Interface Region Imaging Spectrograph (IRIS)

720403main_iris_logo_full.jpg MISSION SUMMARY
Mission: Interface Region Imaging Spectrograph
Mission type: Solar observations, space weather
Launch date: June 2013
Launch vehicle: Pegasus XL
Launch site: Vandenberg Air Force Base, CA
Mission duration: 2 years (nominal)
Orbit location: Sun-synchronous orbit from a 596 by 666 Km orbit at an inclination of 97.91 degrees and a period of 97.3 minutes.
Status: Pre-launch
Overview: IRIS mission will study the interface between the photosphere and corona by tracing the flow of energy and plasma through the chromosphere and transition region into the corona using spectrometry and imaging. IRIS is designed to provide new information to increase our understanding of energy transport into the corona and solar wind and provide an archetype for all stellar atmospheres. IRIS will provide key insights into all these processes, and thereby advance our understanding of the solar drivers of space weather from the corona to the far heliosphere, by combining high-resolution imaging and spectroscopy for the entire chromosphere and adjacent regions.

The three major interior zones are the core (the innermost part of the Sun where energy is generated by nuclear reactions), the radiative zone (where energy travels outward by radiation through about 70% of the Sun), and the convection zone (in which convection currents circulate the Sun's energy to the surface).
