Method of protecting a planetary rover vehicle, that travels in a manner that is at least partially autonomous, against an exterior environment that has become hostile wherein the vehicle takes shelter and emerges from shelter against the exterior environment of its own accord, respectively in response to first and second events delimiting a period in which the exterior environment is hostile. The vehicle is therefore isolated from the exterior environment during this period.
