Table 1 summarizes for the readers the key properties of the Spitzer mission, and Fig. 1 shows a cutaway view of the observatory as flown. NASA launched Spitzer into an Earth-trailing solar orbit in August 2003 as a cryogenic telescope cooled by liquid helium and radiation to space. Description of the Spitzer Space Telescope These and other items of potential interest are addressed in references supplied in an appendix to this paper.ฤก.1. We avoid discussion of less unique systems, such as the telecom, flight software, and electronics systems, and do not address the innovations in mission and science operations that the Spitzer team initiated. We aim to facilitate the utility of the Spitzer engineering data by collecting the more unique and potentially useful portions into a single, readily accessible publication. In particular, the radiative cooling demonstrated by Spitzer has been adopted by other infrared space missions, from JWST to SPHEREx. These data will be particularly useful because Spitzer operated in an environment essentially identical to that at the L2 LaGrange point, where many future astrophysics missions will operate. ![]() The Spitzer Space Telescope operated for over 16 years in an Earth-trailing solar orbit, returning not only a wealth of scientific data but also, as a by-product, spacecraft and instrument engineering data that will be of interest to future mission planners. 6.5 Papers Describing In-Orbit Checkout.6.4 Papers Related to Science Operations.6.3 Papers Related to Mission Design and Mission Operations.6 Appendix A: Bibliography of Spitzer Resources with an Emphasis on Mission Science Operations.5.4 Be Alert to the Possibility of Repurposing Existing Flight Hardware.3.1 Optical System Verification and Focus Adjustment.2.6 Integration, Test, and Verification of the Cryothermal System.2.5 Maximizing the Cryogenic Lifetime of Spitzer.2.3 Solar Panel Shield and the Outer Shell.2.1 Thermal System Design and Performance: Use of Radiative Cooling. ![]() 1.1 Description of the Spitzer Space Telescope.
