Part 5/14:
On Mars, humans land safely after decades of planning, planting the first structures on Martian soil. These colonies grow rapidly, featuring labs, habitats, and solar farms. The red planet no longer seems distant; it becomes a second home. Nuclear-electric tugboats become the backbone of logistics, regularly transferring supplies between Earth orbital depots, lunar stations, and Martian bases. Meanwhile, orbiting drones monitor Earth’s environment, capturing space debris to prevent catastrophic collisions, and planetary-defense interceptors stand guard at strategic Lagrange points against asteroid threats.
