Here is a screen shot of a program that NASA engineers use to drive the rover that is on Mars!

The quote off of the NASA site says:

This image shows a screenshot from the software used by engineers to roll the Mars Exploration Rover Opportunity off its lander and onto martian soil. Engineers received confirmation that Opportunity's six wheels had touched ground at 3:01 a.m. PST, January 31, 2004, on the seventh martian day, or sol, of the mission. The software simulates the rover's movements, helping to plot a safe course. The virtual 3-D world around the rover is built from images taken by Opportunity's stereo navigation cameras. Regions for which the rover has not yet acquired 3-D data are represented in beige. The rover is approximately 1 meter (3 feet) in front of the lander, facing north.

If you are going to be coding --- this would be the program to code. But man, talk about pressure to not make any coding mistakes! ;)
