What is TIMED?
TIMED is an acronym for Thermosphere, Ionosphere, Mesosphere, Energetics and
Dynamics. The 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). TIMED is focusing on a portion of this region
located approximately 40-110 miles (60-180 kilometers) above Earth's surface.
The science objective of the TIMED mission is to understand the MLTI region's basic
pressure, temperature and wind that result from the transfer of energy into and out
of this region. This mission is helping scientists gain a better understanding of the
dynamics of this gateway region and its effects on communications, satellite tracking,
spacecraft lifetimes, degradation of spacecraft materials and on spacecraft
reentering Earth's atmosphere.
