Image Caption: UARS being deployed with the Shuttle Arm, STS-48, Sept 1991.
UARS is the first in a series of instruments to be deployed
as part of NASAs Mission to Planet Earth. These instruments
will collect data on global phenomena and change, and be
used to generate models to predict future conditions.

(A brief description follows)
UARS - Upper Atmosphere Research Satellite
- Launched September 1991 from STS-48
- Altitude: 600 km circular
- Inclination: 57 deg
- Period:
- Repeat Time:
- Purpose: To provide integrated global measurements
of the chemistry, dynamics, and energetics of the stratosphere, mesosphere, and lower thermosphere. This data will assist in understanding the chemical and physical processes that control the upper atmosphere structure and variability, in understanding the response of the upper atmosphere to natural and human disturbances and to define the role of the upper atmosphere in climate and climate variability.
