Collection Item Summary:

These are original flight components for the Ultraviolet Imaging Telescope (UIT), one of the major components of the ASTRO mission that flew twice in space, first on Columbia from 2 - 10 December 1990, and then on Endeavour from 3 to 17 March 1995. UIT is an F/9 Ritchey-Chretien reflecting telescope with a primary mirror 38 cm. in diameter.

UIT and HUT were transferred to the National Air and Space Museum in 2005.
