空间红外线干涉测量望远镜旨在实现三个科学目标：（1）了解行星系统是如何从原恒星盘形成的，以及它们是如何获得其不均匀的化学成分的;（2）通过对碎片盘中的结构进行成像来确定太阳系外行星系统家族的特征，以了解不同类型行星的形成方式和形成地点;以及（3）了解高红移星系是如何形成和合并形成今天的星系群的。SPIRIT将通过使用双孔径干涉仪进行红外观测来实现这些目标。本文概述了SPIRIT的设计和运行，以及如何完成三个设计周期的概念研究。几个关键性能值的误差预算为所有影响因素分配了公差，航天器加仪器系统的性能模型表明，这些分配有余量。
The Space Infrared Interferometric Telescope (SPIRIT) was designed to accomplish three scientific objectives: (1) learn how planetary systems form from protostellar disks and how they acquire their inhomogeneous chemical composition; (2) characterize the family of extrasolar planetary systems by imaging the structure in debris disks to understand how and where planets of different types form; and (3) learn how high-redshift galaxies formed and merged to form the present-day population of galaxies. SPIRIT will accomplish these objectives through infrared observations with a two aperture interferometric instrument. This paper gives an overview of SPIRIT design and operation, and how the three design cycle concept study was completed. The error budget for several key performance values allocates tolerances to all contributing factors, and a performance model of the spacecraft plus instrument system demonstrates meeting those allocations with margin.
