SpaceX CEO Elon Musk on Friday detailed the differences in design of its new Starship version as compared to the last.

SpaceX 執行長 Elon Musk 週五詳細介紹了其新版星艦版本與上一版本在設計上的差異。

What Happened: “Version 2 of the ship holds more propellant, reduces dry mass and improves reliability,” Musk wrote on X, formerly Twitter. He was responding to a user seeking answers on the new and upcoming version of the launch vehicle.

發生了什麼：「該船的第 2 版擁有更多的推進劑，減少了乾質量並提高了可靠性，」馬斯克在 X（前身為 Twitter）上寫道。他正在回應一位尋求即將推出的新版本運載火箭的答案的用戶。

Musk, in a later post, also wrote that Starship is intended to carry a lot of people on tens of thousands of flight. “…so needs to be extremely reliable over time. It will be,” Musk wrote.

馬斯克在後來的貼文中還寫道，星艦的目的是搭載許多人進行數萬次飛行。 「…所以隨著時間的推移，它需要非常可靠。一定會的，」馬斯克寫道。

In case of an isolated engine failure, multiple engines increase reliability, Musk explained. With 33 engines on the Super Heavy booster, which is even more than the 30 engines on Soviet N1 first stage, Starship is aiming to be reliable, Musk added.

馬斯克解釋說，如果出現孤立的引擎故障，多個引擎可以提高可靠性。馬斯克補充說，超重型助推器上有 33 個發動機，甚至比蘇聯 N1 第一級上的 30 個發動機還要多，Starship 的目標是可靠。

Why It Matters: The curiosity around the new version comes after Musk shared a photo of starships at Starbase captioned, “…the last of V1.” SpaceX initially presented the V1.0 prototype of the Starship in 2020. Although various Starship prototypes have been constructed previously, the V1 prototype was specifically designed for an orbit test flight.

為什麼這很重要：在馬斯克分享了一張 Starbase 的星艦照片並配上標題「…V1 的最後一個」後，人們對新版本產生了好奇。 SpaceX 最初於 2020 年展示了 Starship 的 V1.0 原型。儘管之前已經建造了各種 Starship 原型，但 V1 原型是專門為軌道測試飛行而設計的。

SpaceX's Starship is a pivotal element in Musk's vision of landing humans on the Moon and Mars.

SpaceX 的星際飛船是馬斯克實現人類登陸月球和火星願景的關鍵要素。

The Starship had its second liftoff on Nov. 18, successfully navigating stage separation. However, the booster experienced an explosion shortly afterward, and the spacecraft lost contact with SpaceX after reaching an altitude of nearly 150 kilometers. It eventually failed to fulfill the test launch's ultimate goal of a round-trip flight to space with a splashdown in the Pacific Ocean.

星艦於 11 月 18 日進行了第二次升空，成功實現了級分離。然而，助推器不久後發生爆炸，飛船在到達近150公里的高度後與SpaceX失去聯繫。它最終未能實現這次試射的最終目標，即往返太空並濺落在太平洋上。
