A few suggestions:
A better editor for this feedback text. This one is a pain in the *ss. What about for a new row ?
A compass for the rover so you don't have to get in and out of the seat to see where you are heading.
A built in scanner in the rover for finding water and minerals for the same reason as the compass. Since all rocks looks the same it is annoying to find a mineral with the hand scanner and then try to drive the rover to the right rock without having to get in and out of the seat to scan by hand and then drive..
