[PAR] [TLE] Mesosphere [SEP] The mesosphere ( ; from Greek "mesos" "middle" and "sphaira" "sphere") is the layer of the Earth's atmosphere that is directly above the stratosphere and directly below the mesopause.  In the mesosphere, temperature decreases as the altitude increases.  The upper boundary of the mesosphere is the mesopause, which can be the coldest naturally occurring place on Earth with temperatures below -143 C .  The exact upper and lower boundaries of the mesosphere vary with latitude and with season, but the lower boundary of the mesosphere is usually located at heights of about 50 km above the Earth's surface and the mesopause is usually at heights near 100 km , except at middle and high latitudes in summer where it descends to heights of about 85 km . [PAR] [TLE] TIMED [SEP] The TIMED (Thermosphere Ionosphere Mesosphere Energetics and Dynamics) is an orbiter mission dedicated to study the dynamics of the Mesosphere and Lower Thermosphere (MLT) portion of the Earth's atmosphere.  The mission was launched from Vandenberg Air Force Base in California on December 7, 2001 aboard a Delta II rocket launch vehicle.  The project is sponsored and managed by NASA, while the spacecraft was designed and assembled by the Applied Physics Laboratory at Johns Hopkins University.  The mission has been extended several times, and has now collected data over an entire solar cycle, which helps in its goal to differentiate the Sun's effects on the atmosphere from other effects.
