The Mars Rover recently hit its 4th anniversary of exploration (in Terrestrial years, not Martian) and to celebrate NASA has released the Mars Rover Game for mobile devices or the desktop. The game is both free and fun, and the game page also gives you some comparisons between the game rover and the real one on the red planet. Also on the page are links to information on the other rovers, Curiosity, Spirit, Opportunity, and the as yet unnamed rover mission of 2020. The robots are not the only ones planned to go there; NASA is working on the Journey to Mars project, shooting for a manned landing in the 2030s.
