Landsat Satellite To Begin Study Of Earth

NASA is set to launch a satellite this morning that will study the Earth.  The Landsat Data Continuity Mission is a 40-year study of the Earth's surface. 

It's a joint mission with the U.S. Geological Survey, aimed at better understanding deforestation, the retreat of glaciers, the shrinking Antarctic ice sheet, increasing wildfires and other changes around the world. 

If weather permits, the launch from Vandenberg Air Force Base in Southern California will go off today between 10:02 and 10:50 a.m.
