IRIS (Interface Region Imaging Spectrograph) - NASA's spacecraft for solar research. Mission within the framework of the Small Explorer program (SMEX) to study the physical properties of the solar limb - the visible edge of the solar disk, the solar chromosphere . A device for the Lockheed Martin Solar and Astrophysics Laboratory (LMSAL) was built . The spacecraft is equipped with a spectrometer , which was created by the LMSAL laboratory, and the telescope of the Smithsonian Astrophysical Observatory . The in-orbit will be controlled by LMSAL and NASA's Ames Research Center .

The research tool of the apparatus is a high-frequency ultraviolet spectrometer , with a frequency of one frame per second, with a spatial resolution of 0.3 angular seconds , and with a spectral resolution in fractions of an angstrom .
NASA announced on June 19, 2009 that the IRIS project was selected to be funded from six research missions for the Small Explorer program (SMEX) [1] , along with the Gravity and Extreme Magnetism SMEX (GEMS) project [2] .
The spacecraft arrived at Vandenberg Air Force Base in California on April 16, 2013 [3] and was successfully launched on June 27, 2013 with the Pegasus XL rocket [4] .
