The Boeing Starliner (or CST-100) [c] is a spacecraft designed to transport crew to and from the International Space Station (ISS) and other low-Earth-orbit destinations. Developed by Boeing under NASA's Commercial Crew Program (CCP), it consists of a reusable crew capsule and an expendable service module.

波音CST-100星际客机 [5] （英語： Boeing CST-100 Starliner ，台湾作波音CST-100星際飛機 [6] ），或译为星际客船 [7] 、星际航线，是波音公司为美国国家航空航天局（NASA）的商業載人航天發展計畫研制的（载人）飞船。

Boeing's Crew Space Transportation (CST)-100 Starliner spacecraft is being developed in collaboration with NASA's Commercial Crew Program. The Starliner was designed to accommodate seven passengers, or a mix of crew and cargo, for missions to low-Earth orbit.

Feb 4, 2025 · Boeing announced Monday it lost $523 million on the Starliner crew capsule program last year, putting the aerospace company $2 billion in the red on its NASA commercial crew contract since late 2019.

2024年5月7日，美国国家航空航天局（NASA）宣布，为更换助推火箭上有故障的压力调节阀，波音“星际客机”（Starliner）飞船首次载人试飞的目标发射日期推迟，不会早于当地时间5月17日；5月19

Sep 7, 2024 · NASA astronauts Butch Wilmore and Suni Williams launched on June 5 aboard Starliner for the agency’s Boeing Crewed Flight Test from Cape Canaveral Space Force Station in Florida.

Dec 18, 2024 · The astronaut duo who flew the first-ever crewed mission of Boeing's Starliner capsule will have to wait a little longer to rejoin us on Earth.

“星际客机”飞船（英文：Starliner，又译：星际线），是美国波音公司研制的新一代可重复使用的锥形载人飞船，担负运送美国宇航员往返国际空间站任务。

2015年9月4日，美国波音公司正式将CST-100载人飞船命名为“Starliner”。 2022年5月19日，波音“星际客机”（CST-100 Starliner）第二次不载人轨道试飞任务将前往国际空间站，搭乘美国联合发射联盟公司“宇宙神5”火箭从佛罗里达州卡纳维拉尔角太空部队基地发射升空。

初期Starliner将由ULA的宇宙神5（N22）发射，后期或考虑由ULA新火箭火神火箭发射。据波音给出的数据，每一个Starliner将复用十次。 相较于SpaceX的载人龙，波音的Starliner货运能力更差，单座票价更高，研发费用更高，且尚未投入使用。 结构
