Trump's space transportation policy calls for new spaceport on federal land
摘要
美国总统特朗普签署新版国家太空交通政策，要求开发更多航天发射场，以支持到2030年每年超过1000次发射与再入任务。该政策取代2013年奥巴马时期版本，两者均强调支持商业航天及确保进入太空的能力。政策指出，美国本土轨道发射次数已从2013年的约18次增至去年的176次，其中SpaceX完成165次轨道发射及5次星舰亚轨道试飞。新政策提出，太空运输能力必须扩展
A new national space transportation policy signed by President Donald Trump on Thursday calls for the development of more spaceports to support more than 1,000 launches and reentries per year by 2030.
The presidential memorandum replaces a 2013 policy signed by former President Barack Obama. Both policies share an emphasis on supporting the commercial space industry and underscore the importance of assured access to space. But the launch sector has changed immensely since then. There were 176 orbital launch attempts from US soil last year, nearly 10 times the number in 2013. SpaceX led the pack last year with 165 orbital launches of its Falcon 9 rocket, plus five suborbital test flights of the much larger Starship.
"By 2030, our space transportation ranges must grow to support more than 1,000 launches and reentries every year," the policy says. "The policies set forth in this memorandum will secure America's continued superiority in space."
