July 1, 2013:  When NASA's Mars rover Opportunity blasted off from Cape Canaveral in 2003, many onlookers expected a relatively short mission.  Landing on Mars is risky business. The Red Planet has a long history of destroying spacecraft that attempt to visit it.  Even if Opportunity did... Read More

June 25, 2013:  More than 10,000 asteroids and comets that can pass near Earth have now been discovered. The 10,000th near-Earth object, asteroid 2013 MZ5, was first detected on the night of June 18, 2013, by the Pan-STARRS-1 telescope, located on the summit of the Haleakala crater on Maui.... Read More

June 24, 2013: Flying low and slow above the pristine terrain of Alaska's North Slope research scientist Charles Miller of NASA's Jet Propulsion Laboratory surveys the white expanse of tundra and permafrost below. On the horizon, a long, dark line appears. His plane draws nearer, and the... Read More

Arctic permafrost soils contain more accumulated carbon than all the human fossil-fuel emissions since 1850 combined. Warming Arctic permafrost, poised to release its own gases into the atmosphere, could be the "sleeping giant" of climate change.
