The Cooperative Autonomous Distributed Robotic Exploration mission, or CADRE, will land on the side of the moon facing Earth as part of NASA's IM-3 launch, planned for late 2026.
These rovers will spend roughly two weeks mapping the terrain as a self-guided team. No joystick will control them, and no human will approve each turn. The rovers will elect a leader among themselves, assign their own tasks and redraw their plans as a group when one of them runs low on charge.
If it succeeds, CADRE will be the first time NASA has operated multiple rovers beyond Earth as a single autonomous system. That achievement will matter well beyond this mission because NASA is scoping out future missions to the lunar South Pole, where water in the form of ice sits locked in craters that haven't seen sunlight in billions of years. If researchers can chemically split that ice apart and turn it into propellant and breathable air, it could become the feedstock for a lunar economy built around fuel depots and life support made on the moon.
Right now, the only demand for that ice comes from government contracts. An operation that must be babysat from 239,000 miles (384,000 kilometers) away will not easily scale into a market. So, while a full-blown lunar economy is still far off, CADRE is testing whether robots can work unsupervised long enough, and in enough numbers, to keep a lunar operation running month after month.
I'm an aerospace engineering Ph.D. candidate researching guidance, navigation and control for spacecraft in-orbit servicing and active debris removal. I work on the same problem these rovers face: how a machine decides what to do next when it cannot call home for instructions. At the moon's South Pole, the terrain itself can cause communication disruptions.
Commands reach a rover by way of relay satellites, and crater rims can block the line of sight to those relays. A rover that ventures down into a shadowed crater may lose contact for its entire trip. Spotty communication doesn't just make driving annoying.
