Cryocooling Technologies For The Origins Space Telescope
JOURNAL OF ASTRONOMICAL TELESCOPES INSTRUMENTS AND SYSTEMS(2021)
Abstract
The Origins Space Telescope's (Origins) significant improvement over the scientific capabilities of prior infrared missions is based on its cold telescope (4.5 K) combined with low-noise far-IR detectors and ultrastable mid-IR detectors. A small number of new technologies will enable Origins to approach the fundamental sensitivity limit imposed by the natural sky background and deliver groundbreaking science. This paper describes a robust plan to mature the Origins mission, enabling cryocooler technology from current state-of-the-art (SOA) to Technology Readiness Level (TRL) 5 by 2025 and to TRL 6 by mission Preliminary Design Review. Entry TRLs corresponding to today's SOA are 4 or 5, depending on the technology in question. (C) The Authors. Published by SPIE under a Creative Commons Attribution 4.0 Unported License.
