Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED)

The Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) mission is studying the influences of the sun and humans on the least explored and understood region of Earth's atmosphere: the Mesosphere and Lower Thermosphere/ Ionosphere (MLTI). The MLTI region is where the sun's energy enters Earth's environment for the first time. The TIMED spacecraft focuses on a portion of the MLTI region located at an altitude of approximately 40-110 miles (60-180 kilometers).
