NASA Books a Ride for Its $400 Million Moon Rover PROMISE
NASA's PROMISE rover will fly to the lunar south pole in late 2028 on Blue Origin's Mark 1 lander, reusing Mars rover hardware for a sub-$400 million nuclear-powered mission.

In brief
- PROMISE targets a late 2028 launch on Blue Moon Mark 1 serial number five, with an 18-month prime mission at the lunar south pole.
- NASA estimates PROMISE will cost under $400 million, including a $94 million base award and $140 million option to Blue Origin.
- The six VADR task orders total approximately $1.3 billion.
- Eight companies — including Blue Origin, SpaceX and Lockheed Martin — became eligible to compete for CLPS 2.0 lunar deliveries.
- A solicitation for fully integrated miniCAST lunar power systems is expected in early 2027.
NASA has booked a late-2028 flight for PROMISE, a nuclear-powered lunar rover it expects to build for under $400 million, and paired the mission with a new push to give Moon surface hardware something it has never had: shared power and communications infrastructure.
The announcement came at the MAX POWER aerospace expo at Kennedy Space Center, delivered by NASA Administrator Jared Isaacman, Moon Base Program Manager Carlos García-Galán, science chief Nicky Fox, and Dayna Ise, acting director of the program's Utility and Infrastructure Office.
PROMISE — the Polar Rover for Observation, Mapping, and In-Situ Exploration — will ride to the lunar south pole on Blue Origin's Blue Moon Mark 1 lander, serial number five, and run an 18-month prime mission.
What does this change for lunar science?
The rover's ancestry is the interesting part. Its electronics, body structure and mobility system start from MAGGIE, the Jet Propulsion Laboratory's Earth-bound test twin of the Curiosity Mars rover, supplemented by flight spares and test-bed parts from both Curiosity and Perseverance. Fox said a review concluded Curiosity itself could keep operating with low risk after donating ground hardware.
A flight-spare radioisotope thermoelectric generator — a nuclear battery that converts heat from decaying plutonium into electricity — will power and warm the rover. The fuel comes from existing stock processed for the Cassini mission, with reduced heat output that still suits PROMISE. That matters at the south pole, where permanently shadowed craters never see sunlight and may hold water ice.
"That allows us to survive the night and to probe permanently shadowed regions near the South Pole using technologies that we've literally learned with our Mars rovers," Fox said.
The instrument list leans heavily on VIPER, the ice-prospecting rover NASA canceled in July 2024 over cost and schedule growth. PROMISE carries copies of VIPER's TRIDENT drill — which will sample down to one meter — plus the MSOLO mass spectrometer, a Near-Infrared Volatiles Spectrometer System, and a Neutron Spectrometer System. Additional payloads include the LAFORGE infrared radiometer, a Radiation Assessment Detector, a laser retroreflector, and a Lunar Dashcam.
García-Galán put the cost below $400 million including surface delivery, with NASA separately announcing a $94 million base award to Blue Origin and a $140 million performance-based option. "This was a project enabled by the fact that we saw the hardware in the garage," he said. The caveat: the sequence depends on the first Mark 1 lander — fully assembled as of August, with cryogenic fuel-loading tests still ahead — actually flying successfully. VIPER itself may follow on the second Mark 1, targeting late 2027.
Who is building the Moon's utilities?
A second project, miniCAST — the Mini-Communications and Solar Tower — will test power generation, storage, wireless charging and communications from a single tower, services that isolated landers cannot provide for each other. Marshall Space Flight Center will integrate industry components.
NASA selected Honeybee Robotics for energy storage, Redwire for power generation, and Yank Technologies for wireless power transfer. Ise described rovers navigating toward a tower by its communications link and recharging through an induction plate on the surface. But these are component awards, not a final design; a separate solicitation for fully integrated power systems is expected in early 2027.
"We have to do all that with almost no human interaction," Ise said of rebuilding terrestrial infrastructure on the Moon.
What else was announced?
NASA also unveiled six VADR launch and orbital-transportation task orders worth roughly $1.3 billion:
- CAPSTONE 2: two spacecraft on Quantum Space's Ranger tug, launched by a SpaceX Falcon 9
- Intuitive Machines communications satellites on an Impulse Space-procured Falcon 9, possibly without a tug
- MoonFall: three JPL hopping drones on Firefly's Elytra tug, launched by Blue Origin's New Glenn
- Two Blue Ring/New Glenn transportation orders, one carrying a communications demonstration
- An Impulse Helios/Terran R high-risk lunar-landing demonstration, payload not yet chosen
Separately, SpaceX will demonstrate long-range communications using Starlink satellites deployed by Starship — a demonstration, NASA stressed, not permanent infrastructure.
Finally, eight companies became eligible to compete for next-generation Commercial Lunar Payload Services deliveries: Blue Origin, Firefly Aerospace, Intuitive Machines, ispace U.S., Lockheed Martin, Northrop Grumman, SpaceX, and Voyager Technologies. Eligibility, not a guaranteed mission. Isaacman framed the broader approach bluntly: NASA is "putting our engineers and technicians alongside theirs, whether they like it or not" to ready industry hardware for flight.
