21世纪中期的空间天文学：机器人维护的Space Telescopes
Space Astronomy for the mid-21st Century: Robotically Maintained Space Telescopes
摘要：
地面天文望远镜的历史发展使我们预计天基天文望远镜将需要运行数十年。在空间交换科学仪器将是这类飞行任务长期取得科学成功的先决条件。在操作上，必须有可能在空间修理或更换航天器的关键部件。我们认为，这些要求可以通过机器人任务来实现，并将所需工程的发展视为主要挑战。地面行动在科学和技术上将需要较低的运行费用预算。这些可以通过增强航天器的自主性和独立于任务的软件支持概念来实现。这一概念可适用于镜像能力不限制飞行任务寿命的领域。
英文摘要：
The historical development of ground based astronomical telescopes leads us to expect that space-based astronomical telescopes will need to be operational for many decades. The exchange of scientific instruments in space will be a prerequisite for the long lasting scientific success of such missions. Operationally, the possibility to repair or replace key spacecraft components in space will be mandatory. We argue that these requirements can be fulfilled with robotic missions and see the development of the required engineering as the main challenge. Ground based operations, scientifically and technically, will require a low operational budget of the running costs. These can be achieved through enhanced autonomy of the spacecraft and mission independent concepts for the support of the software. This concept can be applied to areas where the mirror capabilities do not constrain the lifetime of the mission.
