SpaceX 星舰第十次试飞完成全部主要目标 首次成功释放模拟卫星
2025年8月26日傍晚，SpaceX 的星舰（Starship）在位于德克萨斯州卡梅伦县的星舰基地（Starbase）完成第十次综合试飞。SpaceX 表示，这次飞行达成了全部主要目标，包括星舰飞船首次在太空释放载荷。
中部时间18时30分，星舰自发射台升空，超重型助推器的33台猛禽（Raptor）发动机全部点火，随后完成热分离。助推器在返回阶段进行着陆燃烧，期间按计划故意关停一台中央发动机、改用备用发动机完成收尾，悬停后溅落于墨西哥湾（美国湾）。
飞船完成全程上升燃烧、进入亚轨道后，依次打开载荷舱门，释放8颗星链（Starlink）模拟卫星，这是星舰首次完成载荷部署演示。飞船还完成了第二次太空猛禽发动机重启。再入阶段，SpaceX 刻意对飞船的隔热与结构加压测试。最终，飞船在四个翼面控制下于印度洋完成着陆翻转、着陆燃烧与软溅落，全程约66分30秒。
这次试飞此前两度推迟：8月24日因地面系统泄漏取消，8月25日因天气再次顺延。星舰今年1月的第七次试飞与3月的第八次试飞接连失利，飞船均在上升阶段损失；这一次，载荷部署、太空重启与受控溅落等关键科目在一次飞行中全部走通。

SpaceX Starship Completes All Major Objectives on 10th Test Flight, Deploys Payload for the First Time
On the evening of August 26, 2025, SpaceX's Starship completed its 10th integrated flight test from Starbase in Cameron County, Texas, with the company saying the flight achieved all of its major objectives, including the first deployment of a payload in space.
Starship lifted off at 6:30 p.m. Central Time, with all 33 Raptor engines of the Super Heavy booster igniting, followed by hot staging. During its return, the booster performed a landing burn in which one center engine was deliberately shut down and a backup engine used to finish the burn, then hovered before splashing down in the Gulf of Mexico (Gulf of America).
After a full-duration ascent burn into a suborbital trajectory, the ship opened its payload door and released eight Starlink simulator satellites, Starship's first payload deployment demonstration. The ship also completed a second in-space Raptor relight. During reentry, SpaceX deliberately stressed the ship's heat shield and structure. Guided by its four flaps, the ship then performed a landing flip, a landing burn and a soft splashdown in the Indian Ocean, ending a flight of about 66 minutes and 30 seconds.
The flight had been postponed twice: a ground systems leak scrubbed the August 24 attempt, and weather delayed the August 25 attempt. Starship's seventh flight in January and eighth flight in March of this year both ended with the ship lost during ascent; on this 10th flight, payload deployment, the in-space relight and the controlled splashdown were all completed in a single mission.
