Astronauts Steven A. Hawley (left) and Michel Tognini are pictured with the Southwest Ultraviolet Imaging System (SWUIS) on Columbia's middeck. SWUIS is an innovative telescope/charge-coupled device (CCD) camera system that operates from inside the shuttle cabin. SWUIS will be used during the STS-93 mission to image planets and other solar system bodies in order to explore their atmospheres and surfaces in ultraviolet (UV) region of the spectrum, which astronomers value for diagnostic value.
