About
The Space Infrared Telescope Facility (SIRTF) arrived at Building AE today to begin final preparations for its launch aboard a Delta II rocket. The observatory was shipped to Florida from the Lockheed Martin plant in Sunnyvale, Calif. 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 highl — NASA KSC · 2003.
