Watch SpaceX launch its 10,000th Starlink satellite to orbit today on rocket's record-breaking 31st flight

观看SpaceX今天将第10,000颗Starlink卫星送入轨道，这是火箭破纪录的第31次飞行

SpaceX will notch two big milestones on a single Falcon 9 launch today (Oct. 19), and you can watch the action live.

SpaceX将在今天（10月19日）的一次猎鹰9号发射中创下两个重大里程碑，你可以现场观看这一行动。

A Falcon 9 is scheduled to launch 28 of SpaceX's Starlink broadband satellites from Florida's Cape Canaveral Space Force Station today, during a four-hour window that opens at 10:52 a.m. EDT (1452 GMT).

猎鹰9号计划于今天从佛罗里达州卡纳维拉尔角太空部队站发射28颗SpaceX的Starlink宽带卫星，时间为美国东部时间上午10:52（格林威治标准时间1452）。

SpaceX has lofted 9,988 Starlink satellites to date, according to astrophysicist and satellite tracker Jonathan McDowell. So today's launch will take that number above 10,000. It will also be the record-breaking 31st liftoff for this Falcon 9's first stage, a booster designated 1067.

据天体物理学家和卫星追踪者乔纳森·麦克道尔称，迄今为止，SpaceX已经发射了9988颗Starlink卫星。因此，今天的发布将使这一数字超过10,000。这也将是猎鹰9号第一级破纪录的第31次升空，助推器编号为1067。

You can see history made live: SpaceX will stream the flight via its website and its X account, beginning about five minutes before launch.

你可以现场看到历史：SpaceX将通过其网站和X账户直播这次飞行，从发射前大约五分钟开始。

SpaceX launched its first two Starlink prototypes to low Earth orbit (LEO) in February 2018, then began building the megaconstellation in earnest 15 months later. The company offered Starlink service for the first time with a public beta test in October 2020 and started a commercial rollout the next year.

SpaceX于2018年2月向近地轨道(LEO)发射了前两个Starlink原型，然后在15个月后开始认真建造巨型星座。该公司于2020年10月首次提供Starlink服务，并于次年开始商业推广。

Starlink now provides service to millions of customers around the world, and SpaceX continues to beef up that product by sending more and more satellites to the final frontier.

Starlink现在为全球数百万客户提供服务，SpaceX继续通过向最终前沿发送越来越多的卫星来增强该产品。

The pace has reached extraordinary levels lately: SpaceX launched 89 Starlink missions in 2024 and has already exceeded that number this year. And don't expect it to stop anytime soon: SpaceX already has permission to loft 12,000 Starlink satellites, and the megaconstellation could eventually consist of more than 30,000 spacecraft.

最近这一速度达到了非凡的水平：SpaceX在2024年发射了89次Starlink任务，今年已经超过了这个数字。而且不要指望它会很快停止：SpaceX已经获得了放飞12,000颗Starlink卫星的许可，这个巨型星座最终可能由30,000多艘航天器组成。

Most of the 9,988 Starlink satellites that SpaceX has launched to date remain active — 8,610 are currently operational, according to McDowell. Most of the others have been deorbited, guided down to burn up in Earth's atmosphere. (Each Starlink satellite has an operational life of about five years.)

麦克道尔表示，SpaceX迄今为止发射的9,988颗Starlink卫星中的大多数仍然活跃——目前有8,610颗正在运行。其他的大部分已经脱离轨道，被引导到地球大气层中燃烧。（每颗星链卫星的运行寿命约为五年。）

If all goes according to plan today, Booster 1067 will come back to Earth about 8.5 minutes after liftoff, landing in the Atlantic Ocean on the SpaceX drone ship "A Shortfall of Gravitas." It will be the 31st launch and touchdown for the booster, according to a SpaceX mission description.

如果今天一切按计划进行，1067助推器将在升空后约8.5分钟返回地球，在SpaceX无人机飞船“A Shortfall Gravitas”上降落在大西洋。根据SpaceX的任务描述，这将是助推器的第31次发射和着陆。

Such extensive rocket reuse is a core part of SpaceX's plan to lower the cost of spaceflight and increase its efficiency.

如此广泛的火箭重复使用是SpaceX降低航天成本和提高效率计划的核心部分。

That already-successful strategy could take a big leap forward soon; the company is developing a giant, fully reusable rocket called Starship, which is designed to help humanity settle Mars. (The Falcon 9 and its close cousin the Falcon Heavy are only partially reusable; their upper stages are expendable.)

这一已经成功的战略可能很快就会向前迈出一大步；该公司正在开发一种名为Starship的巨型、完全可重复使用的火箭，旨在帮助人类定居火星。（猎鹰9号及其近亲猎鹰重型只能部分重复使用；它们的上面级是可牺牲的。）

The Falcon 9's upper stage, meanwhile, will haul the 28 Starlink satellites to LEO today, deploying them about 64 minutes after launch.

与此同时，猎鹰9号的上面级今天将把28颗Starlink卫星拖到低地球轨道，在发射后约64分钟部署它们。
