I was working at JPL when the first Rover landed. Once the cameras were turned on, they looked around and took notes. Then they built 2 or 3 settings to mimic the landing area, right down to the color and size of the grain of the sand and rocks. Sun angle was also thrown in. They hand copycat machines they would practice the future movements of the machine, right down to the delay because of the distance for the signal. I will never forget those rooms and practicing done by one of the operators, he had the first man bun I had ever seen.
