Artist's impression of autonomous rovers exploring a lava tube

In this artist's impression, autonomous rovers, deployed by a "mother" rover, place miniature sensors that allow them to monitor their environment and location as they investigate a lava tube. The sensors act like "breadcrumbs," connecting the rovers to each other while they deploy communication nodes along the way.
