NASA's Newest View of the Sun

NASA hosts a news update about the June 26 launch of the Interface Region Imaging Spectrograph (IRIS) mission from Vandenberg Air Force Base in California.

IRIS is a NASA Small Explorer Mission to observe how solar material moves in a dynamic million-degree atmosphere that drives the solar wind around the Sun's atmosphere. The region is the origin of most of the ultraviolet solar emission that impacts the near-Earth space environment and Earth's climate.
