KENNEDY SPACE CENTER, FLA. - In the NASA Spacecraft Hangar AE, the Space Infrared Telescope Facility (SIRTF), which has been returned to the hangar from the launch pad, is uncovered by workers following its arrival. SIRTF will remain in the clean room until it returns to the pad in early August. One of NASA's largest infrared telescopes to be launched, SIRTF will obtain images and spectra by detecting the infrared energy, or heat, radiated by objects in space.
