A 10-book series by Paul G. de Jong

Astronomy's Shocking Twist

Humanity's path from first orbital infrastructure to interstellar travel — five technical books on the engineering, and five hard science fiction novels that live inside the physics. Known laws. Real materials. Normal lifespans. No shortcuts.

Technical Books

Five books on the engineering.

Orbital rings, mass drivers, space elevators, propulsion, habitats, generational ships. Rigorous but accessible — math kept as straightforward as possible.

Science Fiction

Five novels, eight hundred years.

The human story of building space infrastructure, constrained by the same physics as the technical books. Propulsion limited by power. Materials limited by manufacturing.
