AI总结:

本文概述了詹姆斯·韦布空间望远镜光学望远镜单元的需求、架构、研制与在轨性能,重点介绍其6.6 m拼接主镜及波前传感控制算法,并总结了经验教训与对未来更大空间望远镜的启示。

摘要:

詹姆斯·韦布空间望远镜(JWST)是一台大型红外空间望远镜,近期已启动其科学计划,将在天体物理学和行星科学领域带来突破性进展。值得注意的是,JWST 将首次观测宇宙中最早的发光天体,并开启系外行星大气表征的新时代。这一变革性科学能力由一台 6.6 m 望远镜实现,该望远镜通过 5 层遮阳罩进行被动冷却。主镜由 18 块可控、低面密度六边形子镜组成,这些子镜在轨利用基于图像的创新波前传感与控制算法完成了相互对准和共相。这台革命性望远镜历时二十余年研制,由跨工程学科的广泛分布团队完成。我们概述了该望远镜的需求、架构、研制过程、卓越的在轨性能以及经验教训。JWST 成功验证了拼接孔径空间望远镜方案,并为建造更大的空间望远镜开辟了道路。

英文摘要:

The James Webb Space Telescope (JWST) is a large, infrared space telescope that has recently started its science program which will enable breakthroughs in astrophysics and planetary science. Notably, JWST will provide the very first observations of the earliest luminous objects in the Universe and start a new era of exoplanet atmospheric characterization. This transformative science is enabled by a 6.6 m telescope that is passively cooled with a 5-layer sunshield. The primary mirror is comprised of 18 controllable, low areal density hexagonal segments, that were aligned and phased relative to each other in orbit using innovative image-based wavefront sensing and control algorithms. This revolutionary telescope took more than two decades to develop with a widely distributed team across engineering disciplines. We present an overview of the telescope requirements, architecture, development, superb on-orbit performance, and lessons learned. JWST successfully demonstrates a segmented aperture space telescope and establishes a path to building even larger space telescopes.
