MathJax reference. This project was a homework assignment from LaunchCode's Lc101 (2019). Spirit and Opportunity - those little robots scurrying around Mars)." NASA is too conservative to switch to Java, as C (and C++) has proven adequate to the task for 20+ years, since Mars Pathfinder used VXworks/C on the lander software in 1997. Change 'Command type required.' Work fast with our official CLI. Landing on the Red Planet is only the very first step in the life of a Mars rover. Right now, if the provided rover plan results in a collision or out-of-bounds error the program simply omits that rover from the results (assuming it crashed or fell off a cliff).
