Boeing Starliner Delays Continue: Crewed Flight Test To Occur No Earlier Than May 17, Says NASA
The first crewed flight test of Boeing Co's (NYSE:BA) Starliner spacecraft to the International Space Station will now be launched no earlier than May 17, NASA said on Tuesday, after the launch planned for Monday was halted.
美國宇航局週二表示，波音公司（紐約證券交易所代碼：BA）Starliner航天器飛往國際空間站的首次載人飛行測試現在將在不早於5月17日發射，此前計劃於週一進行的發射暫停。
What Happened: The launch planned for Monday was halted after an issue was identified with the Atlas V rocket that was supposed to carry the spacecraft to orbit.
發生了什麼：在發現本應將航天器送入軌道的阿特拉斯五號火箭存在問題後，原定於週一進行的發射暫停。
United Launch Alliance, the company operating the rocket, has decided to replace a pressure regulation valve on the liquid oxygen taken on the rocket's Centaur upper stage, NASA said, while adding that the launch is now planned for no earlier than 6:16 p.m. EDT Friday, May 17.
美國宇航局說，運營火箭的公司聯合發射聯盟已決定更換半人馬座火箭末級液氧的壓力調節閥，同時補充說，現在計劃不早於美國東部時間5月17日星期五下午6點16分發射。
The replacement will begin on Wednesday, May 8, and ULA will also perform leak checks and functional checkouts ahead of the next launch. The two astronauts slated to undertake the flight, Suni Williams and Barry "Butch" Wilmore will remain in quarantine at NASA Kennedy crew quarters in the meantime, the agency said.
更換將於5月8日星期三開始，ULA還將在下次發佈之前進行泄漏檢查和功能檢查。該機構說，計劃進行飛行的兩名宇航員蘇尼·威廉姆斯和巴里· “布奇” · 威爾摩將在美國宇航局肯尼迪機組人員宿舍隔離。
Why It Matters: Boeing's Starliner spacecraft has been faced with several delays since the start. The spacecraft was supposed to have its first uncrewed test flight in 2015 which was delayed up to 2019. In 2022, the spacecraft completed its first uncrewed flight to the International Space Station.
爲何重要：波音的Starliner航天器自一開始就面臨過幾次延誤。該航天器本應在2015年進行首次無人駕駛試飛，但後來推遲到2019年。2022年，該航天器完成了首次前往國際空間站的無人飛行。
If the upcoming crewed flight test is successful, Boeing will become the next private company to shuttle astronauts to and from the ISS for NASA, like Elon Musk's SpaceX.
如果即將到來的載人飛行測試成功，波音將成爲下一家爲美國宇航局穿梭宇航員往返國際空間站的私營公司，就像埃隆·馬斯克的SpaceX一樣。
NASA awarded both Boeing and SpaceX contracts to enable to and from transportation to the ISS after retiring its space shuttle. SpaceX sent its first crewed mission to the ISS in 2020 on its Dragon spacecraft and has since then undertaken multiple missions, overtaking its traditional rival.
美國宇航局授予波音和SpaceX合同，允許在航天飛機退役後往返國際空間站。SpaceX於2020年通過其Dragon航天器向國際空間站執行了首次載人任務，此後又執行了多項任務，超越了其傳統競爭對手。
