A University of Colorado at ºù«ÍÞÊÓƵ experiment designed to gather precise data on the sun's ultraviolet output and the response of Earth's upper atmosphere to solar radiation is slated to be launched aboard a NASA spacecraft on Dec. 7. The Solar Extreme Ultraviolet Experiment, or SEE, is one of four instruments on NASA's Thermosphere-Ionosphere-Mesosphere-Energetics-Dynamics, or TIMED, spacecraft. TIMED is scheduled to be launched aboard a Delta vehicle from Vandenberg Air Force Base, Calif., for a planned two-year mission.
