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

SpaceX 首席执行官埃隆·马斯克 (Elon Musk) 周五详细介绍了其新版星舰版本与上一版本在设计上的差异。

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.

发生了什么：“该船的第 2 版拥有更多的推进剂，减少了干质量并提高了可靠性，”马斯克在 X（前身为 Twitter）上写道。他正在回应一位寻求有关即将推出的新版本运载火箭的答案的用户。

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.

马斯克在后来的帖子中还写道，星舰的目的是搭载很多人进行数万次飞行。 “……所以随着时间的推移，它需要非常可靠。一定会的，”马斯克写道。

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.

马斯克解释说，如果出现孤立的发动机故障，多个发动机可以提高可靠性。马斯克补充说，超重型助推器上有 33 个发动机，甚至比苏联 N1 第一级上的 30 个发动机还要多，Starship 的目标是可靠。

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.

为什么这很重要：在马斯克分享了一张 Starbase 的星舰照片并配上标题“……V1 的最后一个”后，人们对新版本产生了好奇。 SpaceX 最初于 2020 年展示了 Starship 的 V1.0 原型。尽管之前已经建造了各种 Starship 原型，但 V1 原型是专门为轨道测试飞行而设计的。

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

SpaceX 的星际飞船是马斯克实现人类登陆月球和火星愿景的关键要素。

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.

星舰于 11 月 18 日进行了第二次升空，成功实现了级分离。然而，助推器不久后发生爆炸，飞船在到达近150公里的高度后与SpaceX失去联系。它最终未能实现这次试射的最终目标，即往返太空并溅落在太平洋上。
