A ÀÖ²¥´«Ã½ at Boulder 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.
