经过八年的飞行，欧洲空间局（ESA）与日本航天局（JAXA）合作的贝比科隆博水星探测计划（BepiColombo）即将进入水星抵达阶段。2026年9月3日，ESA的水星转移模块（MTM）将与BepiColombo的两颗空间科学（space science）轨道器分离——这是ESA尝试过的最具操作挑战性的行星（planet）抵达序列中的第一个重大步骤。
After eight years, the ESA/JAXA BepiColombo mission is about to enter its Mercury Arrival Phase. On 3 September 2026, ESA’s Mercury Transfer Module (MTM) will separate from BepiColombo’s two science orbiters – the first major step in one of the most operationally challenging planetary arrival sequences ever attempted by ESA.
欧洲空间局（European Space Agency, ESA）将于欧洲中部夏令时间（CEST）13:45对这一关键里程碑进行直播。敬请收看，从ESA任务控制中心现场见证该任务最复杂阶段的第一步。
The European Space Agency (ESA) will livestream the critical milestone from 13:45 CEST. Tune in and witness the first step of one of the most complex phases of the mission, live from ESA mission control.

ESA/JAXA BepiColombo任务已准备好迈向抵达其最终目的地——神秘行星水星（Mercury）的第一个关键步骤。在作为组合航天器共同飞行八年后，为BepiColombo的行星际旅程提供动力的ESA水星转移模块（MTM）将于2026年9月3日与BepiColombo的两颗空间科学轨道器分离。
The ESA/JAXA BepiColombo mission is ready for the first critical step towards arriving at its final destination, the mysterious planet Mercury. After eight years of travelling together as one stacked spacecraft, ESA’s Mercury Transfer Module (MTM), which has powered BepiColombo’s interplanetary journey, will separate from BepiColombo’s two science orbiters on 3 September 2026.
但分离仅仅是个开始。
But separation is only the beginning.
抵达水星非常困难。到达那里则更加困难。BepiColombo的抵达是ESA执行过的要求最高的操作序列之一。MTM在9月3日的分离只是第一步。在MTM分离后，ESA的环水星轨道器（Mercury Planetary Orbiter, MPO）和JAXA的水星磁层轨道器（Mercury Magnetospheric Orbiter, Mio）将于2026年11月共同进入水星轨道，随后于2026年12月相互分离。科学运行将于2027年4月开始。
Getting to Mercury is hard. Arriving there is even harder. BepiColombo's arrival is one of the most demanding operational sequences ever carried out by ESA. MTM's separation on 3 September is just the first step. After MTM has separated, in November ESA's Mercury Planetary Orbiter (MPO) and JAXA's Mercury Magnetospheric Orbiter (Mio) will enter orbit around Mercury together, before separating from each other in December 2026. Science operations will begin in April 2027.
该节目将从位于德国达姆施塔特的ESA欧洲空间操作中心（ESOC）进行现场直播，并将展示标志性的主控制室（Main Control Room）的实时画面，届时任务控制团队将执行分离操作。我们的联合主持人将分享任务的特殊时刻。ESA和JAXA的专家将提供幕后见解和专家分析。
The programme will be broadcast live from ESA's European Space Operations Centre (ESOC) in Darmstadt, Germany, and will feature live views from the iconic Main Control Room as the Mission Control Team carries out the separation operations. Our co-hosts will share special mission moments. ESA and JAXA experts will provide behind-the-scenes insights and expert analysis.
接下来是等待。分离后，地球上的团队将监听BepiColombo分离后的信号捕获情况，并进行首次检查，以确认航天器状态良好且操作按计划进行。
Then comes the wait. Following separation, teams on Earth will listen for BepiColombo’s post separation acquisition of signal and carry out the first checks to confirm the spacecraft is healthy and that the operation has gone to plan.

关于BepiColombo
About BepiColombo
BepiColombo于2018年10月20日发射，是欧洲空间局（ESA）与日本航天局（Japan Aerospace Exploration Agency, JAXA）的联合任务，在ESA的领导下运行。这是欧洲和日本首次执行水星任务，也是首次执行双航天器水星任务，更是人类历史上第二个进入这颗岩石行星轨道的任务。
Launched on 20 October 2018, BepiColombo is a joint mission between the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA), operated under ESA leadership. It is both Europe and Japan's first mission to Mercury, the first two-spacecraft mission to Mercury, and only the second mission to ever enter orbit about the rocky world.
该任务包括两颗科学轨道器：ESA的环水星轨道器（MPO）和JAXA的水星磁层轨道器（Mio）。欧洲的水星转移模块（MTM）一直负责将这些轨道器运送到水星。
The mission comprises two scientific orbiters: ESA’s Mercury Planetary Orbiter (MPO) and JAXA’s Mercury Magnetospheric Orbiter (Mio). The European Mercury Transfer Module (MTM) has been carrying the orbiters to Mercury.
在2026年末抵达水星期间，航天器将在Mio的极轨道（polar orbit）上分离。随后，MPO将机动进入其围绕该行星的专用极轨道。两颗轨道器的科学运行将于2027年4月开始。
During arrival at Mercury in late 2026, the spacecraft will separate in Mio’s polar science orbit. MPO will then manoeuvre to itsdedicated polar orbit around the planet. Science operations for both orbiters will begin in April 2027.
