This artist's scoreboard displays a fictional game between Mars and Earth, with Mars in the lead. It refers to the success rate of sending missions to Mars, both as orbiters and landers. Of the previous 39 missions targeted for Mars from around the world, 15 have been successes and 24 failures. For baseball fans, that's a batting average of .385. The United States has had 13 successes out of 18 attempts, or a “batting average” of .722. NASA's Curiosity rover, set to land on the Red Planet the evening of Aug. 5, 2012 PDT (morning of Aug. 6 EDT), will mark the United States' 19th attempt to tackle the challenge of Mars, and the world's 40th attempt.

A federal judge in December 2013 formally declared the city bankrupt but it won court approval to exit bankruptcy last November. Once the proud symbol of U.S. industrial strength, Detroit fell on hard times after decades of population loss, rampant debt and financial mismanagement left it struggling to provide basic services to residents.
