The Hitchhiker Program (HH) was a NASA program established in 1984 and administered by the Goddard Space Flight Center (GSFC) and the Marshall Space Flight Center (MSFC). The program was designed to allow low-cost and quick reactive experiments to be placed on board the Space Shuttle. The program was discontinued after the failure of STS-107.

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).
