（NewsNation）——美国国家航空航天局（NASA）计划于年底执行波音公司备受争议的“星际客机”（Starliner）飞船的无人试飞任务，在载人试飞失败后继续推进该项目。
(NewsNation) — NASA is planning an uncrewed test flight of Boeing’s troubled Starliner capsule for the end of the year, pushing ahead with the project after a failed crewed test flight.
NASA局长贾里德·艾萨克曼（Jared Isaacman）周一宣布，在发生“A类事故”（该等级用于指代最严重的问题）后，NASA将向该项目提供额外的资金和支持。
NASA administrator Jared Isaacman announced Monday that NASA would be putting extra money and support behind the project after its “Type A mishap,” a designation used for the most severe problems.
改进版的“星际客机”飞船最早将于12月发射，执行一项前往国际空间站的无人货运任务。
An improved Starliner is set to launch no earlier than December, carrying cargo on an uncrewed mission to the International Space Station.
预计宇航员要到2028年才能乘坐该飞船飞行，因为安全重新设计可能需要数月甚至数年时间才能完成。宇航员伍迪·霍伯格（Woody Hoburg）将担任该任务的指令长，但NASA尚未公布其机组成员的信息。
Astronauts are not expected to fly on the capsule until 2028, with safety redesigns expected to take months or years to complete. Astronaut Woody Hoburg is set to command the mission, though NASA has not released information on his crewmates.
“星际客机”的首次载人任务以失败告终，宇航员巴奇·威尔莫尔（Butch Wilmore）和苏尼·威廉姆斯（Suni Williams）原本计划在国际空间站停留8至10天，结果被延长至9个月。
Starliner’s first crewed mission fell apart after astronauts Butch Wilmore and Suni Williams found their eight-to-10-day ISS stay extended to nine months.
在经历氦气泄漏和五个姿态控制推进器故障后，“星际客机”仍安全抵达国际空间站，并搭载了机组人员。
After experiencing issues with helium leaks and the failure of five reaction control system thrusters, Starliner made it safely to the ISS with its crew.
然而，NASA认定该飞船无法安全地将机组人员送回地球，最终将“星际客机”分离，让其无人返回地球，并制定了替代方案将威廉姆斯和威尔莫尔带回地球。
However, NASA deemed the capsule unsafe to ferry its crew back home, eventually jettisoning Starliner for an unpiloted trip back to Earth and developing an alternate plan to bring Williams and Wilmore back to Earth.
这两位宇航员最终乘坐SpaceX的“龙”飞船返回家园，而“星际客机”则被停飞，NASA和波音公司试图查明故障原因。
The two astronauts eventually made their way home on a SpaceX Dragon capsule, leaving Starliner grounded while NASA and Boeing attempted to determine what went wrong.
计划对“星际客机”进行的维修包括更换密封件以防止氦气泄漏，并开发一种工艺以防止导致部分推进器失效的姿态控制系统（RCS）推进器腐蚀。
Planned repairs to Starliner include replacing seals to prevent helium leaks and developing a process to prevent corrosion on the RCS thrusters that caused some of them to fail.
NASA的目标是拥有两种基于美国的宇航员往返国际空间站的方式，但“星际客机”的困境使得该机构不得不依赖SpaceX，而该公司计划到2030年逐步淘汰其服务。
NASA’s goal was to have two U.S.-based ways to transport astronauts to and from the ISS, but Starliner’s woes made the agency reliant on SpaceX, which the company is set to phase out by 2030.
国际空间站本身目前计划于2031年退役，不过美国私营企业正在研发轨道空间站，这些空间站需要为驻留人员提供可靠的运输服务。
The ISS itself is currently set to be abandoned by 2031, though private U.S. companies are working on orbital stations that would need reliable transport for occupants.
修复“星际客机”将耗资美国国家航空航天局3.59亿美元，但这将为该机构提供一个新的载人飞船选项，因为SpaceX正转向“星舰”——该飞船体积过大，无法对接传统空间站——并将重心转向以火星旅行为首要目标。
Fixing Starliner will cost NASA $359 million, but would give the agency a new crew vehicle option as SpaceX pivots to Starship, which is too large for traditional docking stations, and shifts focus to Mars travel as a primary goal.
