend across all task orders over the life of the contract — not a guarantee that any specific company will receive that amount, or even that the full ceiling will be used. What the ceiling establishes is the scale of the program: NASA has the legal authority and budget structure to spend up to $10 billion on commercial lunar cargo over the next decade. The first specific task order funded under CLPS 2 is the Blue Origin PROMISE rover delivery at $94 million.

Is there really water ice at the lunar south pole?

Yes — multiple missions have confirmed ice at the lunar south pole. The LCROSS impactor in 2009 hit Cabeus crater and created a debris plume that spectrometers detected was rich in water vapor. Chandrayaan-1’s Mini-RF radar and NASA’s Lunar Reconnaissance Orbiter have since mapped extensive surface ice deposits at both poles. Scientific estimates put total polar ice reserves at hundreds of billions of tons. What is not yet confirmed is the form and concentration of that ice at depth — whether it is pure ice that could be efficiently extracted, or ice molecules scattered sparsely through regolith. That is exactly what PROMISE’s drill is designed to determine, and the answer will directly shape the engineering specifications for the Moon Base’s water and propellant production systems.

What happened to the CLPS 1.0 program, and why should CLPS 2 be expected to succeed where some early missions failed?

The original CLPS program (now capped at $4.2 billion, running through 2033) had a genuinely mixed record: Astrobotic’s Peregrine Mission 1 was lost to a propellant leak in January 2024, and Intuitive Machines’ Odysseus reached the surface but tipped on its side. Firefly’s Blue Ghost Mission 1 succeeded in early 2025. NASA’s response to this record has been to increase funding and expand the vendor pool — a signal that the agency views the failures as the expected cost of an early commercial development program rather than evidence that the model is flawed. The CLPS 2 vendor pool includes companies with significantly greater financial and engineering resources than the early CLPS 1.0 participants (Lockheed Martin and Northrop Grumman were not in the original pool), and several missions are now explicitly staged to build on each other’s results rather than operating as standalone demonstrations.
