Rover-Mounted vs Astronaut-Carried EchoQuilt Configurations

A CADRE-class rover carries a different EchoQuilt than an Artemis astronaut does. The sensor count, the power draw, the alignment tolerances, and the patch rate all change with platform. This post walks through the two configurations side by side, quantifies the quilt-fidelity tradeoff, and explains why many analog campaigns now run both platforms in a single traverse rather than picking one.

A JPL concept team planning a lunar lava tube mission at NIAC Phase II typically hits a fork in the decision tree: commit to a rover-carried sensor suite (distributed, autonomous, persistent) or a crew-carried one (high dexterity, short duration, curated placements). The answer has historically been "rover" for cave missions because human presence inside a subsurface void is expensive and rare, and the science return per crew-hour has been hard to justify against the alternative of multiple sols of robotic operation. That logic is changing as Artemis-era surface architecture treats EVAs as a sustained capability rather than an Apollo-style burst, and concept teams now have to answer the platform question with a more nuanced framework than the historical default. JPL's CADRE mission overview describes carry-on-bag-sized rovers mapping lunar subsurface in 3D, and CMU's Robotics Institute cave payload work keeps advancing rover autonomy for pit and lava tube entries.
