        The Spatial Infrared Imaging Telescope (SPIRIT III) was a 33cm        
        clear-aperture off-axis telecope that contained two focal-plane       
        instruments:  a multispectral high spatial resolution (18') radiometer
        and a six-channel high spectral resolution (R~20cm-1), 2.5 to 28      
        micron Fourier transform spectrometer.  The radiometer had four broad 
        spectral bands (A, C, D, and E) and two narrow bands (B1 and B2) that 
        collectively spanned the range from 4.2 to 26 microns.  SPIRIT III    
        flew on the Midcourse Space Experiment (MSX) satellite which was      
        launched in April 1996, and operated until February 1997 when it ran  
        out of cryogen.
