In 2070, as the first Mercury renovation engineering ship arrived at Mercury, 71-year-old Carrie Thomas ended her thirty-year wanderings and finally returned home.
But she came back this time to go even further.
Carrie told Harrison that she wanted to take part in the latest Saturn's Moon Titan Colonization Plan.
Harrison would establish a bridgehead base on Titan, with multiple capabilities such as scientific research, production, and manufacturing, just like the former Titan Research Institute.
At present, Titan Base is the largest human settlement farthest from Earth.
According to the plan, the first mass-energy conversion equipment will be completed on Titan in eighty years.
By 2200, the first-generation Dyson membrane, located between the orbits of Uranus and Neptune, will be built by workers from the Titan Base.
Before 2250, the first Ambitious Voyager bound for Proxima Centauri will set sail.
