An illustration of the asteroid belt as a dense donut-shaped ring of yellow points with the Sun at the center. The background is black with hints of dark blue in the corners and small white pinprick stars sprinkled throughout. A small illustrated Earth sits to the left of the Sun, and a semi-opaque, cone-like teal triangle extends from Earth toward the right. The cone opens up to a mosaic of a couple dozen small, square-like shapes representing Rubin Observatory’s LSST Camera’s detector area. The mosaic is overlaid onto a portion of the asteroid belt, and each tile represents a camera image that detects a group of asteroids. A thin curved white line begins behind the Sun and swings out around the Earth, tracing the path of a small, not-to-scale spacecraft heading toward the illuminated asteroids, ready for exploration.
