球载日美红外线干涉测量实验（JUSTIInE）是第一个天基远红外线干涉仪的探路者。JUSTIInE将使空间光谱远红外干涉测量的系统一级技术准备成熟，并通过科学观测演示这一技术。工作波长从30到90微米，JUSTIInE将提供前所未有的亚弧秒角分辨率和光谱数据。我们的计划是开发一种低温迈克尔逊光束组合器，并将其与日本远红外干涉望远镜实验（FITE）现有的和经过测试的望远镜光学系统和吊舱集成在一起。通过两次JUSTIInE气球飞行，我们计划根据对年轻恒星物体、演化恒星和NGC 1068活动星系核的首次远红外空间光谱观测来收集、校准、分析和发布科学结果。美国宇航局天体物理学路线图设想了一个从远红外开始在整个电磁频谱中应用干涉测量的未来。2021年十年调查中推荐的远红外探测器为迈出这一重要步骤提供了机会。基于这一概念的远红外探测器使命将使我们能够了解类地行星的形成，并通过光谱研究单个遥远星系，以了解支配它们演化的天体物理过程。
The balloon-borne Japan-United States Infrared Interferometry Experiment (JUStIInE) is a pathfinder for the first space-based far-IR interferometer. JUStIInE will mature the system-level technology readiness of spatio-spectral far-IR interferometry and demonstrate this technique with scientific observations. Operating at wavelengths from 30 to 90 µm, JUStIInE will provide unprecedented sub-arcsecond angular resolution and spectroscopic data. Our plan is to develop a cryogenic Michelson beam combiner and integrate it with an existing and tested telescope optical system and gondola from the Japanese Far-infrared Interferometric Telescope Experiment (FITE). With two JUStIInE balloon flights we plan to collect, calibrate, analyze, and publish scientific results based on the first far-IR spatio-spectral observations of young stellar objects, evolved stars, and the active galactic nucleus of NGC 1068. The NASA Astrophysics Roadmap envisages a future in which interferometry is applied across the electromagnetic spectrum, starting in the far-infrared. The Far-IR Probe recommended in the 2021 Decadal Survey presents an opportunity to take that important step. A Far-IR Probe mission based on this concept will enable us to understand terrestrial planet formation and spectroscopically study individual distant galaxies to understand the astrophysical processes that govern their evolution.
