媒体简报：贝比科隆博水星探测计划（BepiColombo）迈向水星的下一个里程碑

欢迎回看欧洲空间局（European Space Agency, ESA）于2026年8月31日举行的在线新闻简报，了解ESA与日本航天局（JAXA）联合开展的贝比科隆博水星探测计划（BepiColombo）的最新进展，这是欧洲和日本首次对水星（Mercury）进行的探测任务。

Rewatch the European Space Agency's 31 August 2026 online press briefing on the latest developments of the ESA/JAXA BepiColombo mission, Europe's and Japan's first mission to Mercury.

本次简报重点介绍了定于2026年9月3日进行的水星转移模块（Mercury Transfer Module, MTM）分离的复杂性，这是标志着贝比科隆博水星探测计划进入水星抵达阶段的关键里程碑。简报还概述了未来面临的运行挑战和里程碑，包括2026年11月的水星轨道捕获，以及2026年12月两颗科学轨道器（ESA的MPO和JAXA的Mio）的分离。

This briefing focused on the complexities of the separation of the Mercury Transfer Module (MTM), scheduled for 3 September 2026, a critical milestone marking the start of BepiColombo’s Mercury arrival phase. It also provided an overview of the operational challenges and milestones ahead, including Mercury orbit insertion in November 2026 and the separation of the two science orbiters (ESA's MPO and JAXA's Mio) in December 2026.

简报还提供了任务状态的最新信息，并探讨了贝比科隆博水星探测计划在准备开始环绕水星运行之际所面临的科学机遇。在三位发言人进行陈述后，记者们有机会进行提问。

The briefing also provided an update on the mission’s status and explored the scientific opportunities that await as BepiColombo prepares to begin operations around Mercury. Journalists had the opportunity to ask questions following the presentations from three speakers:

贝比科隆博水星探测计划将成为有史以来送往水星的最复杂任务。其轨道器将成为仅有的第二和第三个环绕该行星（planet）运行的探测器。这颗小型荒漠世界靠近太阳，且比冥王星（Pluto）更难抵达，是内太阳系（inner solar system）中探测程度最低的行星。深入了解水星将有助于揭示整个太阳系（solar system）的历史。

BepiColombo will be the most complex mission ever sent to Mercury. Its orbiters will be only the second and third to orbit the planet. Close to the Sun and more difficult for an orbiter to reach than Pluto, this small desert world is the least explored planet of the inner Solar System. Learning more about Mercury will shed light on the history of the entire Solar System.

该任务是ESA与JAXA的合作项目，后者提供了水星磁层轨道器（Mercury Magnetospheric Orbiter, Mio）。

The mission is a collaboration between ESA and JAXA, the latter providing the Mercury Magnetospheric Orbiter (Mio).
