The Jewel

There are pioneers here if you can find them. They survey on Iapetus in the Saturnian system. They pick and probe, uncover and unearth. They build.

Bonestell's Saturn from 1949's The Conquest of Space, is the right size- about the size of Earth in our Moon's sky. The difference is distance- Iapetus is 10x further from Saturn than the Moon is from Earth!
