降低大型空间望远镜成本的途径

天体物理仪器与方法 2023-10-23 v2

摘要

新的发展途径,包括运载火箭以及传感器、计算和软件的进步,降低了进入太空的成本门槛,并引发了低成本、高风险小卫星(SmallSat)任务的一场变革。为使更大的空间望远镜发生类似转变,有必要重新思考空间天文台的整体范式。在此,我们将回顾空间望远镜的发展历史与成本驱动因素,并描述一个低成本 6.5 m 光学望远镜的概念设计示例,以在室温下于太空运行时实现新科学。它采用硼硅玻璃整体式主镜,借鉴了地面天文台与仪器以及旗舰空间任务数十年的经验和工具。与大型运载火箭一样,它利用增强的计算能力和低成本主动预测控制系统中航天级商用电子器件来维持稳定性。我们将描述一种方法,该方法融合了科学和需求权衡研究结果,以应对在这种新风险容忍型“LargeSat”背景下如集成与测试成本、可靠性、航天器抖动和波前稳定性等主导性要求。
