Light Minutes: the solar system with the clock running

Why it surfaced

Light Minutes replaces the usual misleading poster distances with a clock: sunlight is eight minutes old, Saturn is about an hour and a quarter behind, and Voyager is most of a day away. Its three instruments cover a scrollable solar-system map, a walk across Mercury, and the Cassini mission from launch to its final signal.
