Space does not offer directions. There are no highways between planets, no signs to follow, and no GPS to guide the way. Yet spacecraft routinely travel millions of kilometers and arrive at their destinations with astonishing precision. No Roads in Space explains how that is possible — in plain language, without heavy math or technical jargon. This book explores how motion works when there is no friction, how gravity shapes every path through the solar system, and how timing and prediction matter more than steering. From orbital mechanics to gravity assists and autonomous navigation, the journey reveals that spaceflight is less about control and more about understanding motion itself. Written for curious readers rather than specialists, No Roads in Space offers a clear and intuitive look at how humans navigate the largest terrain we have ever explored — when there are no roads at all.
