Abstract

The Stratospheric Observatory for Infrared Astronomy (SOFIA), a joint project between NASA and the German Aerospace Center DLR, provides access to observations of the infrared and sub-millimeter universe. As its development timeline is unique compared to all other NASA astrophysics missions, a milestone called the Full Operation Capability (FOC) was defined to identify the start of science operations. SOFIA reached this in February 2014. With a wide range of imagers, spectrometers and a new polarimeter, SOFIA provides unique scientific results that cannot be obtained with a ground-based facility and any spacecraft expected in the next decade. The airborne platform has continued to mature its mission systems as part of a planned spiral development approach, particularly with upgradable instrumentation that opens up new science directions for the Observatory. A third generation instrument is planned for commissioning in 2019. This paper summarizes the current state of the Observatory with emphasis on the science and instrumentation updates since FOC.

平流层红外天文观测站全面运行以来概况

平流层红外天文观测站(SOFIA)是美国宇航局和德国航空航天中心DLR之间的一个联合项目，提供了对红外和亚毫米宇宙的观测。由于其开发时间表与美国宇航局所有其他天体物理任务相比是独一无二的，因此定义了一个称为全面操作能力(FOC)的里程碑，以确定科学操作的开始。SOFIA于2014年2月达到这一目标。SOFIA拥有广泛的成像仪、光谱仪和一个新的偏振计，可以提供独特的科学结果，这是地面设施和未来十年任何航天器都无法获得的。作为计划的螺旋发展方法的一部分，机载平台继续使其任务系统成熟，特别是可升级的仪器，为天文台开辟了新的科学方向。第三代仪器计划于2019年调试。本文总结了自FOC以来天文台的现状，重点介绍了科学和仪器的更新。

期刊介绍： The Journal of Astronomical Instrumentation (JAI) publishes papers describing instruments and components being proposed, developed, under construction and in use. JAI also publishes papers that describe facility operations, lessons learned in design, construction, and operation, algorithms and their implementations, and techniques, including calibration, that are fundamental elements of instrumentation. The journal focuses on astronomical instrumentation topics in all wavebands (Radio to Gamma-Ray) and includes the disciplines of Heliophysics, Space Weather, Lunar and Planetary Science, Exoplanet Exploration, and Astroparticle Observation (cosmic rays, cosmic neutrinos, etc.). Concepts, designs, components, algorithms, integrated systems, operations, data archiving techniques and lessons learned applicable but not limited to the following platforms are pertinent to this journal. Example topics are listed below each platform, and it is recognized that many of these topics are relevant to multiple platforms. Relevant platforms include: Ground-based observatories[...] Stratospheric aircraft[...] Balloons and suborbital rockets[...] Space-based observatories and systems[...] Landers and rovers, and other planetary-based instrument concepts[...]
