What is a space wave?

Explanation:
Space waves propagate through space rather than along the Earth's surface. They travel in straight lines, so their path does not follow the curvature of the ground. This is exactly what the statement describes. Ground waves stay tied to the surface, while waves that bounce off the ionosphere (sky waves) use a different mechanism for long-distance reach, and a wave absorbed by the atmosphere wouldn’t propagate effectively at all.
