SpaceX星舰第11次试飞将于10月13日何时发射？如何在线观看？

SpaceX plans to launch the 11th test flight of its Starship megarocket on Monday evening (Oct. 13), and we've got the information you need to tune in live.

SpaceX计划在10月13日（星期一）晚间进行“星舰”巨型火箭的第11次试飞，我们将为您提供实时观看的全部信息。

The Starship Flight 11 test is scheduled to launch from SpaceX's Starbase site in South Texas on Monday (Oct. 13), during a 75-minute window that opens at 7:15 p.m. EDT (2315 GMT; 6:15 p.m. local Texas time). You can watch the liftoff live on this page, courtesy of SpaceX. You can visit our Starship Flight 11 live updates page for the latest info.

“星舰”第11次测试计划于10月13日（星期一）在SpaceX位于美国德克萨斯州南部的星际基地进行，发射窗口为75分钟，将于美国东部时间晚上7点15分开启（格林威治时间23时15分；德州当地时间下午6时15分）。您可以在本页面上观看由SpaceX提供的发射直播。您可以访问“星舰”第11次试飞实时更新页面了解最新信息。

Flight 11 will be the fifth Starship launch of 2025. SpaceX hopes to build on the success of Flight 10, which launched on Aug. 26 and achieved all of its major objectives. (Flight 7, Flight 8 and Flight 9, which also launched this year, were more checkered; SpaceX lost the Starship upper stage prematurely on each of them.) SpaceX intends to settle Mars using Starship, and NASA has tapped the vehicle as the first crewed lander for its Artemis program of moon exploration. But the 400-foot-tall (121-meter-tall) Starship — the biggest and most powerful rocket ever built — is still in the testing phase, and the company hopes Monday's action will get it closer to the finish line.

“星舰”第11次试飞将是2025年的第五次星舰发射。SpaceX希望在第10次试飞成功的基础上再接再厉。第10次试飞于8月26日进行，圆满完成所有主要目标。（而在今年早些时候进行的第7、8、9次试飞则较为曲折——SpaceX在这三次试飞中“星舰”上级都过早分离。）SpaceX打算使用“星舰”实现人类定居火星，而美国宇航局已经选定这款飞行器，作为“阿尔忒弥斯”月球探索计划中的首个载人登月着陆器。但这艘400英尺高（约121米高）的星际飞船——全球最大、推力最强的火箭——仍处于测试阶段，该公司希望周一的试飞能让这一项目离最终目标更进一步。

SpaceX is targeting Monday (Oct. 13), for the launch of Starship Flight 11, with liftoff expected at 7:15 p.m. EDT (2315 GMT). SpaceX has a 75-minute launch window, however, so Starship could fly any time between 7:15 p.m. and 8:30 p.m. EDT (2315 to 0030 GMT).

SpaceX计划于10月13日（周一）进行“星舰”第11次试飞，预计点火起飞时间为美国东部时间晚上7点15分（格林威治时间23时15分）。然而，SpaceX有75分钟的发射窗口，因此“星舰”有可能在美国东部时间晚上7时15分至8时30分之间（格林威治时间23时15分至次日0时30分）发射。

According to local road closure alerts around Starbase, SpaceX has backup Flight 11 launch dates on Tuesday (Oct. 14) and Wednesday (Oct. 15), if Starship can't get off the ground on Monday.

根据星际基地周边发布的道路封闭通知，如果“星舰”无法在周一按计划发射，SpaceX还预留了备用发射日期——分别为周二（10月14日）和周三（10月15日）。

You can watch SpaceX's Starship Flight 11 test launch in a few ways.

您可以通过多种方式观看SpaceX“星舰”第11试飞的直播。

SpaceX will stream the liftoff live via its X account, as well as on its Starship Flight 11 mission page and the X TV app. Coverage will begin about 30 minutes before launch — so, at 6:45 p.m. EDT (2245 GMT), if SpaceX continues to target the beginning of the launch window on Monday.

SpaceX将通过其X帐号、“星舰”第11次试飞任务页面和X TV应用程序直播此次发射。若发射仍按计划在周一的发射窗口开始时进行，直播将在发射前大约30分钟开始，即美国东部时间晚上6时45分（格林威治时间22时45分）。

Space.com will simulcast the SpaceX Flight 11 stream on this page, as well as on our homepage and our YouTube channel.

