Summary

The IRIS satellite, officially designated as 2013-033A and cataloged under NORAD ID 39197, was launched on June 28, 2013, from the Wallops Flight Facility (WRAS) using a Pegasus XL launch vehicle. With dimensions of 2.1 meters in length and 1 meter in diameter, IRIS has a span of 3.7 meters and weighs approximately 183 kilograms both at launch and dry mass. It is equipped with a 20 cm UV telescope integrated with a multi-channel imaging spectrograph for particle imaging missions. The satellite's power system includes two deployable fixed solar arrays and batteries, while its shape is characterized as Hex+Cyl+2 pan with an RCS of 1.318 square meters. Managed by ARC/GSFC, IRIS was designed to operate for a period of 2 years post-launch.
