If sending data on earth from mars takes e.g 10 min then how do NASA scientists manage to synchronize stuff with Mars rovers ?
Suppose if something goes wrong and it is required to control or guide a rover (from Earth) to perform some immediate tasks to protect itself. So from Earth instructions are sent but it reaches the rover 10 min. later and in those 10 minutes the rover has performed some other actions (which might not be enough to protect itself). So while these things need to be in sync. there should be some technologies or ways to achieve this.
