It's About TIMED!
News story originally written on December 14, 2001

The TIMED spacecraft was launched onboard a Delta II rocket on December 7, 2001, from Vandenberg Air Force Base in California. The launch went smoothly and TIMED is now in orbit around Earth. Right now, the spacecraft's instruments are being turned on. So far, all systems are nominal and science operations are expected to begin in early January.

During its 2-year mission, TIMED (Thermosphere-Ionosphere-Mesosphere-Energetics and Dynamics) will complete a global study of a region of the atmosphere called the MLTI region. MTLI stands for the Mesosphere and Lower Thermosphere/Ionosphere. This region of the atmosphere is not well understood. It is however vital to understand the MLTI region in order to fully understand what effect the Sun and humans have on the atmosphere, and how these effects trigger global change on Earth.

It is also important to understand this region, because many of our communication satellites orbit the Earth in this region. By better understanding the MLTI region, we'll better understand spacecraft lifetimes in that region, degradation of spacecraft materials, and how satellites in this region would reenter through the Earth's atmosphere.

The TIMED mission is the initial mission of NASA's Solar-Terrestrial Probes Program (STP).
