Space telescopes require cryogenic cooling to eliminate thermal infrared emission
Space-borne infrared telescopes incorporate cryogenic systems and components to manage thermal conditions and optimize infrared imaging performance.
The retrieved literature supports the necessity of cryogenic technologies and cooling for infrared space telescopes (such as in papers 4 and 8) to ensure high-sensitivity measurements and proper wavefront performance in the infrared spectrum.
