NASA is preparing the SLS (Space Launch System) rocket core stage that will help power the first crewed mission of NASA’s Artemis campaign for shipment. On July 6, NASA and Boeing, the core stage lead contractor, moved the Artemis II rocket stage to another part of the agency’s Michoud Assembly Facility in New Orleans. The move comes as teams prepare to roll the massive rocket stage to the agency’s Pegasus barge for delivery to NASA’s Kennedy Space Center in Florida in mid-July.

Prior to the move, technicians began removing external access stands, or scaffolding, surrounding the rocket stage in early June. NASA and Boeing teams used the scaffolding surrounding the core stage to assess the interior elements, including its complex avionics and propulsion systems. The 212-foot core stage has two huge propellant tanks, avionics and flight computer systems, and four RS-25 engines, which together enable the stage to operate during launch and flight.

The stage is fully manufactured and assembled at Michoud. Building, assembling, and transporting is a joint process for NASA, Boeing, and lead RS-25 engines contractor Aerojet Rocketdyne, an L3Harris Technologies company.

NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

NASA正在为其太空发射系统（SLS）火箭的核心级做准备，以支持NASA阿尔忒弥斯计划的首次载人任务。7月6日，NASA和核心级主承包商波音公司将阿尔忒弥斯II号火箭级移动到该机构位于新奥尔良的米丘德装配厂的另一部分。此举是为了准备在7月中旬将这台庞大的火箭级运送到NASA位于佛罗里达的肯尼迪航天中心。

在移动之前，技术人员在6月初开始拆除围绕火箭级的外部通道支架或脚手架。NASA和波音团队使用围绕核心级的脚手架来评估内部元素，包括其复杂的航空电子设备和推进系统。这个212英尺高的核心级有两个巨大的推进剂罐、航空电子设备和飞行计算机系统，以及四个RS-25发动机，这些组件共同使火箭级能够在发射和飞行期间运作。

这个核心级完全是在米丘德制造和组装的。建造、组装和运输是NASA、波音公司以及RS-25发动机主承包商Aerojet Rocketdyne（L3Harris Technologies公司）共同完成的过程。

NASA正在通过阿尔忒弥斯计划，致力于将第一位女性、第一位有色人种以及其首位国际合作伙伴宇航员送上月球。SLS是NASA深空探索骨干的一部分，其他部分包括猎户座飞船、地面支持系统、先进的宇航服和探测车、绕月轨道的门户以及商业载人登月系统。SLS是唯一能够在一次发射中将猎户座飞船、宇航员和补给送上月球的火箭。
