Orbital Ring Engineering, Volume I Pre-order

Space Mass Transit Complete Design Review

Orbital rings? Mass drivers? Space elevators? This book has the numbers.

An orbital ring is a cable in orbit around the Earth, moving faster than orbital velocity, with a stationary casing riding on it. Anchor lines tie it to the ground, a mass driver on the ring throws spacecraft to the Moon, Mars and beyond, and space elevators bring people home. No rockets, no fuel, no countdown. Volume I is the complete design review: one ring, one design, every number checked and every one of them open to inspection.

The author

About Paul G. de Jong

Paul G. de Jong, author of Orbital Ring Engineering

Paul G. de Jong writes at the intersection of physics, electronics and engineering, with three decades of work in medical ultrasound, hydrogen energy, software, audio and a home physics lab. Orbital Ring Engineering is his three-volume engineering treatment of space mass transit infrastructure: orbital rings, mass drivers and space elevators. His threshold for suspension of disbelief is very low, and the technical series arose from a desire for more truly hard science fiction.

What Paul G. de Jong writes

Engineering textbooks and hard science fiction, built on the same physics.

Astronomy's Shocking Twist is a ten-book project. Five technical books on the engineering of space mass transit, written to serve as undergraduate textbooks, and five hard science fiction novels set in the world those books describe. Known laws. Real materials. Normal lifespans. No shortcuts.

Astronomy's Shocking Twist

Technical works

These books are the scientific background behind the Astronomy's Shocking Twist series.

Astronomy's Shocking Twist

Hard science fiction

Five novels over eight hundred years. Hard science fiction in the strictest sense: every law of physics is obeyed as currently understood. The titles follow the story outline and are not final.
