SpaceX星舰启动第14次试飞 首次挑战地球轨道与卫星部署SpaceX Launches Starship Flight 14 in First Orbital and Satellite Test
SpaceX定于2026年9月28日从得克萨斯州星基地发射星舰火箭进行第14次试飞，75分钟的发射窗口于美东时间上午8:15（当地时间7:15）开启，已在9月26日获得美国联邦航空管理局（FAA）的许可证授权。在前13次亚轨道测试之后，本次为期约10小时的试飞首次尝试进入高度约275公里、时速约2.8万公里的地球轨道，计划绕地飞行6圈并部署26颗新一代Starlink V3卫星，最终受控溅落太平洋；超重型助推器则计划溅落墨西哥湾，本次不尝试陆地机械臂捕获。 作为全球体量与推力最大的火箭系统，星舰完全可重复使用的技术验证直接关系到SpaceX的多项核心战略。该火箭承担着支撑已拥有约1.1万颗在轨卫星的星链网络扩张任务，并将用于支持美国宇航局（NASA）明年的登月测试任务以及运送宇航员重返月球；此外，公司还计划依托星舰在2027年发射太空AI计算卫星。进入轨道并验证升级版隔热罩的耐热表现，成为星舰从试验原型迈向商业化与深空任务运营的关键考验。
SpaceX is scheduled to launch its Starship rocket from Starbase, Texas, on September 28, 2026, for its 14th test flight, with a 75-minute launch window opening at 8:15 a.m. ET (7:15 a.m. CT) under a launch and reentry license authorized by the Federal Aviation Administration on September 26. Following 13 previous suborbital tests, this approximately 10-hour mission marks the company's first attempt to reach Earth orbit at an altitude of roughly 275 kilometers and a speed of about 28,000 km/h, aiming to complete six orbits, deploy 26 next-generation Starlink V3 satellites, and conclude with a controlled splashdown in the Pacific Ocean, while the Super Heavy booster is slated to splash down in the Gulf of Mexico without a mechanical arm catch. Demonstrating full reusability and heat shield performance on this orbital flight is critical to SpaceX's broader roadmap. The massive vehicle is designed to accelerate deployment for the Starlink satellite internet constellation, which currently operates around 11,000 satellites in orbit, while preparing for a vital NASA lunar test flight next year to return astronauts to the moon and supporting plans to launch in-orbit AI compute satellites by 2027.
01第14次试飞启动：瞄准首次轨道飞行与卫星部署Flight 14 Launch: Aiming for First Orbital Insertion and Satellite Deployment
根据SpaceX公布的发射安排，星基地发射场开放的75分钟窗口自美东时间上午8:15（当地时间7:15）启动，公司在社交媒体确认目标于窗口开启约半小时后实施点火。美国联邦航空管理局于9月26日正式向SpaceX签发了第14次试飞的发射与再入许可证，为这次长达10小时的复杂任务提供了监管许可。
According to SpaceX's mission schedule, the 75-minute launch window from its Starbase facilities opened at 8:15 a.m. ET (7:15 a.m. local time), with the company confirming on social media that it targeted liftoff approximately half an hour into the window. The Federal Aviation Administration granted the formal license authorization for the Starship Super Heavy Flight 14 launch and reentry operations on September 26, clearing regulatory requirements for the 10-hour test flight.
在飞行时序规划上，星舰升空后将先进入亚轨道飞行阶段，随后执行第二次发动机点火以尝试切入预定轨道。进入高度约275公里的轨道后，星舰将展开绕地6圈的巡航，并在此期间释放由华盛顿州雷德蒙德工厂生产的26颗新一代Starlink V3卫星。这批卫星配备了发电量提升一倍的太阳能电池阵列，旨在测试更高功率与更快数据传输能力的在轨部署流程。
Under the operational flight profile, Starship lifts off along an initial suborbital trajectory before conducting a critical second engine burn to enter a circular orbit around 275 kilometers above Earth. Once established in orbit, the spacecraft is scheduled to circle the planet six times while deploying 26 next-generation Starlink V3 satellites manufactured at SpaceX's facility in Redmond, Washington. These larger satellites feature solar arrays designed to generate twice as much power as earlier models, testing payload deployment mechanisms to deliver higher transmission speeds to the broadband network.