Space.com将在本页面、其首页以及YouTube频道同步转播SpaceX“星舰”第11次试飞的直播。

If you want a longer livestream, you can check out NASASpaceflight's webcast on YouTube. This stream will begin at about 4:15 p.m. EDT (2015 GMT) and feature live commentary during "go for launch" polling and other key preflight activities.

如果你想观看时间更长的直播，可以前往YouTube收看NASASpaceflight的网络广播。该直播大约将于美国东部时间下午4时15分（格林威治时间20时15分）开始，并会在“确认发射“投票和其他重要发射前活动期间提供现场解说。

Finally, if you're in the area, you can watch SpaceX's Starship Flight 11 in person. SpaceX doesn't have an official launch-viewing site for the public or the media, but you can find a spot yourself.

最后，如果您身处发射区域，还可以现场观看SpaceX”星舰“第11次试飞。虽然SpaceX并未为公众或媒体设置官方的观测地点，但您可以自行选择合适的位置进行观看。

One good option is Cameron County Amphitheater, in Isla Blanca Park on South Padre Island, which provides clear views of Starbase's orbital launch mount from across the water. You can also stake out a place along the shore of nearby Port Isabel.

一个不错的观测地点是位于南帕德里岛伊斯拉布兰卡公园内的卡梅伦县露天剧场，在那里可以清楚地看到对岸星际基地的轨道发射架。您也可以选择在附近的伊莎贝尔港海岸沿线寻找一个观测位置。

Traffic in the area tends to get very heavy in the leadup to a Starship launch, so plan to get to your preferred viewing site early — multiple hours early, if possible.

由于”星舰“发射前该地区的交通往往会变得非常拥堵，建议您尽早前往观测地点——最好提前几个小时到达。

If all goes according to plan, Starship Flight 11 will last just over an hour. The mission will be broadly similar to Flight 10, with ocean landings planned for both Starship stages — the Super Heavy booster and Starship (or "Ship" for short) upper stage. (There will be no "chopsticks" catch of Super Heavy by the Starbase launch tower this time.)

如果一切顺利，”星“第11次试飞将持续一个多小时。此次任务总体上与第0次试飞类似，计划让两级火箭——”超级重型“助推器和”星舰“上级助推器（简称”Ship")——进行海上着陆。（这次星际基地发射塔不会用“筷子式”抓取超级重型火箭。）

"The upcoming flight will build on the successful demonstrations from Starship’s 10th flight test with flight experiments gathering data for the next-generation Super Heavy booster, stress-testing Starship's heat shield, and demonstrating maneuvers that will mimic the upper stage’s final approach for a future return to launch site," SpaceX wrote in a mission overview.

SpaceX在任务概述中写道：“即将到来的试飞将在“星舰”第10次试飞成功的基础上进行，包括通过飞行实验为下一代“超级重型”助推器收集数据，对“星舰”的隔热罩进行压力测试，并模拟演示上级火箭未来返回发射场的最终进近机动动作，”

The Flight 11 Super Heavy already has a launch under its belt — it conducted Flight 8 on March 6, capping its work that day with a successful return to Starbase for a chopsticks catch. Twenty-four of its 33 Raptor engines are veterans of that previous mission, according to SpaceX.

“超级重型”助推火箭已经进行了一次发射——它在3月6日进行了第8次试飞，并在当天成功返回星际基地，由发射塔完成“筷子式”抓取。据SpaceX称，其33台猛禽发动机中有24台曾参与那次任务。

The chief objective for Super Heavy this time around is to test a new landing-burn strategy for the next-generation Starship, a bigger vehicle that's expected to debut early next year. (Flight 11 will be the final launch of the current "Version 2" iteration of Starship.)

此次“超级重型”助推器的主要目标是测试下一代“星舰”的新着陆燃烧策略，这是一款预计明年初首次亮相的更大型飞行器。（第11次试飞将是当前“星舰”V2迭代的最后一次发射。）

"Super Heavy will ignite 13 engines at the start of the landing burn and then transition to a new configuration with five engines running for the divert phase," SpaceX wrote in the mission description.

