NASA's Has HUGE Plans for Superbowl XLV

"On February 6, 2011," says Chris St. Cyr of the Goddard Space Flight Center, "Super Bowl XLV will be played in Arlington, Texas. And on the same day NASA's two STEREO spacecraft will be 180 degrees apart and will image the entire Sun for the first time in history."
STEREO's station on opposite sides of the Sun solves the problem that has troubled astronomers for centuries: Sunspots can materialize, explode, and regroup in a matter of days, coronal holes open and close, magnetic filaments stretch tight and then explode; a full half of these events are hidden from sight making it nearly impossible to track sunspots or understanding magnetic filaments. But in two years, those skipped pages in reasearch will be filled with more of an understanding of how our Sun affects our world and the rest of the solar systems.
Already, however, the two spacecrafts are beaming back over the horizon images that have researchers and forecasters glued to their monitors. "This is a perspective we've never had before," says STEREO mission scientist Lika Guhathakurta of NASA headquarters. "We're now monitoring more than 270 degrees of solar longitude-that's 3/4ths of the star. After all these years, we're finally getting to see the dark side of the Sun."
