抽象的。起源太空望远镜（Origins）比以前的红外任务的科学能力有了重大改进，其基础是冷望远镜（4.5 K）与低噪声远红外探测器和超稳定中红外探测器相结合。少量的新技术将使Origins接近自然天空背景所施加的基本灵敏度极限，并提供开创性的科学。本文描述了一项完善起源使命的稳健计划，使低温冷却器技术到2025年从当前最先进的（SOA）达到技术准备水平（TRL）5，并通过使命初步设计审查达到TRL 6。与今天的SOA相对应的入门TRL是4或5，这取决于所讨论的技术。
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.
