sts-45

The objective of the ALAE experiment is to measure atomic hydrogen and deuterium in the terrestrial atmosphere. The instrument consists of a spectrophotometer with an atomic hydrogen absorption cell and an atomic deuterium absorption cell. Various combinations of switching the cells on and off allow observations of the atmospheric deuterium layer, the atomic geocorona, and the Lyman-alpha interplanetary medium. STS-45

STS-45 was a 1992 spaceflight using Space Shuttle Atlantis. Its almost nine day scientific mission was with a non-deployable payload of instruments.

Carried first Atmospheric Laboratory for Applications and Science (ATLAS-1) on Spacelab pallets mounted in orbiter's cargo bay. The non-deployable payload, equipped with 12 instruments from the United States, France, Germany, Belgium, Switzerland, The Netherlands and Japan, conducted studies in atmospheric chemistry, solar radiation, space plasma physics and ultraviolet astronomy. ATLAS-1 instruments were: Atmospheric Trace Molecule Spectroscopy (ATMOS); Grille Spectrometer; Millimeter Wave Atmospheric Sounder (MAS); Imaging Spectrometric Observatory (ISO); Atmospheric Lyman-Alpha Emissions (ALAE); Atmospheric Emissions Photometric Imager (AEPI); Space Experiments with Particle Accelerators (SEPAC); Active Cavity Radiometer (ACR); Measurement of Solar Constant (SOLCON); Solar Spectrum (SOLSPEC); Solar Ultraviolet Spectral Irradiance Monitor (SUSIM); and Far Ultraviolet Space Telescope (FAUST). Other payloads included Shuttle Solar Backscatter Ultraviolet (SSBUV) experiment, one Get Away Special (GAS) experiment and six mid-deck experiments.

This Randy Hunt replica patch features the crew line up with Dr. Michael Lampton. Lampton was replaced by backup payload specialist Dirk Frimout from Belgium due to medical problems.

Payload on STS STS-45 STS-50 STS-65 (USML)

The objective of the Atmospheric Emissions Photometric Imaging (AEPI)
experiment was the investigation of the upper atmosphere-ionosphere
and the space shuttle environment. The AEPI experiment was flown on
the Space Shuttle as part of the Atmospheric Laboratory for
Applications and Science (ATLAS 1).
