Humans live in a deep gravity well - this is our reality. The land, sea and air domains exist with this same gravity well - they make sense to us.

Orbital Defender: A lighthearted introduction to orbital mechanics for budding space professionals. Get behind the controls and protect earth from rogue satellites, international threats, experiments gone wrong, and assist science crews in exploration of the galaxy.
