NASA's IRIS readies for a new challenge

NASA is getting ready to launch a new mission, a mission to observe a mysterious region of the solar atmosphere that may be crucial to understanding what powers space weather.

In late June 2013, the Interface Region Imaging Spectrograph, or IRIS, will launch from Vandenberg Air Force Base, Calif. IRIS will tease out the rules governing the lowest layers of the solar atmosphere -- historically some of the hardest to untangle. Known as the solar interface region, this is one of the most complex areas in the sun's atmosphere: all the energy that drives solar activity travels through it.

The interface region lies between the sun’s 6,000-degree, white-hot, visible surface, the photosphere, and the much hotter multi-million-degree upper corona.
