President Obama says he supports same-sex marriage, becoming the first sitting U.S. president to come out in favor of the issue. Host Michel Martin looks at what it means for the November elections, and for an issue that many Americans view in religious or moral terms. Martin speaks with two religion reporters: Sarah Posner of Religion Dispatches and David Brody of the Christian Broadcasting Network.
A mosaic of images taken in January 2012 shows Opportunity's vista north (left) and northeast (right), in an outcrop known as "Greeley Haven," where the rover spent its fifth Martian winter. The image released by NASA is presented in "false color," to make differences in the landscape easier to see.
With the darkest days of the Martian winter now over, NASA took its Opportunity Mars Rover for a drive this week. The rover had been stationary while its solar panels lacked enough sunlight to power its batteries.
The rover's drive Tuesday was a short one: "about 12 feet northwest and downhill," according to NASA. The agency says Opportunity has driven 21.4 miles since it landed on Mars in January of 2004.
