Different orbital regimes (Low Earth Orbit, Medium Earth Orbit, Geosynchronous Orbit, and Highly Elliptical Orbits) are expected to influence the way in which debris is tracked and removed (deorbited), and the length of time to execute the removal task.

It takes a Space Shuttle in low Earth orbit some 90 minutes to complete one Earth orbit.

Low Earth Orbit takes about 90 minutes to complete an orbit.

The inventions relate to space transportation means and to methods for delivering cargoes into a near-earth orbit.

The disclosure can provide for delivery of the payload at a terrestrial location, an Earth orbital location, or an extraorbital location.
