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.
美国宇航局周二表示，波音公司（纽约证券交易所代码：BA）Starliner航天器飞往国际空间站的首次载人飞行测试现在将在不早于5月17日发射，此前计划于周一进行的发射暂停。
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.
发生了什么：在发现本应将航天器送入轨道的阿特拉斯五号火箭存在问题后，原定于周一进行的发射暂停。
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.
美国宇航局说，运营火箭的公司联合发射联盟已决定更换半人马座火箭末级液氧的压力调节阀，同时补充说，现在计划不早于美国东部时间5月17日星期五下午6点16分发射。
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.
更换将于5月8日星期三开始，ULA还将在下次发布之前进行泄漏检查和功能检查。该机构说，计划进行飞行的两名宇航员苏尼·威廉姆斯和巴里· “布奇” · 威尔摩将在美国宇航局肯尼迪机组人员宿舍隔离。
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.
为何重要：波音的Starliner航天器自一开始就面临过几次延误。该航天器本应在2015年进行首次无人驾驶试飞，但后来推迟到2019年。2022年，该航天器完成了首次前往国际空间站的无人飞行。
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.
如果即将到来的载人飞行测试成功，波音将成为下一家为美国宇航局穿梭宇航员往返国际空间站的私营公司，就像埃隆·马斯克的SpaceX一样。
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.
美国宇航局授予波音和SpaceX合同，允许在航天飞机退役后往返国际空间站。SpaceX于2020年通过其Dragon航天器向国际空间站执行了首次载人任务，此后又执行了多项任务，超越了其传统竞争对手。
