Overview of Hyperion on-orbit instrument performance, stability, and artifacts

Hyperion, one of three payloads on the Earth-Observing 1 (EO-1) spacecraft that was launched from Vandenberg Air Force Base on November 21, 2000, is a hyperspectral imager built by TRW Space & Electronics for NASA's Goddard Space Flight Center. EO-1 is part of NASA's New Millennium Program whose goal is to demonstrate advanced technologies for reducing cost and improving quality of instruments and spacecraft for future space missions. Under this program, missions are intended primarily to validate new technologies in-flight and to provide useful data to the scientific research community. The first four months of mission life were focused on instrument activation, functional checkout, and performance verification. This paper presents an overview of the Hyperion instrument, summarize the on-orbit performance verification and validation activities, and describe known instrument artifacts.
