{author} National Aeronautics and Space Administration {date} 24-Feb-2003 {description} KENNEDY SPACE CENTER, FLA. - The Boeing Delta II rocket, the launch vehicle for the Space Infrared Telescope Facility, stands upright in the launch tower on Launch Complex 17-B, Cape Canaveral Air Force Station. SIRTF will obtain images and spectra by detecting the infrared energy, or heat, radiated by objects in space between wavelengths of 3 and 180 microns (1 micron is one- millionth of a meter). Most of this infrared radiation is blocked by the Earth's atmosphere and cannot be observed from the ground. Consisting of an 0.85-meter telescope and three cryogenically cooled science instruments, SIRTF is one of NASA's largest infrared telescopes to be launched. Its highly sensitive instruments will give a unique view of the Universe and peer into regions of space that are hidden from optical telescopes on the ground or orbiting telescopes such as the Hubble Space Telescope. {highres} 3008 x 2000 {highsize} 881114 {hightype} JPEG {keywords} NASA,KSC,Kennedy Space Center {lowres} 320 x 212 {lowsize} 77727 {lowtype} GIF {mediumres} 1024 x 680 {mediumsize} 129436 {mediumtype} JPEG {number} KSC-03PD-0535 {slideres} 120 x 108 {slidesize} 15500 {slidetype} GIF {tinyres} 100 x 66 {tinysize} 8288 {tinytype} GIF {title} KSC-03PD-0535 {type} Image {end}
