Engineers at NASA’s Kennedy Space Center in Florida completed stacking the twin SLS (Space Launch System) solid rocket boosters – seen in this Feb. 19, 2025, photo – inside the Vehicle Assembly Building for the agency’s Artemis II crewed test flight around the Moon.
During stacking operations, which began Nov. 20, 2024, technicians used a massive overhead crane to lift each booster segment into place on mobile launcher 1, the 380-foot-tall structure used to process, assemble, and launch the SLS rocket and Orion spacecraft.

位于佛罗里达州的NASA肯尼迪航天中心的工程师已经完成了SLS（太空发射系统）双固体火箭助推器的堆叠工作，如2025年2月19日的照片所示。这些助推器被组装在航天器装配大楼（VAB）内，为NASA的阿尔忒弥斯二号（Artemis II）载人绕月测试飞行做准备。
此次堆叠工作始于2024年11月20日，技术人员利用巨型悬挂式起重机，将每个助推器的不同部分吊装到移动发射平台1（Mobile Launcher 1）上。这座高达380英尺（约116米）的结构用于SLS火箭和猎户座飞船的组装、处理和发射。
