Latest estimate for Starship launches required to support a Moon landing? 22.
摘要
NASA未公开为支持载人登月所需的星舰发射具体次数，该数字多年来不断变化。NASA通常表示无法确定而不愿给出确切数值。2023年，时任人类着陆系统主管Lisa Watson-Morgan称有大致概念但不愿透露。文章探讨了为星舰月球着陆器在近地轨道加注燃料、使其飞往月球着陆并返回月球轨道所需的发射次数估算问题。
NASA does not have, nor want, nuclear weapons. But when it comes to a particular metric that is part of the Artemis Program to land people on the Moon, NASA guards a particular number like they are trying to prevent outsiders from cracking nuclear codes.
I am speaking of the number of Starship launches required to fuel a Starship-based lunar lander in low-Earth orbit such that it can fly out to the Moon, land there, and return to lunar orbit.
This number has been a moving target over the years. The general response from NASA has typically been, 'We don't know for sure, so we're not going to say.' In 2023, for example, the then-director of NASA's Human Landing System, Lisa Watson-Morgan, told Ars, "We have a general idea, but I’m reluctant to say exactly what that is."
