In late June 2013, NASA will launch a new set of eyes to offer the most detailed look ever of the sun’s lower atmosphere, called the interface region. This region is believed to play a crucial role in powering the sun’s dynamic million-degree atmosphere, the corona. The Interface Region Imaging Spectrograph or IRIS mission will provide the best resolution so far of the widest range of temperatures for of the interface region, an area that has historically been difficult to study.