02入轨挑战与回收策略：海洋溅落及隔热罩升级验证Orbital Challenges and Recovery: Ocean Splashdowns and Heat Shield Upgrades
进入轨道飞行对推进与控制系统提出了更高要求。乔治敦大学安全与新兴技术中心高级分析师凯瑟琳·柯利向法新社指出，入轨过程需要更大的推力和更复杂的计算，火箭在承受不同重力水平时必须执行不同的动作，以达到每小时约2.8万公里的速度目标。
Reaching orbital velocity introduces heightened technical demands for propulsion and navigation. Kathleen Curlee, a senior analyst at Georgetown University's Center for Security and Emerging Technology, explained to AFP that achieving the target speed of roughly 28,000 kilometers per hour represents the most demanding operational phase, requiring greater forces, complex calculations, and specific rocket adjustments under fluctuating gravitational conditions.
在回收策略方面，超重型助推器将在发射后不久落入墨西哥湾海域，SpaceX本次并未安排陆地机械臂捕获。上级星舰在再入大气层时需经受超过2500华氏度的高温考验。基于今年7月第13次试飞后在印度洋打捞出的Ship 40残骸数据，SpaceX为本次执行任务的Ship 41升级了隔热罩，包括在易脱落区域增加紧固固定装置、采用能够减少瓦片缝隙受热的弧形瓦片设计，并首次将来自Ship 40的两块六边形旧隔热瓦安装于上级箭体进行复用测试。
For recovery operations, SpaceX does not plan to catch the giant Super Heavy booster with mechanical arms, directing it instead toward a controlled descent into the Gulf of Mexico. The upper Starship vehicle faces atmospheric reentry temperatures exceeding 2,500 degrees Fahrenheit. Utilizing hardware inspections from Ship 40—which was retrieved from the Indian Ocean following the July test flight—SpaceX implemented multiple upgrades on Ship 41's thermal protection system. These modifications include additional tile retention mechanisms in high-risk zones, a curved tile design engineered to limit heat penetration between tile gaps, and the flight test of two reused hexagonal tiles transferred directly from Ship 40.

03商业与深空战略：赋能星链扩张、月球探索及未来AI算力Commercial and Deep-Space Roadmaps: Starlink Scaling, Lunar Missions, and In-Orbit AI Compute
星舰的入轨验证与运力释放直接关系到SpaceX的核心商业化版图。作为公司二季度规模最大且唯一盈利的业务板块，星链目前在轨运行约1.1万颗活跃卫星，远超主要竞争对手欧洲通信卫星公司旗下OneWeb拥有的约650颗卫星。今年6月完成创纪录首次公开募股并达到约2万亿美元估值后，马斯克在8月的财报电话会上表示，星链未来有可能为全球绝大多数获准运营国家的受众提供大部分互联网接入服务。
Achieving orbital capability and delivering high payload capacity remain central to SpaceX's core commercial operations. Connectivity through Starlink stood as the company's largest and only profitable business segment as of the second quarter, maintaining around 11,000 active satellites in orbit compared to roughly 650 operated by rival Eutelsat OneWeb. Following its record initial public offering in June, which brought the company's valuation to approximately $2 trillion, Chief Executive Officer Elon Musk noted during an August earnings call that Starlink could eventually deliver a majority of internet services in countries where regulatory approval is granted.
在深空探索与前沿计算领域，星舰同样承担着核心任务。SpaceX正面临推进星舰研发的明确节点，以确保支持定于明年实施的NASA关键测试任务，推动美国宇航员重返月球表面，并逐步验证在轨加注燃料技术。此外，SpaceX首席运营官格温·肖特韦尔本月早些时候在All-In峰会上透露，公司计划利用星舰的高运载能力将超级算力送入太空，定于2027年开始发射轨道AI计算卫星，为更长远的火星与深空任务打下基础。
Beyond satellite broadband, Starship forms the backbone of SpaceX's deep-space and advanced computing ambitions. The company faces strict developmental milestones to prepare the launch vehicle for a vital NASA test flight next year aimed at returning American astronauts to the lunar surface, alongside future trials for in-orbit refueling. In addition, SpaceX Chief Operating Officer Gwynne Shotwell announced at the All-In Summit earlier this month that the company plans to deploy supercomputing infrastructure in space, scheduling launches of dedicated in-orbit AI compute satellites starting in 2027.
