Freestar Experiment

FREESTAR, which stands for Fast Reaction Experiments Enabling Science Technology Applications and Research, was a payload of six separate experiments on the Space Shuttle Columbia.

It was mounted on a crossbay Hitchhiker Multipurpose Equipment Support Structure in the shuttle's payload bay during the STS-107 flight, which ended with the disintegration of Columbia during re-entry into the Earth's atmosphere. Although data was lost in the re-entry, much of the data collected while in space, such as that from MEIDEX, had already been transmitted to ground stations.
