Where ; ρ is the ambient atmospheric density and v ∞ is the spacecraft velocity relative to the free stream.; It is shown in [16] that given the ability to vary an initial C b1 , a second ballistic coefficient C b2 , and the time t swap at which the ballistic coefficient is changed from C b1 to C b2 , it is possible to target any point on the Earth with latitude below the orbit inclination ... ................
