該公司需要更換一個柵格鰭執行器，導致延誤一天。

We'll have to wait at least one more day to see Starship's second-ever flight.

我們至少還要再等一天才能看到星艦的第二次飛行。

SpaceX had been targeting Friday morning (Nov. 17) for the second test launch of its huge Starship rocket. But that's no longer the plan.

SpaceX 定於週五上午（11 月 17 日）對其巨型星艦火箭進行第二次試射。但這不再是計劃。

"We need to replace a grid fin actuator, so launch is postponed to Saturday," company founder and CEO Elon Musk announced today (Nov. 16) via X (formerly known as Twitter). (Grid fins are the waffle-iron-like structures on Starship's Super Heavy first stage, which help the booster steer its way back to Earth.)

公司創始人兼執行長 Elon Musk 今天（11 月16 日）透過X（以前稱為Twitter）宣布：「我們需要更換網格鰭執行器，因此發布推遲到週六。 」 （網格鰭是星艦超重型第一級上的華夫餅鐵狀結構，有助於助推器返回地球。）

Liftoff from SpaceX's Starbase site in South Texas is now scheduled to occur during a 20-minute window that opens Saturday at 8 a.m. EST (1300 GMT; 7 a.m. local Texas time), according to a company mission description. You can watch it live here at Space.com when the time comes. 

根據該公司的任務描述，目前計劃在美國東部時間週六上午8 點（格林尼治標準時間1300；德克薩斯州當地時間上午7 點）開始的20 分鐘時間內從SpaceX 位於德克薩斯州南部的Starbase 基地升空。屆時您可以在 Space.com 上觀看直播。

Starship is SpaceX's next-generation deep-space transportation system, which the company is developing to take people and cargo to the moon, Mars and beyond.

Starship 是 SpaceX 的下一代深空運輸系統，該公司正在開發該系統，旨在將人員和貨物運送到月球、火星和其他地方。

The vehicle consists of two elements, both of which are designed to be fully and rapidly reusable: The giant Super Heavy first stage and a 165-foot-tall (50 meters) upper-stage spacecraft known as Starship.

該飛行器由兩個部分組成，這兩個部分都被設計為可完全快速地重複使用：巨大的超重型第一級和一個165 英尺高（50 公尺）的上級航天器，稱為“星艦” 。

Together, the duo make the biggest and most powerful space vehicle ever built. When fully stacked, Starship stands nearly 400 feet (122 meters) tall.

兩人共同打造了有史以來最大、最強大的太空飛行器。完全堆疊後，Starship 高度接近 400 英尺（122 公尺）。

A fully stacked Starship has flown just once to date, on an April 20 test flight from Starbase that aimed to send the upper stage partway around Earth. Splashdown was targeted for the Pacific Ocean near Hawaii, but the upper stage never got to fly freely; it failed to separate from Super Heavy, and SpaceX detonated the vehicle high above the Gulf of Mexico four minutes after liftoff.

迄今為止，一艘滿載的星際飛船僅飛行過一次，是在 4 月 20 日從 Starbase 進行的一次試飛中，目的是將上級送至地球周圍。 Splashdown 的目標是夏威夷附近的太平洋，但上層從未自由飛行；它未能與超重型分離，SpaceX 在升空四分鐘後在墨西哥灣上空引爆了該飛行器。

The goals of Saturday's flight are broadly the same as those of the April 20 mission. If all goes according to plan, Super Heavy will come down for a water landing in the Gulf of Mexico about seven minutes after liftoff.

週六飛行的目標與 4 月 20 日任務的目標大致相同。如果一切按計畫進行，「超重」號將在升空後約七分鐘降落在墨西哥灣水上著陸。

The Starship upper stage, meanwhile, will get close to orbital velocity as it makes a partial circuit of our planet. It will splash down near Hawaii about 90 minutes after launch. 

同時，星艦上級在繞地球部分運行時將接近軌道速度。發射後約 90 分鐘，它將濺落在夏威夷附近。
