Members of NASA's CADRE (Cooperative Autonomous Distributed Robotic Exploration) technology demonstration team pose with two full-scale development model rovers in the Mars Yard at the agency's Jet Propulsion Laboratory in Southern California in January 2024. The project is designed to show that a group of robotic spacecraft can work together as a team to accomplish tasks and record data autonomously – without explicit commands from mission controllers on Earth. Three small rovers will ride aboard a lunar lander that will carry the project's base station and camera assembly. The rovers shown here are similar in size and appearance to the flight models that will travel to the Moon. Equipped with flight software and autonomy capabilities, these development models were used in a series of Mars Yard tests that helped confirm CADRE hardware and software can work together to accomplish key goals for the project. https://photojournal.jpl.nasa.gov/catalog/PIA26170
