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

SpaceX 可能會在周二晚上（12 月 12 日）為我們帶來兩次發射。

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.

該公司計劃於週二利用獵鷹 9 號火箭從佛羅裡達州卡納維拉爾角太空部隊站發射另外 23 顆 Starlink 網路衛星，時間為晚上 11 點 02 分，時間為近四小時。美國東部時間（12 月 12 日格林尼治標準時間 0402）。您可以透過 SpaceX 在 X 上的帳戶（以前稱為 Twitter）觀看直播，從視窗開啟前大約五分鐘開始。

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 也可能在周二執行另一項任務：獵鷹重型火箭可能會在當天晚上從美國宇航局肯尼迪航天中心發射美國太空軍的 X-37B 太空飛機，該中心位於卡納維拉爾角附近。

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 發射和星鏈發射原定於週一晚上（12 月 11 日）進行，但 SpaceX 均取消了這兩項發射。該公司提到了獵鷹重型火箭的地面問題，但沒有提供星鏈推進的原因。

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.

如果週二的星鏈任務一切按計劃進行，獵鷹 9 號的第一級將在發射後約 8.5 分鐘返回地球並垂直著陸。它將降落在“A Shortfall of Gravitas”無人船上，該船將駐紮在佛羅裡達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.

根據 SpaceX 的任務描述，這將是該特殊助推器的第三次發射和著陸。它的另外兩項任​​務是 Crew-7 和 CRS-29，分別為 NASA 運送太空人和貨物到國際太空站。

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.

同時，23 顆星鏈衛星計畫在升空後約 65.5 分鐘從獵鷹 9 號的上級部署到近地軌道。

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

Starlink 是 SpaceX 的網路巨型星座，目前由 5,000 多艘運作中的太空船組成。

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.

這個龐大的網絡在過去的一年裡有了很大的發展。到目前為止，SpaceX 在 2023 年已發射了 90 多次軌道任務，其中大部分都致力於建造星鏈星座。
