NASA:阿尔特弥斯一号的发射仍将继续(取自NASA官网)

在佛罗里达州NASA肯尼迪航天中心的车辆装配大楼内,技术人员继续为Artemis I准备太空发射系统火箭和猎户座航天器。 

在修复氢气泄漏源的工作中,工程师在火箭发动机部分的内壁上发现了一个松动的配件,液氢脐带的快速断开装置就在那里连接。该组件称为“夹头”,是一个拳头大小的环,用于在装配操作期间引导快速断开。团队将通过与其他计划中的发射准备工作同时进入发动机部分来修复夹头。技术人员已经更换了尾部维修桅杆脐带式快速断开上的密封件,一旦解决了松动的夹头问题,他们将重新连接脐带板。 

美国宇航局继续瞄准八月下旬的发射期,并将在工程师检查了夹头后确定一个特定的目标发射日期。 

技术人员继续与电池激活相关的工作,并计划在本周末打开核心级电池,然后再将它们安装在火箭上。接下来,团队将开始飞行终止系统操作,其中包括移除核心级和助推器保险箱以及用于校准的臂设备,并移除并更换飞行单元的命令接收器解码器。安全和臂设备是一种手动机制,将飞行终止系统置于“安全”或“臂”配置中,而命令接收器解码器在系统被激活时接收并解码火箭上的命令。 

与此同时,在猎户座航天器上,团队安装了一个技术演示,将在深空测试数字辅助和视频协作。工程师们还在对乘员模块和欧洲服务模块加热器和传感器进行动力测试。 


原文如下:

Inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, technicians continue to prepare the Space Launch System rocket and Orion spacecraft for Artemis I.  

During work to repair the source of a hydrogen leak, engineers identified a loose fitting on the inside wall of the rocket’s engine section, where the quick disconnect for the liquid hydrogen umbilical attaches. The component, called a “collet,” is a fist-sized ring that guides the quick disconnect during assembly operations. Teams will repair the collet by entering the engine section in parallel with other planned work for launch preparations. Technicians have replaced the seals on the quick disconnect of the tail service mast umbilical and will reattach the umbilical plate once the loose collet is addressed.  

NASA continues to target the late August launch period and will identify a specific target launch date after engineers have examined the collet. 

Technicians continue work associated with battery activations, and plan to turn on the core stage batteries this weekend, before they are installed on the rocket. Next up, teams will start the flight termination systems operations, which include removing the core stage and booster safe and arm devices for calibration and removing and replacing the command receiver decoders with the flight units. The safe and arm devices are a manual mechanism that put the flight termination system in either a “safe” or “arm” configuration while the command receiver decoders receive and decode the command on the rocket if the system is activated. 

Meanwhile on the Orion spacecraft, teams installed a technology demonstration that will test digital assistance and video collaboration in deep space. Engineers are also conducting powered testing on the crew module and European service module heaters and sensors.
