论文摘要
洛普（Loupe）是地球未解决的极化法的月球天文台，是一个较小的，坚固的光谱仪，其任务是将地球视为系外行星。在恒星可居住的区域中检测类似地球的行星是现代系外行星科学的主要挑战之一。表征这种行星和寻找生命痕迹需要直接检测其信号。 Loupe提供了独特的光谱通量和地球反射的阳光的极化数据，地球是唯一已知的藏有生命的行星。该数据将用于测试数值代码，以预测类似地球的系外行星的信号，测试检索行星特性的算法，并微调未来空间观测值的设计和观察策略。在月球上，洛普（Loupe）将不断看到整个地球，使其能够监视由于行星每日旋转，天气模式和季节在全相角上引起的信号变化。在这里，我们同时介绍了Loupe的工具和任务设计背后的科学案例和技术。
LOUPE, the Lunar Observatory for Unresolved Polarimetry of the Earth, is a small, robust spectro-polarimeter with a mission to observe the Earth as an exoplanet. Detecting Earth-like planets in stellar habitable zones is one of the key challenges of modern exoplanetary science. Characterising such planets and searching for traces of life requires the direct detection of their signals. LOUPE provides unique spectral flux and polarisation data of sunlight reflected by the Earth, the only planet known to harbor life. This data will be used to test numerical codes to predict signals of Earth-like exoplanets, to test algorithms that retrieve planet properties, and to fine-tune the design and observational strategies of future space observatories. From the Moon, LOUPE will continuously see the entire Earth, enabling it to monitor the signal changes due to the planet's daily rotation, weather patterns, and seasons, across all phase angles. Here, we present both the science case and the technology behind LOUPE's instrumental and mission design.
