星舰第八次试飞：助推器第三次被发射塔捕获、飞船升空约九分半后失联
2025年3月6日，SpaceX的星舰在位于德克萨斯州卡梅伦县的星舰基地（Starbase）进行第八次试飞。SpaceX在飞行总结中说，星舰于当地时间下午5时30分升空，超重型助推器点燃全部33台猛禽发动机，第一级上升段按计划完成。
升空约两分半钟后，超重型助推器按计划关停除三台以外的全部猛禽发动机、进行热分离；星舰飞船点燃六台猛禽发动机，与助推器分离后继续上升。助推器随后重新点燃计划13台中的11台发动机、执行返回点火，飞向发射场；在着陆点火开始时又点燃计划13台中的12台，减速后由三台中央发动机操纵、对准发射与捕获塔的塔臂——这是超重型助推器第三次被发射塔成功捕获。
飞船方面则未能完成这次飞行。SpaceX说，飞船继续沿计划轨迹上升，但在上升段结束之前，飞船尾部发生一次高能事件，导致数台猛禽发动机失效，进而失去姿态控制、最终与地面失去通信联系；与飞船的最后一次联系是在升空约9分30秒后。
SpaceX表示，星舰全程在指定的发射走廊内飞行，以保障地面、水上与空中公众的安全；异常发生后，公司团队立即与美国联邦航空管理局、空中交通管制部门及其他安全官员协调，执行预先制定的应急方案。SpaceX同时公布碎片报告渠道：如发现疑似碎片，可联系当地有关部门，或拨打SpaceX碎片热线1-866-623-0234、发邮件至[email protected]。
这次飞行的结果与第七次试飞相似：助推器再次被发射塔捕获回收，飞船则在上升段失联损失。星舰是SpaceX正在研制的可重复使用重型运载系统，由超重型助推器与星舰飞船两级组成，发射塔捕获助推器是其快速重复使用方案的一环。

Starship's Eighth Flight Test: Booster Caught for a Third Time, Ship Lost About Nine and a Half Minutes After Liftoff
On March 6, 2025, SpaceX flew the eighth flight test of Starship from Starbase in Cameron County, Texas. In its flight summary, SpaceX said Starship lifted off at 5:30 p.m. Central Time, with the Super Heavy booster lighting all 33 Raptor engines and completing a nominal first-stage ascent.
About two and a half minutes into the flight, the Super Heavy booster shut down all but three of its Raptor engines as planned for hot-staging separation, and the Starship ship lit its six Raptor engines and separated to continue its ascent. The booster then relit 11 of its 13 planned Raptor engines for a boostback burn toward the launch site; at the start of its landing burn it relit 12 of the planned 13 engines to slow down, with the three center engines maneuvering it to the launch and catch tower arms — the third successful catch of a Super Heavy booster.
The ship, however, did not complete the flight. SpaceX said Starship continued its ascent toward its planned trajectory, but before the end of the ascent burn an energetic event in the aft portion of the ship caused the loss of several Raptor engines, which led to a loss of attitude control and ultimately a loss of communications; final contact came approximately nine minutes and 30 seconds after liftoff.
SpaceX said Starship flew within a designated launch corridor to safeguard the public on the ground, on the water and in the air, and that after the anomaly its teams immediately began coordinating with the Federal Aviation Administration, air traffic control and other safety officials to implement pre-planned contingency responses. The company also published a debris-reporting channel: anyone who believes they have identified a piece of debris can contact local authorities or the SpaceX Debris Hotline at 1-866-623-0234 or [email protected].
The outcome mirrored the seventh flight test: the booster was caught by the launch tower again, while the ship was lost during ascent. Starship is SpaceX's reusable heavy-lift system, made up of the Super Heavy booster and the Starship upper stage, and catching the booster at the launch tower is part of its rapid-reuse approach.
