The RCA Infrared Imaging Experiment (IRIE) flown January 12-18, 1986, on Shuttle Mission 61C is reported. The infrared camera, which was operated in the 3.5- to 5-μm spectral band, replaced one of the visible CCTV cameras on the Shuttle. The camera employed a 160 x 244 element monolithic platinum-silicide (PtSi) area focal-plane array developed at RCA Laboratories. The array characteristics, camera electronics, optics, and focal plane cooling are summarized. The preplanned scenes for the IRIE are listed. A total of about 2.5 hours of data, including some preplanned scenes and unscheduled operation, were recorded on the first, third, fourth, and fifth days of the mission. Several of the recorded scenes are mentioned specifically in the paper, and a short videotape will be shown at the presenta-tion. Quantitative analysis of the data is in progress.
