In-space infrastructures and the Modular Assembled Space Telescope (MAST)

摘要

Although current budget realities discourage optimism regarding future development of large spaceborne astronomical telescopes, it is prudent to identify options that may enhance future cost-benefit ratios and enhance system opportunities sooner rather than later. Using a concept for a 20 meter UV-Optical-IR (UVOIR) telescope known as the Modular Assembled Space Telescope (MAST) assembled in space and operating in Sun-Earth L2 (SEL2) halo orbit as a baseline, this paper discusses proposed concepts and technologies for infrastructures related to deep space human and robotic exploration missions that could create opportunities for such a space telescope. The paper also explores the possibility that a telescope such as MAST or the related infrastructure could itself be leveraged to benefit other missions, for example through shared use of space and ground infrastructure, in-space operational experience, or other forms of collaboration.
