Similar to Sub-Orbital Space in most regards, Orbital Space differs in that the craft being launched must circle the Earth at least once at an altitude of no less than 62 miles (100 km) before beginning its descent.
To date, only craft using conventional rocket engines have succeeded in achieving orbit, though an alternative system called a Launch Loop has been proposed, which would operate in a similar fashion to a Mag-Lev train, using electromagnetic track to convey a craft into an orbital trajectory.
Although a craft is said to be in orbital space if the minimum altitude is maintained, crafts that drop below 200 km are subject to atmospheric drag and as such are said to be in unstable orbits, likely to last no longer than a few months, at best. For a craft to remain in orbital space, an altitude ranging from 350 km for Low-Earth Orbit to just under 36,000 km for a Geostationary Orbit.
