This artist rendering released by IMCCE (Institut de Mecanique Celeste et de Calcul des Ephemerides) shows water plumes spewing from the surface of the dwarf planet Ceres. Scientists led by the European Space Agency observed the plumes and reported their findings in the Jan. 23, 2014 issue of the journal Nature. (AP Photo/ IMCCE, Paris Observatory, CNRS)

Riley Duren, the chief systems engineer for the Earth Science and Technology Directorate at NASA's Jet Propulsion Laboratory(JPL), shows the global map of carbon dioxide at Mount Wilson, Calif., Friday, April 12, 2013. A mile above this city, sensors gaze down on the basin from atop Mount Wilson the way a satellite fixates on Earth, collecting pieces of information about Los Angeles' carbon footprint.

This image provided by NASA and taken by a camera aboard NASA's Mars Reconnaissance Orbiter shows the equatorial plains region known as Elysium Planitia on Mars. Using a radar instrument aboard the spacecraft, scientists made a 3-D map of flood channels below the surface of Mars, apparently created by past flooding. The findings were reported online Thursday, March 7, 2013 in the journal Science. (AP Photo/NASA)

FILE - This Dec. 12, 2012 file image provided by NASA shows the Mars rover Curiosity at a pit stop, a shallow depression called "Yellowknife Bay." It took the image on the 125th Martian day, or sol, of the mission (Dec. 12, 2012), just after finishing that sol's drive. The Sol 125 drive entered Yellowknife Bay and covered about 86 feet (26.1 meters). The descent into the basin crossed a step about 2 feet (half a meter) high, visible in the upper half of this image. Curiosity will now head for Mount Sharp in mid-February after it drills into its first rock. (AP Photo/NASA/JPL-Caltech, File)
