Is this the year the U.S. finally lands a robotic rover on the moon?
A hidden milestone lurks in the U.S.’s Artemis-focused lunar ambitions—the nation’s first-ever successful robotic moon rover

NASA has launched four astronauts on a pioneering journey around the moon—the Artemis II mission. Follow our coverage here.
As NASA’s Artemis II mission unfolds, with four astronauts on the first crewed lunar voyage since 1972’s Apollo 17, the U.S.’s elite status as the only nation to ever send humans to the moon remains a point of patriotic pride. Yet in at least one aspect of lunar exploration, the U.S. is a surprising underachiever: it has never successfully deployed and operated a robotic rover on the moon.
That could change this year.
The Soviet Union took pole position in the lunar rover race in 1970 with its Lunokhod 1 mission, the first of two successful Soviet rovers. More recently, China’s ambitious space program has sent two rovers, one of which, Yutu-2, became the first human-made rover to operate on the lunar far side—where it is still working today. India and Japan are members of the lunar rover club, too.

Under the auspices of NASA’s Commercial Lunar Payload Services (CLPS) program, last year one company came close to finally putting the U.S. on the board. Lunar Outpost’s MAPP (Mobile Autonomous Prospecting Platform) rover reached the lunar surface alive and well within a lander built and operated by aerospace firm Intuitive Machines. But, alas, the mothership had landed askew, trapping MAPP inside. (Other mobile robotic payloads onboard—including the Massachusetts Institute of Technology–built AstroAnt, as well as Intuitive Machines’ surface-hopping Micro Nova craft—suffered the same fate.)

Now Intuitive Machines is on track to try again by sending another CLPS lander to the moon in the second half of 2026. This time its payloads include Lunar Vertex, a small rover meant to investigate the mysteries of a “lunar swirl” called Reiner Gamma in a region known as Oceanus Procellarum on the moon’s near side. Three solar-powered mini rovers built by NASA’s Jet Propulsion Laboratory are also onboard that lander. Collectively called CADRE (Cooperative Autonomous Distribution Robotic Exploration), the tiny trio aims to show how multiple networked rovers can work together on the moon. And depending on which of these projects off-loads first, CADRE might steal the “first successful U.S. moon rover” title from Lunar Vertex.
Separately, another CLPS mission for the latter half of this year will see a Griffin lander from Astrobotic that will bring not one but two rovers to the lunar surface—Astrobotic’s own diminutive CubeRover and the hulking, nearly 500-kilogram Flex Lunar Innovation Platform (FLIP) rover from aerospace company Astrolab. This mission will target the south polar region, where companies and countries alike are pursuing the scientific and economic prospects of lunar water ice.
Thus, it’s a four-way race among Lunar Vertex, CADRE, CubeRover and FLIP to be the first-ever American lunar rover to successfully deploy and operate on the moon—assuming, that is, any of them manage to reach the surface. The CLPS program has so far sent four landers to the moon, but only one of those—the rover-free Firefly Blue Ghost Mission 1—has been considered a complete success.
“Wow, it hadn’t occurred to me that Lunar Vertex could be the first U.S. robotic rover to operate on the moon. Seems like a lot of responsibility!” says principal investigator David Blewett of the Johns Hopkins University Applied Physics Laboratory.
“Our rover is based on Lunar Outpost’s MAPP product,” Blewett says, noting that, despite MAPP’s ignominious demise inside the Intuitive Machines lander, it had survived long enough to gather and beam back data. “This provided valuable risk reduction and lessons learned for Lunar Vertex,” he says.
While the Artemis campaign garners most of the attention, rovers will matter immensely for U.S. lunar plans, Blewett believes.
“There will always be a place for robotic rovers
