KENNEDY SPACE CENTER, FLA. - The Space Infrared Telescope Facility (SIRTF) is rolled out of the hangar at Cape Canaveral Air Force Station during pre-dawn hours. It is being transported to Launch Pad 17-B where it will be lifted into the mobile service tower and prepared for launch. SIRTF consists of three cryogenically cooled science instruments and an 0.85-meter telescope, and is one of NASA’s largest infrared telescopes to be launched. It is the fourth and final element in NASA’s family of orbiting “Great Observatories.” SIRTF will obtain images and spectra by detecting the infrared energy, or heat, radiated by objects in space. Most of this infrared radiation is blocked by the Earth's atmosphere and cannot be observed from the ground.

KENNEDY SPACE CENTER, FLA. - Workers on the mobile service tower on Launch Pad 17-B, Cape Canaveral Air Force Station, wait for the Space Infrared Telescope Facility (SIRTF) to reach their level. SIRTF will be attached to the Delta II rocket and encapsulated in its fairing before launch.
