CHIPS (Cosmic Hot Interstellar Plasma Spectrometer, also Explorer 82 or UNEX-2) was a NASA Explorer program satellite. It was launched on 12 January 2003 from Vandenberg Air Force Base aboard a Delta II with the larger satellite ICESat, and had an intended mission duration of one year. CHIPS was the second of NASA's University Explorer (UNEX) mission class. It performed spectroscopy from 90 to 250 Angstrom (9 to 26-nm) extreme ultraviolet (EUV) light.[2]
