SpaceX could give us a launch doubleheader on Tuesday night (Dec. 12).

SpaceX 可能会在周二晚上（12 月 12 日）为我们带来两次发射。

The company aims to launch 23 more of its Starlink internet satellites from Florida's Cape Canaveral Space Force Station on Tuesday atop a Falcon 9 rocket, during a nearly four-hour window that opens at 11:02 p.m. EST (0402 GMT on Dec. 12). You can watch it live via SpaceX's account on X (formerly known as Twitter), beginning at about five minutes before the window open.

该公司计划于周二利用猎鹰 9 号火箭从佛罗里达州卡纳维拉尔角太空部队站发射另外 23 颗 Starlink 互联网卫星，时间为晚上 11 点 02 分，时间为近四个小时。美国东部时间（12 月 12 日格林尼治标准时间 0402）。您可以通过 SpaceX 在 X 上的帐户（以前称为 Twitter）观看直播，从窗口打开前大约五分钟开始。

SpaceX could have another mission on its docket on Tuesday as well: A Falcon Heavy might launch the U.S. Space Force's X-37B space plane from NASA's Kennedy Space Center, which is next door to Cape Canaveral, that same night. 

SpaceX 还可能在周二执行另一项任务：猎鹰重型火箭可能会在当天晚上从美国宇航局肯尼迪航天中心发射美国太空军的 X-37B 太空飞机，该中心位于卡纳维拉尔角附近。

The X-37B launch and the Starlink liftoff were both originally scheduled for Monday night (Dec. 11), but SpaceX stood down from both of them. The company cited a ground issue for the Falcon Heavy scrub but did not provide a reason for the Starlink push.

X-37B 发射和星链发射原定于周一晚上（12 月 11 日）进行，但 SpaceX 均取消了这两项发射。该公司提到了猎鹰重型火箭的地面问题，但没有提供星链推进的原因。

If all goes according to plan on Tuesday's Starlink mission, the Falcon 9's first stage will come back to Earth for a vertical landing about 8.5 minutes after launch. It will touch down on the droneship "A Shortfall of Gravitas," which will be stationed in the Atlantic Ocean off the Florida coast.

如果周二的星链任务一切按计划进行，猎鹰 9 号的第一级将在发射后约 8.5 分钟返回地球并垂直着陆。它将降落在“A Shortfall of Gravitas”无人船上，该船将驻扎在佛罗里达州海岸附近的大西洋上。

It will be the third launch and landing for this particular booster, according to a SpaceX mission description. Its other two missions were Crew-7 and CRS-29, which sent astronauts and cargo, respectively, to the International Space Station for NASA.

根据 SpaceX 的任务描述，这将是该特殊助推器的第三次发射和着陆。它的另外两项任务是 Crew-7 和 CRS-29，分别为 NASA 运送宇航员和货物到国际空间站。

The 23 Starlink satellites, meanwhile, are scheduled to deploy from the Falcon 9's upper stage into low Earth orbit about 65.5 minutes after liftoff.

与此同时，23 颗星链卫星计划在升空后约 65.5 分钟从猎鹰 9 号的上级部署到近地轨道。

Starlink is SpaceX's internet megaconstellation, which currently consists of more than 5,000 operational spacecraft.

Starlink 是 SpaceX 的互联网巨型星座，目前由 5,000 多艘运行中的航天器组成。

The enormous network has grown a great deal over the past year. SpaceX has launched more than 90 orbital missions in 2023 so far, and most of them have been dedicated to building out the Starlink constellation.

这个庞大的网络在过去的一年里有了很大的发展。到目前为止，SpaceX 在 2023 年已发射了 90 多次轨道任务，其中大部分都致力于建设星链星座。
