ESA considers righting the wrongs of Ariane 6 by turning it into a Franken-rocket
摘要
欧洲航天界已形成共识，需发展可重复使用火箭，但具体路径与投入仍未确定。当前讨论多集中于研发全新火箭以替代仍采用一次性模式的阿里安6号。欧洲航天局正通过资金支持新兴公司验证小型火箭能力，并激励火箭升级以提升运力，同时与欧盟及各国政府资助垂直起降技术演示项目。然而这些努力缺乏统一协调，进展缓慢。
It took a while, but a consensus has emerged in Europe that the continent's space industry needs to develop reusable rockets. How to do it and how much to spend on it remain unresolved questions.
Much of the discourse around reusable rockets in Europe has focused on developing a brand new rocket that might eventually replace the Ariane 6, which debuted less than two years ago but still uses the use it and lose it model embraced by the launch industry for most of the Space Age.
The European Space Agency (ESA) is offering money to emerging rocket companies in Europe to prove their small satellite launchers can do the job. ESA is also making money available to incentivize rocket upgrades to haul heavier cargo into orbit. ESA, the European Commission, and national governments are funding rocket hoppers to demonstrate vertical takeoff and vertical landing technologies. While there is significant money behind these efforts, the projects are not unified, and progress has been slow.
