Mars rover – A rover is moving on the surface of Mars. The soft landing of the rovers is carried out with the help of the descent vehicles.
Unlike the rover, the rover does not have the ability to remotely control the commands of an operator who is on Earth in real time due to the fact that the signals from the rover and the command signals from the rover have significant differences in speed. The delay time, depending on the relative position of Earth and Mars, ranges from 3 minutes 6 seconds to 22 minutes 17 seconds. A delay occurs when a radio signal, due to its limited propagation, takes some time to reach Mars and then reach Earth. Rovers can function for some time, including moving and performing research, independently according to pre-designed programs, receiving commands only for a while.
