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

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.

무슨 일이 일어났는가: 머스크는 이전에 트위터였던 X에 "함선의 버전 2는 더 많은 추진제를 보유하고 건조 질량을 줄이며 신뢰성을 향상시킵니다."라고 썼습니다. 그는 발사체의 새로운 버전과 향후 버전에 대한 답변을 찾는 사용자에게 응답하고 있었습니다.

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.

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.

고립된 엔진 고장이 발생할 경우 여러 엔진이 신뢰성을 높여준다고 머스크는 설명했습니다. 머스크는 소련 N1 1단계 엔진 30개보다 훨씬 많은 슈퍼 헤비 부스터의 엔진 33개를 탑재해 스타쉽의 신뢰성을 목표로 하고 있다고 덧붙였습니다.

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.

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

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.

스타쉽은 11월 18일에 두 번째 이륙을 통해 성공적으로 무대 분리를 통과했습니다. 그러나 부스터는 직후 폭발을 겪었고 우주선은 거의 150km 고도에 도달한 후 SpaceX와의 접촉이 끊어졌습니다. 결국 태평양에 물보라를 일으키며 우주까지 왕복 비행한다는 시험 발사의 최종 목표를 달성하지 못했습니다.
