N.O.V.A.

Giant artificial satellites, known as near-orbitals, were developed as a viable alternative for human habitation after it became clear that the Earth could no longer support life. Near-orbitals joined N.O.V.A., the Near Orbit Vanguard Alliance, to defend themselves better. To save humanity from extinction, the war hero Kal Wardin, who had previously resigned from the Marine Corps, is coerced into returning to active duty against his will.
