Introduction
The Spitzer Space Telescope was the first earth to an orbiting telescope, at a cost of $8 billion, formerly the Space Infrared Telescope Facility (SIRTF), December 2003, through a public contest, in which the satellite space telescope to the concept of author, American astronomer Lyman Spitzer, Jr. (William Lyman Spitzer, Lyman Spitzer, Jr. named it plans in space five years service plans in space five years service .

Work Principle
Spitzer Space Telescope's work in the wavelength range of 3 - 180 micron wavelength band of infrared rays, which replaced the former of the Infrared Astronomical Satellite (IRAS) Spitzer Space Telescope's work in the wavelength range of 3 - 180 micron wavelength band of infrared rays, which replaced the former of the Infrared Astronomical Satellite (IRAS) . Spitzer space telescope although not much larger than its diameter, yet with the rapid development of infrared detection device, the performance is improved remarkably Spitzer space telescope although not much larger than its diameter, yet with the rapid development of infrared detection device, the performance is improved remarkably .
Spitzer's infrared detection sensitivity is very high, at a wavelength of from 3 micrometers to 180 micrometers between all of the infrared radiation is able to collect all the "eye" Spitzer's infrared detection sensitivity is very high, at a wavelength of from 3 micrometers to 180 micrometers between all of the infrared radiation is able to collect all the "eye" . bottom while this band due to its range of radiation to reach the ground and that is guaranteed to be blocked by the Earth's atmosphere, ground - based telescopes to spot " bottom while this band due to its range of radiation to reach the ground and that is guaranteed to be blocked by the Earth's atmosphere, ground - based telescopes to spot ".
therefore Spitzer can detect in the universe makes it difficult to perceive objects, such as some of the small dim stars therefore Spitzer can detect in the universe makes it difficult to perceive objects, such as some of the small dim stars . with Optical astronomical observation, in contrast to Spitzer's infrared "eye" is able to penetrate dust and gas, saw its infinite mystery behind with Optical astronomical observation, in contrast to Spitzer's infrared "eye" is able to penetrate dust and gas, saw its infinite mystery behind .
on 25 August 2003, the Spitzer space telescope in Winter Park, Florida, the Cape Canaveral Air Force Station by a Delta II rocket was launched, operating in one of the earth's rear, orbit around the Sun, with an annual 0.1 astronomical unit of speed is gradually away from the Earth, which makes the event of a fault, will not be able to use the shuttle to repair it 
Specification Of Equipment

160 in order to avoid the telescope itself, the infrared rays emitted from the interference, the primary mirror cooled to a temperature 5. 5K telescope itself is also provided with a protective cover, in order to avoid the sun and the earth emitted infrared interference telescope itself is also provided with a protective cover, in order to avoid the sun and the earth emitted infrared interference .
in the disc, is a great deal of dust and gas that blocks visible light,Thus the earth directly with optical telescopes on the galaxy near the center of the region of the in the disc, is a great deal of dust and gas that blocks visible light,Thus the earth directly with optical telescopes on the galaxy near the center of the region of the . infrared wavelength longer than that of visible light, can penetrate dense dust, so the infrared observation can help people understand the core of the Milky Way, star formation and extrasolar planets infrared wavelength longer than that of visible light, can penetrate dense dust, so the infrared observation can help people understand the core of the Milky Way, star formation and extrasolar planets .
