摘要：

The Spitzer Space Telescope (formerly called SIRTF) was launched into an Earth-trailing, solar orbit on August 25, 2003. The Cryogenic Telescope Assembly is Spitzer's instrument payload. The design operational lifetime is 5 years, limited by the loss rate from the superfluid helium cryostat that cools the instruments to 1.3 K and the telescope to 5.5 K by vapor cooling. The thermal/cryogenic system flight performance to date is meeting expectations.
