2024年，埃隆·马斯克将星舰（Starship）实现完全可重复使用作为SpaceX的核心目标之一。星舰是目前全球体积最大、推力最强的运载火箭系统，由超重型助推器（Super Heavy）和星舰飞船组成。马斯克多次强调，只有实现全系统的快速、低成本重复使用，才能大幅降低太空发射成本，为火星殖民等长期愿景奠定基础。今年，SpaceX已进行多次星舰试飞，重点测试助推器和飞船的回收能力。在最近的飞行中，超重型助推器成功完成了“返场着陆”（boost-back burn）并尝试在发射塔上用机械臂捕获，而星舰飞船也首次实现了受控再入大气层并溅落印度洋。尽管尚未完全成功回收两者，但这些进展显著缩小了与“完全可重复使用”目标的距离。马斯克表示，若能在年内完成一次完整的、无需重大翻修即可再次飞行的往返任务，将标志着航天史上的重大突破。这不仅对NASA的阿尔忒弥斯登月计划至关重要，也将推动商业太空旅行和深空探索的发展。
In 2024, Elon Musk has made achieving full reusability of Starship a top priority for SpaceX. Starship is currently the world’s largest and most powerful launch vehicle, consisting of the Super Heavy booster and the Starship spacecraft. Musk has repeatedly emphasized that only through rapid and low-cost reuse of the entire system can launch costs be drastically reduced—essential for long-term goals like colonizing Mars.This year, SpaceX has conducted multiple Starship test flights, focusing on recovering both the booster and the spacecraft. In recent missions, the Super Heavy successfully executed a boost-back burn and attempted to be caught mid-air by mechanical arms at the launch tower, while the Starship spacecraft achieved its first controlled atmospheric re-entry and splashdown in the Indian Ocean. Although full recovery of both stages hasn’t yet been accomplished, these milestones bring SpaceX significantly closer to full reusability.Musk stated that completing a fully successful round-trip mission this year—one where both stages return intact and require minimal refurbishment before relaunch—would mark a historic breakthrough in spaceflight. This achievement would not only support NASA’s Artemis moon missions but also accelerate commercial space travel and deep-space exploration.
