「双语太空播报」NASA月球火箭骨干加入阿耳特弥斯一号任务助推器

The core stage of the Space Launch System (SLS) rocket for NASA’s Artemis I mission has been placed on the mobile launcher in between the twin solid rocket boosters inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center. The boosters attach at the engine and intertank sections of the core stage. Serving as the backbone of the rocket, the core stage supports the weight of the payload, upper stage, and crew vehicle, as well as carrying the thrust of its four engines and two five-segment solid rocket boosters. After the core stage arrived on April 27, engineers with Exploration Ground Systems and contractor Jacobs brought the core stage into the VAB for processing work and then lifted it into place with one of the five overhead cranes in the facility.

Once the core stage is stacked alongside the boosters, the launch vehicle stage adapter, which connects the core stage to the interim cryogenic propulsion stage (ICPS), will be stacked atop the core stage and quickly followed by the ICPS.

Artemis I will be an uncrewed test of the Orion spacecraft and SLS rocket as an integrated system ahead of crewed flights to the Moon. Under the Artemis program, NASA aims to land the first woman and first person of color on the Moon in 2024 and establish sustainable lunar exploration by the end of the decade.

NASA阿耳特弥斯一号任务的空间发射系统（SLS）火箭的核心级已放置在NASA肯尼迪航天中心车辆装配大楼（VAB）内两个固体火箭助推器之间的移动发射器上。助推器安装在核心级的发动机和缸间部分。作为火箭的支柱，核心级支撑着有效载荷、上层和乘员车辆的重量，并承载着四个发动机和两个五段式固体火箭助推器的推力。4月27日，核心阶段到达后，勘探地面系统工程师和承包商Jacobs将核心阶段带入VAB进行处理工作，然后使用设施中五台桥式起重机中的一台将其提升到位。

一旦堆芯级与助推器堆叠在一起，将堆芯级与临时低温推进级（ICPS）连接的运载火箭级适配器将堆叠在堆芯级顶部，然后快速安装ICPS。

阿耳特弥斯一号将在载人登月飞行之前，对猎户座航天器和SLS火箭作为一个集成系统进行未覆盖测试。根据阿耳特弥斯计划，NASA的目标是在2024年将第一位女性和第一位有色人种登上月球，并在本世纪末建立可持续的月球探索。
