This image provided by NASA shows an image captured by NASA’s Solar Dynamics Observatory of a blast of plasma streaming from the sun in August 2012. Scientists say a solar eruption was detected on March 5, 2013 and was headed toward Mars. NASA’s Curiosity rover will postpone some activities but other Mars missions will operate normally.(AP Photo/NASA)

This composite image made available by NASA and assembled by data acquired from the Suomi NPP satellite in April and October 2012 uses the satellite’s Visible Infrared Imaging Radiometer Suite (VIIRS), to show the U.S's lights at night. Americans are paying more to maintain the nation's electrical grid than a decade ago, but they appear to be getting little for their money from utility services that are no more reliable and in some cases seem to be getting worse. An Associated Press analysis of utility spending and reliability nationwide found that electric customers are spending 43 percent more than they did in 2002 to build and maintain local electric infrastructure. Since then, power outages have remained infrequent; but when the lights do go out, it now takes longer to get them back on. (AP Photo/NASA)

This artist rendering provided by NASA shows the Van Allen radiation belts around Earth. A new study published Thursday Feb. 28, 2013, in the journal Science reports that NASA’s recently launched twin satellites to the region discovered a third, temporary ring. It appeared for a month before a shock wave from the sun destroyed it. Scientists are still trying to figure out how often this happens. (AP Photo/NASA)

This undated image provided by NASA shows powdered rock in the scoop of the Mars rover Curiosity. The six-wheel rover collected the sample after drilling into a Martian rock. The next step is to transfer a portion to its onboard laboratories for analysis. Curiosity landed in August 2012 to study whether the environment was hospitable for microbes. (AP Photo/NASA)

The passage of asteroid 2012 DA14 through the Earth-moon system, is depicted in this handout image from NASA. On February 15, 2013, an asteroid, 150 feet (45 meters) in diameter will pass close, but safely, by Earth. The flyby creates a unique opportunity for researchers to observe and learn more about asteroids. REUTERS/NASA/JPL-Caltech/Handout
