In this lecture Ir. R. Noomen talks about eclipses and maneuvers.  Eclipses, being the time a satellite spends in the shadow of earth, have different effects on a satellite, such as on its power, thermal control and attitude control. The second part covers maneuvers, a change in velocity in order to obtain a change in orbit. The different applications to this are orbit transfers, orbit maintenance, rendezvous and docking, and end of life disposal.
