面对SpaceX龙飞船计划在2030年或更早前退役的局面，NASA正在加强对波音Starliner的投入。1龙飞船目前是NASA进行常规低地球轨道宇航员任务的唯一可运营航天器，其退役将使美国面临运力空缺。1
为确保运输连续性，NASA计划下周宣布订购两个额外的Starliner载人任务，并将部分资助该航天器推进器问题的修复工作。1此外，NASA还将为Starliner在新火箭上的认证工作提供支持。1
NASA is moving to expand its reliance on Boeing's Starliner spacecraft as SpaceX's Dragon vehicle approaches retirement. SpaceX has indicated in recent discussions that it plans to retire the Dragon capsule in 2030 or earlier 1. With Dragon currently serving as NASA's only operational spacecraft for routine low Earth orbit astronaut missions 1, the agency is taking steps to ensure continuity in human spaceflight capabilities.
To bolster the Starliner program, NASA plans to announce the purchase of two additional crewed Starliner missions 1. The agency will also provide partial funding to address propulsion system issues affecting the spacecraft 1 and support its certification on a new rocket 1. These measures underscore NASA's commitment to developing a more diversified approach to crew transportation following Dragon's anticipated retirement.
