美国伊利诺伊州Essay代写:太空中的第一架私人飞机

在SpaceShipOne之前,太空旅行只有通过整个国家的集体愿望才能实现。毕竟,1961年4月12日,前苏联的太空计划将人类引入太空,而美国自己的国家航空航天局八年后又将其推向了第一个将人类登上月球的国家。由于垄断性的法律限制和平均航天飞机任务成本高达4.5亿美元,私人企业几乎没有动力去追求商业航天。这一切都是在21世纪的转折时期发生的。届时,美国政府通过1984年商业空间发射法案等立法扭转了重大障碍,为私营公司开发和测试消耗性发射系统开辟了机会。当时,立法主要是为了鼓励运输卫星的进步。 1990年发射服务购买法案指示美国航天局在必要时征求公司的发射服务也消除了一个重大障碍。这种放松管制的趋势促使大批企业家加大对正在形成的新型太空竞赛的投资。 2000年,亚马逊创始人兼首席执行官杰夫贝佐斯成立了Blue Origin,这是一家航空航天创业公司,旨在开发使太空旅行成为现实的技术。两年后,当时的PayPal Elon Musk首席执行官推出了一家竞争公司SpaceX。不甘示弱的是,维珍的亿万富翁创始人兼首席执行官理查德布兰森于2004年跟随他自己的商业空间部门 美国伊利诺伊州Essay代写:太空中的第一架私人飞机 Before SpaceShipOne, space travel was only possible through the collective aspirations of entire nations.

With monopolistic legal restrictions and an average shuttle mission cost topping $450 million, private enterprise had little incentive to pursue commercial spaceflight. That all changed around the turn of the 21st century. By then, the U.S. government had reversed significant barriers through legislation such as the Commercial Space Launch Act of 1984, which opened up opportunities for private companies to develop and test expendable launch systems. At the time, the legislation was meant primarily to encourage advancements for transporting satellites. The 1990 Launch Services Purchase Act, which directed NASA to enlist launch services from companies...
