A new NASA spacecraft called the Solar Dynamics Observatory (SDO) will deliver startling images of the sun with ten times more detail than HDTV. The goal of the mission is to help scientists zoom in on solar activity such as sunspots, solar flares and coronal mass ejections, thus improving forcasts of solar storms. The complete script is available. For more information on the Solar Dynamics Observatory, check out their web site at http://sdo.gsfc.nasa.gov.
