Last Mission STS-43
Next Mission STS-44
- Primary payload, the Upper Atmosphere Research Satellite
(UARS), deployed on the third day of the mission. During its
planned 18-month mission, the l4,500-pound observatory will
make the most extensive study ever conducted of the Earth's
troposphere, the upper level of the planet's envelope of life-
sustaining gases which also include the protective ozone layer.
UARS has ten sensing and measuring devices: Cryogenic Limb
Array Etalon Spectrometer (CLAES); Improved Stratospheric and
Mesospheric Sounder (ISAMS); Microwave Limb Sounder (MLS);
Halogen Occultation Experiment (HALOE); High Resolution Doppler
Imager (HRDI); Wind Imaging Interferometer (WlNDII); Solar
Ultraviolet Spectral Irradiance Monitor (SUSIM); Solar/Stellar Irra-
diance Comparison Experiment (SOLSTICE); Particle Environ-
ment Monitor (PEM) and Active Cavity Radiometer Irradiance
Monitor (ACRIM II).
- Secondary payloads were: Ascent Particle Monitor (APM);
Middeck 0-Gravity Dynamics Experiment (MODE); Shuttle Activation
Monitor (SAM); Cosmic Ray Effects and Activation Monitor (CREAM);
Physiological and Anatomical Rodent Experiment (PARE); Protein Crystal
Growth II-2 (PCG II-2); Investigations into Polymer Membrane Processing
(IPMP); and the Air Force Maui Optical Site (AMOS) experiment.
