TUBIN is a microsatellite mission tasked with the demonstration of microbolometer technology for the detection of high-temperature events. To this end, the spacecraft employs a set of two microbolometers sensitive in the thermal range of the electromagnetic spectrum as well as a complementary CMOS-based imager for the visible spectrum. Additionally, the mission serves to demonstrate the upgraded capabilities of the TUBiX20 microsatellite platform after its initial implementation within the TechnoSat mission, launched in 2017. Therefore, the platform was upgraded with star trackers for enhanced attitude determination to enable the pointing accuracy required by the mission. Launched in June 2021, TUBIN has already successfully detected wildfires and volcanic activity in different biomes across the globe. Additionally, the sensor suite of the TUBIN mission was applied to examine its capabilities in the assessment of light-pollution in dedicated night time imaging campaigns. In this paper, we present and analyze data sets captured in the first six months of operation to illustrate capabilities, accomplishments, and challenges regarding payload operation, calibration, and data analysis for the TUBIN mission. Finally, the plans for the second half of TUBIN’s nominal lifetime are outlined, including an on-orbit calibration campaign and increased automation in payload operations.

TUBIN 是一项微型卫星任务，其任务是演示用于检测高温事件的微测辐射热计技术。为此，航天器采用了一组两个对电磁光谱的热范围敏感的微测辐射热计，以及一个基于互补 CMOS 的可见光谱成像仪。此外，该任务用于展示 TUBiX20 微卫星平台在 2017 年发射的 TechnoSat 任务中首次实施后的升级功能。因此，该平台升级了星跟踪器以增强姿态确定，以实现任务所需的指向精度. TUBIN 于 2021 年 6 月推出，已成功检测到全球不同生物群落中的野火和火山活动。此外，TUBIN 任务的传感器套件用于检查其在专门的夜间成像活动中评估光污染的能力。在本文中，我们展示并分析了在运行的前六个月捕获的数据集，以说明 TUBIN 任务的有效载荷运行、校准和数据分析方面的能力、成就和挑战。最后，概述了 TUBIN 标称寿命后半段的计划，包括在轨校准活动和提高有效载荷操作的自动化程度。TUBIN 任务的有效载荷操作、校准和数据分析方面的挑战。最后，概述了 TUBIN 标称寿命后半段的计划，包括在轨校准活动和提高有效载荷操作的自动化程度。TUBIN 任务的有效载荷操作、校准和数据分析方面的挑战。最后，概述了 TUBIN 标称寿命后半段的计划，包括在轨校准活动和提高有效载荷操作的自动化程度。
