Bepi-Colombo使命于2018年10月发射，前往水星。这一使命是欧洲和日本之间的合作。它致力于研究水星及其环境。经过7年的巡航，它将于2025年12月进入水星轨道。紫外光谱仪（PHEBUS）是一种紫外光谱仪，是水星行星轨道器（MPO）上的11种仪器之一。它致力于研究水星的外逸层、其组成、动力学和可变性及其与行星表面和太阳风的界面。PHEBUS仪器包含四个不同的检测器，覆盖55 nm至315 nm的光谱范围，以及404 nm和422 nm处的两个附加窄窗口。它也有一个单自由度的机制，允许观察沿着一个圆锥与一个半角度为80 ° 80 ^{\circ }$。本文遵循Chassefière等人提出的PHEBUS仪器设计的详细介绍。空间科学58：201-223，2010）。在这里，我们提出了一个更新的科学目标和测量要求后，由信使表面，空间环境，地球化学和测距（信使）使命公布的结果。我们还介绍了目前机载MPO的飞行单元的地面校准活动的结果。在最后一部分，我们介绍了一些细节的观测，将在水星巡航期间进行，如恒星观测活动，行星际背景观测和行星飞掠。
The Bepi-Colombo mission was launched in October 2018, headed for Mercury. This mission is a collaboration between Europe and Japan. It is dedicated to the study of Mercury and its environment. It will be inserted into Mercury orbit in December 2025 after a 7-year long cruise. Probing of Hermean Exosphere By Ultraviolet Spectroscopy (PHEBUS) is an ultraviolet Spectrograph and is one of the 11 instruments on-board the Mercury Planetary Orbiter (MPO). It is dedicated to the study of the exosphere of Mercury, its composition, dynamics and variability and its interface with the surface of the planet and the solar wind. The PHEBUS instrument contains four distinct detectors covering the spectral range from 55 nm up to 315 nm and two additional narrow windows at 404 nm and 422 nm. It also has a one-degree of freedom mechanism that allows observations along a cone with an half angle of 80 ∘ $80^{\circ }$ . This paper follows a detailed presentation of the PHEBUS instrument design that was presented by Chassefière et al. (Planet. Space Sci. 58:201–223, 2010 ). Here we present an update of the science objectives and measurement requirements following the results published by the MErcury Surface, Space ENvironment, GEochemistry and Ranging (MESSENGER) mission. We also present results of the ground calibration campaigns of the flight unit that is currently on-board MPO. In the last part, we present some details of the observations that will be performed during the cruise to Mercury, such as stellar observation campaigns, interplanetary background observations and planetary flybys.
