星舰第四次发射成功返回，我们重发这篇文章。 文丨 贺乾明 李梓楠 编辑丨黄俊杰 美国东部时间 6 月 6 日，SpaceX 第四次发射星舰（Starship）太空船。飞船进入轨道，并重返大 气层，按计划落入印度洋海域。 商业公司以相对低成本提供媲美登月火箭的运载能力，是商业太空探索的一次大跨越。SpaceX 计划 在后续的测试飞行中尝试平稳回收利用发射火箭，进一步降低成本。装载新发动机的第二代星舰也 在准备中。 今年 3 月，星舰首次成功进入近地轨道后坠毁， 我们发文 介绍了 SpaceX 如何建立新的研发、生产 体系，支持星舰的诞生。现在我们根据最新进展调整部分内容，重发这篇文章。 2011 年夏天，美国国会和美国宇航局（NASA）共同宣布了一个宏伟的计划：投入 180 亿美元，开 发前所未有的巨型火箭和新飞船，重整载人航天，也为之后登陆火星做准备。 这是一个理所当然的 "举国体制" 项目。国会拨巨资、政府机构（NASA）设目标，让合作几十年的 军工巨头们推进。 几个月后，NASA 从庞大的预算里拨了个零头（不到 3 亿美元）给 SpaceX、蓝色起源等四家商业公 司，让他们尝试做出能自负盈亏的载人飞船。分 ...
