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.

起源太空望远镜的低温冷却技术

Origins太空望远镜（Origins）对先前红外任务的科学能力的重大改进是基于其冷望远镜（4.5 K），低噪声远红外探测器和超稳定的中红外探测器。少量的新技术将使Origins能够接近自然天空背景强加的基本灵敏度极限，并提供开创性的科学。本文介绍了一项强大的计划，以使Origins任务成熟，从而使冷冻冷却器技术从当前的最新技术（SOA）到2025年达到技术就绪水平（TRL）5，并由任务初步设计评审提高到TRL 6。与当前SOA对应的Entry TRL为4或5，具体取决于所讨论的技术。
