科技日报:理性看待商业航天探索中遇到的挫折
Ke Ji Ri Bao· 2025-12-03 23:52
纵观全球火箭回收技术发展历史,首次轨道级回收试验成功是奇迹,失败才是常态。美国SpaceX的"猎 鹰9"火箭2010年首飞,2013年9月开始尝试轨道级垂直返回回收,至少经历4次失败后,才于2015年12月 实现陆上软着陆。之后又经历2次失败,2016年4月才在海上平台回收成功。今年1月,美国"蓝色起 源"公司"新格伦"火箭首次轨道级回收试验也以失败告终,11月才首次实现第一级海上回收。 相比美国,我国商业航天产业起步较晚,技术积累相对薄弱,但商业可回收火箭的研制进展并不慢。 SpaceX起步于2002年,13年后才真正掌握火箭回收技术;"蓝色起源"成立于2000年,25年后"新格伦"火 箭才回收成功。而蓝箭航天创立于2015年,其研制的朱雀三号与猎鹰9号性能相近,部分设计指标甚至 领先,已经进入轨道级回收试验阶段,成绩值得肯定。 12月3日,蓝箭航天朱雀三号遥一运载火箭在东风商业航天创新试验区发射升空,按程序完成飞行任 务,火箭二级进入预定轨道。火箭一子级着陆过程中发生异常燃烧,垂直返回回收试验失败。 此次发射是我国首次进行可回收火箭轨道级发射验证。火箭回收难度极高,需要传感器、栅格舵、飞行 控制算法、可变 ...
白宫可以嘴硬,但发射架从不说谎

Core Viewpoint - SpaceX has become an indispensable player in the U.S. aerospace industry, controlling a significant portion of the market and making it difficult for the government to reduce its reliance on the company despite political tensions with its CEO, Elon Musk [1][18][19]. Group 1: SpaceX's Dominance - SpaceX has established itself as a "space monster," dominating the U.S. launch market and holding a critical position in national security and NASA operations [1][4]. - In 2023, SpaceX conducted nearly 100 launches, capturing over half of the global launch market share, with expectations for continued growth in 2024 and 2025 [5][11]. - The company's innovative technology, such as the reusable Falcon 9 and Falcon Heavy rockets, has drastically reduced launch costs, making it the only company capable of offering competitive pricing, reliability, and launch frequency [5][7]. Group 2: Challenges for Competitors - Traditional aerospace giants like ULA (United Launch Alliance) and Boeing have struggled to compete with SpaceX due to high costs and inefficiencies, with ULA's new Vulcan rocket facing significant delays and issues [11][12]. - New entrants like Blue Origin have not yet proven their reliability, with their New Glenn rocket still in development and facing challenges [12][15]. - The U.S. government has attempted to encourage competition but has found that no other company can currently meet the high demands for reliability and rapid execution required for national security missions [15][19]. Group 3: Government's Dilemma - The U.S. government is caught in a paradox: it wants to reduce dependence on SpaceX while simultaneously relying on the company for critical missions [18][19]. - Despite political frustrations with Musk, the government recognizes that without SpaceX, many of its plans would be stalled, highlighting the company's unique position in the market [18][19]. - The relationship between SpaceX and the government resembles a reluctant partnership, where both parties are interdependent despite their grievances [18][19].