SpaceX在任务描述中写道：“‘超级重型’助推器在着陆燃烧开始时将点火13个发动机，然后在偏转阶段切换到新的发动机配置，仅启动5台发动机。”

"Previously done with three engines, the planned baseline for V3 Super Heavy will use five engines during the section of the burn responsible for fine-tuning the booster’s path, adding additional redundancy for spontaneous engine shutdowns," the company added. "The booster will then transition to its three center engines for the end of the landing burn, entering a full hover while still above the ocean surface, followed by shutdown and dropping into the Gulf of America."

该公司补充道：“之前使用三台发动机，而V3“超级重型”助推器的计划将在燃烧中使用五台发动机，以微调助推器飞行路径，同时增加对发动机意外关闭的冗余保障。随后，助推器将在着陆燃烧结束时切换到三台中央发动机，在海面上方时进入完全悬停状态，然后关闭发动机并落入美国海湾。”

Ship will fly much farther and longer than Super Heavy on Flight 11. As on Flight 10, the upper stage will deploy eight payloads (dummy versions of SpaceX's Starlink broadband satellites) into suborbital space. This milestone is scheduled to occur over a seven-minute stretch beginning 18.5 minutes after liftoff.

在第11次试飞中，“星舰”上级的飞行距离和时长都将远超“超级重型”助推火箭。。与第10次试飞一样，“星舰”上级将向亚轨道空间部署8颗有效载荷（SpaceX星链宽带卫星的虚拟版）。这一里程碑计划在升空18分30秒后开始，持续约7分钟。

Ship will also briefly reignite one of its six Raptor engines in space a little under 38 minutes into the flight, demonstrating a key capability for a vehicle designed to travel to the moon and Mars.

在飞行约38分钟时，“星舰”上级还将短暂重启其六台猛禽发动机中的一台，以展示这款为前往月球和火星而设计的飞行器的一项关键性能。

In addition, Flight 11 will put Ship's heat shield and other reentry systems to the test, gathering data to pave the way for "chopstick" catches of the upper stage down the road.

此外，第11次试飞还将对“星舰”上级的隔热罩和其他再进入系统进行测试，收集数据，为未来通过“筷子式”方式抓取上级奠定基础。

"For reentry, tiles have been removed from Starship to intentionally stress-test vulnerable areas across the vehicle," SpaceX wrote in the mission description. "Several of the missing tiles are in areas where tiles are bonded to the vehicle and do not have a backup ablative layer. To mimic the path a ship will take on future flights returning to Starbase, the final phase of Starship’s trajectory on Flight 11 includes a dynamic banking maneuver and will test subsonic guidance algorithms prior to a landing burn and splashdown in the Indian Ocean."

SpaceX在任务描述中写道：“为了重返大气层，星舰上的瓷砖已被移除，以有意对整个飞行器的易损区域进行应力测试。一些缺失的瓷砖位于与飞行器粘合的区域，并且没有备用烧蚀层。为了模拟飞船在未来返回星际基地的飞行轨迹，第11次试飞的最后阶段将进行动态倾斜机动，并将在印度洋着陆燃烧和溅落之前测试亚音速制导算法。”

Ship is expected to reenter Earth's atmosphere just under 48 minutes after launch and hit the water off the coast of Western Australia about 18 minutes later.

“星舰”上级将在发射后不到48分钟重新进入地球大气层，并在大约18分钟后落入澳大利亚西海岸海域。

SpaceX has two official backup days for Flight 11 at this point, according to a beach and road closure notice issued by Texas' Cameron County — Tuesday (Oct. 14) and Wednesday (Oct. 15).

根据德克萨斯州卡梅伦县发布的海滩和道路封闭通知，SpaceX目前为第11次试飞预留了两个备用发射日，分别是10月14日（周二）和10月15日（周三）。

The launch windows are likely the same on Tuesday and Wednesday, though we'll have to wait for confirmation from SpaceX on that end.

周二和周三的发射窗口很可能与周一是相同的，但最终时间仍需等待SpaceX官方确认。
