On June 27, 2015, NASA's Interface Region Imaging Spectrograph, or IRIS, mission will celebrate its second year in space. IRIS observations have advanced our understanding of what role the interface region, which lies between the sun's photosphere and corona, plays in powering its dynamic million-degree atmosphere and driving the solar wind. Since its first birthday last summer, IRIS data has revealed unexpected complexity in the interface region and investigated the source of the extremely high temperatures of the solar atmosphere, or corona.
