- NASA's Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics (TIMED) spacecraft was launched on December 7, 2001 from Vandenberg AFB. The spacecraft was built by The Johns Hopkins University Applied Physics Laboratory (APL) and shares the same launch vehicle as NASA's Jason-1 spacecraft. TIMED is the first mission in NASA's Solar Terrestrial Probes Program and will study the influences of the sun and humans on the mesosphere and Lower Thermosphere/Ionosphere (MLTI). TIMED will focus on a portion of the atmosphere between 60-180 km above the surface. TIMED's payload consists of four instruments: - Global Ultraviolet Imager (GUVI): a spatial scanning ultraviolet spectrograph designed to measure the composition and temperature profiles of the MLTI region, as well as its auroral energy inputs. - Solar Extreme Ultraviolet Experiment (SEE): comprised of a spectrometer and a suite of photometers designed to measure the solar soft X-ray, extreme ultraviolet and far-ultraviolet radiation in the MLTI region. - TIMED Doppler Interferometer (TIDI): designed to measure the wind and temperature profiles of the MLTI region. - Sounding of the Atmosphere using Broadband Emission Radiometry (SABER): designed to measure the pressure, temperature, key gases in the oxygen and hydrogen families, infrared cooling, and effects of solar and chemical heating of the MLTI region. TIMED is sponsored by NASA's Office of Space Science and is managed by NASA's Goddard Space Flight Center's Solar Terrestrial Probes program Office. The Johns Hopkins Applied Physics Laboratory operates the spacecraft and leads the science effort.
