Due to the speed of light being the speed of communication between earth and for example, Philae's lander, how is it possible to control it to a safe landing, without crashing, if your vision is ~1000 seconds behind real time?

You don't try to do it live, you pre-program maneuvers using advanced computer models and mathematical predictions.  This is part of what makes the landing so exciting from an engineering and technology standpoint.
