65 million years ago, the Solar System
According to Nikola Tesla's Mars explosion plan, his fleet of ships, along with Abbott and the others, had to move far from the Sun and hide behind Jupiter or Saturn.
Saturn was farther from the blast site and, naturally, relatively safer. Tesla needed to choose a suitable moon as a base where they could temporarily store genetic material and large computers for the next few decades. He chose Iapetus.
Of all the moons in the Solar System with diameters greater than 500 kilometers, Iapetus was the farthest from its parent planet. Its average distance from Saturn was 3.56 million kilometers, while the farthest average distance of any other large moon was less than 2 million kilometers.
The farther a moon was from its parent planet, the longer its orbital period. Iapetus took 79 days to circle Saturn. After Mars exploded, when the debris reached the Saturn System, Iapetus's slow orbital speed would allow it to remain behind Saturn for relatively longer.
As soon as the ships' safety pods landed on Iapetus, Tesla and Abbott got to work. The aircraft orbiting Iapetus also sent back live footage. Over the past decade or so, unmanned intelligent devices had built a network of pipes stretching more than halfway around the moon's equator.
Maria asked curiously, "Are these pipes, each over a thousand kilometers long and resembling oil pipelines, the 'vascular' Superlight Wave Power Station you mentioned?"
"Strictly speaking, these pipes circling the equator are the ground-based section of the Vascular Superluminal Wave Power Station. One end of the pipeline will connect to an 180,000-kilometer-long Carbon Fiber Tube. A craft at the top will use the centrifugal force at the moon's equator to launch it into space, where it will become the Superlight Wave Power Station," Tesla
