星舰完成第六次试飞：助推器改落墨西哥湾、飞船首次在太空重启发动机
美国德克萨斯州卡梅伦县的 Starbase 发射场11月19日迎来 SpaceX 星舰（Starship）的第六次试飞。发射窗开启之时，超重型（Super Heavy）助推器的33台猛禽（Raptor）发动机全部点火，星舰自发射台升空。
上升与级间分离一切正常后，助推器点火开始返回发射场。就在这一阶段，发射与回收塔关键硬件的自动健康检查触发了中止条件，原定的发射塔捕获尝试被取消。助推器随即执行预先设定的改道机动，完成着陆点火，在墨西哥湾软溅落。
星舰飞船本体则沿预定亚轨道轨迹继续飞行，并在太空中成功重启一台猛禽发动机——这一步验证的是飞船在全面轨道任务开始前执行离轨点火所需的能力。在 Starlink 实时回传画面与遥测数据的支持下，飞船穿过再入阶段，完成翻转与着陆点火，升空约65分钟后在印度洋软溅落。
SpaceX 表示，本次多项热防护实验的数据，以及以更激进攻角进行亚音速飞行取得的数据，将直接用于提高这套全可复用系统的可靠性，公司正朝着飞船本体也能返回并被捕获的目标推进。（来源：SpaceX）
SpaceX Starship Completes Sixth Flight Test: Booster Diverts to Gulf, Ship Relights Raptor in Space
SpaceX launched the sixth flight test of its Starship vehicle on November 19 from Starbase in Cameron County, Texas, at the start of the launch window, with all 33 Raptor engines on the Super Heavy booster powering the vehicle off the pad.
After a nominal ascent and stage separation, the booster began its boostback burn to return to the launch site. During that phase, automated health checks of critical hardware on the launch and catch tower triggered an abort of the planned catch attempt. The booster then executed its pre-planned divert maneuver, performed a landing burn and made a soft splashdown in the Gulf of Mexico.
The Starship upper stage completed its ascent onto the expected suborbital trajectory and successfully reignited a single Raptor engine while in space, demonstrating the capability required to conduct a ship deorbit burn before fully orbital missions begin. With live views and telemetry relayed by Starlink, the ship made it through reentry, executed a flip and a landing burn, and splashed down softly in the Indian Ocean about 65 minutes after liftoff.
SpaceX said data from multiple thermal protection experiments, and from flying at subsonic speeds at a more aggressive angle of attack, would feed directly into making the fully reusable system more reliable, as the company works toward eventual return and catch of the ship itself. (Source: SpaceX)
