.:: The SABER Mission
Understanding current atmospheric processes will enable more accurate prediction of future changes in order to assess the consequences as well as suggest corrective solutions for society. The NASA instrument called SABER will allow researchers to learn more about the upper atmosphere by helping produce the first comprehensive global measurements of Earth's upper atmosphere (60 to 100 km range - upper mesosphere & ionosphere). It is one of four instruments on the TIMED (Thermosphere, Ionosphere, Mesosphere, Energetics and Dynamics) spacecraft. SABER will view & measure the vertical distribution of infrared radiation emitted by various atmospheric gases (ozone, water vapor, nitrogen, and carbon dioxide) & provide measurements of the temperature and chemical structure of the atmospheric limb adding important information to what is known as the radiation budget.

.:: Mission Goals
1) To understand the influence of the Sun and lower atmospheric weather on Earth's upper atmosphere.
.........Short-term variability caused by the sun from above and the weather from below.

2) To understand the influence of human activities on Earth's atmosphere.
.........Long-term variability caused by human activities from below.

.:: Mission Objectives
1) To Determine the MLTI Basic Structure:
To determine the temperature, density, and wind structure in the Mesosphere, Lower thermosphere, and Ionosphere (MLTI) region (60-180 km), including the seasonal and latitudinal variations;

2) To understand the MLTI Energy Balance:
To determine the relative importance of the various radiative, chemical, electrodynamical, and dynamical sources and sinks of energy for the thermal structure of the MLTI region.

.:: Scientific Rationale
"The Earth's mesosphere and lower thermosphere are the least explored region on the Earth's atmosphere. They are influenced by varying solar extreme ultraviolet, ultraviolet, and X-ray radiation, auroral particles and fields, and upward propagating waves and tides from the lower atmosphere.... It is known that the global structure of this region of the atmosphere can be perturbed during stratospheric warmings and solar-terrestrial events (magnetospheric substorms, solar flares), but the overall structure and dynamics responses of these effects...are not understood."
