在佛羅里達州NASA肯尼迪航天中心的車輛裝配大樓內(nèi)，技術(shù)人員繼續(xù)為Artemis I準備太空發(fā)射系統(tǒng)火箭和獵戶座航天器。?

在修復氫氣泄漏源的工作中，工程師在火箭發(fā)動機部分的內(nèi)壁上發(fā)現(xiàn)了一個松動的配件，液氫臍帶的快速斷開裝置就在那里連接。該組件稱為“夾頭”，是一個拳頭大小的環(huán)，用于在裝配操作期間引導快速斷開。團隊將通過與其他計劃中的發(fā)射準備工作同時進入發(fā)動機部分來修復夾頭。技術(shù)人員已經(jīng)更換了尾部維修桅桿臍帶式快速斷開上的密封件，一旦解決了松動的夾頭問題，他們將重新連接臍帶板。?

美國宇航局繼續(xù)瞄準八月下旬的發(fā)射期，并將在工程師檢查了夾頭后確定一個特定的目標發(fā)射日期。?

技術(shù)人員繼續(xù)與電池激活相關(guān)的工作，并計劃在本周末打開核心級電池，然后再將它們安裝在火箭上。接下來，團隊將開始飛行終止系統(tǒng)操作，其中包括移除核心級和助推器保險箱以及用于校準的臂設備，并移除并更換飛行單元的命令接收器解碼器。安全和臂設備是一種手動機制，將飛行終止系統(tǒng)置于“安全”或“臂”配置中，而命令接收器解碼器在系統(tǒng)被激活時接收并解碼火箭上的命令。?

與此同時，在獵戶座航天器上，團隊安裝了一個技術(shù)演示，將在深空測試數(shù)字輔助和視頻協(xié)作。工程師們還在對乘員模塊和歐洲服務模塊加熱器和傳感器進行動力測試。?

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.??
