No Roads in Space — Expanded Edition explores how humans navigate beyond Earth when familiar assumptions collapse.

Space offers no paths, no distance markers, and no built-in sense of direction. Navigation depends on geometry, physics, and disciplined reasoning rather than maps or infrastructure. This expanded edition builds on the original work with new material focused on degraded navigation, uncertainty management, and manual recovery when automated systems fail.

Through clear explanations and worked examples, the book shows how orientation, position, velocity, and even distance can be reconstructed using angular measurement, celestial references, and time evolution. It also introduces the physical foundations of interstellar navigation, examining how distance is inferred using standard candles, pulsars, and natural cosmic structure.

Written for technically curious readers, engineers, and spaceflight enthusiasts, No Roads in Space treats navigation as a human reasoning problem grounded in real physics.

There are no roads in space.

But there is structure — and it can be understood.
